A linear function forms a line when graphed.
Y - 2x = 2 ....put in y = mx + b form
y = 2x + 2
In y = mx + b form, the slope will be in the m position and the y intercept will be in the b position.
y = 2x + 2.....so we have a slope(m) of 2, and a y int (b) = (0,2)
the x intercept can be found by subbing in 0 for y and solving for x
0 = 2x + 2
-2x = 2
x = -2/2
x = -1......so the x int is (-1,0)
go ahead and plot ur intercepts....(-1,0) and (0,2)......and since ur slope is 2, start at (-1,0) and go up 2 spaces and to the right 1 space, then up 2 and to the right 1........thats ur line and it crosses the y axis at (0,2)
Answer:
89
Step-by-step explanation:
Use the mean formula, mean = sum of elements / number of elements.
He wants to keep his average at 85 or higher, so plug in 85 as the mean. Let x represent the score he has to get, and solve for x:
mean = sum of elements / number of elements.
85 = (85 + 76 + 94 + 81 + x) / 5
85 = (336 + x) / 5
425 = 336 + x
89 = x
So, he has to get a 89.
Answer:
7 x 10^7
Step-by-step explanation:
count the zeros
Answer:
The answer is D, 30.4
Step-by-step explanation:
Because the two parallelograms are similar, the relationship between the sides of them are directly proportional.
So:
Cross multiply
8x = 243
÷8 both sides
x = 30.375 ≈ 30.4
The answer is D, 30.4
