Answer: 50 hours
Step-by-step explanation:
Sarah:
50 x 17 = 850
Joey:
50 x 15 = 750
750 + 100 = 850
Answer:
7
Step-by-step explanation:
When you match the form
... ax² + bx + c = 0
to the equation
... 3x² + 5x + 7 = 0
it is reasonable to conclude that ...
... a = 3, b = 5, c = 7.
_____
The question presumes you are familiar with the form
... ax² +bx +c = 0
which is often used as the representation of a general quadratic equation. This lets us use a, b, and c instead of specific numbers, to talk about ways of factoring, graphing, or solving equations like this.
Answer:
<em>no solution</em>
Step-by-step explanation:
6x+ 3(-2x+4)=-12
6x-6x+12=-12
12 is not equal to -12.
Answer:
8/5
Step-by-step explanation:
Answer: YES
<u>Step-by-step explanation:</u>
Coterminal means they are located at the same place on the Unit Circle but are n-rotations clockwise or counterclockwise.
Start with 35° and continue to subtract 360° (which is one rotation) until you reach -685° or pass it. If you reach -685°, then it is coterminal. If you pass it, then it is not coterminal.
35° - 360° = -325°
-325° - 360° = -685°
So, -685° is 2 rotations counterclockwise to 35°, which means the two angles are coterminal to each other.
