Please check the explanation.

Step-by-step explanation:

The slope-intercept form of the linear function  

[tex]y = mx+b[/tex]

where

The graph of y = mx + b is a straight line. Thus, y = mx + b represents a linear function.

Analzing the function y = –x + 5

Given the linear function

y = –x + 5

comparing with the slope-intercept form of linear equation

The slope m = -1

The y-intercept b = 5

Also, the graph of a linear function is a straight line.

Thus,

The function  y = –x + 5 represents  a linear function.

Analzing the Table Function

x        0     1     2     3

y        0     1     8     27

In order to identify whether the given table represents the linear function or not, we need to make sure the given function has a constant change x and y.

If there is a constant change in x and y, then it would be a linear Function otherwise it would not represent a linear function.

There is a constant change in x values.

i.e.

1 - 0 = 1

2 - 1 = 1

3 - 2 = 1

But, there is NOT a constant change in y.

i.e.

1 - 0 = 0

8 - 1 = 7

27 - 8 = 19

It is clear that the table does not have a constant change in y-values.

Therefore, the table function does not represent the linear function

Step-by-step explanation:

let jon age be x

dad age is 2 of x i.e 2x

grandpa age is 7 + 3(x)

The sum of jon dad and grandpa age is 145 i.e

x + 2x + (7+3x) = 145

3x +. 7 + 3x = 145

6x = 145- 7

6x = 138

divide both sides by 6

x = 23

jon age is 23

while

grandpa age is

7 + 3(x)

7 + 3(23)

7 + 69

76.

Step-by-step explanation:

hey! keep calm okay? i got u.

Okay so for a pack of 12 confetti eggs, you pay $2.88. to find the unit price, or price for 1 egg, you just take 2.88 divided by 12 (which i already did) and you get 0.24. so the price for 1 confetti egg is $0.24 or 24 cents.

James reads 520 words in 2 minutes. Luke reads 960 words in 5 minutes. All we need to find out is how many words can they read in 1 minute? All ewe do is take 520 divided by 2, and you get 260. Then you take 960 divided by 5, and you get 192. so the rates they read at is 260 wpm and 192 wpm.

A shipping and handling fee is 35.00 right? so what you want to find is “35.00 is what percent of 437.50?” and if you think about it and go through it, 35 is 8% of 437.50. so 8% of the total is the shipping and handling fee!

good luck! i hope this helped!

Answer:

x=-7

Step-by-step explanation:

Alrighty. 5x+8=2x-13. Lets do -2x on both sides. We'll get 3x+8=-13. Then lets subtract 8 from both sides. We'll get 3x=-21. Divide by 3 and we'll get x=-7. Hope that makes sense.

Answer:

575 mm

Step-by-step explanation:

The ratio of perimeters is the same as the ratio of sides.

let x be the perimeter of B then by proportion

[tex]\frac{3}{345}[/tex] = [tex]\frac{5}{x}[/tex] ( cross- multiply )

3x = 1725 ( divide both sides by 3 )

x = 575

Then the perimeter of B is 575 mm

Answer:

-5.4 + 2.52h

Step-by-step explanation:

The solution to the equation y = 5x - 5 is given by the ordered pairs

( 0 , -5 ) , ( 1 , 0 ) , ( 2 , 5 ) , ( 3 , 10 ) , ( 4 , 15 )

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

y = 5x - 5   be equation (1)

On simplifying the equation , we get

Substitute the value of x = 0 in the equation , we get

y = 5 ( 0 ) - 5

y = 0 - 5

y = -5

So , the ordered pair is ( 0 , -5 )

Substitute the value of x = 1 in the equation , we get

y = 5 ( 1 ) - 5

y = 5 - 5

y = 0

So , the ordered pair is ( 1 , 0 )

Substitute the value of x = 2 in the equation , we get

y = 5 ( 2) - 5

y = 10 - 5

y = 5

So , the ordered pair is ( 2 , 5 )

Substitute the value of x = 3 in the equation , we get

y = 5 ( 3 ) - 5

y = 15 - 5

y = 10

So , the ordered pair is ( 3 , 10 )

Substitute the value of x = 4 in the equation , we get

y = 5 ( 4 ) - 5

y = 20 - 5

y = 15

So , the ordered pair is ( 4 , 15 )

Hence , the equations are solved

Answer:

root3/ root2

Step-by-step explanation:

since this is a special right triangle (45, 45, 90) we can use right triangle rules. Basically, C in my photo is equal to the hypotenuse while A and B are equal to the sides. You can substitute your hypotenuse into the formula I gave you to find x.

B = C / root2

x = root3 / root2

Answer:

let the two number be x and y then,

x+y=12

x-y=-4

-----------

2x=8

or, x = 4 put the value of x in first equation

4+y= 12

or, y=12-4

or, y= 8 hence the two number is 4 and 8
