Answer:
Step-by-step explanation:
You know that the x-axis is horizontal, so it has slope = 0.
Point-slope equation for line of slope 0 that passes through (-7,9):
y-9 = 0(x+7)
y = 9
Answer:
x=12
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
5x+8x+2x =180
Combine like terms
15x = 180
Divide by 15 on each side
15x/15 =180/15
x=12
One value of x could be 58.
4y+6
The given expression is 8(1/2y+3/4)
To make it easier put 8/1, so we can multiply fractions without getting confused.
First step is 8/1•1/2, for the numerator or top, we have 8•1=8. The denominator or bottom, we have 1•2=2. Now we put them back together like a puzzle. The numerator is 8, and the denominator is 2. So we put eight over two 8/2. Eight divided by two equals four. 8/2=4
So far we've solved for the first half. Don't forget the variable at the end of the first section!
We have 4y+(3/4) now.
But we don't stop there. The eight on the outside of the parenthesis also apply to 3/4.
Same thing we put 8/1 and multiply top and bottom against 3/4.
8•3=24, for the numerator or top value.
1•4=4 for the denominator or bottom value. We combine them back into a fraction, so we have 24/4. Now we don't stop there. We need to simplify the fraction so twenty four divided by four equals six, or 24/4=6.
We plug it back into the original equation with both our new answers, leaving us with 4y+6
The completely simplified answer is 4y+6
