31) there are 12. The distance between them is 10-4=6. This is halfway around so there are 12 (think of a clock face, 4 is opposite 10 and there are 12 numbers.)
Answer:
600, 150
Step-by-step explanation:
Kyle is x
ken is y
x = 4y
x+y = 750
replace x with 4y
4y + y = 750
5y = 750
y = 150
so ken earned 150
x + 150 = 750
x = 600
so Kyle earned 600
Answer:
- y = 3(x -3)^2 +1
- y = 3x^2 -18x +28
Step-by-step explanation:
For vertex (h, k) and vertical scale factor "a", the vertex form of the equation of a parabola is ...
y = a(x -h)^2 +k
For (h, k) = (3, 1) and a = 3, the equation in vertex form is ...
y = 3(x -3)^2 +1
__
Expanding this gives the equation in standard form.
y = 3(x^2 -6x +9) +1
y = 3x^2 -18x +28

Step-by-step explanation:
Answer: w = 110° x = 83° y = 87° z = 97°
<u>Step-by-step explanation:</u>
∠(x - 13) and ∠w form a linear pair so their sum is equal to 180°
x - 13 + w = 180 → w = -x + 193
∠(x + 10) and ∠y form a linear pair so their sum is equal to 180°
x + 10 + y = 180 → y = -x + 170
∠x and ∠z form a linear pair so their sum is equal to 180°
x + z = 180 → z = 180 - x
∠x and ∠y and ∠w are the angles of a triangle so their sum equals 180°
x + y + w = 180
x + (-x + 170) + (-x + 193) = 180 Substitution
-x + 263 = 180 Add Like Terms
-x = -83 Subtracted 263 from both sides
x = 83 Divided both sides by -1
w = -x + 193 y = -x + 170 z = 180 - x
w = -83 + 193 y = -83 + 170 z = 180 - 83
w = 110 y = 87 z = 97
