Y+4x =7
Or y = -4x + 7
On comparing with point slope form
y = mx+c
We get m = -4 = slope of given line
As the required line is parallel to given line its slope is equal to -4
30 + (40 × 3) = 150
60 + (30 × 3) = 150
in three months the total cost would he the same.
While setting up a fireworks
display, you have a tool at the top of the
building and need to drop it
to a coworker below. Given the equation:
h(t) = -16t^2 + h0
h = 84 feet
it will take the tool to fall
to the ground 2.29 time unit
-84 = -16t^2 – 0
<span>t = 2.29 time unit</span>
Answer:
147˚, 33˚
Step-by-step explanation:
supplementary angles means those angles add up to 180˚
so A+B = 180
substitute A and B with the values given.
(4a+7) + (a-2) = 180
combine like terms
5a + 5 = 180
5a = 175
a = 35
Now that we have a, substitute in the actual value of a into the expressions for each angle.
for <A: 4(35) + 7 = 147˚
for <B: 35 - 2 = 33˚
