4x + 3y = 26
x = 3/2y + 2

solving for y:

4 (3/2y + 2) + 3y = 26
6y + 8 + 3y = 26
9y + 8 =26
9y = 18
y = 2

solving for x:
x = 3/2(2) + 2
x = 3 + 2
x = 5

done.

Use the elimination method to solve the system of equations. Choose the
MatroZZZ [7]

Answer:

C

Step-by-step explanation:

7x + 3y = 30 (equation 1)

-2x + 3y = 3 (equation 2)

9x = 27 (subtract the two equations to eliminate y)

x = 3 (divide by 9)

7 * 3 + 3y = 30 (Substitute x = 3 into equation 1, it doesn't matter which equation you substitute into)

21 + 3y = 30 (7 * 3 = 21)

3y = 9 (Subtract 21)

y = 3 (divide by 3)

Answer is (3, 3)

To pay for a $23,600 motorcycle, Raphael made a down payment of $3300 and took out a loan for the rest .on the loan, he paid mon
Zolol [24]

Answer:

-Total amount Rafael ended up paying for the motorcycle: $25,186.2

-Interest: $1,586.2

Step-by-step explanation:

You can find the total amount Rafael ended up paying by adding up the down payment plus the result of multiplying the monthly payment for the number of months he paid:

Total payment=3,300+(364,77*60)

Total payment=3,300+21,886.2

Total payment=25,186.2

Now, to calculate the amount of interest that Raphael paid on the loan, you should subtract the price of the motorcycle from the total amount Raphael paid:

Interest=$25,186.2-$23,600

Interest=$1,586.2

Samantha threw and apple out of the window fr the tenth floor of her apartment building. The equation y= -16t^2 +120 can be used
prohojiy [21]
Answer:
time taken = 2.74 seconds

Explanation:
We are given that:
y = -16t² + 120 models the situation where:
y is the floor number
t is the time taken for the apple to hit the ground

We are also given that the floor number (y) is 10. Therefore, all we have to do is substitute with y in the above equation and solve for the time t as follows:
y = -16t² + 120
10 = -16t² + 120
120 - 10 = 16t² 
110 = 16t²
t² = 110/16
t = ±√6.875
either t = 2.74 seconds ..........> accepted
or t = -2.74 seconds .........> rejected as time cannot be in negative

Hope this helps :)
