A computer company created this graph to show how many computers it expects sell based on how much money you spend on internet advertising. The company expects
sell 40 million computers, spending $5 million on Internet advertising. What set of units and scales are appropriate for the two axes?
Answer:
Horizontal axis will have number of computers in millions and vertical axis will have advertising dollars in millions.
Given information:
The graph of computer production and advertising amount spent is given in the question.
Total number of computer sell = 40 millions
Cost of internet advertising = $5 million
Now , by looking the graph one can conclude that, Y coordinate of the graph is 40 million and the X coordinate of the graph is $5 million.
Hence, from the above conclusion one can write as:
Horizontal axis (X-axis) is the number of computers and the Vertical axis is (Y-axis) the advertising cost of computers.

Answer:
4 eggs were left over
Step-by-step explanation:
initial number of eggs = 12
number of eggs used to bake 1 loaf of challah:
= 2 eggs
total number of eggs used to bake 4 loaves of challah:
= 4 × 2 = 8 eggs
hence to find the number of remaining eggs:
initial egg number - total number of eggs used
= 12 - 8
= 4
therefore 4 eggs were left over

Answer:
33.3%
Step-by-step explanation:
There are 3 sections the spinner can land on, and only one meets the requirement (less than 3, so the 2 section is the only one). Therefore the chance of landing on 2 is 1/3, or 0.333...... which can be converted into percentage by multiplying it by a hundred.
-0.333..... x 100 = 33.33333....

PLS HELP 50 POINTS What is the discount and sale price of an $84 item that has been discounted at 8.33%?
Answer:
original price = $84
discount percent = 8.33%
discount = 8.33% of $84 = 8.33 × 84 / 100 = $7
Sale price = $84 - $7 = $77
solve: 7 - 2x = 2 (x - 4) - 1

Step-by-step explanation:
determine the intercept of the line
Answer:
X intercept is (-8,0), Y intercept is (-6,0)
Step-by-step explanation:
The intercept is where the line crosses the X and Y axis, so in this line, the line crosses the x axis at (-8,0) and the y axis at (-6,0).
Answer:
There are two different intercepts in this linear line. The x - intercept would be at (-8, 0), and the y - intercept would be at (0,-6). To find out which is the x - intercept and which is the y - intercept, remember that x is always horizontal and y is always vertical.

Using a directrix of y = −2 and a focus of (2, 6), what quadratic function is created?
here are the answers given
\/
f(x) = −one eighth (x − 2)2 − 2
f(x) = one sixteenth (x − 2)2 + 2
f(x) = one eighth (x − 2)2 − 2
f(x) = −one sixteenth (x + 2)2 − 2
Answer:
f(x)=1/16(x-2)^2+2
Step-by-step explanation:
The Equation can be written like this:
f(x) = 1/(4p)(x -h)^2 +(k-p)
where (h, k) is the focus, and p is half the distance between focus and directrix. Here, (h, k) = (2, 6) and p=(6-(-2))/2 = 4. So the equation is ...
f(x) = 1/16(x -2)^2 +2

What is the value of x?
11 (9 - 2x) = -(12x + 11)
Answer:
x=11
Step-by-step explanation:
First Distribute 11 to 9 and -2x
Then distribute the negative to 12x and 11
Then calculate like terms
-22x + 12x = -11 -99 which comes out to -10x=-110
Then divide each side by -10
Your answer will then be x=11

The cost of the fabric is $1.31. What would you expect to pay for a similar piece of fabric that is 18 inches by 42 inches?
Answer: Calculate areas for 2 rectangles;
21*9= 189
18*42= 756
make an equation with data you have;
If 189 cost $1.31
756 cost $x
____________
756 *1.31 / 189 = $5.24 cost for second fabric
Second way;
(18x42) / (21x9) = 4 x 1.31 = $5.24
