Step-by-step explanation:

y=-2x+2

y=mx+b

m is slope so.here m is -2

y=-2+10.passes through the point (3,-4)

Answer:

6 rooms

Step-by-step explanation:

20+12x=30+10x

12-10=2

20+2x=30

30-20=10

2x=10

10/2=5

5 rooms to make them equal so 6 rooms to make captain datalot more

The inequality is 20+12x> 30 +10x.

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

Given:

Captain Dustsalot charges

$20 per house call

$ 12 per room

Dedusters charges

30 per house call

$10 per room

let  x represents the number of rooms she gets dusted.

so, inequality that represents rooms she must get dusted so that Captain Dustsalot is more expensive than Dedusters.

Answer: b. -1/2

Step-by-step explanation:

First you need to choose 2 points in the graph

I chose (0,4) and (-2,3)

After chosing 2 points you have to plug them in the slope formula

m= y2-y1/x2-x1

m= 3-4/-2-0

m= -1/-2

Answer:

Look at the picture. M angle1= M angle 3 might be wrong

Angle 1 and angle 2 are supplementary, so p and a are parallel by transversal properties and angle congruence.

as it is already stated that Angle 1 and angle 2 are supplementary.

from the angle 2 and 3 are supplementary according to linear pair postulate
Supplementary angles add up to 180 degrees, so we have:

angle 1 + angle 2 = 180

Using the characteristics of parallel lines and transversals, we can determine that if angles 1 and p are complementary and angles 1 and 2 are congruent, then angles p and 2 are also complementary.

according to transitive property of equality

angle1 +angle 2= angle 3+ angle 4

consecutive interior angle theorem
angle 1 = angle 3

∠1≅∠3

lines converse angles converse.

Answer:8

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the expression

y = 19.75x

let us see the solution from this angle

we know that

speed=distance/time

distance=speed*time

i.e quantity=rate*time

y = 19.75x

y=the quantity =number of gallons

19.5= the rate of flow

therefore

x= the time in  minutes

Step-by-step explanation:

4 is the GCF od 12, 16 and 20

Answer:

4

Step-by-step explanation:

The greatest common factor is the largest number that is a shared factor of all 3 numbers (the greatest number they can all divide into). To find the GCF, we can list all the factors of the 3 numbers and then find the largest one that is common to all three sets.

Factors of 12 are: 1,2,3,4,6,12

Factors of 16 are: 1,2,4,8,16

Factors of 20 are: 1,2,4,5,10,20

We can see that 1,2 and 4 are the numbers common to all three sets but 4 is the largest so 4 is our greatest common factor.

Answer:

(a) The system of equations is:

2r + b = 8.40

3r + b = 9.35

(b) The graph is attached down

(c) By using the graph

The cost of the refill is $0.95

The cost of the egg breakfast is $6.5

Step-by-step explanation:

Let r is the amount charged for a refill and b for  the amount charged for the egg breakfast

∵ r is the amount charged for a refill

∵ b is the amount charged for the egg breakfast

∵ You ordered 2 drink refills and the egg  breakfast, for a total of $8.40

∴ 2r + b = 8.40 ⇒ (1)

∵ Your friend ordered 3 refills and the egg breakfast for $9.35

∴ 3r + b = 9.35 ⇒ (2)

(a) The system of equations is:

2r + b = 8.40

3r + b = 9.35

(b) The graph is attached down

From the graph

The red line represents equation (1)

The blue line represents equation (2)

The two lines intersected at point (0.95, 6.5)

(c) By using the graph

The cost of the refill is $0.95

The cost of the egg breakfast is $6.5

Answer:

The new coordinates of the triangle J'K'L' are J'(0, -3), K'(3, -4), and J'(6, 0)

Step-by-step explanation:

The given coordinates of the triangle JKL are;

J(3, 0), K(4, 3), L(6, 0)

The rotation of the point of a preimage (x, y) by 90° clockwise gives the point of the image after rotation as (y, -x)

Therefore;

The rotation of point J(3, 0) by 90° clockwise gives J'(0, -3)

The rotation of point K(4, 3) by 90° clockwise gives K'(3, -4)

The rotation of point L(6, 0) by 90° clockwise gives J'(6, 0)

The new coordinates of the triangle J'K'L' are J'(0, -3), K'(3, -4), and J'(6, 0)

Answer:

2. -1.5, 0

3. -6, 9

5. 3, -9

Step-by-step explanation:

Given parameters:

    Slope  = -2

    y - intercept  = -3

Unknown:

The point that lies on the line  = ?

Solution:

 To do the equation of the line,

        y  = mx + c

y and x are the coordinates

m is the slope

c is the y -intercept

Input the parameters:

            y= -2x -3

The points that lie on the line will conform with the equation:

          y + 2x  = -3

1. -2, 0

   y = 0 and x = -2

       0 + (-2)2 = -4

2. -1.5, 0

  y = 0 and x = -1.5

      0 + 2(-1.5) = -3

3. -6, 9

   y = 9, x  = -6

    9 + 2(-6) = 9 - 12 = -3

4. 2, -3

    y = -3 and x = 2

    -3 + 2(2) = -3 + 4 = 1

5. 3, -9

    y = -9, x  = 3

      -9 + 2(3) = -9 + 6 = -3

6. -4, 4

    y = 4 , x - 4

       4 + 2(-4) = 4 - 8 = -4

The boldened coordinates line on the same line.

Answer:

m⊥ = –½

Step-by-step explanation:

First, put the given equation in slope-intercept form:

2x – y = –6

–y = –2x – 6

y = 2x + 6

The slope of the line perpendicular to the line given will be the negative reciprocal of the given line's slope, so:

If m = 2, then m⊥ = its negative reciprocal:

m · –1

2 · –1

–2  →  –½

So, the negative reciprocal of 2 is –½.

Answer:

Step-by-step explanation:

Given that the cost of the ticket is

$43.32

and the price decrease is by $0.25

let the cost be C

and let the number of losses be L

the expression for the cost we be

C=43.32-0.25L

for the number of losses which is 22 we have

C=43.32-0.25(22)

C=43.32-5.5

C=37.82

Therefore the price after 22 losses is $37.82
