Answer:
Equation of a line has form of y = ax + b
This line passes (-8, 8) and (1, 10), then:
-8 = -8 x a + b
10 = a + b
Subtract 2nd equation to 1st equation, then:
18 = 9 x a
=> a = 2
=> b = 10 - 2 = 8
=> y = 2x + 8
Hope this helps!

F(x)=4x²+6
This parabola intersects y-axis at y=6 ==>f(0) =
if g(x) is translated 4 units down that means the intersection with y-axis will be :
6-4 = 2 ; hence g(x) =4x² + 2
Answer:
triangle A= 1/2bh
1/2(18)(14)= 126
semi circle 3.14(9)^2 divided by 2 = 127.17
Triangle Area plus semi circle Area = 126+127.17= 253.17
Answer:
40% number of calories have increased
Step-by-step explanation:
Old Value ( Calories consume before) = 2000
New Value (increase in Calories consumed) = 2800
We need to find by what percent did the number of calories increase
To find percent increase, the formula used is:
Putting values in formula and finding percent increase
So, 40% number of calories have increased
