Answer: Y = 4, X=4 (4,4)

Step-by-step explanation: You must multiply both equations so the leading coefficient cancels out. I’m multiplying both equations by both coefficients so I multiply the entire first equation by -2 so the first equation will be the negative coefficient and the second equation will be multiplied by positive 9 so the negative and positive equations cancel out.

STEPS IN MATH:

1. (9x-8y=4) -2 = -18x + 16y = -8

(2x-3y=-4)9 = 18x-27y= -36

2. ADD THESE EQUATIONS TOGETHER NOW

-18x+16y=-8

+ 18x-27y=-36

0-11y= -44

-11y=-44

DIVIDE -44 by -11y

The final answer is Y= 4

NOW pick an equation to plug in y to, any equation works

I chose the first one, so 9x-8(4)=4

9x-32=4

9x=36

x=4

If h(-8), find 1/3*h(x) = x^2-5x+7
Lynna [10]

The value is 333

<h3>How to determine the function</h3>

From the information given, we have:

  • x = - 8
  • 1/3*h(x) = x^2-5x+7

Now, let's substitute the value of 'x' in the function:

1/3*h(x) = x^2-5x+7

1/ 3 × h(-8) = ( - 8)² - 5 ( -8) + 7

Make 'h ( -8)' the subject of formula

h ( -8) = \frac{( -8)^2 - 5(-8) + 7}{1/ 3}

h ( -8) = \frac{64 + 40+ 7 }{1/ 3}

Take the sum of the numerator

h ( -8) = \frac{111}{1/3}

Take the inverse of the denominator and multiply

h ( -8) = 111 × 3/ 1

h ( -8) = 333

We can see that through the substitute of the value of x as - 8, we get 333

Thus, the value is 333
