what is the slope of the line that passes through the points (-1,-7) and (-2,-5)

Answers

Answer 1

Answer:

The equation of the straight line is

2 x + y +9=0

Step-by-step explanation:

Step(i):-

Given that the points are ( -1 , -7) and ( -2 , -5)

Slope of the line

[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{-5-(-7)}{-2-(-1)} = \frac{-5+7}{-2+1} = -2[/tex]

Slope of the line  m = -2

Step(ii):-

The equation of the straight line passing through the point (-1,-7) and having slope m =-2

[tex]y - y_{1} = m( x- x_{1} )[/tex]

y - (-7) = - 2( x-(-1))

y +7 = -2 ( x +1)

y +7 = -2 x -2

2 x + y + 7 + 2 =0

2 x + y +9=0

Final answer:-

The equation of the straight line is

2 x + y +9=0

A shoe store is having an After Holiday sale and everything must go! If all the shoes are marked 60% off, how much do you pay for 2 pairs of shoes that cost $45 and $75?

Answers

Answer:

$48

Step-by-step explanation:

Find 1% of each pair of shoe first.

1 pair of shoe which cost $45:

100% = 45

1% = 45 ÷ 100 = 0.45

Other pair of shoe which cost $75:

100% = 75

1% = 75 ÷ 100 = 0.75

Now find 60% of each pair, the sale percentage.

1 pair of shoe which cost $45:

60% = 0.45 x 60 = $27

Other pair of shoe which cost $75:

60% = 0.75 x 60 = $45

Now, do full price - 60% of it.

$45 - $27 = $18

$75 - $45 = $30

Now add them up.

$18 + $30 = $48

On the playground, 1/4 of the students are on the jungle gym, and 1/3 f the students are playing kickball. What part of all the students on the playground is on the jungle gym or playing kickball?

Answers

Answer:

7/12 of the students

Step-by-step explanation:

So first you would need to get your fractions to have the same denominator. When your trying to get your fractions to get the same denominato. You must multiply both the numerator and denominator.

The most common denominator from 1/4 and 1/3 is 12. So you multiply both the numerator and denominator of 1/4 by 3. So then your new fraction is 3/12. Now you multiply 1/3, both numerator and your denominator by 4. Then your new fraction is 4/12. So The last step is to add both of your numerators. Never add the denominators together. And at last you have your answer. 7/12.
