Write the equation in intercept form: 4x+ 9y= -36

1 answer:

6 0

Intercept form
the only one that is intercept form is slope-intercept form which is
y=mx+b
m=slope
b=slope
so solve for y
4x+9y=-36
subtract 4x from both sides
9y=-4x-36
divide both sides by 9
y=-4/9x-4

If you deposit $10,000 in a bank account that pays 10% interest annually, how much will be in your account after 5 years?

Luba_88 [7]

Interest formula: A=P(1 + r)^t
A = 10000(1 + 0.1)^5
A = 10000(1.01)^5
A = 10000(1.0510100501)
A = $10,510.10

Solve the system: 2x+6y=36 x+4y=20

Assoli18 [71]

Let's solve this problem step-by-step

Let's set:

2x + 6y = 36 -- equation 1

x + 4y = 20 -- equation 2

(equation 2) * 2

2x + 8y = 40 -- equation 3

(equation 3) - (equation 1)

2y = 4

y = 2 -- equation 4

Plug (equation 4)'s value of y into (equation 2)

x + 4(2) = 20

x = 20 - 8

x = 12

Thus x = 12 and y = 2

Let's check, by substituting these values

$2x + 6y = 36\\2(12)+6(2) = 36\\24+12=36\\36=36\\\\x+4y=20\\12+4(2)=20\\12+8=20\\20=20$

Answer: x = 12 and y = 2

Hope that helps!

Ryan took out a 66 month loan to pay for a 28500 car.if he paid 33829.50,in total at the end of the loan,find the interest rate

professor190 [17]

9514 1404 393

Answer:

3.4%

Step-by-step explanation:

The total amount due is ...

A = P(1 +rt/12) . . . . . principal P, annual rate r, t months

33829.50 = 28500(1 +66/12r)

1.187 = 1 +5.5r . . . . . divide by 28500, simplify

0.185/5.5 = r = 0.034 = 3.4%

The interest rate on the loan is 3.4%.
