[tex](5)\ y = -3x -2[/tex]

Step-by-step explanation:

The equation in slope intercept form

Solving (3):

[tex]m = -1[/tex]

[tex](x_1,y_1) =(4,-4)[/tex]

The equation in slope intercept form is:

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

This gives:

[tex]y = -1(x - 4) -4[/tex]

Expand

[tex]y = -x + 4 -4[/tex]

[tex]y = -x[/tex]

Solving (5):

[tex]m = -3[/tex]

[tex](x_1,y_1) = (1,-5)[/tex]

The equation in slope intercept form is:

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

This gives:

[tex]y = -3(x - 1) - 5[/tex]

Expand

[tex]y = -3x + 3 - 5[/tex]

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

Answer:

Billy would need to mow 4 laws to make over $25.

Answer and Step-by-step explanation:

We are given a triangle and are asked to solve for the value of y.

We know that the angles in a triangle add up to 180 degrees. So let's add all of the angles together and equal it to 180.

2y + y + 10 + 50 = 180

Combine like terms.

3y + 60 = 180

Now subtract each side by 60.

3y = 120

Finally, divide each side by 3.

y = 40

We get the value of y to be 40.

Answer:

54

Step-by-step explanation:

What I would do is multiply 12x4 first to get 48, then after I'd multiply 12x1/2 to get 6 then I'd add them together to get 54.

Answer:

what is question 10?

Step-by-step explanation:

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Answer:

The claim is true for all values of m.

Step-by-step explanation:

Given

[tex]y = 2 + mx[/tex]

Required

Which claim is true [See comment for options]

A linear equation is represented as:

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

Where

[tex]m = slope[/tex]

And the value of m knows no bound

i..e

[tex]m > 0[/tex]

[tex]m = 0[/tex]

[tex]m < 0[/tex]

Hence, (a) is correct

Step-by-step explanation:

7/10 + 1/5 =

7/10 + 2/10  (1/5 x 2 = 2/10) = 9/10

10/10 - 9/10 = 1/10

therefore, 1/10 of the class rides on the school bus.

Answer:

B.) 3x=15

Step-by-step explanation:

This is because you multiply 3 by x and if x=5 then it would be 3x5 thus resulting in 15

1) Plug 5 into all the spots for x. See if it makes the equation true.

A. 2+5 = 3  Nope

B. 3(5) = 15 Yep

C. 5/2 = 10 Nuh-uh

D. 5-7 = 12  Nah

B is the answer :)

I'm not sure if you need the answer to #2 but I'll answer it anyway. :)

2) An equation has to have a solution. This means it has an equal sign. C is the only one that has an equal sign.

C is the answer :)

Answer:

0.22

Step-by-step explanation:

defective rate is 7 out of 100

defective rate of 4, or 3, or 2, or 1 defective is:

7/100 + 6/99 + 5/98 + 4/97 ≈ 22/100

The required probability for fewer than 5 defective rate is 0.10

An industrial machine produces widgets, but it has a 0.07 defective rate.

What is the probability?

Probability, can be define as the ratio of favorable events to the n number of total events.

defective rate fewer than 5

p of 4 defective + p for 3 defective+ p for 2 defective + p for  1 defective.

total p = 4/100 + 3/99 + 2/98 + 1/97 ≈ 0.10

Thus, The required probability for fewer than 5 defective rate is 0.10

Answer:

x=26/7

y=115/7

Step-by-step explanation:

7x+10=36>>subtract 10 from 10 and 36 you get 7x=26>>>divide both sides by 7>>>>x=26/7

To find find y you substitute the x for 26/7>>2(26/7)+9=115/7

Answer:

Below.

Step-by-step explanation:

The parabola will open to the right and will be symmetrical about y = 3.

The vertex is halfway between x = 1 and x = -7 making it at (-3, 3).

The p value is the distance between the vertex and the focus - here it is 1 - -3

= 4.

Answer:

The parabola has a vertex at (-3, -6), has a p-value of 4 and it opens right.

Answer:

m∠b=m∠c=61°

Step-by-step explanation:

The 119° angle and ∠b/∠c are supplementary angles. ∠b and ∠c are congruent because they are vertical angles and they are also both supplementary to the 119° angle. I will use b to find c.

[tex]b+119=180[/tex]

[tex]b=61[/tex]

Since b and c are equal, c=61 too.

Answer:

84

Step-by-step explanation:

The interquartile range is obtained using the relation :

Third quartile (Q3). - First quartile (Q1)

From. The boxplot :

Q3 = 96

Q1 = 12

Interquartile range (IQR) = Q3 - Q1 = 96 - 12 = 84
