Answer:
The system x = 4 and y = -x - 1 has one solution
Step-by-step explanation:
x = 4 and y = -x - 1 intersects only once on the graph
<h3>
Answer: Choice C</h3>
================================================
Work Shown:
Reference angle = P
Opposite side = QR = 8.5
Adjacent side = QP = 16
tan(angle) = opposite/adjacent
tan(P) = QR/QP
tan(P) = 8.5/16
tan(P) = 0.53125
tan(P) = 0.53
Answer:
-4432.5 m
Step-by-step explanation:
Displacement is measured in meters, so will be the product of velocity in m/s and time in s.
(-98.5 m/s)×(45.0 s) = -4432.5 m
___
If you're concerned with significant figures, you can round this to -4430 m, which has the required 3 significant figures.
Answer:
11. 10, 20,30,40,50,60,70
12. 35, 45,55,65,75,85,95
Step-by-step explanation:
10 dollars per week for 7 weeks in equivalent to 10x7 which equals $70.
If you already had $25 you would do 10x7+25. Using PEMDAS you would multiply first (10x7=70) then add 25 (70+25=95)
