Answer:
a.6.66
b.384
c.860
d.166
Step-by-step explanation:
To find the product of 8 and 6 work out 8 multiplied by 6 which is 48
Average rate of change is just the slope between the 2 points
we can do this the long way or the smart way
long way, find the 2 points and find the slope between them
when x=-5, f(-5)=-2(-5)+1=10+1=11
when x=1, f(1)=-2(1)+1=-2+1=-1
so the points are (-5,11) and (1,-1)
the slope between them is (-1-11)/(1-(-5))=(-12)/(1+5)=-12/6=-2
the answer is B, -2
smart way
recognize that that is a linear equation and the slope between any 2 points will be the m in y=mx+b
f(x)=-2x+1
the slope is -2
the average rate of change is -2
answer is B. -2
Answer:
f(x) = x² + 5
General Formulas and Concepts:
<u>Algebra I</u>
- Equality Properties
- Function Notation
Step-by-step explanation:
<u>Step 1: Define</u>
y - x² = 5
<u>Step 2: Rewrite</u>
- Add x² to both sides: y = x² + 5
- Rewrite <em>y</em>: f(x) = x² + 5
Answer:
y = 2 x = -7
Step-by-step explanation:
2x+5y=-4 2x + 5y = -4 Add both equations
(-x-3y=1)2 -2x - 6y = 2
-y = -2
y = 2
Plug in 2 for y in the equations
-x - 3(2) = 1
-x -6 = 1
-x = 7
x = -7
