Step-by-step explanation:
step 1. (13x + 8) + (2x + 7) = 180 (definition of same side interior angles)
step 2. 15x + 15 = 180 (like terms)
step 3. 15x = 165 (subtract 15 from each side)
step 4. x = 11. (divide both sides by 15)
That is point slope form
y-y1=m(x-x1)
passes through the point (x1,y1) and has a slope that is m
Answer:
y-9=2(x-3)
Step-by-step explanation:
The point-slope formula is: y-y1=m(x-x1)
y1 and x1 is where you plug in the coordinate and m is the slope.
y1 is the second number of the coordinate (x, y)
So, y1 is 9 in this case
x1 is the first number of the coordinate (x, y)
So x1 is 3 in this case
Do you get it or do I need to explain further?
The rate of first tree's height = 3 + 1x
Of second tree = 4 + 0.5x
Where, x = number of years.
So, 3 + 1x = 4 + 0.5x
1x - 0.5x = 4 - 3
0.5x = 1
x = 1/ 0.5
x = 2
In short, Your Answer would be 2 Years
Hope this helps!
Answer: 49°F
Step-by-step explanation: x - 12 = 37, So all we have to do is reverse it. That means we add 37 and 12 to get the beginning temperature. 37 + 12 = 49. So at the beginning of the evening, it was 49°F.
