Which of the following functions are linear?​

Answer:

C

Step-by-step explanation:

Answer:

1. y = 4x - 27

2. y = -4x - 15

Step-by-step explanation:

If two lines are parallel, then they have the same slope. So, the slope of the line we are looking for needs to be 4. We can start by writing a point-slope equation:

y - y1 = m(x - x1)

We can substitute the values we have, the point we are using is (8, 5) because it needs to be on the line:

y - 5 = 4(x - 8)

We can distribute:

y - 5 = 4x - 32

y = 4x - 27

We are not given the slope-intercept form, so we must divide both sides by two to get it:

y = 1/4 x + 8

A perpendicular line has the slope that is the negative reciprocal of the one that is given. So, the slope of the line would be - 4. We can start by writing a point-slope equation:

y - y1 = m(x - x1)

We can substitute the values we have, the point we are using is (-5, 5) because it needs to be on the line:

y - 5 = -4(x + 5)

We can distribute:

y - 5 = -4x - 20

y = -4x - 15

Step-by-step explanation:

A) = 54 so it is wrong

B) = 78 so it is wrong

C) = -2 so it is right!

No need to do D since we already found the correct answer.

I hope I helped! :)

Step-by-step explanation:

To find purple, you divide 162 by 3 as there are 3 people who like red for every one person who like purple. To find blue, you need to divide 162 by 3, which is 54, and then multiply it by 9 because there were 9 people who like blue for every person that liked purple.

Answer:

87.92 inches cubed or 87.92 in.^3

Step-by-step explanation:

The base of a cylinder is a circle, so we need to calculate the area of the circle first. The equation for the area of a circle is:

area (a) = pi * r^2 =3.14*2*2 =12.56sq.inches

again,

volume of cylinder = area of the base * the height

= 12.56 * 7

= 87.92 inches cubed or 87.92 in.^3

Answer:

[tex]5.2\:\mathrm{in}[/tex]

Step-by-step explanation:

We can set up the following proportion and solve for length ([tex]\ell[/tex]):

[tex]\frac{2}{5}=\frac{\ell}{13},\\\\\ell=\frac{2\cdot 13}{5}=\frac{26}{5}=\boxed{5.2\:\mathrm{in}}[/tex]

Answer:

she can conclude that 20 percent of the students in the sample use the streaming service.

Answer:

11 sq units

Step-by-step explanation:

(6×4) - ½(6×1 + 4×3 + 2×4)

= 24 - ½(6+12+8)

= 24 - ½(26)

= 24-13

= 11 sq units

Answer:

430.93 miles (rounding to the nearest hundredth)

Step-by-step explanation:

s = 93 log(d) + 65

310 = 93 log(d) + 65

245 = 93 log(d)

2.634408602 = log(d)

10^2.634408602 = 10^log(d)

430.9318583 = d

Therefore, if the speed of the tornado is 310 mph, then its distance is about 430.93 miles.

Answer:

1) 3 miles/h

2) 3 miles

Step-by-step explanation:

6 miles/2h = 3 miles/h

4h = 12 miles

3h = 9 miles

12 - 9 = 3

Answer:

1 is 3 miles an hour and 2 is 3 miles

Answer:

8x=p

Step-by-step explanation:

So 8 time the number of hours Carmen works which I used x. Then you’ll get the total.

Step-by-step explanation:

a^2 + 2(b - 6) - 17. a = -7 b = 2

= (-7)^2 - 2(2 - 6) - 17

= 49 - 4 + 12 - 17

= 40

Answer: A.

Step-by-step explanation:

Answer:

its A

Step-by-step explanation:

Answer:

184

Step-by-step explanation:

V=lwh

(4)(5)(2) = 40

(7)(4)(3) = 84

(2)(5)(4) = 60

40 + 84 + 60 = 184

Answer:

39

Step-by-step explanation:

She sold more than half of the tickets, so the answer is more than 25.

78% of 50 = 39.

39 tickets

[tex] \sqrt{25} = 5 \\ \sqrt{16 } = 4 \\ \sqrt{49} = 7[/tex]

5+4-7 = 9-7 = 2

Our Answer 2

Answer:

The answer is 2

Step-by-step explanation:

√25 = 5

√16 = 4

√49 = 7

Now,

√25 + √16 - √49

5 + 4 - 7

9 - 7 = 2

Thus, The answer is 2

15 x 8 x 11 is greater than one yard of fabric

Step-by-step explanation:

Volume of a rectangular prism = length x width x height

15 x 8 x 11 = 1320 in^3

1 yard = 36 inches

1320 is greater than 36 inches. she does not have enough yard of fabric

Answer:

If s₃ is the length of the 3rd side, the possible values are in the interval.

5 < s₃ < 19

Step-by-step explanation:

For a triangle, we know that the sum of any two sides is always larger than the other side.

So if a triangle has 3 sides:

s₁, s₂, and s₃, we have:

s₁ + s₂ > s₃

s₁ + s₃ > s₂

s₂ + s₃ > s₁

In this case, we know that two sides are:

s₁ = 7

s₂ = 12

And we want to find the possible values of s₃.

Then if we use the above inequalities, we get:

7 + 12 > s₃

7 + s₃ > 12

12 + s₃ > 7

With the first one we get:

19 > s₃

Now we can rewrite the other two as:

s₃ > 12 - 7 = 5

s₃ > 7 - 12 = -5

The first one is more restrictive than the second:

s₃ > 5 > -5

So we can use only the first one.

Then the two inequalities are

s₃ > 5

s₃ < 19

Then the range is:

5 < s₃ < 19

This means that any value between 5 and 19 can be a possible length of the third side (5 and 19 are not possible lengths)
