Answer: x= 5 and y= -2 or (5,-2)
Step-by-step explanation:
108 < 75 + 0.60m
108 - 75 < 0.60m
33 < 0.60m
33 / 0.60 < m
55 < m...or m > 55...company A will charge less if it is driven 56 or more miles
Answer:
4m
Step-by-step explanation:
We are looking for the circumference
We need to find the radius
r = d/2 = 1.2/2 = .6
C = 2*pi*r
C = 2*pi*(.6)
C = 1.2*pi
We can approximate pi by 3.14
C =1.2*3.14
C =3.768 m
To the nearest meter
C = 4m
We call m the slope<span> or gradient of the </span>line<span>. It </span>represents<span> the change in y-value </span>per<span> unit change in x-value. For example, consider the </span>line<span> given by the equation y = 2x + 1. Here are some points on the </span>line<span>. ~hope that helps</span>
Answer:
1. If x=5, 3*5=15, 15*15=225 + y (3) = 228.
2. If y=4, then 10*4 = 40, 4^2 is 16, so 40 + 16 is 56.
I might be wrong, but the first one you answered, x^2, x= 1/2, I think that is wrong. when something is squared, you don't go, "Oh, well since 1/2 equals 1, that's the answer." The way to figure out something like this is... 1/2 times 1/2, which is .25, or 1/4. Another example: 3^5 . The way to find this out is 3*3*3*3*3 = 243. But you don't go 3*5, because that answer would be 15, which is not correct.
