This is how to calculate net price. Start with the list price and add any taxes and other government-mandated charges. Then subtract any discounts, negotiated prices. The result you get will be the net price.

Answer:

y=7.5x-2

Step-by-step explanation:

m is the gradient of the line so it has to be positive for a positive slope

c is the y intercept so it has to be negative for a negative y intercept

The number of cookies Zahra made with 4/5 kilograms of butter is 1333.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, Zahra has 4/5 kilograms of butter to bake cookies.

Each batch of cookies requires 6/10 grams of butter

4/5 kilograms = 800 grams and 6/10 grams =0.6 grams

Number of cookies = Number of kilograms of butter ÷ Butter requires in each cookie

= 800 ÷ 0.6

= 800/0.6

= 1333

Therefore, the number of cookies are 1333.

Answer:

10, 20, 5

Step-by-step explanation:

she's selling 1 bag for 10 dollars

The first row says 1 bag, that is 10 dollars so the answer is 10

The second row says 2 bags, so you just do 10 times 2. This is 20

The third row gives you the amount of money instead. Since they are 10 dollars each, 50 dollars means 5 bags of churros. I just did 50 divided by 10 to get 5 :)

(1/2)x - 4y = -1 is the necessary equation, and A = 1/2 is the value of the missing coefficient of the equation Ax - 4y = -1

The definition of an equation is a mathematical statement with at least two terms that contain variables or equal numbers.

According to the Given information

An equation has been provided to us as

Ax - 4y = -1 ...... (i)

The answer is given at point (6,1),

Replace the values of x = 6 and y = 1 in the equation above,

A(6) - 4(1) = -1

A×6 -4 = -1 (+4)

A×6 = 3 / 6

In the equation above, decrease the fraction.

A = 1/2

Replace A = 1/2 with its value in the equation (i),

So (1/2)x - 4y = -1

As a result, (1/2)x - 4y = -1 is the necessary equation, and A = 1/2 is the value of the missing coefficient of the equation Ax - 4y = -1

Answer:

b 25 i think

Step-by-step explanation:

It depends on the type of function, however there are patterns that can be found

A general rule of thumb to consider is as follows

f(x) + d shifts a function up d units

f(x) - d shifts a function down  d units

Ex. [tex]f(x) = x^{2} +3[/tex] shifts up 3 units, and [tex]f(x) = 2x - 4[/tex] shifts down four units

f(x+c) shifts a function left c units

f(x-c) shifts a function right c units

EX. [tex]f(x) = (x+2)^{2}[/tex] shifts left 2 units, and [tex]f(x) =(x-7)^{2}[/tex] shifts right 7 units

-f(x) is a reflection over the x-axis

EX. [tex]f(x) = x^{2}[/tex] opens up, while [tex]f(x) = -x^{2}[/tex] opens down

These guidelines can also be combined

EX. [tex]f(x) = -(x-4)^{2} + 3[/tex] opens down, is shifted right 4 units, and is shifted up 3 units from the parent function

Answer:

x = 3

This equation has only one solution.  The only number that will make both sides of the equation equal is 3.

Step-by-step explanation:

2(4x -3) -8 = 4 + 2x  Distribute the 2

8x -6 -8 = 4 + 2x  Combine like terms

8x -14 = 4 + 2x  Subtract 2x from both sides S(Subtraction property of equality)

6x - 14 = 4  Add 14 to both sides (subtraction property of equality)

6x = 18  Divide both sides by 6 (division property of equality)

x = 3

Check:

2[4(3) - 3] - 8 = 4 + 2(3)

2(12 - 3) - 8 = 4 + 6

2(9) - 8 = 10

18 - 8 = 10

10 = 10

Answer:7

Step-by-step explanation:

The value of x that makes the inequality true is: D. √0.02.

If we are given an inequality statement, the value of the variable of the inequality must be such that makes the statement true, which is the possible set of values of the variable.

Given that 1/8 < x < 18%, note the following:

1/8 = 0.125

18% = 0.18

This means that, 0.125 must be less than the value of x, while the value of x must be less than the value of 0.18, for the inequality to be true.

Considering the options given, 1/5 = 0.2. 0.2 is greater than 0.18 (18%).

1.6 is also greater than 0.18 (18%) and 1/8 (0.125).

1/8(0.125) is greater than 0.09.

Thus, √0.02 is approximately 0.14.

1/8 (0.125) < 0.14 < 18% (0.18). Therefore the value of x would be: D. √0.02.

Answer:

J = $1740.99

I = $1302.52

Step-by-step explanation:

1) Write Equations

I + J = 3043.51

I + 438.47 = J

Where I = amount paid by Isabella and J = amount paid by Jesus

Thus by substituting I + 438.47 for J the equation becomes,

I + I + 438.47 = 3043.51

Combining like terms gives the final equation

2I + 438.47 = 3043.51

2) Solve the final Equation to find how much Isabella paid

2I + 438.47 = 3043.51

2I + 438.47 - 438.47 = 3043.51 - 438.47

2I = 2605.04

2I/2 = 2605.04/2

I = 1302.52

3) Then use the Third Equation to solve how much Jesus paid

I + 438.47 = J

(1302.52) + 438.47 = J

1740.99 = J

The irregular polygon has an area of 300 square inches.

Herein we find an irregular pentagon shown in the figure, whose area has to be found. This can be done by considering it a composite figure, whose area is the sum of areas of triangles and rectangles.

In that sense, the area of the irregular polygon is the sum of the areas of two triangles and a rectangles, whose formulas are shown below:

Triangle

A = 0.5 · b · h

Where:

Rectangle

A = b · h

Now we proceed to determine the area of the irregular polygon:

In the given options, none of them have inequality sign ≤ and ≥,  so the given inequalities do not have solid line in its solution graph.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

A solution for an inequality in x is a number such that when we substitute that number for x we have a true statement.

The boundary line for the inequality is drawn as a solid line if the points on the line itself do satisfy the inequality, as in the cases of ≤ and ≥. It is drawn as a dashed line if the points on the line do not satisfy the inequality, as in the cases of < and >.

The dilation rule applied to quadrilateral ABCD is (1.5x, 1.5y)

What is the Dilation?

Math definition of dilation Resizing an object is accomplished through a change called dilation. The objects can be enlarged or shrunk via dilation. A shape identical to the source image is created by this transformation. The size of the form does, however, differ.

Using C' and C as points of references,

C' = (4,4)

C = (6,6)

The dilation factor (k) is calculated as:

k= C/C' = (6,6)/ (4,4)

Factorize:

k = [3(2,2)] / [2(2,2)]  = 1.5

Hence, the scale factor is 1.5

The dilation rule is:

(x,y) => k (x,y)

(x,y) => 1.5 (x,y)

(x,y) => (1.5x, 1.5y)

The corresponding sides of two triangles are proportionate if they are identical then the length of side ZX exists 10.5 units.

What is meant by right triangles?

If one of the triangle's angles is 90 degrees, the triangle is said to be right-angled. 90 degrees is the sum of the other two angles. Perpendicular and the triangle's base make up the sides that the right angle is formed from. The hypotenuse, or third side, is the longest of the three. It is also known as the hypotenuse.

Main body:

If two triangles are similar, then their corresponding sides are proportional.

Since , therefore

AB/X Y = BC/YZ = CA/ZX

substitute the values in the above equation, we get

2/7 = 4/14 = 3/N

2/7 = 2/7 = 3/N

2/7 = 3/N

On cross multiplication, we get

2 × N = 3 × 7

2N = 21

Divide both sides by 2

N = 21/2

N = 10.5
