84/12=7x3=21

Answer:

x=-2 and y =0

Step-by-step explanation:

2x + 3y=-4

y=2x + 4

2x -y = -4

4y= 0

y = 0

2x -0=-4

Answer:

70 + 95 = 5(14 + 19)

70 + 95 = 5(14 + 19)

gcf = 5

Step-by-step explanation:

70+95

70=2*5*7

95=5*19

70+95=(5*2*7)+(5*19)=(5*14)+(5*19)=5*(14+19)=5*(33)

5*33=165 and 70+95=165                                                                                                  Hope this helps! Please give me brainly!      

Answer:

h= -21.2

Step-by-step explanation:

Subtract 10.6 from both sides to isolate the h

Now lets check the answer

-21.2 + 10.6 = -10.6

-10.6 = -10.6 ✅

Answer:

option D

Step-by-step explanation:

diameter of two small circle i.e 14cm

radius of two small circle =7cm

area of the small circle =πr²

area of the small circle=22/7 x7²

area of the small circle=154cm²

Area of bigger circle=22/7×14²

Area of bigger circle=616cm²

Area of shaded region =area of bigger circle -area of small circle +area of small circle

area of shaded region =616-154+154

area of shaded region=308cm²

i.e approximately 282.74cm²

Answer:

A. Homes using solar power always have lower utility bills than homes using only gas and electricity.

Step-by-step explanation:

Gas and Electricity

[tex]\bar x = 93[/tex]

[tex]\sigma = 11[/tex]

Solar

Bills: 56, 54 and 51

Required

Determine which of the statements is true

First, we calculate the mean of the given data

[tex]\bar x = \frac{\sum x}{n}[/tex]

[tex]\bar x = \frac{56 + 54 + 51}{3}[/tex]

[tex]\bar x = \frac{161}{3}[/tex]

[tex]\bar x = 53.67[/tex]

Then, the standard deviation

[tex]\sigma = \sqrt{\frac{\sum(x - x_i)^2}{n}}[/tex]

[tex]\sigma = \sqrt{\frac{(56 - 53.67)^2 + (54 - 53.67)^2 + (51 - 53.67)^2}{3}}[/tex]

[tex]\sigma = \sqrt{\frac{12.67}{3}}[/tex]

[tex]\sigma = \sqrt{4.223}[/tex]

[tex]\sigma = 2.05[/tex]

So, we have:

Gas or Electricity

[tex]\bar x = 93[/tex]

[tex]\sigma = 11[/tex]

Solar

[tex]\bar x = 53.67[/tex]

[tex]\sigma = 2.05[/tex]

By comparison.

The mean and standard deviation of homes using solar panel is less than home using gas and electricity.

This implies that: (a) is true.

A change in demand means that the entire demand curve shifts either left or right. A change in quantity demanded refers to a movement along the demand curve, which is caused only by a chance in price.

Answer:

[tex]f^{-1}(x) = \sqrt[3]{\frac{x -4}{5}} +2[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 5(x - 2)^3 + 4[/tex]

Required

Determine the inverse

[tex]f(x) = 5(x - 2)^3 + 4[/tex]

Replace f(x) with y

[tex]y = 5(x - 2)^3 + 4[/tex]

Swap the positions of x and y

[tex]x = 5(y - 2)^3 + 4[/tex]

Make y the subject

[tex]x -4= 5(y - 2)^3[/tex]

Divide by 5

[tex]\frac{x -4}{5}= (y - 2)^3[/tex]

Take cube roots of both sides

[tex]\sqrt[3]{\frac{x -4}{5}}= y - 2[/tex]

Add 2 to both sides

[tex]\sqrt[3]{\frac{x -4}{5}} +2 = y[/tex]

[tex]y = \sqrt[3]{\frac{x -4}{5}} +2[/tex]

Replace y with [tex]f^{-1}(x)[/tex]

[tex]f^{-1}(x) = \sqrt[3]{\frac{x -4}{5}} +2[/tex]

Answer:

A taco cost $1 while a burrito cost $1.79

Step-by-step explanation:

This may be computed as a set of simultaneous equations

Thelma ordered 2 tacos and 1 burrito and paid $ 3.79

let the cost of a taco be t and a burrito b then

2t + b = 3.79

Louise ordered 2 burritos and 1 taco and paid . \$4.58​

t + 2b = 4.58

solve both equations simultaneously

multiply the first by 2

4t + 2b = 7.58

t + 2b = 4.58

subtract 2 from 1

3t = 3

t = 1

t + 2b = 4.58

1 + 2b = 4.58

2b = 4.58 - 1

2b = 3.58

Divide both sides by 2

b = 1.79

A taco cost $1 while a burrito cost $1.79
