Answer:
3x + y = -1
Step-by-step explanation:
y-5=-3( x+2)
once you distribute, you get y-5=-3x-6
then, add 5 to each side and get y=-3x-1 (this is slope intercept form)
finally, add 3x to each side to get 3x+y=-1 (standard form: Ax + By = C)
Answer:
Step-by-step explanation:
1. Here are two five-pointed stars. A student said, “Both figures A and B are polygons. They are both composed of line segments and are two-dimensional. Neither have curves.” Do you agree with the statement? Explain your reasoning.
Two five-pointed stars, labeled A and B. Star A is composed of a pentagon surrounded by five small triangles. Star B is a single shape with one continuous perimeter.
2. Here is a five-sided polygon. Describe or show the strategy you would use to find its area. Mark up and label the diagram to show your reasoning so that it can be followed by others. (It is not necessary to actually calculate the area.)
A grid.
Answer:
x=18
Step-by-step explanation:
let the number =x
then
x²-124=200
x²=200+124
x²=324
x=18
Answer:
B. x^2
