Answer:
(-3,3)
Step-by-step explanation:
Using elimination:
Multiply the first equation by 8 and the second by 5 which equals
40x+56y=48
-40-60y=-60
Now you add them together
40x+(-40x)=0 so that crosses out
56y+(-60y)= -4y
48+(-60)=-12
You now have -4y=-12
Divide by -4
y=3
Now plug in y to any of the equations
5x+7(3)=6
5x+21=6
Subtract 21 from both sides
5x=-15
Divide by 5
x=-3
Your final solution is (-3,3)
Answer: Exactly One Solution
Step-by-step explanation: All you have to do is evaluate the problem.
9z - 6 + 72 = 162 - 6
9z - 6 + 72 = 156
9z + 66 = 156
9z = 90
z = 10
The true statements about the functions are:
- g(x) has the maximum greatest value.
- h(x) has a range of all negative numbers.
<h3>How to determine the true statements?</h3>
The complete question is in the attached image
From the image, we have:
- g(x) has the greatest maximum value of 7 1/2
- All the values of h(x) are negative
- All the values of f(x) are positive
This means that the true statements about the functions are g(x) has the maximum greatest value and h(x) has a range of all negative numbers.
