Answer:

$2322.59

Step-by-step explanation:

Given

mortgage amount=$470,000

Interest rate annually=4.6%

Time=30 years

Monthly payments=?

Formula to apply

M=\frac{P(1+r)^n*r}{(1+r)^n-1}

where

M=monthly payment for the mortgage

P=Principal amount =$470,000

i=rate per month=4.6÷12=0.3833%

n=30×12=360

Applying the formula

M=\frac{P(1+r)^n*r}{(1+r)^n-1} \\\\\\M=\frac{470000(1+0.004)^{360}*0.004 }{(1+0.004)^{360} -1} \\\\\\M=\frac{7452.235}{3.209} =2322.59

Write an equation in slope intercept form for <br> the given slope.<br> (5,9).(6,8)
vovangra [49]

<u>Answer: </u>

The equation in slope intercept form for (5,9) and (6,8) is y = 3x-10

<u>Solution: </u>

Given that (5,9) and (6,8)

Here, x_{1}=5 ; y_{1}=5 ; x_{2}=6 ; y_{2}=8

We know the slope of an equation is given by y = mx+c

To find the value of m, we use the below given formula

\mathrm{m}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Substituting the values we get,

\mathrm{m}=\frac{8-5}{6-5}

m = \frac{3}{1}

m = 3

Putting the value of m in the slope intercept form we get,

y = 3x+c

To find the value of c, we substitute the value of x and y from any two given point. Let’s take x = 5 and y = 5

5 = 3(5) + c

5 = 15 +c

5-15 = c

c = -10

Therefore the slope intercept equation becomes y = 3x -10

Solve the following equation for x. Round the answer to the nearest hundredth.
Serhud [2]

Hence, option D 4: x=-1.34 is correct

Further explanation:

In order to solve an equation in one varible we have to isolate the variable on one side of the equations

Given equation is:

-1.2x=2(x+2.15)\\Simplifying\\-1.2x=2x+4.3\\Subtracting\ 2x\ from\ both\ sides\\-1.2x-2x=2x+4.3-2x\\-3.2x=4.3\\Dividing\ both\ sides\ by\ -3.2\\\frac{-3.2x}{-3.2}=\frac{4.3}{-3.2}\\x=-1.34375\\Rounding\ off\ to\ nearest\ 100th\\x=-1.34

Hence, option D: x=-1.34 is correct
