Choose two coordinates. I will choose the ones you chose, (-2, -3) and (0, 1).
Find the slope first using the slope equation: [tex]\frac{y2-y1}{x2-x1}[/tex]
y2 is 1, y1 is -3, x2 is 0, and x1 is -2.
[tex]\frac{1-(-3)}{0-(-2)}[/tex]
[tex]\frac{1+3}{0+2}[/tex]
[tex]\frac{4}{2}[/tex]
m = [tex]2[/tex]
The slope is 2.
Now that we found out the slope, we can start to assemble our equation. The m in the equation y = mx + b stands for the slope.
Now the equation is: y = 2x + b.
We need to figure out the y-intercept next. The b in the equation stands for the y-intercept. Choose one coordinate. I will chose (0, 1). x = 0 and y = 1. Substitute 0 in for x and 1 into y.
y = 2x + b
1 = 2(0) + b
1 = 0 + b
1 = b
Now we know what b is. Plug in 1 for b in the equation.
y = 2x + 1
I hope this helps! Let me know if I got something wrong and I'll fix it.

$2.05 is the amount paid for mileage.
This is 205 cents for mileage
at 71 cents per mile. Divide
205 by 71 to get the miles driven.

write 34 as a product of its prime factors. PLEASE HELP I NEED TO TURN IT IN IN % MINUTES
Answers
Answer: Down below
Step-by-step explanation: First of all, as 34 is an even number, so it must be divisible by smallest prime 2.
Thus, 2 must be a factor of 34.
Now, look for number obtained on dividing 34 by 2 i.e.
34÷2=17.
So, 17 is our new number.
Now, look for factors/divisors of 17, which are precisely 1 and 17 i.e. 17 is itself a prime.
This implies only factors possible for 34 are 2 and 17.
Thus ,34 can be written as product of prime numbers 2 and 17 as 34=2×17.
Key idea. Given any number, divide it by smallest divisible prime and look for the number obtained on division.
Now, repeat the process for the number obtained.
If no division by a smaller prime than that number is possible, then our number is itself a prime.

The trapezoid below has been enlarged by a scale of 1.5. What is the area of the enlarged trapezoid?
Answers
Answer:
New area by scale of 1.5 = 81 in²
Step-by-step explanation:
Given:
Current area = 36 in²
Find:
New area by scale of 1.5
Computation:
New area by scale of 1.5 = Current area x (scale factor)²
New area by scale of 1.5 = 36 x (1.5)²
New area by scale of 1.5 = 36 x (2.25)
New area by scale of 1.5 = 81 in²
Answer:
B.
Step-by-step explanation:
We have been given that the trapezoid shown in the attachment has been enlarged by a scale of 1.5.
We are asked to find the area of the enlarged trapezoid. The area of the original trapezoid is 36 square inches.
Since each side of the trapezoid is enlarged 1.5 times, so the area of new trapezoid would be 2.25 times greater than area of original trapezoid.
The area would be 2.25 times greater because area is product of sum of lengths of parallel sides and height.
Therefore, the area of the enlarged trapezoid would be and option B is the correct choice.
If x = 45, y = 63, and the measure of AC = 4 units, what is the difference in length between segments AB and AD? Round your answer to the nearest hundredth.
0.74 units
1.17 units
1.64 units
2.14 units
Answers
Answer:
1.17
Step-by-step explanation:
(MUCH BETTER!)
From the definition of the sin of an angle, you know:
sin(45°) = AC/AB = 4/AB ⇒ AB = 4/sin(45°) ≈ 5.6569
sin(63°) = AC/AD = 4/AD ⇒ AD = 4/sin(63°) ≈ 4.4893
Then the difference AB-AD is:
AB -AD = 5.6569 -4.4893 = 1.1676
AB -AD ≈ 1.17 units

Your cousin borrows $1125 to repair her car. The simple annual interest rate is 10%. She makes equal monthly payments of $25. How many years will it take to pay off the loan?
Answers
Answer:
26 months i believe is correct :)
Step-by-step explanation:
The number of years it will take to pay off the loan will be 4.125 years based on simple interest.
What is simple interest?Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.
As per the given,
Total loan = $1125
Rate of interest R = 10%
Monthly payment = $25
Yearly payment = 25 x 12 =$300
Suppose it takes T years,
Total amount A = principle P + interest
A = 1125 + 10% of 1125
A = 1125 + 0.10 x 1125
A = $1237.5
The number of years it will take will be as follows,
Total amount / yearly payment
⇒ 1237.5/300
⇒ 4.125 years.
Hence"The number of years it will take to pay off the loan will be 4.125 years based on simple interest".
