First we add all the angles together
x + 2x - 20 + 2x + 10 = 5x - 10
Now, you should know that all the angles in a triangle add up to 180°
180 = 5x - 10
Move the 10 to the other side
190 = 5x
Divide both sides by 5
x = 38
So the angles sizes in ascending order are
38 , 46 , 86
Answer:
y=-6
Step-by-step explanation:
3y+7=-11
3y=-11-7
3y=-18
y=-18/3
y=-6
Answer:
16
Step-by-step explanation:
Given:
f(x)=3x+7 eq1
to find
f(3)
subtitute 3 in eq 1
<em>therefore,</em>
3*3+7=16
1a) The function has arrows on both ends and no place in the middle where it is not defined. Its domain is ...
All Reals
1b) The function gives no output values below -3, but it gives output values of -3 and all above that. Its range is ...
y ≥ -3
1c) For values of x less than -1, the function's output is 1. This matches g(x) and s(x). At x=0, the function's output is -3, which only matches g(x). The appropriate choice is ...
g(x)
2b) The function is only defined for 0 ≤ x < 8. This is its domain.
3) A definition might be ...
D. g(x)=-2IxI-3
The -3 is the vertical shift 2 units down
The -2 is multiplied outside of the x, so it’s a vertical stretch.
