Answer:
x = 4.1 & x = −4.1
Step-by-step explanation:
x = ±√17
x = √17, −√17
x = 4.1 & x = −4.1

Answer:
- equation: 1/2(s +8) = 20
- Mark began with 32 boxes
Step-by-step explanation:
Let s represent the number Mark started with. After buying 8 more, he then had s+8. After the fire, he had ...
(1/2)(s +8) = 20
This equation can be solved by multiplying by 2, then subtracting 8.
s +8 = 40
s = 32
Mark began with 32 boxes.
Answer:
WR = 16
Step-by-step explanation:
The centroid M is the point where the 3 medians intersect
The median is a segment that goes from one of the triangle's vertices to the midpoint of the opposite side.
WY is a median of the triangle , then
WY = YR = 8
WR = wy + yr = 8 + 8 = 16
Answer:
Then the solution is (-1/4, 3)
Step-by-step explanation:
Start by eliminating the fractional coefficient 1/4: multiply all 3 terms in the second equation by 4. This results in equation (b), below:
4x - 3y = -10 (a)
4x = y -4 (b)
Substitute y - 4 for 4x in equation (a):
y - 4 - 3y = -10
Combining like terms, we get -2y = -10 + 4, or -2y = -6, or y = 3.
Since x = (1/4)y - 1, if y = 3, then x = (1/4)(3) - 1, or x = 3/4 - 1, or x = -1/4
Then the solution is (-1/4, 3)
