Maurinko [17]2 years ago
3 0

Answer:

The coordinates for the reflection of quadrilateral ABCD is..

A'(-7,2) ----> A'(-7,-2)

B'(-7,4) ----> B'(-7,-4)

C'(-4,6) ----> C'(-4,-6)

D'(-1,6) ----> D'(-1,-6)

Step-by-step explanation:

Since it's being reflected over the x-axis, the x remains the same and the y becomes a negative.

A line includes the points (-39,49) and (0,0). What is its equation in slope-intercept form?
malfutka [58]

Answer:

The equation in the slope-intercept form will be:

y=-\frac{49}{39}x+0

Step-by-step explanation:

Given the points

  • (-39,49)
  • (0,0)

Finding the slope between the points using the formula

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(-39,\:49\right),\:\left(x_2,\:y_2\right)=\left(0,\:0\right)

m=\frac{0-49}{0-\left(-39\right)}

m=-\frac{49}{39}

We know that the point-slope of the line equation is

y-y_1=m\left(x-x_1\right)

substituting m=-\frac{49}{39} and (-39,49)  in the equation

y-y_1=m\left(x-x_1\right)

y-49=\frac{-49}{39}\left(x-\left(-39\right)\right)

Now writing the equation in slope-intercept form

y=mx+b

where m is the slope and b is the y-intercept

y-49=\frac{-49}{39}\left(x-\left(-39\right)\right)

y-49=\frac{-49}{39}\left(x+39\right)

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}

y-49=-\frac{49}{39}\left(x+39\right)

\mathrm{Add\:}49\mathrm{\:to\:both\:sides}

y-49+49=-\frac{49}{39}\left(x+39\right)+49

y=-\frac{49}{39}x+0              ∵ y=mx+b

Where

m=-\frac{49}{39} and the y-intercept i.e. b=0

Therefore, the equation in the slope-intercept form will be:

y=-\frac{49}{39}x+0

Chau will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $50 and costs an addi
Svetach [21]

Answer:

175 Miles has to be driven to do the plans cost the same.

Step-by-step explanation:

Assume The Chau Drive Y miles .

We Have Given Two Plans ,

  • First Plan = 50$ + 0.19$ × Y
  • Second Plan = 57$ + 0.15$ × Y

Now,Put First Plan=Second Plan (When Both Plans Cost The Same)

50$ + 0.19$ × Y = 57$ + 0.15$ × Y

0.04$ × Y = 7  ⇔  Y = 175 Miles

If the purchase price for a house is $218,500, what is the monthly payment if you put 3.5% down for a 30 year loan with a
sashaice [31]

Answer:

218,500 - (3.5% down payment) =

210,852.50

30 years = 360 months

rate 6.5%

Use the loan payment formula (REALLY complex - see attached).

rate = 6.5/1,200 = 0.005416667

monthly payment = (rate + [rate / (((1 + rate)^months) -1)] * principal

monthly payment = (0.005416667 + [0.005416667 / (((1.005416667)^360)-1)] * principal

monthly payment = (0.005416667 + [0.005416667 / (((1.005416667)^360)-1)] * principal

monthly payment = 0.005416667 + [(0.005416667 / 6.9917988084 -1)] *  210,852.50

monthly payment = 0.005416667 + [(0.005416667 / 5.9917988084)] *  210,852.50

monthly payment = 0.005416667 + [(0.005416667 / 5.9917988084)] *  210,852.50

monthly payment = (0.005416667 + 0.0009040135) * 210,852.50

monthly payment = 0.0063206805 * 210,852.50

monthly payment = 1,332.73

Answer is a.

What is the value of y?<br><br> 39<br> 34<br> 16<br> 20 <br><br> one of those number is the answer
melomori [17]

Answer:

20

Step-by-step explanation:

we see here that angle RPN is 180 degrees. SPM is 90 degrees so

angle RPS + angle SPM + angle MPN = 180 degrees

(4y - 10) + 90 + y = 180

(4y - 10) + y = 90

5y - 10 = 90

5y = 100

y = 20
