Step-by-step explanation:
PEMDAS! I love PEMDAS problems!
1. (63 - 3) / 6 + 42
(P means parenthesis first - after you do this step the parenthesis goes away)
60 / 6 + 42
(We have no exponets so we move on to doing division and multiplication from left to right)
10 + 42
(Now we add!)
52
2. (8*4+5^2) + 8
(Now we have to do PEMDAS inside the parenthesis - So we have to do exponents first)
(8*4 + 25) + 8
(Now you do multiplication from left to right)
(32 + 25) +8
(Now that we only have one sign in our parenthesis we can solve it to get rid of it.)
67 + 8
(now add!)
75
3. (13 + 5)^2 + 8 / 2
(We have to do parenthesis first because of the P)
18^2 + 8/2
(now we do exponents)
324 + 8 / 2
(Now we divide and multiply from left to right)
324 + 4
(now add!)
328

99 - 74 = 25 25 / 99 = 0.25 0. 25 × 100 = 25.25%From $99 to $74, it is 25.25 percent decrease.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, $99 and $74.
From 99 to 74 it is decreased
Difference 99-74=25
Now, 25/99 ×100
= 0.2525×100
= 25.25%
Therefore, from $99 to $74, it is 25.25 percent decrease.

Answer:
y= 1/4x -3
Step-by-step explanation:
point-slope form: y-y1=m(x-x1)
y-2=1/4(x-4)
y-2= 1/4x - 1
y= 1/4x - 3
The equation of a line in point-slope form with slope 1/4 and point (4, 2)
is y - 2 = (1/4)(x - 4).
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
The equation of a line is point-slope form is y - y₁ = m(x - x₁).
Given, Slope is 1/4 and has point (x₁, y₁) = (4, 2).
∴ The equation of the given line is y - 2 = (1/4)(x - 4).

A function is a relationship between inputs where each input is related to exactly one output.
f(1) = 97
f(2) = 194
f(3) = 291
Where f(x) is the calories burned.
x is the number of miles walked.
Yes, the given relation in the table is a function.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Function:
Miles walk = input
Calories burned = output
We know that,
A function can have many-to-one and one-to-one.
A function can not have one-to-many.
Now,
From the table,
f(1) = 97
f(2) = 194
f(3) = 291
We see that the relation is a function.
The relation is a one-to-one relation.
Thus,
The given relation in the table is a function.
