Answer:
x = 1
Step-by-step explanation:
For a quadratic function 
, the axis of symmetry is
.
This comes from using part of the Quadratic Formula for finding zeros of the function:
See the -b/(2a) in the first term? That's the x-coordinate of the vertex (turning point) of the parabolic graph of the function. The axis of symmetry goes through the vertex.
Answer:
90, 91 and 92
Step-by-step explanation:
Given
Consecutive integers = 273
Required
Find the integers
The question seem to be incomplete. However, I'll assume we're dealing with sum.
Let the smallest integer be y.
So,
y + y + 1 + y + 2 = 273
Collect like terms.
y + y + y = 273 - 2 - 1
3y = 270
Divide both sides by 3
y = 90
Hence, the integers are 90, 91 and 92
30 hours. Just multiply 10 by 15 to get 150 and then 2 times 15 is 30.
1) the slope for the points (-4,7) and (-7,-15) is -2.
2) The slope for the function b is D) 2/11
Hope this helps!
Answer:
3x + 22 = 82
Step-by-step explanation:
3x + 22 = 82
-22 = -22
3x= 60
3 = 3
X =20
