Answer:
uh thanks for the points
Step-by-step explanation:
M = -2
In perpendicular lines, the slopes are opposite reciprocal. This means you flip the sign (from + to - or from - to +) and flip the numerator and denominator.
So 1/2 becomes negative, and 2/1 = 2
So the slope is -2
Because Sam is 19, and is 6 years older than Mia 19-6=13 so Mia is 13. Mia is also 3 years younger than Alice so Alice’s age= 13+3=16 so Alice is 16
Answer:
10
in
Step-by-step explanation:
Use the volume formula for a rectangular prism, V = lwh
Plug in the volume, length, and width, then solve for the height
V = lwh
157 = (5)(3)(h)
157 = 15h
10 = h
So, the box's height is 10 in
In the second equation:
Subtract 8x from both sides.
2z = 22 - 8x
Divide 2 on both sides.
z = 11 - 4x
Plug this into the first equation.
-66 - 2(11 - 4x) = -196
-66 - 22 + 8x = -196
Combine like terms.
-88 + 8x = -196
Add 88 to both sides.
8x = -108
Divide 8 on both sides.
x = -13.5
Put this into the second equation.
8(-13.5) + 2z = 22
-108 + 2z = 22
Add 108 to both sides.
2z = 130
Divide 2 on both sides.
z = 65
and
x = -13.5
Hope this helps!
