F ( x ) = 4 x² + 8 x + 7
a = 4, b = 8
The axis formula is:
x = - b / 2 a
x = - 8 / (2*4) = - 8 / 8 = -1
Answer:
The axis of the graph of the function is x = - 1.
Answer:
Yes
Step-by-step explanation:
As long as the slopes of these two lines are not the same, they will intersect.
Given two points on a line, we can find the slope by taking the difference in the y coordinates and dividing it by the difference in the x coordinates.
Slope of 1st line: 
Slope of 2nd line: 
The slopes are not equal, therefore the lines intersect.
Answer:
B)120º
Step-by-step explanation:
70+50=x
120=x
Answer:
X>-9
Step-by-step explanation:
Distribute
-5x-35<10
add 35 on both sides
-5x<45
Divide -5 on both sides and flip the sign since your dividing by a NEGATIVE number
x>-9
You need to find the GCF (greatest common factor) of 45 and 90, which is 45.
45 times ? gets you 45
? would be 1
45 times 1 equals 45.
45 times ? gets you 90
? would be 2
45 times 2 equals 90
45(1+2) = 45+90 = 135
