Answer:
-1.14
Step-by-step explanation:
m-9.84 = -10.98
-1.14
you know this because
-1.14+-9.84= -1.14-9.84=-10.98
Answer:
m=-3/4
Step-by-step explanation:
First locate two points that are on solid intersections, (-3, 2) and (1, -1).
<u>y2</u><u>-</u><u>y1</u>
Then use x2-x1' where -1 is y2, 2 is y1, 1 is x2, and -3 is x1.
Plug in numbers, <u>-1-2</u><u> </u>= <u>-</u><u>3</u>
1+3 = 4
-3/4 is m (Slope).
3(2x - 1) > = 4(2x - 3) - 3
6x - 3 > = 8x - 12 - 3
6x - 3 > = 8x - 15
6x - 8x > = -15 + 3
-2x > = -12
x < = -12/-2
x < = 6
the incorrect one is : A number line with a closed circle on 6, shading to the right
Answer:
53.5
Step-by-step explanation:
c = the height of the first 3 boys.
c = 54 + 48.5 + 46
c = 148.5
Now you add a fourth boy. His height is h.
A(h)= (c + h)/d
d = the total number of boys which is 4.
The new average is 50.5
A = (c + h)/d
50.5 = (148.5 + h) / 4 Multiply both sides by 4
202 = 148.5 + h Now subtract 148.5 from both sides
202 - 148.5 = h
h = 53.5
