The sum of two numbers is 59 and the difference is 21. What are the numbers?
Larger number:
Smaller number: 0
2.

Answer:

Step-by-step explanation:

9(c+7)=27

9c+63=27  subtract 63 from both sides

9c=  -36  divide by 9

c= -4

3(2r-8)+4r=76 foil

6r-24+4r=76 combine like terms

10r-24=76 add 24 to both sides

10r+100  divide by 10

r= 10

➤ How to solve ?

⠀⠀⠀⠀

That's quite easy but you need to recall the BODMAS rule .

⠀⠀⠀⠀

BODMAS rule states the correct sequence to solve an equation . First we need to solve the bracket part then solve if any of is present moving further to division then multiplication carrying with addition atlast subtraction

⠀⠀⠀⠀

In this equation we will solve the bracket then we will apply further BODMAS rule

SolutiOn :

➠ 7x + 31 = 8x - 1 ( 27x + 3 ) -3

➠ 7x + 31 = 8x - 27x - 3 - 3

Now, we will bring the variable on left hand side and constants on right hand side

➠ 7x - 8x + 27x = - 31 - 3 - 3

➠ 26x = -37

➠ x = -37/ 26

➠ x = - 1.42

∴ The value of x is -1.42 .

{} , {red}, {blue}, {pink}, {green} , {red, blue}, {red, pink}, {red, green}, {blue, pink} , {blue, green} , {pink, green}, {red, blue, pink}, {red, pink, green}, {blue, pink, green}, {red, blue, green}, {red, blue, pink, green}

Step-by-step explanation:

Given set is:

{red, blue, pink, green}

First of all, we have to calculate the number of subsets

In the given set,

n =  4

So the number of subsets will be: 2^4 = 16

The subsets are:

{} , {red}, {blue}, {pink}, {green} , {red, blue}, {red, pink}, {red, green}, {blue, pink} , {blue, green} , {pink, green}, {red, blue, pink}, {red, pink, green}, {blue, pink, green}, {red, blue, green}, {red, blue, pink, green}

Step-by-step explanation:

Answer:

-1/27

Step-by-step explanation:

Opposite rays are two rays that both start from a common point and go off in exactly opposite directions. Because of this the two rays (QA and QB in the figure above) form a single straight line through the common endpoint Q. When the two rays are opposite, the points A,Q and B are collinear.

Step-by-step explanation:

y = 2x

y = x + 1

y-1 = x

y = 2x

y = 2 (y - 1)

y = 2y - 1

y = -1

the opposite or addictive increase of 5x is -5x.

the opposite or addictive increase of 5x + 8 is -5x -8.

Answer:

Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x5+85 f - 1 ( x ) = x 5 + 8 5 is the inverse of f(x)=5x−8 f ( x ) = 5 x - 8 .

Answer:

f(x)= 4x+3, if x<-1

f(x)= -x, if x[tex]\geq[/tex]-1

x+5y=8... equ 1

-x+2y=-1 ..... equ2

Add equ 1 to equ 2

0x+7y=7

7y=7

Y=1

Subsitute the value of y in equ 1 or equ 2

By subsituting In equ 1

X+5(1)=8

X=3

wow that's a lot lol

1. slope = 0

2. slope = -5

3. slope = 5

4. slope = 0

5. slope=  -1

6. slope = -1/2

7. slope = 3

8. slope = -1/10

9. slope = 1/2

10. slope = -1/2

Explanation :

I won't explain every question because that'll take forever but I can explain one step by step.

An example is number 5

You have the points, ( -4 , 5 ) ( 1 , 0 )

You need to use the SLOPE FORMULA

So first put an x1 and y1 below the points -4 and 5.

then put x2 and y2 below the points 1 and 0

the slope formula is   m = y2-y1/x2-x1

plug in the numbers which will look like

0-5/1+4

It's plus 4 instead of -4 because a negative and negatives gives you a postivie

Simplify and you get m = -1

Answer:

D. [tex] \frac{1}{4} [/tex]

Step-by-step explanation:

Rectangle VWXY after dilation, became compressed to rectangle V'W'X'Y'.

This makes both rectangles similar. It follows that the corresponding side lengths or segments of both figure would be proportional. Thus, the scale factor of the dilation would be:

[tex] \frac{W'X'}{WX} [/tex]

W'X' = 5

WX = 20

Plug in the values

[tex] \frac{5}{20} [/tex]

Simplify

[tex] scale factor = \frac{1}{4} [/tex]

Answer:

x-intercept(s): (3,0)

y-intercept(s): (0,−2)

Step-by-step explanation:

Answer:

x=3 and y=-2

Step-by-step explanation:

2x - 3y = 6

cancel out the y

2x - 3(0) = 6

2x = 6

divide both sides by 2

x = 3

2x - 3y = 6

cancel out the x

2(0) - 3y = 6

-3y = 6

divide both sides by -3

y = -2

Step-by-step explanation:

Answer:

20.62 feet

Step-by-step explanation:

The ladder propped against a building forms a right angle triangle

Height of the ladder (hypotenuse) = 21 feet

Base of the ladder from the building (adjacent) = 4 feet

Height of the building (opposite) = x feet

Hypotenuse ² = opposite ² + adjacent ²

21² = x² + 4²

21² - 4² = x²

441 - 16 = x²

425 = x²

x = √425

= 20.62 feet

Answer: 20.62 ft or rounding it to 20.6 ft
