Answer: y = mx + b

4x - 6y = 10

-6y = -4x + 10

y = (-4/-6)x + 10/-6

y = (2/3)x - 5/3

m = 2/3

b = -5/3

Answer:

open the brackets of two sides

ie; 1.5x+6-3=4.5x-9

1.5x+3=4.5x-9

4.5x-1.5x=3+9

3x=12

X=4

Answer:

8

Step-by-step explanation:

When doing these types of problems, we convert the percent to a decimal. In this case,

40%=0.4

0.4*20=8

Answer:

200%

Step-by-step explanation:

20 = 100%       (in this case)

40 = 200%        (because you multiply both sides to get 40)

Therefore, 40 is 200% of 20.

Answer:

3.2

Step-by-step explanation:

Answer:

Step-by-step explanation:

For graph (a),

Let the equation of the line is,

Ax + By = C

For the line passing through (4, 0) and C = 24,

4A + B(0) = 24

4A = 24

A = 6

For a point (0, -3) lying on this line,

A(0) + B(-3) = 24

-3B = 24

B = -8

Therefore, equation of the line will be,

6A - 8B = 24

3A - 4B = 12

b). If the equation of the given line is,

Ax + By = 24

For a point (3, 0) lying on the line,

3A + B(0) = 24

A = 8

For a point (0, 2) lying on the line,

A(0) + 2B = 24

2B = 24

B = 12

Therefore, equation of the given line will be,

8A + 12B = 24

2A + 3B = 6

Answer:

x is -9

CB is 10

Step-by-step explanation:

In order to solve this question we need to figure out what x is first

First we do

2(x+19)=x+29

Then we get 2x+28=x+29

subtract and divide to get

x=-9

Plug in the x to get CB

-9+19=10

Answer:

20 games

Step-by-step explanation:

Lets work backwards; *Adding what he gave away or lost*

-Alex started with 16 video games

-Add the games gave to his brother (+2)

-Add the games he sold (+3)

-The number is 3/4 of his games

-Subtract the games he traded with hector (-1/4)

Equation: 16+2+3-6= 3/4 X (variable) *You can choose other than X*

21-6 = 15

15 = 3/4

Take the reciprical of 3/4 which is 4/3 and multiply it by both sides

4/3 x 15 = 3/4 x 4/3

4/3 X 15 = 20!

Answer:

142.1π in³

Step-by-step explanation:

Given that:

The radius (r) =  7 in

The slant height (y) = 25 in

Then the height (x) can be determined by using the Pythagoras rule:

y² = x² + r²

25² = x² + 7²

125 = x² + 49

125 - 49 = x²

x² = 76

x = √76

x = 8.7

The formula for the volume of a cone is;

= 1/3 πr²h

where;

height(h) is calculated as "x" from above = 8.7

Then;

= 1/3 × π × (7 in)² × 8.7 in

= 142.1π in³

Step-by-step explanation:

Step-by-step explanation:

angle 2 = 2x + 10 deg (corresponding angles) or 180 - 4x + 46 deg (angles on a straight line are supplementary)

therefore,

2x + 10 = 226 - 4x

6x = 216

x = 36

hence,

angle 2 = 2(36) + 10 = 82deg

Answer:

Cost of shoes = $37.4925

Cost of jacket = $92.4533

Tax = $9.81

Total paid = $144.2458

Step-by-step explanation:

Normal price of shoes = $49.99

Discount = 25%

Discounted price:

[tex]\$49.99 - \$49.99\times \dfrac{25}{100} = \$37.4925[/tex]

Normal price of jacket = $137.99

Discount = 33%

Discounted price:

[tex]\$137.99 - \$137.99\times \dfrac{33}{100} = \$92.4533[/tex]

Price of pack of cookies = $4.49

No discount on cookies as per question statement.

Total amount without tax = $37.4925 + $92.4533 + $4.49 = $134.4358

Sales Tax = 7.3% of total amount without tax = 7.3% [tex]\times[/tex] $134.4358 = $9.81

Total paid = $134.4358 + $9.81 = $144.2458

Answer:

-1

Step-by-step explanation:

Answer: You're answer to you question would be D

Step-by-step explanation:

The correct description of the transformation translation 10 units left and 4 units down. The correct option is D.

The transformation can be defined as the introduction of a new set of mathematical coordinates that are declared to be different functions of the original coordinates.

Given the per-image and image of different points. Now, if we look at the coordinates of the A and A', then it can be observed that if 10 units is deducted from the x-coordinate of A, then the x-coordinate of A' will be the result.

Similarly, if 4 units is deducted from the y-coordinate of A, then the y-coordinate of A' will be the result.

Further, it is known that reducing n units from x-coordinate means that the point is shifted left by n units. Also, if p units are deducted form the y-coordinate then the point is shifted p units down.

Hence, the correct description of the transformation translation 10 units left and 4 units down.

==================================================

Explanation:

p is a placeholder for a number. Think of it like a box where a number goes inside.

In this case, p is the price of one pack of pencils.

We can use a proportion to help set up an equation

(4 packs)/(8 dollars) = (1 pack)/(p dollars)

4p = 8*1 ... cross multiply

4p = 8

8 = 4p  which points to choice A as the answer.

---------------------------

Alternative method:

4 packs = 8 dollars

1 pack = p dollars

Multiply both sides of the second equation by 4 and you'll get

4 packs = 4p dollars

Then replace the "4 packs" on the left hand side with "8 dollars"

8 dollars = 4p dollars

that turns into

8 = 4p

--------------------------

Yet another method:

We know it's $8 for 4 packs. This must mean it is 8/4 = 2 dollars per pack.

If p is the cost of one pack, then p = 2.

Now plug p = 2 into each of the four answer choices. You should find that only 8 = 4p results in a true equation.

Choice B is false because 8 = 4/p turns into 8 = 4/2 and that becomes 8 = 2, which is a false equation. Choices C and D are similar stories.

Answer:

The answer is A
