jessy took out a loan of $16,500 over 5 years at 4.2% interest to purchase a new car. how much will she pay in interest on the loan. A)$693 B)$3,465 C)$34,650

Answers

Answer:

B

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.2%/100 = 0.042 per year,

then, solving our equation

I = 16500 × 0.042 × 5 = 3465

I = $ 3,465.00

The simple interest accumulated

on a principal of $ 16,500.00

at a rate of 4.2% per year

for 5 years is $ 3,465.00.

PLS HELP WILL GIVE BRAINLIEST!! Identify this set of lines as parallel, perpendicular, or neither.

Answers

Answer:

neither

Step-by-step explanation:

Answer:

neither

Step-by-step explanation:

parallel lines have the same slope

perpendicular lines have the opposite of the reciprocal of the slope of the other line

The slope of the first line is 3 and the slope of the second line is -3.

If the lines were parallel, the slopes would be the same, so 3 = -3 which is not true, so they aren't parallel.

If the lines were perpendicular, the slope of the second line would be the opposite reciprocal of 3, or -1/3. -1/3 does not equal 3, so these lines are not perpendicular

Three numbers A, B and C are in the ratio 7: 2: 4. The sum of the three numbers is 104. What is the number C?

Answers

Answer:

C = 32

Step-by-step explanation:

The numbers are in the ratio 7 : 2 : 4 = 7x : 2x : 4x ( x is a multiplier ) , then

7x + 2x + 4x = 104

13x = 104 ( divide both sides by 13 )

x = 8

Thus C = 4x = 4 × 8 = 32

Solve each system using substitution. Check your answer
x+3=y
3x+4y=7

Answers

Answer:

x = -5/7

y = 16/7

Step-by-step explanation:

3x + 4y = 7

3x + 4(x+3) = 7

3x + 4(x) + 4(3) = 7

3x + 4x + 12 = 7

7x + 12 = 7

7x + 12 - 12 = 7 - 12

7x = -5

7x ÷ 7 = -5 ÷ 7

x = -5/7

---------------------------------------

x + 3 = y

(-5/7) + 3 = y

16/7 = y

-----------------------------------------

3x + 4y = 7

3(-5/7) + 4(16/7) = 7

-15/7 + 64/7 = 7

7 = 7

The required value of the x and y by substitution method is -5/7 and 16/7 respectively.

Given,
System of equation
x+3=y
3x+4y=7

To solve using the substitution method.

What is the equation?

The equation is the values of two functions  that are equal.

What are functions?

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

x + 3 = y - - - - -(1)
3x + 4y = 7 - - - -(2)

from equation 1 substitute y in equation 2

3x + 4( x +3 ) = 7
3x + 4x + 12 = 7
7x = 7 - 12
7x = -5
x = -5/7
put this x on equation 1
-5/7 +3 = y
y = 16/7

Thus the required value of the x and y by substitution is -5/7 and 16/7 respectively.

y= -3x + 1 and y= x - 3

Answers

Answer:

x= 1

y= -2

Step-by-step explanation:

equation (1): y= -3x+1

equation (2): y=x-3

solve the system of equations by substitution:

step1: sub ( x-3 ) for y in equation 1:

y = -3x+1

x-3 = -3x+1

step2: simplify the equation to get x:

(add 3 for both sides)

x = -3x+4

(add 3x for both sides)

4x = 4

(divide 4 from both sides)

x = 1

step3: sub the value of x (x=1) in equation 2:

y = x-3

y = 1-3

step4: solve the equation to get y:

y = -2
