Answer: A
You’re basically adding m - 2 nine times
So it’s 9m - 18
Or 9m - 9(2)
123 - Use PEMDAS but since you have both division and multiplication you can just go from left to right
Answer:
15
Step-by-step explanation:
25% of 20 is 5 5*3=15
Answer:
Step-by-step explanation:
Width = 5v - 4w
Length = 3v + 7w
Perimeter = 2*(length + width)
= 2* (3v + 7w + 5v - 4w)
= 2* (3v + 5v + <u>7w - 4w)</u> {Combine like terms}
= 2* (8v + <u> 3w)</u>
= 2*8v + 2*3w
= 16v + 6w
Answer:
domain: -2 < x < 4
range: -∞ < y < 9
Step-by-step explanation:
domain: because the domain is all of the x-values, just look for the furthest one to the left, which is -2, and then look for the one that is furthest to the right, it being 4.
range: because the quadratic function has the two arrows continuing downwards, toward the negative portion of the graph, it would be -∞. Then look for the maximum of the graph, which would be considered the most highest part of the graph, which is seen on the graph as 9.
