Answer:
Step-by-step explanation:
work backwards to find the factors from the roots then multiply the factors together. y= x² - 24x + 140
Answer:
x=80
Step-by-step explanation:
The angle of a line is 180*.
The equation would be (x+20)+x=180
Subtract 20 from both sides: 2x=160
Divide by 2: x=80
That's your answer!
I hope this helps!
Answer: ∠B=70°
Step-by-step explanation:
It is shown in the diagram that ∠A and ∠B is vertical angles.
- Vertical angle theorem: opposite angles are congruent.
<u>Solve:</u>
∠A=∠B
8x+6=4x+38
4x=32
x=8
<h2>∠B=4x+38=4(8)+38=32+38=70°</h2>
On week 1, we started with a deposit of $200. Every week from that point on, we place a deposit of $55.
We know y is total amount of money (deposits) in the bank account.
We also know x represents the number of weeks.
On week 1, we would have $200 in the back account.
On week 2, we would have $200 + $55 or $255 in the bank account.
So, we could build an expression of 55(x - 1) + 200 which is equal to y.
So, y = 55(x - 1) + 200 is the answer.
