Answer:
1. I am not sure about the first one. I tried everything and nothing I got from any of my work is looking right.
2. AB = 5
3. 8
The slope is the coefficient of x, which is 10, and the y-intercept is the constant, which is 5.
Answer:
x=77
Step-by-step explanation:
Since both triangles are congruent, the angles will also be equal. Hence, x=77 degrees.
Answer:
D. a line graph
Step-by-step explanation:
Since 16 and 25 are perfect squares you can factor the first part.
4^2-5^2(b+3)^2
=(4-5(b+3))(4+5(b+3))
=(4-5b-15)(4+5b+15)
=(-11-5b)(19+5b)
Which can be expanded if necessary,
= -209+150b-25b^2
