Find the difference
\(( - {3x}^{3} - {7x}^{2} + 5x - 4) - ( {6x}^{2} - 8)\)
​

Simplifying

17 = 11y + 12x

Reorder the terms:

17 = 12x + 11y

Solving

17 = 12x + 11y

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-12x' to each side of the equation.

17 + -12x = 12x + -12x + 11y

Combine like terms: 12x + -12x = 0

17 + -12x = 0 + 11y

17 + -12x = 11y

Add '-17' to each side of the equation.

17 + -17 + -12x = -17 + 11y

Combine like terms: 17 + -17 = 0

0 + -12x = -17 + 11y

-12x = -17 + 11y

Divide each side by '-12'.

x = 1.416666667 + -0.9166666667y

Simplifying

x = 1.416666667 + -0.9166666667y

Answer: look at the picture

Step-by-step explanation: hope this help :)

The slope 1/2 means that if you start at any point on the line and go to the right two and up one, you will hit the line again. That means the there are an infinite number of parallel lines that can have 1/2 as their slope. Each one has a formula (y=mx+b is the general slope-intercept formula, with b being the height at which that line crosses the y axis) using 1/2 as its m, and the b changes to show the y-intercept for that particular line. As an example, y=1/2x+2 is a line with the slope we described and it crosses the y axis at (0,2). Raise the value of b and the line moves to the right (and keeps the same slope, or lean). Reduce the value of b, and it slides to the left.

A supplementary adds up to 180 degrees. It would be complementary because it adds up to 90 degrees.

Step-by-step explanation:

Answer:

A supplementary adds up to 180 degrees. It would be complementary because it adds up to 90 degrees.

Sorry had to do this for points ^ - ^

y - -2x - 6 (1)
y = x+15 (2)

From (2) we get x = y-15
We put that in (1) and we get -2(y-15)-6 = y
-2y+30-6 = y
-2y+24=y
-2y+24-y=0
-3y+24 = 0 ==> -3y = -24 ==> y = 8

We put that value in (2) and we get x = 8-15 = -7

Now in order to verify this, we replace the variables and see if (1) = (2)

y = -2x - 6 ==> (-2 * -7) - 6 = 14-6 = 8 (1')
y = x + 15 = -7 + 15 = 8 (2')

(1') = (2') ==> the solution is x = -7 and y = 8

Answer:

x=−2y=2

Step-by-step explanation:

Take the value of x from the first equation:x=2−2y (1)and substitute for x into the second:y=2(2−2y)+6

solve for y ;y=4−4y+6y=105=2

Substitute back into

(1) and find :x=2−4=−2

Answer:

1.6 liters of lemonade

Step-by-step explanation:

There are 1000 milliliters in one liter so she made 8000 milliliters of lemonade

Next we have to figure out how many milliliters of lemonade she sold each day:

Saturday: 200 milliliters of lemonade in a glass * 8 glasses = 1600 milliliters of lemonade sold

Sunday:  200 milliliters of lemonade in a glass * 24 glasses = 4800 milliliters of lemonade sold

1600  + 4800 = 6400 total milliliters of lemonade sold

Since there are 1000 milliliters in one liter, we have to divide 6400 by 1000:

6400 ÷ 1000 = 6.4 liters

Lastly, we have to subtract 6.4 from 8:

8 - 6.4 = 1.6 liters of lemonade

Hope this helps!

Step-by-step explanation:

\(( {4}^{ - 3} ) ^{ - 3} = {4}^{9} \)

\(( { - 4}^{9} ) ^{2} = ( - 4) {}^{18} \)

\(( {4}^{6} ) ^{ - 3} = \frac{1}{{4}^{18}} \)

\(( { - 4}^{9} ) {}^{2} = ( { - 4})^{18} \)

Answer:

3,5

Step-by-step explanation:

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

m/-2=13-5

m/-2=8

m=8*-2

m=-16

Answer:

ok for this we have to multiple the sides of the presents

10.5*16=168

34*23=782

7*7=49

now we add then together

49+782+168=999

so the stuff covers a area of 999 square cm

please give brainlest since this took a while

Answer:

1272 cm

Step-by-step explanation:

Multiply: 10.5*16=168

34*23=782

7*7=49

21*13=273

Add: 168+782+49+273=1272

Plug in units: 1272 cm

Step-by-step explanation:

The difference beteen 9.2 ounces and 8.1 ounces is  1.1 ounces

   and the difference in price is   .49

       so 1.1 ounces cost .49

           $ .49 / 1.1 oz = $  .445  per ounce

Then Reid's bowl should cost   7.8 oz  * $ .445 / oz = $3.47
