Answer:

A coordinate grid with 2 lines. The first line passes through (negative 4, negative 3), (0, negative 3), and (4, negative 3). The second line passes through (0, negative 5) and (2, 4). The lines appear to intersect at about one-half, negative 3.

Solve the system of equations algebraically. Verify your answer using the graph.

y = 4x – 5

y = –3

What is the solution to the system of equations?

((StartFraction one-fourth EndFraction, negative 3), –3)

((StartFraction one-half EndFraction, negative 3), –3)

(–3, (negative 3, StartFraction 2 over 3 EndFraction))

Answer:

3.5 Liters

Step-by-step explanation:

Since 500 ml is equal to 0.5 liters and there are 7 days in a single week you just need to multiple the number of liters (0.5) by the 7 days to get a total of 3.5 liters

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

General Formulas and Concepts:

Pre-Algebra

Algebra I

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope-Intercept Form: y = mx + b

Step-by-step explanation:

Step 1: Define

Find points from the graph.

x-intercept (2, 0)

y-intercept (0, -1)

Step 2: Find slope m

Step 3: Write linear equation

y = 1/2x - 1

Answer:

its y = 1/2 x - 1

Step-by-step explanation:

why did math tutor delete my question?!?!??!

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:

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

Answer:

110

Step-by-step explanation:

We have to make sure the denominators are equal.

10 goes into 5 evenly, so we only need to multiply one term to get a common denominator.

Multiply 2 by 2, and get 4, then we multiply 5 by 2 and get 10

Now the equation is 4/10 + 6/10

Since our denominators match, we can add the numerators.

4 + 6 = 10

That gives us the sum, which is 10/10 aka 1 whole

your welcome :) (btw can u please give brainly?)

Answer:

2/5 + 6/10 = 1

Step-by-step explanation:

first let’s change 2/5 so it has the same denominator as 6/10.

2/5 * 2/2 = 4/10

now add

4/10 + 6/10 = 1

Answer: $30

Step-by-step explanation:

5 pairs of socks cost 12.50 you divide 12.50 by 5 and you how much each pair of socks cost which is 2.5 which is 2.50 each pair of socks is 2.50 so now you multiply 2.50 by 12 and you get $30

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

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:

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:

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: 8.4 or 8 2/5

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:

38 %

Step-by-step explanation:

45 + 17 is 62. Soif you add 38% + 62% you'll get 100% !

Step-by-step explanation:

y-9= -1/3(x-4)

y-9= -1/3x+4/3

y= -1/3x+31/3

to find a point:

y= -1/3(0)+31/3

y=31/3
