Answer:
Final graph is attached.
Solution is x=2, y=3
Step-by-step explanation:
As we have to solve by graphing to let's graph y=2x-1 first.
we are free to plug any number for x say x=0 and x=2
when x=0 then y=2x-1 changes to
y=2(0)-1=0-1=-1
Hence point is (0,-1)
Similarly
when x=2 then y=2x-1 changes to
y=2(2)-1=4-1=3
Hence point is (2,3).
Now we graph both points (0,-1) and (2,3) then join them by a straight line.
We repeat exactly same process for other line y=-x+5 and get points (0,5) and (2,3)
Now graph both to see the intersection point of both lines
We see that both lines intersect at point (2,3)
<u>Hence final answer is (2,3) or we can also write x=2, y=3.</u>
Answer:
A) 9
Step-by-step explanation:
No. of hours required: 4×27 = 108
If 6 machines working:
108÷6 = 18 hours
27 - 18 = 9 hours fewer
Answer:
C = 132°
Step-by-step explanation:
(5y + 28) = 12y
5y - 5y + 28 = 12y - 5y
28 = 7y
y = 4
12 (4)
= 48
48 + C = 180°
48 - 48 + C = 180 - 48
C = 132°

Answer:
B
Discussion:
A. = 3.5 * (1/5) and 3.5 is NOT an integer
B. = 6 * (1/5) and 6 is an integer
C. = (1/4)* (1/5) and (1/4) is NOT an integer
D. = (1/5)*(1/5)* (1/5) = (1/25)(1/5) and )1/25) is NOT an integer
Thank you,
