Answer:
a.
Step-by-step explanation:
this is a line going from -infinity to +infinity in x and in y direction.
for b or c to be right the function would have to be a single point, as nothing else is valid as value.
It’s b. Because the number with out the x is the y-interact which is -2 then to find the other number I look at the graph and find another point and then count the rise/run which is rising 2 running 3 and it’s also positive that’s why it’s b.
Answer:
B.
Step-by-step explanation:
Total surface area of the square pyramid

Answer:
vertical angles
Step-by-step explanation:
15-b=4b-5(5-3)
Multiply the bracket by -5
(-5)(5)=-25
(-5)(-3)=15
15-b=4b-25+15
15-b=4b-10
Move 15 to the other side
Sign changes from +15 to -15
15-15-b=4b-10-15
-b=4b-25
Move 4b to the other side.
-b-4b=4b-4b-25
-b-4b=-25
-5b=-25
divide both sides by -5
-5b/-5=-25/-5
Answer: b=5
