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

Explanation:

T = (0,0) moves to T ' = (3,0) since we shift 3 units to the right. We add 3 to the x coordinate. The y coordinate does not change since we're not shifting up or down.

Q = (-2,0) moves to Q ' = (1,0) after applying the same rule we did to point T.

M = (-3,2) moves to M ' = (0,2)

Y = (-3,3) moves to Y ' = (0,3)

See the diagram below

Answer:

(64x -11)/y

Step-by-step explanation:

Multiply 4x into the parenthesis.

60x + 4xy -11y

Divide by y.

(60x + 4x -11)/y

(64x -11)/y

Steps to solve:

4x + (15x + y) - 11y​

~Remove parenthesis and combine like terms

4x + 15x + y - 11y​

19x - 10y

Answer:

80y-24z

Step-by-step explanation:

Answer:

Step-by-step explanation:

To calculate either the profit or loss we must first find the cost price and the selling price

For the cost price

She bought 150 oranges at ¢12

Cost price = ¢ 12.00

For the selling price

She sold 6 at 30 Gp that's ¢ 0.30

If she sold 6 at ¢ 0.30

Then 150 will be 150× 0.3/ 6

Selling price = ¢ 7.50

Since the cost price is higher than the selling price she made a loss

Loss = Cost price - Selling price

Loss = ¢ 12 - ¢ 7.50

Hope this helps you

Answer:

a. P= 5000( 1.016)^x

b. $ 6344.18

Step-by-step explanation:

The equation for finding the compound interest annually is

P = P_1 ( 1 +r)^t

Here

P = the amount after the interest has been added or the new balance

P_1= the principal amount

r= rate at which interest is charged

t= time in years

So we have

P = the new balance

P_1= the principal amount= $ 5000

r= rate at which interest is charged= 1.6 %

t= time in years= x

Putting the values in the above equation

P = P_1 ( 1 +r)^t

P = 5000 ( 1+ 1.6/100) ^x

P= 5000( 1.016)^x

b) When t= 15

Again

Putting the values in the above equation

P = P_1 ( 1 +r)^t

P = 5000 ( 1+ 1.6/100)^15

P = 5000( 1.26883637) = 6344.18185= $ 6344.18

Answer:

b) −3y2−2x+1

d) −4xy+4y2−y−10

Step-by-step explanation:

b) -4x + y2 - 9 + 10 - x + 3x - 4y2

(i have just underlined, italic and made it bold to show the like terms)

-4x - x + 3x = -2x

y2 - 4y2 = -3y2

-9 + 10 = 1

-2x - 3y2 + 1

d) 0 - 20 - 5xy + 4y2 + 10 - y + xy

(i have just underlined, italic and made it bold to show the like terms, however the '-y' and '4y2' have no like terms)

0 - 20 + 10 = - 10

-5xy + xy = - 4xy

-10-4xy+4y2-y

Answer:

Please find attached the required inverse of a function chart

Step-by-step explanation:

The inverse of a function is found by reversing the operations of the  function

The inverse of the function f(x) = 2·x - 4 is found as follows;

x = 2·x - 4

x + 4 = 2·x

x = (x + 4)/2 = x/2 + 2

Therefore, the inverse of the function f(x) = 2·x - 4 is f(x) = x/2 + 2

The inverse function is plotted by generating data points as follows;

[tex]{}[/tex]x         [tex]{}[/tex]          f(x)

0                2

1                  2.5

Step-by-step explanation:

If we have 3 pizzas, each cut into slices of [tex]\frac{1}{4}[/tex], then we have a total of [tex]3 \div \frac{1}{4} = 3\cdot\frac{4}{1} = 12[/tex] slices.

This means that 12 friends can share the 3 pizzas.

Answer:

[tex]\frac{3}{8}[/tex]

[tex]2\times \frac{3}{8} = \frac{3}{4}[/tex]

Step-by-step explanation:

According to the given scenario given that

if Ali uses [tex]\frac{3}{8}[/tex]  of 2 pounds of clay for a game of 4 bowls

[tex]\frac{3}{8} (2) = \frac{6}{8} = \frac{3}{4}[/tex]

here Ali will use the number of pounds of clay to create a game

[tex]2\times \frac{3}{8} = \frac{3}{4}[/tex]

Now, we need to compute the number of pounds of clay that should be used in every bowl, we need to divide the prior outcome by 4 which is

[tex]\frac{2\times \frac{3}{8}}{4}[/tex]

Answer:

(a) N{A∩B} = 0

(b) N{A∪B} = 9

Step-by-step explanation:

Union of two sets: This can be defined as the sum of all the elements of the two sets without writing one element twice. it is denoted by the symbol ∪

Intersection of two sets; This is the set of elements that appears in both sets. It is denoted by the symbol ∩

From the question above,

assuming there is no repetition element in both set,

(a) The smallest number possible for N{A∩B} = 0

(b) The largest number possible for N{A∪B} = 4+5 = 9.

Answer:

Hey, you don't include any points, but I can give you the rule for an 180 degree rotation.

You just need to write the same points, but negative. So going from (x,y) to

(-x,-y).

As an example let's say you wanted to rotate (3,-4) 180 degrees about the origin. The the point after the rotation would be (-3,4).

Hope that helps!

The result is 5.

The verbal sentence to represent the equation would be:

The sum of a number and three quarters is five.

