Given set: x greater than or equal to -1
The interval includes -1 and all the values greater than -1, to graph it put a full point in the -1 and draw an arrow to the the right of -1:
<h2>Interval notation:</h2>
X + 3 +2 > 15
Subtract 2 from both sides
X + 3 > 13
Subtract 3 from both sides ;)
X > 10
Answer:
n = 3
Step-by-step explanation:
9{n+2(n-2)} = 45
Start with the numbers on the inner most pair of parentheses
Multiply (n-2) by 2
9[n+2n-4] = 45
Add what is inside the parentheses
9[3n-4] = 45
Multiply
27n-36 = 45
Add 36 to both sides
27n = 81
Divide both sides by 27
n = 3
Hope this helps!
Problem 1
Answer: Choice A
Vertically stretching it by a factor of 2 is the same as compressing it horizontally by a factor of 2
====================================================
Problem 2
Answer: choice B
Add up the functions to get
M(s) + L(s) = (225+0.65s) + (54 + 1.15s)
M(s) + L(s) = (225+54) + (0.65s+1.15s)
M(s) + L(s) = 279 + 1.80s
