Answer:
Step-by-step explanation:
a + d + m + r = 16
a = d + 3......d = a - 3
a = m + 2.......m = a - 2
m = r + 1.......r = m - 1.......r = (a - 2) - 1......r = a - 3
a + (a - 3) + (a - 2) + (a - 3) = 16
4a - 8 = 16
4a = 16 + 8
4a = 24
a = 24/4
a = 6 <==== andrew scored 6
d = a - 3.....d = 6 - 3.....d = 3 <=== danielle scored 3
m = a - 2......m = 6 - 2.....m = 4 <==== mel scored 4
r = a - 3......r = 6 - 3 ......r = 3.......renee scored 3
Answer:
2
Step-by-step explanation:
On a number line, v would be all the numbers to the left of -3 (for example, |-4|=4 which is greater than 3) and all the values to the right of positive 3. Since it can't equal 3, v=-3 and v=3 are not included on the number line.
Answer:
y = 4x + 8
Step-by-step explanation:
1) Find slope:
y2-y1/x2-x1
12-8/1-0 = 4/1 = 4
Slope = 4
2) Plug in a point in point-slope form
y-y1=m(x-x1)
y-8=4(x-0) =
y-8=4x-0 -> add 8 to both sides
y=4x+8
-3
-3 2/8 is the same as -3 1/4
-3 1/4 + 1/4 = -3
