Answer:
the top left picture is a function
Step-by-step explanation:
it is a function because the line does not go over the same x-value more then once.
Answer:
2.5
Step-by-step explanation:
when you 5x automatically cancels, and 7.5 / 3 is 2.5
Answer:
4
Step-by-step explanation:
Lets start by plugging in our (a) value
a^2 + 5a + 4
(-5)^2 + 5(-5) +4
25 - 25 + 4
0 + 4
4 is your final answer!
Answer:
The equation of the line would be y + 4 = -1/8(x + 6)
Step-by-step explanation:
To find the point-slope form of the line, start by finding the slope. You can do this using the slope formula below along with the two points.
m(slope) = (y2 - y1)/(x2 - x1)
m = (-4 - -5)/(-6 - 2)
m = 1/-8
m = -1/8
Now that we have the slope, we can use that along with one of the points in the base form of point-slope.
y - y1 = m(x - x1)
y + 4 = -1/8(x + 6)
perimeter = sum of all sides
27 = 9+7.8+x
x (third side) = 10.2
