Answer:

10-5x=3\left(x-4\right)-2\left(x+7\right)

3\left(x-4\right)-2\left(x+7\right)

combine like terms:-

=3x-12-2x-14

3x-2x=x

=x-12-14

Subtract -12 -14

=x-26

10-5x=x-26

Subtract 10 from both sides:-

-5x=x-36

Now, subtract x from both sides:-

-5x-x=x-36-x

-6x=-36

Divide both sides by -6:-

\frac{-6x}{-6}=\frac{-36}{-6}

x=6

Answer:

x=6

Step-by-step explanation:

10-5x=3(x-4)-2(x+7)

Distribute

10-5x=3x-12-2x14

Combine like terms

10-5x = x-26

add 5x to each side

10-5x+5x = x+5x-26

10 = 6x-26

Add 26 to each side

10+26 = 6x-26+26

36 = 6x

Divide by 6

36/6 = 6x/6

6 =x

Pls help asap <br><br> Which quadratic function is represented by the graph?
DiKsa [7]

Answer:

1st option

Step-by-step explanation:

From the graph the zeros are x = - 3 and x = 1 , then the corresponding factors are

(x + 3) and (x - 1) , so

y = a(x + 3)(x - 1) ← a is a multiplier

To find a substitute a point on the graph into the equation

Using (0, - 1.5 ) , then

- 1.5 = a(3)(- 1) = - 3a ( divide both sides by - 3 )

0.5 = a

Then

f(x) = 0.5(x + 3)(x - 1)
