Count to find the slope. Write your answer clearly.​

Answers

Answer:

[tex]-\frac{1}{4}[/tex]

Step-by-step explanation:

To find the slope by graph, we can use [tex]\frac{rise}{run}[/tex]

The point (5, -3) rise 1 and run 4 to get to (1, -2).

However, the function run from the upper quadrant to the bottom quadrant making it negative.

-1/4 is the slope of the equation. reading from left to right is it is going down it is negative. also remember rise over run. go up then over. or down then over if it is a negative slope lol

Find the value of x that makes Triangle DEF~ triangle XYZ.

Answers

Answer:

x = 4

Step-by-step explanation:

DE / XY = EF / YZ

5 / 10 = 2x-1 / 14

cross-multiply:

10(2x-1) = 14(5)

20x - 10 = 70

20x = 80

x = 4

The ratio of their corresponding side will remain constant. Then the value of x is 4.

What is the triangle?

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

The two triangles are ΔDEF and ΔXYZ.

It is given that the ΔDEF and ΔXYZ are similar.

Then the ratio of their corresponding side will remain constant. That is

[tex]\rm \dfrac{5}{10} = \dfrac{2x -1 }{14} =\dfrac{11}{5x +2 }[/tex]

From the first two, we have

[tex]\rm \dfrac{5}{10} = \dfrac{2x -1 }{14}\\[/tex]

On simplifying, we have the value of x

x = 4

What value of x satisfies the equation below?
[tex]\frac{-2x - 6}{5} = 4[/tex]

Answers

Answer: -13

Step-by-step explanation:

1. Isolate x: move 5 to the otherside

=> -2x-6=4*5 => -2x-6=20

2. Move 6 to the otherside: -2x=20+6 => -2x=26

3. Divide both sides by -2

=> x=26/-2 => x=-13

help me with this please

Answers

Answer:

Step-by-step explanation:

if 45+47=t and t=45+47    t would equal 92 in both

45+47<t than t<45+47

so basically its saying 92<t (92is less than t)  and t<92 (t is greater than 92)

he is not right. When you have an equation like that the answer is 92. Its not going to be greater or less than 92. It is 92. It should be t=92

hope that masks some kind of sense. It after 1am here so I apologize if it doesn't sound right...

Frank made cookies for his class. He gave away half of them in his first period class, but then his mom dropped off 12 more cookies. If he now has 32 cookies, how many did he start with?

Answers

Answer:

Work backwards to solve this problem.

If he ends with 32 cookies, then subtract 12. That gives 20 cookies. 20*2 is 40, so now he has 40 cookies.

Working alone it takes mark 7 hours to mop the whole house it takes sue 9 determine to the nearest hundredth of the hour how long it will take then to mop the house together

Answer:

3.9375 hours

Step-by-step explanation:

Working alone it takes mark 7 hours to mop the whole house it takes sue 9 determine to the nearest hundredth of the hour how long it will take then to mop the house together

This is calculated as

1/Time it would take them to work together = 1/ Number of hours Mark mopped + 1/ Number of hours Sue mopped

= 1/T = 1/7 + 1/9

Lowest common denominator = 63

1/T = 9 + 7/63

1/T = 16/63

T = 63/16

T = 3.9375 hours
