Answer:
x = 2
Step-by-step explanation:
You can make a ratio out of this!
2 / x = (x+1) / 3
1. Cross multiply^
2. 2 * 3 = x (x+1)
3. 6 = x^2 + x
3. x^2 + x - 6
4. Factor^
5. (x-2)(x+3)
6. x - 2 = 0 turns into x = 2
7. x + 3 = 0 turns into x = -3
8. There's not way to measure -3 yet, so you are left with x = 2

The smallest angle in a triangle measures 9 degrees less than the middle angle. The largest angle is 26 degrees more than 3 times the measure of the smallest angle.
Answers
Answer:
Step-by-step explanation:
A+B+C = 180°
A ≤ B ≤ C
B = A+9
C = 3A+26
A+B+C = A + (A+9) + (3A+26) = 5A + 35° = 180°
5A = 145°
A = 29°
B = A+9 = 38°
C = 3A+26 = 113°

Then, represent each transaction on a number line. What is the unknown quantity in each case? 1. In the first week he spent $16 on lunches. How much was in his account then? 2. Then he deposited some more money and his account balance was $28. How much did he deposit? 3. Then he spent $34 on lunches the next week. How much was in his account then? 4. Then he deposited enough money to pay off his debt to the cafeteria, How much did he deposit? 5. Explain why it makes sense to use a negative number to represent Kiran's account balance when he owes money.

Answer: 8, 20, -6, 6
Step-by-step explanation:
1. you need to to subtract 24-16=8
2. then you subtract 28-8=20
3. Then you subtract 28-34= -6
4. At the end you just put in 6!

Answer:
Because it means that person Deposited that much that they didn't have so meaning when they add new money the negative number something of the amount will be taken away.
An Example is a person has in their bank account 20 dollars. They Spent 25 dollars so then means they owe the bank 5 dollars so it's gonna be -5.

Line AB and line BC form a right angle at point B. If A = (-3, -1) and B + (4, 4), what is the equation of line BC?
A.) x + 3y = 16
B.) 2x + y = 12
C.) -7x - 5y = -48
D.) 7x - 5y = 48
Answers
Answer:
C.) -7x - 5y = -48
Step-by-step explanation:
slope AB = (y2 - y1)/(x2-x1)
= {4-(-1)}/{4-(-3)} = 4+1/4+3 = 5/7
slope of BC = -1 ÷ 5/7 = -1 × 7/5 = -7/5
taking -7x - 5y = -48
-5y = 7x -48
y = 7x/-5 - 48
y = -7/5x -48

Answer:
y - 3 = 2(x + 1)
Step-by-step explanation:
First, use rise over run to find the slope
(y2 - y1) / (x2 - x1)
(3 + 7) / (-1 + 6)
10 / 5
= 2
Now, plug in the slope and a point into the point slope formula:
y - y1 = m(x - x1)
y - 3 = 2(x + 1)
So, the equation in point slope form is y - 3 = 2(x + 1)
