Answer:
Step-by-step explanation:
First of all, I drawed this graph and uploaded it for you...
We know that a line equation is y = ax + b and I want to know which equation goes through the points (-1, -5) and (1, -1).
Let's put these points in the algebreac expression of line to find the correct equation:
-5 = a. (-1) + b
-1 = a.(1) + b
solving this system of equation by elimination, we find 2b = -6 and b = -3.
Then, -5 = -a + (-3)
-a = -5 + 3
a = 2
Finally, our line equation is y = 2x - 3
The slope also is represented by a. So, the slope is 2.
4x + 10= 2x - 6
Subtract 2x on both sides
4x - 2x + 10 = 2x - 2x - 6
4x - 2x + 10 = -6
2x + 10 = -6
Subtract 10 on both sides
2x + 10 - 10 = -6 - 10
2x = -6 - 10
2x = -16
x = -8
Answer:
26 shots.
Step-by-step explanation:
60% of 42 is 25.2 but you can't make .2 of a shot so you have to round up.
Answer:
2750
Step-by-step explanation:
It is 2750 because there is 100cm in 1m, which means if you do 27.5 times 100 you will then get the answer of 2750.