Answer:

-9 >= x

Step-by-step explanation:

5x + 1 <= 3x - 17

add 17 to both sides- that will cancel the one on the right side. And on left side it would add to 18

5x + 18 <= 3x

then subtract 5x from both sides- that will cancel the one on left side. And on the right side ur left with negative 2x

18 <= -2x

divide both sides by negative 2... since dividing by -2 u have to slip the inequality sign.

-9 => x

hi

5x+1 ≤ 3x-17

5x-3x≤ -17 -1

2x≤ -18

x≤  -18/2

x≤ -9

Answer:

n = -1

Step-by-step explanation:

1 - 8n - 8 = -7n - 6n - 12

Simplify

-8n - 7 = -13n - 12

Add 7 to both sides

-8n = -13n - 5

Add 13n to both sides

5n = -5

Divide both sides by 5

n = -1

Answer:

n = 1

Step-by-step explanation:

1 - 8n - 8 = -7n - 6n - 12

-8n + 7n + 6n = -12 + 8 - 1

5n = -5

n = -5/5

n = -1

probe:

1 - 8*-1 - 8 = -7*-1 - 6*-1 - 12

1 + 8 - 8 = 7 + 6 - 12 = 1

Answer:

351.48cm²

Step-by-step explanation:

Heron’s Formula

Find half the perimeter (30+30+26)/2=43

It’s the square root of each side subtracted from 43, multiplied together, times 43.

√(43-30)*(43-30)*(43-26)*43=√13*13*17*43=√=123539=351.481cm²

Area of triangle is, 351. 39 cm²

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

All the sides of triangles are,

⇒ 30 cm, 30 cm, and 26 cm

We know that;

⇒ Area of triangle = √ s (s - a) (s - b) (s - c)

Where, 's' is the semi perimeter of the triangle, and a, b and c are three sides of triangle.

Here, Sides are,

⇒ a = 30

⇒ b = 30

⇒ c = 26

Hence, We get;

⇒ s = (a + b + c) / 2

⇒ s = (30 + 30 + 26) / 2

⇒ s = 86 / 2

⇒ s = 43 cm

So, The area of triangle is,

⇒ Area of triangle = √ s (s - a) (s - b) (s - c)

⇒ Area of triangle = √ 43 (43 - 30) (43 - 30) (43 - 26)

⇒ Area of triangle = √ 43 × 13 × 13 × 17

⇒ Area of triangle = 13 √ 731

⇒ Area of triangle = 13 × 27.03

⇒ Area of triangle = 351. 39 cm²

Answer:

Blueberry costs 9 dollars

Pumpkin costs 7 dollars

Step-by-step explanation:

Let "b" represent the price of a blueberry pie

Let "p" represent the price of a pumpkin pie

Step 1: Set equation

5b + 12p = 143 ----- 1

10b + 8p = 142 ----- 2

Step 2:  Isolate 1 for "b"

5b = 143 - 12p

[tex]b = \frac{143}{5}-\frac{12}{5}p[/tex]  ------- 3

Step 3: Substitute 3 into 2

[tex]10(\frac{143}{5}-\frac{12}{5} p )+8p=142\\286 - 24p + 8p = 142\\-24p + 8p = 142 - 286\\-16p = -144\\p = -\frac{144}{-16}\\ p = 9[/tex]

Step 4: Subsitute p = 9 into 1 for b

[tex]5p + 12(9) = 143\\5p + 108 = 143\\5p = 143 - 108\\5p = 35\\\frac{5p}{5}=\frac{35}{5}\\p = 7[/tex]

Therefore a pumpkin pie costs 7 dollars while a blueberry pie costs 9 dollars

Answer:

540

Step-by-step explanation:

since that the first is 14+19 and they are just adding 4+9 which is 13 so, the last is just a 3, and 1+1 is 2, plus the 1 that we have from the 13, then, you just add 1 on the Middle.

With 25+13 also you add normally, just add a 2 on the middle. And With the 3rd one add a 3 on the middle. So, with the last one, you add a 4 too.

Answer:

10 shoes

Step-by-step explanation:

Step 1: State what is known

Giles has 10 socks for every 5 pairs of shoes

He has 20 socks

Step 2: Set up the ratio

Let 'x' represent how much shoes Giles has

10 socks : 5 shoes

20 socks : x shoes

Step 3: Convert ratio into fraction

[tex]\frac{Socks}{Shoes}[/tex]

10 socks : 5 shoes = [tex]\frac{10}{5}[/tex]

20 socks : x shoes = [tex]\frac{20}{x}[/tex]

Step 4: Set ratio equal to each other and solve

[tex]\frac{10}{5}=\frac{20}{x}\\ 10x = 100\\\frac{10x}{10}=\frac{100}{10}\\x = 10[/tex]

Therefore Giles has 10 shoes when he has 20 socks

Answer:

(f o g)(x) = [tex]\frac{4x+13}{4x+12}[/tex]

Domain : (-∞, -3) ∪ (-3, ∞)

Step-by-step explanation:

Given : f(x) = [tex]\frac{x-4}{x-5}[/tex]

            g(x) = 4x + 17

We have to find the value of (f o g)(x).

Since (f o g)(x) = f[g(x)]

                        = [tex]\frac{(4x+17)-4}{(4x+17)-5}[/tex]

                        = [tex]\frac{4x+13}{4x+12}[/tex]

For the Domain of the function (f o g)(x),

Given function is defined for (4x + 12) ≠ 0

4x ≠ -12

x ≠ -3

Therefore, Domain of the function will be : (-∞, -3) ∪ (-3, ∞)
