Y-7=-2(x-4)
y-7=-2x+8
y=-2x+15
5/4 you do the multiple add combo and then multiply straight across
Answer:
68 and 7
Step-by-step explanation:
You need to multiply both sides of the equation by the reciprocal of 3/4. The reciprocal is 4/3 and 4/3 multiplied by 9 = 12. So x = 12 because a number times the reciprocal is one.
Answer:
(B) f(x) has a greater maximum value than g(x).
Step-by-step explanation:
Given ![f(x) = -8x^2 + 7](https://tex.z-dn.net/?f=f%28x%29%20%3D%20-8x%5E2%20%2B%207)
First, we determine the maximum point of f(x).
f(x) is at maximum at the point of symmetry, i.e. where ![x=-\dfrac{b}{2a}](https://tex.z-dn.net/?f=x%3D-%5Cdfrac%7Bb%7D%7B2a%7D)
a=-8, b=0
![x=-\dfrac{0}{2*-8}=0](https://tex.z-dn.net/?f=x%3D-%5Cdfrac%7B0%7D%7B2%2A-8%7D%3D0)
![f(0) = -8(0)^2 + 7=7](https://tex.z-dn.net/?f=f%280%29%20%3D%20-8%280%29%5E2%20%2B%207%3D7)
- The maximum point of f(x) is (0,7)
- The maximum point of g(x) is (2,6)
Therefore, f(x) has a greater maximum value than g(x).
<u>The correct option is B.</u>
