Replace x with -1, and y = 9

Therefore, (x²y)/-7 becomes (-1² · 9)/-7

-1² is just 1, and 1 × 9 is just equal to 9, so your final answer is -9/7.

H(x) = 5.7 −19x<br><br> A. <br> -127.3<br> B. <br> -138.7<br> C. <br> 0.67<br> D. <br> 138.7
Vilka [71]

Answer:

x = 0.3 (see below)

Find the x intercept/zero.

To find x intercept/zero, subsitute H (x) = 0.

0 = 5.7 - 19x

Move the variable to the left hand side and change the symbol.

19x = 5.7

Now, divide both sides.

x = 0.3

Solution is 0.3

Alternate solution is x = 3/10.

Hope it helps!

Solve for x<br> 0.5(5−7x)=8−(4x+6)<br> x = ???
leonid [27]
Hello!

0.5 (5 - 7x) = 8 - (4x+6)
2.5 - 3.5x = 8 - 4x + 6
2.5 - 3.5x = 2 - 4x
-3.5x + 4x = 2 - 2.5
0.5x = -0.5
X = -1

Your answer is x = -1. I hope this helps!
