Answer:

d=6.08

Step-by-step explanation:

The points given on the graph are (3,1) and (4,-5). Using this information, we can plug the points into the distance equation.

The first point = $(x_{1} , y_{1} )$

The second point = $(x_{2}, y_{2})$

$d=\sqrt{(x_{2}-x_{1})^2 +(y_{2} -y_{1})^2 }$

$d=\sqrt{(4-3)^2+((-5)-1)^2\\} \\d=\sqrt{(1)^2+(-6)^2}\\d=\sqrt{1+36} \\d=\sqrt{37} \\d=6.08$

A line through the points $(2, -9)$ and $(j, 17)$ is parallel to the line $2x + 3y = 21$. What is the value of $j$?

lys-0071 [83]

Answer:

j=-37

Step-by-step explanation:

step 1

Find the slope of the given line

we have

$2x+3y=21$

Convert to slope intercept form

Isolate the variable y

subtract 2x both sides

$3y=-2x+21$

divide by 3 both sides

$y=-\frac{2}{3}x+7$

The slope is

$m=-\frac{2}{3}$

step 2

we have the points

(2,-9) and (j,17)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute

$m=\frac{17+9}{j-2}$

$m=\frac{26}{j-2}$

Remember that

If two lines are parallel then their slope are equal

therefore

$\frac{26}{j-2}=-\frac{2}{3}$

$26(3)=-2(j-2)\\78=-2j+4\\2j=4-78\\2j=-74\\j=-37$

What is the sum of the series?

pav-90 [236]

For this case we must find the sum of the given series. For this we must expand the series for each value of k.

$(-2 (3) +5) + (- 2 (4) +5) + (- 2 (5) +5) + (- 2 (6) +5) =\\(-6 + 5) + (- 8 + 5) + (- 10 + 5) + (- 12 + 5) =$

Different signs are subtracted and the sign of the major is placed, while equal signs of sum and the same sign is placed.

$-1-3-5-7 =\\-16$

The value of the series is -16

Nick randomly selects a digit from the set { 0 , 1 , 2 , . . . , 9 } and a letter from the set { A, B, C, . . ., Z } . Matthew w

Alex787 [66]

Answer: 259/260 or 0.99615 (depending on which answer format your teacher wants)

There are 10 numbers in the set {0, 1, 2, ..., 9}. There are 26 letters in the set {A, B, C, ..., Z}. Multiply those values: 10*26 = 260. So there are 260 ways to pick a number followed by a letter. One example is 7P.

There is only one way Matthew can get the correct answer, and there are 260 - 1 = 259 ways to get the wrong answer. We divide 259 over 260 to get the probability of getting the incorrect answer, which is 259/260.

If you need this fraction in decimal form, then use a calculator to find that 259/260 = 0.99615 approximately
