Answer:
A. x=2, y = 7.
B. (2, 7).
Step-by-step explanation:
A. You can eliminate y by subtracting the equations:
y = 8x - 9
y = 4x - 1 Subtract:
0 = 4x - 8
4x = 8
x = 8/4 = 2.
Now substitute for x in the first equation:
y = 8(2) - 9 = 7.
Check in the second equation:
y = 4x - 1
7 = 4(2) - 1 = 7. Check is OK.
B. On the graph they will intersect at the point (2, 7).
They will intersect here because the values x=2 and y=7 satisfy both the 2 equations.
Answer:
a. 15m
b. 7m
Step-by-step explanation:
- perimeter is the sides added up, there are four sides of a square, and all sides are equal
- equation s+s+s+s or s•4 (s=sides)
- so to find the length with the perimeter divide perimeter by 4
- 60/4=15
- the area of a square is s²
- so take the square root of the area
- √49=7
Answer: 2.0
Step-by-step explanation:
To round 1.965 to the nearest tenth consider the hundredths’ value of 1.965, which is 6 and equal or more than 5. Therefore, the tenths value of 1.965 increases by 1 to 0.
1.965 rounded to the nearest tenth = 2.0

First, we must find the unit price:
20.25/3=6.75
Now we divide:
47.25/6.75=7
I hope you are having a great day, buddy :)
