Answer:

y = - 3x + 11

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{3}[/tex] x - 3 ← is in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3, then

y = - 3x + c ← is the partial equation

To find c substitute (3, 2) into the partial equation

2 = - 9 + c ⇒ c = 2 + 9 = 11

y = - 3x + 11 ← equation of perpendicular line

Answer:

68 degrees

Step-by-step explanation:

The sum of two complementary angles is 90 degrees

If <a and <b are complementary, then;

<a + <b = 90

Given

<a = 22 degrees

Required

<b

Substitute into the given expression;

22 + <b = 90

<b = 90-22

<b = 68 degrees

Hence the measure of <b is 68 degrees

Answer:

(A) You will have to finish the assignment yourselves.

Step-by-step explanation:

In B, C, and D, the "yourself" and "myself" words aren't adding any emphasis to the situation! But in sentence (A), the speaker is saying that, you will have to finish the assignment YOURSELF. No help from anyone else! (This implies that the task might be difficult, putting emphasis!)

Kindly check explanation

Step-by-step explanation:

The initial elevation is 20m

According to the question :

If it changes to 16m, then the final elevation of the bird is 16 m.

However, in some texts, the question goes thus;

A bird starts at 20m and changes 16m? The bird's final elevation is?

In this case, the initial height = 20m

Change in height = 16 m (positive means ascension)

Hence,

initial height + change in height

20 m + 16 m

= 36m

Answer:

9.8

Step-by-step explanation:

The crew worked for 4 1/5 days

They built 2 1/3 kilometres of road each day

Therefore the total length of the road can be calculated as follows

= 4 1/5 × 2 1/3

= 21/5 × 7/3

= 147/15

= 9.8

Hence the length of the road is 9.8 kilometres

Answer:

$6.72

Step-by-step explanation:

1.68 is 7% of 24, so there is a 7% tax.

96x.07= 6.72

Answer:  The sales tax would be 6.72

Step-by-step explanation: 24 is 1/4 of 96 so that means that you have to multiply the sales tax number by 4 and 1.68 x 4 = 6.72

Answer:

y = 1 , x = 3

Step-by-step explanation:

3x + y = 10

x = 2y + 1

3(2y + 1) + y = 10

6y + 3 + y = 10

7y = 7

y = 1

x = 2(1) + 1

x = 3

Answer:

No. The margin of error only includes sampling variability.

Step-by-step explanation:

The margin of error would be considered for the sampling error

In the case when some adults does not have telephones so it is called as error selection bias this is not a sampling error

The selection bias, unresponse bias and the response would be the examples of an error but it is not a sampling errors

So there is no margin of error as it only involved the variability in the sampling

Answer:

5/8

Step-by-step explanation:

Aquí, queremos encontrar la suma al infinito de la progresión geométrica, dado el primer término y la razón común Matemáticamente, eso sería;

S = a/1-r

S = 1/2/(1-1/5)

S = 1/2/4/5

S = 1/2 * 5/4

S = 5/8

Answer:

y=-7x -2

Step-by-step explanation:

use formula to find the equation when you know slope and a point

it is: y-y1 = m(x-x1)

plug in values

y-(-30) = -7(x-4)

y+30 = -7x + 28

- 30 from both sides

y = -7x -2

Answer:

The values of x that make the triangles congruent.

x = 6 and x = 3

Step-by-step explanation:

Given

Given that the triangles are congruent.

According to the SAS (Side-Side-Side)

AC = DC

AB = DB

so

AC = DC

substituting AC = 5x-2 and DC = 3x+10

5x-2 = 3x+10

5x-3x = 10+2

2x = 12

divide both sides by 2

2x/2 = 12/2

x = 6

and

AB = DB

substituting AB = 5x and DB = 4x+3

5x = 4x+3

5x-4x = 3

x = 3

Therefore, the values of x that make the triangles congruent.

x = 6 and x = 3

Step-by-step explanation:

Answer:

y = 18 - 6x

Step-by-step explanation:

Given :

Speed or rate = 6mph

y = distance away from home

x = hours biked

Initial distance from home = 18 miles

General form of Slope - intercept form of an equation :

y = mx + c

Where ;

m = gradient or slope = rate of change

c = intercept or initial value or amount, always constant

x = independent variable

y = dependent variable

Hence,

For the question above :

Distance away from home, depends on the number of hours biked

y = 18 - 6x

Answer:

its many solutions

Step-by-step explanation:

Answer:

The volume of the given figure is 150 mm³

Step-by-step explanation:

The formula of the volume of the triangular pyramid is V = [tex]\frac{1}{3}[/tex] AH, where

The formula of the area of a triangle is A = [tex]\frac{1}{2}[/tex] bh, where

In the given figure

∵ The pyramid has a triangular base

∵ The triangle has a base of 12 mm and a height of 7.5 mm

∴ b = 12 mm and h = 7.5 mm

→ By using the 2nd formula above, find the area of the base

∴ A = [tex]\frac{1}{2}[/tex] (12)(7.5)

∴ A = 45 mm²

∵ The height of the pyramid is 10 mm

∴ H = 10 mm

∵ A = 45 mm²

→ Substitute them in the first formula above to find the volume

∴ V = [tex]\frac{1}{3}[/tex] (45)(10)

∴ V = 150 mm³

∴ The volume of the given figure is 150 mm³
