Show the steps of solving. a) 6x - 2y = 28
4x + 2y = 12

PLEASE HELPPPPP I’ll give brainlist!!!

Answers

Answer 1

Answer:

x = 4 and y = -2

Step-by-step explanation:

Let 6x - 2y = 28 be equation (i)

and 4x + 2y = 12 be equation (ii)

To solve the following equations, first add the equations:

6x - 2y + 4x + 2y = 28 + 12

6x + 4x + 2y - 2y = 28 + 12

10 x = 40

x = 4

Substituting in (ii)

4x + 2y = 12

4*4 + 2y = 12

2y = 12 - 16

2y = -4

y = -2

Given the equation 3x+4y=20, is the point (4,2) a solution to the equation? Explain and

Answers

Answer:

(4, 2) is a solution to the equation

Step-by-step explanation:

if y = 2 and x = 4 add fill them into the equation

3(4) + 4(2) = 20

12 + 8 = 20

20 = 20

this makes the equation true

So yes, (4, 2) is a solution to the equation.

the sum of two consecutive integers is three times their difference.what is the larger number.please help!​

Answers

9514 1404 393

Answer:

  2

Step-by-step explanation:

If n is the larger integer, n-1 is the smaller. The difference of consecutive integers is 1, so their sum is ...

  n +(n -1) = 3(1)

  2n = 4 . . . . . . . . . add 1

  n = 2 . . . . . . . . . . divide by 2

The larger integer is 2.

Answer:

2

Step-by-step explanation:

The larger number r={2}

PREMISES

r+s=3(r-s)

ASSUMPTIONS

Let r=s+1

Let s=s

CALCULATIONS

(s+1)+s=3[(s+1)-s]

2s+1=3[(s-s)+1]

2s+1=3(0+1)

2s+1=3(1)

2s+1=3

2s+(1–1)=3–1

2s+0=3–1

2s=2

2s/2=2/2

s=2/2

s=

{1}

And if s=1, then

r=s+1=

{2}

PROOF

If r, s={2,1}, then the equations

(1) r+s=3(r-s)

(2) 2+1=3(2–1)

(3) 2+1=3(1) and

(4) 3=3 prove the roots (zeroes) r, s={2,1} of the statement r+s=3(r-s)

Ms. Rogers bought 4 bags of candies to make gift boxes for her family. Each bag contained 18 candies. She put an equal number of these candies into each of 7 gift boxes. How many candies were left over?

Answers

Answer:

2 candies were left.

Step-by-step explanation:

Number of bags of candies = 4 bags

Number of candies in each bag = 18 candies

Total number of candies = [tex]4(18)=72[/tex]

Ms. Rogers put an equal number of these candies into each of 7 gift boxes.

Divide 72 by 7

72 = 7(10) + 2

Here, remainder is 2.

So,

2 candies were left.

Answer:

A. g(x) = 4.2%

Step-by-step explanation:

If you vertically stretch the exponential function f(x) = 2* by a factor of 4, what

is the equation of the new function?

A. g(x) = 4.2%

B. g(x) = 24

C. g(x) = . 2*

D. g(x) = 2 .4*

im not sure

The vertical stretch of the transformation of the function is g ( x ) = 4 ( 2 )ˣ

How does the transformation of a function happen?

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = 2ˣ

Now , the vertical stretch of a factor of 4 is given by

The transformed function is g ( x )

g ( x ) = 4 f ( x )

On simplifying , we get

g ( x ) = 4 ( 2 )ˣ

Hence , the transformed function is g ( x ) = 4 ( 2 )ˣ

Answers

Answer:

h = [tex]\sqrt{84}[/tex] cm

Step-by-step explanation:

The radius, height h and slant height form a right triangle.

radius r = 8 ÷ 2 = 4, hypotenuse = 10

Using Pythagoras' identity in the right triangle

h² + 4² = 10²

h² + 16 = 100 ( subtract 16 from both sides )

h² = 84 ( take the square root of both sides )

h = [tex]\sqrt{84}[/tex] cm
