What is the slope of the line do the point for me to?

Mathematics
1 answer:
larisa86 [58]3 years ago

Answer:

Step-by-step explanation:

we can see that the line goes thru the point (-1,2) and (4,-2) now to find slope we just find change in y over change in x

more visually:

(y1-y2)/(x1-x2)

so for the point (-1,2) let’s say

-1 = x1

and

2 = y1

and for the point (4,-2) let’s say

4 = x2

and

-2 = y2

to find slope we plug in the values to our slope equation and we get this:

(2-(-2))/( -1-4)

(2+2)/-5

4/-5

so slope is -4/5

because to get from (-1,2) to (-4,-2) you have to move down 4 and to the right 5

Not sure if this is correct but:

Step-by-step explanation: P = 2000

                                             R = 5% = 0.05

                                             n = 4

                                      y = 2000 ( 1 + \frac{0.05}{4}) ^{4t} = 2000 ( 1.0125 )

                                       Substitute values in the compound interest formula:

                                        y = P ( 1 + \frac{r}{n})^{nt} .

Hope this helps..

If M is the midpoint of PQ and X is the midpoint of PM then PX = a PQ Which statement is True? a is equal to 1 a is equal to 1/2
garik1379 [7]

Answer:

D. a is equal to  \frac{1}{4}

Step-by-step explanation:

Let us assume that segment PQ is 8 units, so that its midpoint M is at 4 units to both P and Q.

Given that X is the midpoint of PM, this implies that X is at 2 units to both P and M.

Then;

PX = aPQ

⇒   = a x 8

      = 8a

Therefore, a must be equal to \frac{1}{4}, so that;

PX = 8a

     = 8 x  \frac{1}{4}

     = 2 units

Thus, a is equal to  \frac{1}{4} is the correct option.

Amy wants to buy a new set of paints. At store A, the cost is $22.00, and she has a coupon for 20% off. At store B, the cost is
Afina-wow [57]

Answer:

Store B

Step-by-step explanation:

Store A

20% is just 1/5 in percent form

22.00= 22*1/5 = 22/5 = 4.40

22.00-4.40=17.6

Store B

22.50-5=17.5

Now you can see that 17.5 is less than 17.6 by 0.1

Not sure. Please explain the steps.
stiv31 [10]

Answer:

answer C

Step-by-step explanation:

hello

because this is not allowed to divide by 0 I would take x real different from 0 and from -5/4

\dfrac{8x^3-10x^2-25x}{4x^2+5x}=\dfrac{x(8x^2-10x-25)}{x(4x+5)}=\\\dfrac{8x^2-10x-25}{4x+5}=\dfrac{(4x+5)(2x-5)}{4x+5}=2x-5

indeed if we develop

(4x+5)(2x-5)=8x^2-20x+10x-25=8x^2-10x-25

hope this helps
