Answer:
no estoy segura como se debe responder
1 (x + 2y = -20) ----> x*2y= -20
-1 (x + 3y = -27) ----> x-3y= 27
(0) x + (-1) y = 7
Answer:
The building is 187.5 feet tall.
Step-by-step explanation:
A nearby person is 6 feet tall, and casts a shadow that is 8 feet long.
This means that the relation between the real height and the shadow is given by:

A tall building casts a shadow that is 250 feet long. How tall is the building?*
The real height is three fourths of the shadow. So

The building is 187.5 feet tall.
Answer:
Rotation of 180 degrees, either direction
Dilation, making it smaller by some factor(we aren't given measurements so we cannot be exact)
Then move the figure to the right and then move the figure up
Step-by-step explanation:
12 years. That is the most representative because it's the median.
Answer:
y = 4
Step-by-step explanation:
I assume you want to find the slope-intercept form of the given information.
We are given the slope and a point, so we can find the y-intercept.
y = 0x + b
4 = 0(-2) + b
4 = 0 + b
4 = b
Put everything we know/solved for back into the formula [ y = mx + b ]
y = 4
Best of Luck!
