What equation is graphed in this figure? y−4=−13(x+2) y−3=13(x+1) y+2=−3(x−1) y−5=3(x−1) Number graph ranging from negative four

omeli [17]

Answer: The correct option is 3.

Explanation:

It is given that the line passes through (-1,4) and (1,-2).

The slope of the line is,

$m=\frac{y_2-y_1}{x_2-x_1}$

The slope of the given line is,

$m=\frac{-2-4}{1-(-1)} =\frac{-6}{2}=-3$

The point slope form of a line is,

$y-y_1=m(x-x_1)$

Where, m is the slope.

Since slope is -3 and point is (-1,4), then the equation of line is,

$y-4=-3(x+1)$

Since slope is -3 and point is (1,-2), then the equation of line is,

$y+2=-3(x-1)$

Therefore, the correct option is 3.

If the probability of getting a particular result in a experiment is 75.3% what is the probability of not getting the result

Ira Lisetskai [31]

Answer:

100%-75.3%

Step-by-step explanation:

The total probability of all outcomes is 100%.

If the probability of a particular result is 75.3% then all other possibilities (not the particular event) must equal 100% - 75.3%.

Anya walked 7/10 km to the bank and then walked 3/4 km to the flower shop. What is the total distance Anya walked? Show your wor

OleMash [197]

Answer:

1 and 9/20

Step-by-step explanation:

add your fractions together 7/10 + 3/4

make them have the same denom 14/20 + 15/20

so its 29/20

to get the mixed fraction, divide 29/20 to get 1.45. The 1 is your whole number. Subtract 20 from 29 to get 9, which is what is remaining, and will go over 20.

With a ruler, Diamond determines the diameter of a golf ball to be 4.2 centimeters (a radius of 2.1 cm) and the diameter of a pr

Troyanec [42]

Answer:

Diamonds is incorrect, because, the volume of the softball is 8 times the volume of the golf ball

Step-by-step explanation:

we know that

The volume of a sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

where

r is the radius

step 1

Find the volume of the golf ball

we have

$r=2.1\ cm\\pi =3.14$

substitute

$V=\frac{4}{3}(3.14)(2.1)^{3}=38.77\ cm^3$

step 2

Find the volume of the the softball

we have

$r=4.2\ cm\\pi =3.14$

substitute

$V=\frac{4}{3}(3.14)(4.2)^{3}=310.18\ cm^3$

step 3

Find the ratio of volumes

Divide the volume of the softball by the volume of the golf ball

$\frac{310.18}{38.77}=8$

That means

Diamonds is incorrect, because, the volume of the softball is 8 times the volume of the golf ball
