2(4x-1) + 3(3-2x)=0
distribute
8x-2+9-6x=0
add like terms
2x+7=0
subtract 7 from both sides
2x= -7
divide both sides by 2
x=-7/2

Pick the correct answer <br> Please help thanks :)

Answer:

B

Step-by-step explanation:

First create the equation that has slope of -1 in the form of y=mx+b. Because the slope is -1, m=-1, so the equation is y=-x+b. Now we see that we are given the point (-3, 8) as an intersection point. Substitute x and y for -3 and 8 in our equation. With this information, our equation becomes 8=3+b. Solving, b=5. Our equation is now y=-x+5.

Simplifying all of the answer choices, we have

A. y=-x-5

B. y=-x+5

C. y=-x-5

D. and E. as what they already show

The only answer that matches is B.

schepotkina [342]

Answer:

c

Step-by-step explanation:

the formula is \frac{y_{2}-y_{1} }{x_{2} -x_{1}}

When we plug that in we get \frac{-3-2}{6- (-4)} = \frac{-5}{10} = -\frac{1}{2}

Hope this helps!
