Answer:
Step-by-step explanation:
first, we need to change 2 2/5 into a decimal
2 2/5
100/5 = 20
2/20=40
2 2/5 = 2.4
let subtract 2.4 from 4.7
4.7-2.4=2.3
therefor x < 2.3
A middle school club is planning a homecoming dance to raise money for the school. Decorations for the dance cost $100, and the club is charging $10 per student that attends.
Which graph describes the relationship between the amount of money raised and the number of students who attend the dance?
The amount of money raised and the number of students who attended the dance will be directly proportional to each other, meaning both are positively dependent on each other. This type of a relationship is called a linear relationship, which can be represented by a type of graphical method called the "linear graph".
To accurately represent the data, on the x axis you need to plot the the number of students attending the dance; and on the y axis you need to plot the amount raised and you'll obtain a positive slope of 10.
The starting point of the graph would have the coordinates (0,100) or x = 0 and y = 100, because even if there are no students attending the event, the decoration cost of 100 dollars would still have to be paid.
The equation for the same should be written as: Amount of money raised = 10 x no. of students + 100

The scatter plot shows the relationship between the amount of time, in hours, students in a Spanish class slept the night before an exam and their score on the exam.
Which of the following describes the pattern of association for the scatter plot?
There is a positive linear association.
There is a positive nonlinear association.
There is a negative linear association.
There is a negative nonlinear association.
Answer: Positive Nonlinear Association
Step-by-step explanation:
Take a look at the graph. From what we can see, it is going up. Hence, it's positive (meaning C and D are not the answer).
The way to tell between linear and nonlinear is the line. If you can perfectly fit all the points on a straight line, then it is linear. Clearly, you can't fit all the points on a singular straight line here, so it is nonlinear.

Step-by-step explanation:
What is the y-intercept of a line that has a slope of -3 and passes through point (-5, 4)? a) -17 b) -11 c) 7 d) 19
Answer:
(- 11)
Answer b is correct
Step-by-step explanation:
To find this you can use
y = mx + c
Here,
m = slope
c = y - intercept
( -5, 4) = ( x ,y)
Let us solve now .
\(y = mx + c\)
\(4 = - 3 \times - 5 + c \\ 4 = 15 + c \\ 4 - 15 = c \\ - 11 = c\)
Therefore,
c = (-11)
That means y - intercept is ( -11 )

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

When you add 6 to the product of a number and 10, the result is 36. What is the number?
A) 3
B) 6
C) 2
D) 4
Answer: the number is 3.
Step-by-step explanation:
(x × 10) + 6 = 36
[(3) × 10] + 6 = 36
Answer:
3
Step-by-step explanation
First let's create an equation
Let x = number
Product is outcome of multiplication
The product of 10 and a number can be written as 10x
Were supposed to add 6 to the product and that should equal 36
So the equation is 10x + 6 = 36
We now solve for x using basic algebra
10x + 6 = 36
Subtract 6 from both sides
10x = 30
Divide both sides by 10

Simplify (7x2− 2x + 9) + (3x2+ 15x − 4)
Answer:
10x^2+13x+5
Step-by-step explanation:
(7x^2− 2x + 9) + (3x^2+ 15x − 4)
Combine like terms
(7x^2+3x^2− 2x+ 15x + 9 − 4)
10x^2+13x+5
Answer:
\(10x^{2} + 13x + 5\)
Step-by-step explanation:
In this equation, you need to add all the like terms. For example, 7x² and 3x² are like terms, since they both are being squared.
First find the like terms:
7x² + 3x²
-2x + 15x
9 - 4
Now simplify the above equations.
7x² and 3x² is equal to 10x². You only have to add the whole number, the exponent stays the same.
-2x + 15x is equal to 13x. Since -2 is negative, you can simply take away two from 15, which is 13, making it 13x.
9 - 4 is equal to 5.
Now add everything together.
\(10x^{2} + 13x + 5\)
Your answer is 10x² + 13x + 5.

(8,1) (15,2) (22,3) (29,4) (36,5) (43,6)
Step-by-step explanation:
Answer:
Step-by-step explanation:
The equation y=7x+1 is written in slope intercept form. That would be:
y=mx+b
m is the slope
b is the y intercept, or where the line first is seen on the y axis.
Because b=1, the y intercept is 1.
Because m=7, the slope is 7.
STEP 1: GRAPH THE Y INTERCEPT.
Since b=1, the line crosses the y intercept when y=1. So graph y=1 on the coordinate plane.
STEP 2: GRAPH THE SLOPE
Do this by going up 7, then right 1. Because 7 is a positive number, you go up.

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Step-by-step explanation:
3 (2x - 5) = 21
=> 6x - 15 = 21
=> 6x = 21 + 15
=> 6x = 36
=> x = 36 / 6
=> x = 6
OR
3 (2x - 5) = 21
=> 2x - 5 = 21 / 3
=> 2x - 5 = 7
=> 2x = 7 + 5
=> 2x = 12

You should eat at least 2,000 calories per day. Today, you have eaten a total of 1,200 calories and you plan to eat pizza for dinner. If each slice of pizza is 352 calories. How many slices of pizza should you eat for dinner?
Answer:
Step-by-step explanation:
We know you need at least 2,000 calories, and we have eaten 1,200 of those. To find how many we have left we need to subtract the calories we have eaten from our goal (Shown below)
\(2000 - 1200 = 800\) calories we have left.
Now we know each slice of pizza is 352 calories, and we need 800 calories. If we divide 800calories remaining by 352calories a slice, we can find how many slices of pizza we need to eat.
\(800 / 352 = 2.27\) slices of pizza needed to meet the minimum calorie requirement.
Good luck getting exactly 2.27 slices of pizza. Because we need a minimum of 2.27 slices, we should round up to 3 slices to get all the calories needed for the day.
Answer: 3 slices of pizza for dinner
Banana Cupcakes

cup vegetable oil
1 large egg
4 tablespoons sour cream
2 medium-sized ripe bananas, mashed
1 cups all-purpose flour
1 teaspoon baking soda
teaspoon salt
1 teaspoon vanilla extract
pinch of nutmeg
You will use the recipe above to answer the following questions:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
