a.
Express his down payment algebraically.
b. How many monthly payments must Mike make?
C.
Write expressions for the total amount of the monthly payments and the finance charge.

Answers

Using the appropriate interest relation, the solution to the problems posed are :

Down payment = 0.05k 144 monthly payments Total monthly payment made = 144g

Down payment :

5% of total cost Total cost = k

5% × k = 0.05k

B.)

Number of monthly payments :

Number of months per year = 12

Number of years = 12

Number of monthly payments = 12 × 12 = 144

C.)

Total charge :

Monthly payment = $g

Number of monthly payments × amount paid

g × 144 = 144g

Equation a line into slope-intercept form simplifying fractions 5x+6y=42?

Answers

Answer:

5x+6y = 42

Step-by-step explanation:

solve for y

6y = -5x + 42

y = (-5/6)x +42/6

y =(-5/6)x + 7 where -5/6=slope and 7=y intercept

Let’s start from 5x+6y=42.

We want it to get down to y= something. Since we are trying to convert it to y=mx+b form!

5x+6y=42

Subtract 5x on both sides.

6y=-5x+42

Divide both sides by 6.

y=-5/6x+7.

And that’s the equation in slope intercept form!

The sum of three numbers is 164. The second number is 3 more than twice the first number, and the third number is four times the first number. What are the three numbers

Answers

Answer:

23, 49, and 92

Step-by-step explanation:

three numbers x, y, z

x+y+z=164

y=2x+3

z=4x

we have three equations and two of them are in terms of x so we can solve for x first by plugging in the two equations to our first equation

x+2x+3+4x=164

7x+3=164

7x=161

x=23

then find y

y=2(23)+3=46+3=49

then find z

z=4(23)=92

Answers

Answer:

y=5/2x+13.5

Step-by-step explanation:

5x-2y=10

-2y=-5x+10

y= 5/2x-5

y-6=5/2(x+3)

y-6=5/2x+ 7.5

y=5/2x+13.5

Answer:

Step-by-step explanation:

First you must isolate y in the given equation

5x - 2y = 10 Subtract 5x from both sides

-2y = -5x + 10 Divide both sides by - 2

y = -5/-2 x + 10 / -2

y = 2.5 x - 5 The new equation has a slope of 2.5

x = - 2

y = 6

y = 2.5x + b

6 = 2.5*-2 + b

6 = -5 + b Add 5 to both sides

6+ 5 = b

b = 11

Answer: y = 2.5x + 11
