<span>If m = 7x + 7, m = 4y, and m = 112
since m = 112
112 = 7x + 7
112 - 7 = 7x
105= 7x
x = 15
112 = 4y
y = 28</span>
Answer:
y= 3x+5
Step-by-step explanation:
start with the linear equation formula
y= mx+b
indentify what you already have.
x= -1 and y= 2 and m(slope)= 3
We are solving for b, so plug in what you have.
2= 3(-1)+b
Simplify.
2= -3+b
Add 3 on both sides.
5= b
Rewrite your equation with the x and y values.
y= 3x+5
Answer:
Step-by-step explanation:
we know that
An equilateral triangle has three equal sides and three equal interior angles (the measure of each interior angle is equal to 60 degrees)
see the attached figure to better understand tyhe problem
Let
h ----> the height of an equilateral triangle
b ---> the length side of an equilateral triangle
In the right triangle ABD
Applying the Pythagorean Theorem

substitute the given values

square root both sides
The answer to your question is 7.94 that the perfect square root of 63
