Hey!
The first step to solving this equation would be to subtract 5 from both sides of the equation.
<em>Original Equation :</em>

- 8x + 16 = 5
<em>New Equation {Added Subtract 5 to Both Sides} :</em>

- 8x + 16 - 5 = 5 - 5
Now we solve our new equation.
<em>Old Equation :</em>

- 8x + 16 - 5 = 5 - 5
<em>Solution {Old Equation Solved} :</em>

- 8x + 11 = 0
The next step would be to solve with the quadratic formula.
<em>Quadratic Equation ( 1 ) :</em>

<em>Quadratic Equation ( 1 ) {Solved} :</em>
4 +

<em>Quadratic Equation ( 2 ) :</em>

<em>Quadratic Equation ( 2 ) {Solved} :</em>
4 -

<em>So, our final solutions for the equation

- 8x + 16 = 5 are...</em>
x = 4 + 
<em>and </em>
x = 4 - 
Hope this helps!

Answer:
I think its A
Step-by-step explanation:
a. The equation of the trend line is c=5x+100.
b. The equation of the trend line is c=-5x+100.
c. As the hours of training increase by 5, the greeting cards made increases by 25.
d. As the hours of training increase by 5, the greeting cards made decreases by 25.
For the first one, find a number in which, when factored, will give you 4.
x² + 4x + 4
x 2
x 2
(x + 2)(x+ 2)
4 is your best answer
2. x² - 10x + ____
Same for this question. Find a number that, when factored, will give you -10
-100
x² - 10x + 25
x - 5
x -5
(x - 5)(x - 5)
25 is your answer
hope this helps
Answer:: the equation is 7m + 19
Step-by-step explanation:
Answer:
126
Step-by-step explanation:
a = 22
d = 22- 20 = -2
n = 9
Sn = 0.5n(2a +d(n-1))
=0.5 * 9 (2 *22 +-2(9-1))
= 126
