Answer:
the answer seems right to me
A triangle bow is like a piece of the bow that's looped.
The linear equation for the number of cookies he receives, for x hours practicing the piano, is:

A <u>linear function</u> has the format given by:

In which:
- m is the slope, which is the rate of change.
- b is the y-intercept, which is the value of y when x = 0.
In this problem:
- We have two points: (5,15) and (10,20).
- The slope is given by <u>change in y divided by change in x</u>, then:

Then

Point (5,15) means that when
, which is used to find b.


The, the function is:

A similar problem is given at brainly.com/question/16302622
Answer:
We can easily say the x intercepts are +3 and -7
Or we can multiply (x-3) * (x+7)
x^2 + 4x -21 = 0
a = 1 b = 4 c = -21
We solve with the quadratic equation
x = 3
x = -7
So that proves our answers are correct.
Step-by-step explanation:
Number 52 is B.
Number 53 is one hundred sixty-two and thirty-five hundredths.
Number 54 is 1.6235 * 10^.
