Answer: 6.2
Step-by-step explanation:
Answer: 0.76, -0.76
Step-by-step explanation:
Answer:
x= 28
Step-by-step explanation:
The angles both sum up to 180°. So, the equation would be: 39+(5x+1)= 180.
Step 1- Add common numbers.
(39+1)+5x= 180
40+5x= 180
Step 2- Subtract 40 to both sides.
40+5x= 180
-40 -40
5x= 140
Step 3- Divide both sides by 5.
<u>5x</u>= <u>140</u>
5 5
x= 28
The parabola goes down(makes a sad face) because it is negative. The answer is 0,0
