Answer:
Step-by-step explanation:
The missing angle of the triangle is 180°-42°-60° = 78°.
x° = 180°-78° = 102°
To find the total increase, we will subtract -14 from 36.
36--14=50
(A double negative is a positive.)
50 is your final answer.
<u> -76 and 95 is the lowest and highest grade average in the class, respectively.</u>
Answer:
Step-by-step explanation:
LOL The graph doesn’t match the y intercept :)
Anyway
If we have point (0,-3) we have a quadratic of
y=ax^2+bx-3 we are given points (-1,0) and (2,0) so
a-b-3=0 and 4a+2b-3=0
4a+2b-3+2(a-b-3)=0
4a+2b-3+2a-2b-6=0
6a-9=0
6a=9
a=1.5, since a-b=3
1.5-b=3
b=-1.5
y=1.5x^2-1.5x-3
