Answer:
x = 0
Step-by-step explanation:
Given
9 + 5x = 9 + 2x ( subtract 2x from both sides )
9 + 3x = 9 ( subtract 9 from both sides )
3x = 0 ⇒ x = 0
Answer:
4
Step-by-step explanation:
in similarity the ratio of the similar sides is the same i.e
10/5 =8/x
2x=8
x= 4
Answer:
5.5, 9.5
Step-by-step explanation:
Let x and y be the numbers
x+y = 15
x-y = 4
Add the two equations together to eliminate y
x+y = 15
x-y = 4
------------------
2x = 19
Divide by 2
2x/2 =19/2
x = 9.5
Now find y
x+y = 15
9.5+y = 15
Subtract 9.5
x = 15-9.5
x =5.5

Hi there!
I will help you answering the questions, if you do not understand what I'm working about, you can ask me on comment section.
<h3>Number 1</h3>
First of all, we need to multiple the separated function.

So the right answer is <u>A</u>
━━━━━━━━━━━━━━━━━
<h3>Number 2</h3>
the graph has four zeros at :
After that we make them equal with 0, here is the thing:
x = -a is equal with x + a = 0
So we can conclude that :
- -4 → x + 4 = 0
- -2/3 → 3x + 2 = 0
- 0 → x = 0
- 9 → x - 9 = 0
Then we substitute them to a function :
x(x + 4)(3x + 2)(x - 9) = 0
3x⁴ - 13x³ - 118x² - 72x = 0
Then we looking on the option which one is equal with the answer above.
The right answer is <u>B</u>
