69.92 when you add them all up and divide it you get 69.92
Answer:
$144
Step-by-step explanation:
since Jessie earns $12 an hour, if he works 12 hours, multiply the amount per hour by the amount of hours worked.
12 x 12 = 144
Therefore, Jessie will earn $144 in 12 hours
For x intercepts, plug in 0 for y.
0 = (x^2) - 2x - 35
*factoring* = (x-7)(x+5)
x intercepts = 7,-5
As for the vertex, you can use the equation -b/2a for the x-coordinate of the vertex
so,
x = -b/2a = -(-2)/2 = 1
then just find the y value by plugging it back in to the equation.
y = ((1)^2) - 2(1) - 35
= -36
so, vertex is at (1,-36)
If you understand what is linear pair, you can see the same in triangle also. A linear pair is a pair of adjacent, supplementary angles. Adjacentmeans next to each other, and supplementary means that the measures of the two angles add up to equal 180 degrees.
