Rate of change is another way to say slope. To find the slope of a line, use this formula:
m = (y2-y1)/(x2-x1) where m is the slope, and (x1, y1) and (x2, y2).
To find the slope of the function in the table, take two coordinates (I’ll use (-1, 5) and (1,9)) and plug them into the slope formula.
m = (9-5)/(1+1) = 4/2 = 2
The slope/rate of change equals 2. The only equation in the answer choices where the slope is 2 is A, so A is the answer
Answer:
The value of x=-8
Step-by-step explanation:
x+8=f(x)
f(x)=0
x+8=0
x=-8

Answer: substitution
Step-by-step explanation:
Substitute 3 in for x for all equations.
3(3)+4 = 13
8(3)-1 = 23
3(3)+4 =13
Add all of the sides together to find the perimeter
13+23+13 =49
Answer:
All u have to do is divide those numbers and see what they have in common.
Step-by-step explanation:
To find a mean proportional. There are various uses of the square root, one of which is to find a mean proportional between any two numbers, which is performed thus: Multiply the two given numbers together, then extract the square root out of their product, and it will be the mean proportional sought.
