Answer:
The point (0,-2) is the solution to the problem. Substitue 0 into x, the answer is -2 which matches f(x), or y value.
Step-by-step explanation:
Answer:
x= - 30
Step-by-step explanation:
x-9=0.7x+0.6
x-9=1.3x
x-9-1.3x=0
x-1.3x=9
x(1-1.3)=9
-0.3x=9
x= - 9/0.3
x= - 30
-3.
It's the same as normal division unless they have different signs, then it's negative.
A right triangle has 1 90 degree angle and the interior angles must add to 180.
3(x+8)+x+90=180
3x+24+x+90=180
4x+114=180
4x=66
x= 16.5
Plug this value in to find the last angle
16.5+90+x=180
106.5+x=180
x=73.5
Final answer: 73.5 degrees and 16.5 degrees
