If the equation is y = -3x+6 and y=9, substitute 9 for y then solve for x.

9 = -3x + 6 (subtract 6 from both sides)
3 = -3x (divide each side by -3)
-1 = x

(-1,9) is the solution.

we have

<u>The system of equations</u>

y=-3x+6 -------> equation 1

y=9 -------> equation 2

Substitute equation 2 in equation 1

9=-3x+6

subtract 6 both sides

9-6=-3x+6-6

3=-3x

Divide by -3 both sides

x=-1

the solution is the point (-1,9)

therefore

the answer is

the solution to the system of equations is the point (-1,9)

Which is one of the transformations applied to the graph of f(x) = x2 to change it into the graph of g(x) = 9x2 – 36X?
Fiesta28 [93]
Assuming I understand your question correctly, in that you’re looking for just some descriptions of the differences between the functions. If so, then I’d say:

First graph both functions, the f(x) and the g(x). Then spot the differences.
Note that the g(x) function has shifted towards the right compared with the f(x) function.
Another way that the g(x) differs from the f(x) function is that it’s stretched. The vertex is in the IV quadrant for g(x) rather than at the origin for f(x).

I hope that helps.

If 5&lt;2x+3&lt;11, what is the possible range of value of -4x-6
Lady bird [3.3K]

Answer:

-10 > (-4x - 6) > -22

Step-by-step explanation:

Given inequality is 5 < 2x + 3 < 11

Now we will multiply this inequality by (-2) resulting,

5(-2) > (2x + 3)(-2) > 11(-2)

-10 > (-4x - 6) > -22 (Sign of inequality gets reversed when the inequality is multiplied or divided by a negative number)

Therefore, the possible range of (-4x - 6) is between -22 and -10.

The area of the square hole is 8 square centimeters. The volume of a cube shaped block is 64 cubic centimeters. Which edge lengt
damaskus [11]

<u> case a)</u> The area of the square hole is 8 square centimeters

we know that

the area of a square is equal to

A=b^{2}

where

b is the length side of the square

in this problem we have

A=8\ cm^{2}

<u>Find the length side b</u>

b^{2} = 8 \\b= \sqrt{8} \ cm\\b= 2\sqrt{2} \ cm

<u>the answer Part a) is</u>

the length side of the square is 2\sqrt{2} \ cm

Part b) The volume of a cube shaped block is 64 cubic centimeters

we know that

the volume of a cube is equal to

V=b^{3}

where

b is the length side of the cube

in this problem we have

V=64\ cm^{3}

<u>Find the length side b</u>

b^{3} = 64 \\b= \sqrt[3]{64} \\b= 4\ cm

therefore

<u>the answer Part b) is</u>

the length side of the cube is 4\ cm
