Hey there!

We know that the slope intercept is; y = mx+b.

Where "m" represents the slope. And "b" represents the y-intercept.

Example:

If the question is as; y = 3x +8

Then your slope of the slope intercept form is "3" where as "8" is y-intercept.

So, the variable"m" represents the slope.

Answer:

36

Step-by-step explanation:

Answer: 36°

Step-by-step explanation: The three angles of a triangle always equal 180 when added together. Since we have two angles already, we simply subtract those from 180

180 - 115 = 65

65 - 29 = 36

J = 36

Answer: The answer is 60/7 or in mixed number form it is 8 4/7...

to make it easier, all you do is make the fractions improper and then add... If they didn't have the same denominator then you would make them have the same denominator. But they already have the same denominator... Or in other words convert the fractions into improper fractions, then find the LCD and combine... 34/7+26/7

34+26/7

60/7

decimal form: 8.571428

mixed number form: 8 4/7

= about 8.6

Answer:

55

Step-by-step explanation:

Assuming that, initially, there were x people at the time of planning.

As given that, initially, the cost for 1 person = € 20

So, Total cost = € 20x ...(i)

As on the day of the outing, five people cannot come, so the number of people on the outing = x-5.

Now, due to the lesser number of people, i.e (x-5), the cost for 1 person = € 22.

Total cost = € 22(x-5) ...(ii)

As total cost remains the same, so equation the total cost from equations (i) and (ii), we have

[tex]20x= 22(x-5) \\\\\Rightarrow 20x=22x-22\times 5 \\\\\Rightarrow 22x-20x= 110 \\\\\Rightarrow 2x=110 \\\\\Rightarrow x=110/2=55.[/tex]

Hence, at the time of planning, there were 55 people.

Answer:

Step-by-step explanation:

2x + 18 = 5x

18 = 5x - 2x

3x = 18

x = 6

a)  find m∠BAC

substitute x=6 to ∠BAC

∠BAC = 2x + 18

          = 2(6) + 18

          = 30°

b)  find m∠B

∠B = 180 - ∠A - ∠C

    = 180 - 30 - 30

     = 120°

c) find m∠BAG

∠BAG = 180 - ∠A

          = 180 - 30

          = 150°

Answer: 114%

Step-by-step explanation:

From the question, we are informed that it usually takes Roger's father 35 minutes to get to work but that after the snowstorm it took him an hour and 15 minutes to get to work.

We should first convert 1 hour, 15 minutes to minutes. Since 60 minutes = 1 hour; Therefore, 1 hour, 15 minutes = 60 minutes + 15 minutes = 75 minutes.

The percent increase in his commute time to work will then be:

= [(75 - 35) / 35] × 100

= 40/35 × 100

= 114.28571%

= 114%

The percentage increase is 114%.

1.5 : 2.5

= 1.5/2.5

15/25

3/5

the ratio is 3 : 5

The ratio of 1.5-inch screws to 2.5-inch screws is 3/5.

Given,

- 1.5 inch screws

- 2.5-inch screws

We need to find what is the ratio of 1.5-inch screws to 2.5-inch screws.

Ratios are denoted by A:B.

Example: 1/2, 3/4

If two ratios are equal we called the ratios are in proportion.

Example:

1/2 and 5/10

5/10 = 1/2

We have,

1.5 and 2.5

We can write it as:

= 1.5 : 2.5

= 1.5 / 2.5

= 150 / 250

= 15/25

= 5x3 / 5x5

= 3/5

Thus the ratio of 1.5 and 2.5 is 3/5,

Answer:

n = 6

Step-by-step explanation:

9n - 24 = 4n + 6              {Subtract 4n from both sides }

9n - 24 -4n = 6

       5n - 24 = 6               {Add 24 to both sides}  

               5n = 6 + 24

               5n = 30

                 n = 30/5

n = 6

Answer:

n=6

Step-by-step explanation:

Simplifying

9n + -24 = 4n + 6

Reorder the terms:

-24 + 9n = 4n + 6

Reorder the terms:

-24 + 9n = 6 + 4n

Solving

-24 + 9n = 6 + 4n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-4n' to each side of the equation.

-24 + 9n + -4n = 6 + 4n + -4n

Combine like terms: 9n + -4n = 5n

-24 + 5n = 6 + 4n + -4n

Combine like terms: 4n + -4n = 0

-24 + 5n = 6 + 0

-24 + 5n = 6

Add '24' to each side of the equation.

-24 + 24 + 5n = 6 + 24

Combine like terms: -24 + 24 = 0

0 + 5n = 6 + 24

5n = 6 + 24

Combine like terms: 6 + 24 = 30

5n = 30

Divide each side by '5'.

n = 6

Simplifying

n = 6

Given:

The equation of line is

[tex]y=-3x+2[/tex]

To find:

The equation of line parallel to given line and passes through (-5,-8).

Solution:

Slope intercept form of a line is

[tex]y=mx+b[/tex]

where, m is slope and b is y-intercept.

On comparing the equation [tex]y=-3x+2[/tex] with the slope intercept form, we get

[tex]m=-3[/tex]

Slope of given line is -3.

Slope of two parallel lines are same. So, the slope of parallel line is -3.

Equation of line passes thorough the point (-5,-8) with slope -3 is

[tex]y-y_1=m(x-x_1)[/tex]

where, m is slope of the line.

[tex]y-(-8)=-3(x-(-5))[/tex]

[tex]y+8=-3(x+5)[/tex]

[tex]y+8=-3x-15[/tex]

Subtract 8 from both sides.

[tex]y=-3x-15-8[/tex]

[tex]y=-3x-23[/tex]

Therefore, the equation of required line is [tex]y=-3x-23[/tex].
