(length of the foot) = 0.860 • (length of the forearm) + 3.302
If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.
Using this equation, how long would the foot of a person be if his forearm was 17 inches long?

Answers
x=foram
A. easy, plug 17 for x and evaluage for y
y=0.860(17)+3.302
y=14.62+3.302
y=17.922 inches
B. rate of change is slope
y=mx+b
m=slope
so
rate or change is 0.860 inches per legnth of forarm
C. what data
D. it is a function
since it is 1st degree (no exponents greater than 1 on the placeholder), and it is not a vertical line
it is a function
Step-by-step explanation:
Part A:
y=0.860x + 3.302
y= 0.860(17) + 3.302
y= 14.62 + 3.302
y= 17.922
Part B:
step 1
y=0.860x + 3.302
y= 0.860(17) + 3.302
y= 14.62 + 3.302
y= 17.922
step 2
y=0.860x + 3.302
y= 0.860(18) + 3.302
y= 15.48 + 3.302
y= 18.782
step 3
18.782-17.922=.86
So, the rate of change is .86
Hope it helps!!

140% of what number is 56
Answers
The value of the unknown number is 40.
What is the value of the unknown number?
Given the parameter:
"140% of what number is 56"
Let's represent the unknown number as "x."
To find the number that represents 140% of a certain value, simply set up an equation.
140% of the number = 56
140% of x = 56
140% × x = 56
First, convert the percent to decimal:
140% = 140/100 = 1.4
Now, we have:
1.4 × x = 56
Solve for x.
Divide both sides of the equation by 1.4:
x = 56/1.4
x = 40
Therefore, the value of x is 40.
