Solve -1.2x+2.5=0.8x+6.5<br>x=2<br>O<br>x=-4 0​
Bond [772]

Answer:

x = - 2

Step-by-step explanation:

Given

- 1.2x + 2.5 = 0.8x + 6.5 ( subtract 0.8x from both sides )

- 2x + 2.5 = 6.5 ( subtract 2.5 from both sides )

- 2x = 4 ( divide both sides by - 2 )

If f(x) = 3x² tlo, what is f(-7)?
tia_tia [17]

Answer:

Step-by-step explanation:

Be careful how you handle this.

f(-7) = 3(-7)^2

f(-7) = 3* 49     Notice the minus sign disappears. That's because there are 2 of them.

f(-7) = 147

leva [86]

If you want it to be a slope intercept form, the first you have to find slope.

y2-y1/x2-x1

2-0/6-0

2/6 = 1/3

Then you need to find the y intercept. Plug in the x and y value in y=mx+b.

2=1/3(6)+b

2=2+b

0=b

ANSWER: y=1/3x+0

Hope this helps and is correct :)
