What is the solution for x in the equation -4x+5x-7=10+3x-2x

1 answer:

4 0

You combined the x’s together then u wanna move all the x’s to one side then after that you would want to do the opposite of -7, so then you add 7 to 10 and then you would divide everything by 2 and get x=8.5

3.14 is used for pi.

6. r = $\sqrt{\frac{A}{\pi } }$

14.00

7. d = $\frac{c}{\pi }$

5.00

8. d = $2 \sqrt{\frac{A}{\pi } }$

23.01

9. r = $\frac{c}{2\pi }$

20.01

10. d $\pi$ = $2 \sqrt{{A}$

31 $\pi$

11. r $\pi$ = $\frac{c}{2}$

22.5 $\pi$

Hope this helps :)

F(-4) for f (x) = -4x+9<br>f(-4)=?

Dovator [93]

F(x)= -4x+9

Multiply f*x

xF=9+4x

Solve for X: -4x+xF=9+4x-4x=0

Combine like terms: -4x+4x=0

-4x+xF=9+0= 9

-9+-4x +xF = 0.

1.) 1.5m/8m= fg/32m
2.) 1.5 (32)= 8m * fg
3.) 1.5 (32)/8m= fg
4.) 6m = fg

Im pretty sure that's right
