Answer:
The number is -37.
Step-by-step explanation:
2(x - 8) = 3(x + 7)
2x - 16 = 3x + 21
x = -37
The y intercept is -2. There is two x- intercepts because it is a parabola so,
x=-1
x=2
The axis of symmetry is where it splits evenly so, we can conclude it is less than 1 and bigger than 0. I hope this makes sense.
Answer:(-4,0)
Step-by-step explanation:
Given
Point A (6,-4)
Reflection of Point A about line y=-2 is
A' (6,0)
If any Point is reflected about any line y=constant then its x coordinate remains same
Now reflection of Point A' about x=1 is
A'' (-4,0)
If any point is reflected about line x=constant then its y coordinate remains same
Okay, so on number one I have no idea. I keep getting 20 because 14 - (-3)2 = 14- (-6) which is really 14 + 6=20.
Number 2 is r+15=61
Number 3 I didn't get any of those answers because you have to solve what is in the parenthesis first so3*5= 15+1=16 then you multiply that by two giving you 16*2=32 and 42-32=10
Answer:
B.
Step-by-step explanation:
<2 and <3 are vertically opposite angles and are also congruent. Both the angles are hence called vertical angles.
