Answer:
A. y=10x+50
Step-by-step explanation:
you only add $50 once because it is the "become a member fee", you put a X next to the 10 because its monthly. (so you can replace the variable with any number if needed)
Answer:
Step-by-step explanation:
45.6
Answer:

Step-by-step explanation:
There are 99 - 10 + 1 = 90 numbers between 10 and 99
There are 18 numbers that have at least one two digit.

Answer:
(-4,18)
Step-by-step explanation:
First, plug in -4 for x in the equation to solve for y, y = -2*-4+10, y = 8+10, y = 18. Now, you have the x and y coordinate for the point (-4,18).
The length of the line segment BC is 31.2 units.
<h2>Given that</h2>
Triangle ABC is shown.
Angle ABC is a right angle.
An altitude is drawn from point B to point D on side AC to form a right angle.
The length of AD is 5 and the length of BD is 12.
<h3>We have to determine</h3>
What is the length of Line segment BC?
<h3>According to the question</h3>
The altitude of the triangle is given by;

Where x is DC and y is 5 units.
Then,
The length DC is.

Squaring on both sides

Considering right triangle BDC, use the Pythagorean theorem to find BC:

Hence, the length of the line segment BC is 31.2 units.
