Answer is -10.
x-intercept, y=0, substitute for y in the equation. you will have -2x+5(0)=20
-2x =20
x =20/-2
x=-10

Step-by-step explanation:
How to write numbers in standard form:
Write the first number 8.
Add a decimal point after it: 8.
Now count the number of digits after 8. There are 13 digits.
So, in standard form: 81 900 000 000 000 is 8.19 × 10¹³
Answer:
The answer is<u> 2)a=−2</u>
7x-2x+15=10
5x+15 = 10
- 15 (on both sides, cancels out on the left side)
5x= -5
÷5 (on both sides, cancels out on the left)
x = -1
I hope that helped! ☺♥
So in the table, you have to insert the values of a, and then what that expression would equal when a is that value. I have redrawn the table and filled it in for you, but let me know if you would like an explanation for each answer :)
