Which pair of points have a slope of -3/5?

A (4, 0), (-2, 10)

B (10, -2), (0, 4)

C (4, 2), (10, 4)

D (-4, -10), (0, -2)

Answers

Answer:

No of these answers has a slope of  [tex]\frac{-3}{5}[/tex] . My guess is B becasue its close to [tex]\frac{-3}{5}[/tex] unless the 5 is supposed to be negative

Step-by-step explanation:

You have to use the slope formula [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

([tex]x_{1}[/tex],[tex]y_{1}[/tex]), ([tex]x_{2}[/tex],[tex]y_{2}[/tex])

(4, 0), (-2, 10)   [tex]\frac{10 - 0 }{-2 - 4 }= \frac{10}{6}[/tex] you have to simplfy, the answer will be [tex]\frac{5}{3}[/tex]

(10, -2), (0, 4)  [tex]\frac{4 - -2 }{0- 10 }= \frac{6}{-10}[/tex] you have to simplfy, the answer will be [tex]\frac{3}{-5}[/tex]

 (4, 2), (10, 4)  [tex]\frac{4 - 2 }{10 - 4 }= \frac{2}{6}[/tex] you have to simplfy, the answer will be [tex]\frac{1}{3}[/tex]

 (-4, -10),(0, -2) [tex]\frac{{-2- -10} }{0 - -4 }= \frac{8}{4}[/tex] you have to simplfy, the answer will be [tex]\frac{2}{1} =2[/tex]

In the first quadrant, you start at (5,7) And move 2 units right and 2 units down What point will you end up on

Answers

Answer: (7,5)
Explanation:
5+2= 7
7-2= 5
(X,Y)
Left to right- the X axis, moving up 2 units so you add 2 to your x value which is 5.

Up and Down- the y axis, moving down 2 units so you subtract 2 from the y value, being 7.

Liam and his children went into a restaurant and where they sell drinks for $2 each and tacos for $3.50 each. Liam has $30 to spend and must buy at least 9 drinks and tacos altogether. If Liam decided to buy 5 tacos, determine the maximum number of drinks that he could buy. If there are no possible solutions, submit an empty answer.

Answers

answer: the maximum number of drinks Liam can buy is 4 without over exceeding his price limit.

work:
$3.50 for 5 tacos is $17.50
9 - 5 tacos = 4 drinks
4 drinks x $2 = $8
$17.50 + $8 = $25.50 out of $30 price limit

Answer:

Step-by-step explanation:

I think if im wrong my apologies haven't done that in a bit

The weight of Audrey will be 14 pounds based on the given equation formation.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

Suppose the weight of Asher is x then according to the given question,

x = 3w - 15

And, x = 27

27 = 3w - 15

3w = 42

w = 14 pounds

Hence "Weight of Audrey will be 14 pounds based on the given equation formation".

Answer:

I am not sure but for

CAE it is 65˚

CBD it is 65˚

Step-by-step explanation:

x+40=3x-10

Move the 3x to the other side by subtracting by 3x on both sides

x-3x+40=3x-3x-10

The equation now looks like this:

-2x+40=-10

Move 40 to the other side by subtracting 40 both sides:

-2x+40-40=-10-40

-2x=-50

Divide by -2 on both sides:

-2x/-2=-50/-2

x=25

Since we found out what x is we can replace x in both CAE and CBD:

For CBD: 25+40 is 65

For CAE: 3(25)-10 is 65

Answer:

m∠CAE = 65, m∠CBD = 65

Step-by-step explanation:

Line CA is a transversal of lines AE and BD which are parallel, in this case corresponding angles are congruent. ∠CAE and ∠CBD are corresponding angles so you can make them equal to each other. x+40=3x-10 -> 2x=50 ->x=25. Now that we have x just plug it into the equations 25+40=65 which is m∠CBD. 3(25)-10=75-10=65 is m∠CAE

Step-by-step explanation:

Subtract 29 from both sides

-14k+29-29=71-29

Simplify

-14k=42

Divide both sides by -11

-14k/-14=42/-14

6. -33=19-13x

Subtract 29 from both sides

Divide both sides by -14

-14k/-14=42/-14

Simplify

k=-3

7. 8+n/25=-4

Multiply both sides by 25

25(8+n)/25 = 25 (-4)

Subtract 8 from both sides

4+2(8²×4²)+6+4+6+6+6+2+2​

Answers

Answer:

2084

Step-by-step explanation:

4+2(8²×4²)+6+4+6+6+6+2+2​ = 4+2(64*16)+6+4+6+6+6+2+2 = 4 + 2048 + 6 * 5 + 2 = 4 + 2050 + 30 = 2080+4 = 2084​

4 + 2(8^2 * 4^2) + 6 + 4 + 6 +6 + 6 + 2 + 2
= 4 + 2(64 * 16) + 6 + 4 + 6 + 6 + 6 + 2 + 2
= 4 + 2(1024) + 6 + 4 + 6 + 6 + 6 + 2 + 2
= 4 + 2048 + 6 + 4 + 6 + 6 + 6 + 2 + 2
= 4 + 2048 + 24 + 4 + 4
= 2048 + 12 + 24
= 2048 + 36

So, in conclusion, the answer to this question is: 2048.

Josh can long-jump 195% of his height with a running start. If Josh is 66 inches tall, how far can he long-jump?

Answers

Answer: 128.7 inches

Step-by-step explanation:

Josh's height is 66 inches.

When he jumps with a running start, he can jump as far as 195% of his height.

The length he can jump is therefore 195% multiplied by his height:

= Josh height * 195%

= 66 * 195/100

= 128.7 inches
