Answer:

Graph A is a function, and Graph B is not

Step-by-step explanation:

A function is when each x-value (aka input) has 1 corresponding y-value (or output).

We see that graph 1 is linear, and that each x-value has it's own y-value, and not multiple y-values.

However, Graph B curves, making it so some of the x-values have more than 1 y-value.

Answer:

the inverse of a function is the exact opposite

Answer:

D)   f (-1) (x) = x³-12

Step-by-step explanation:

∛x+12                      

Interchange the variables and solve for y

∛y +12 =x

(∛x+12) ³= x³

y+12 = x³

y= x³-12

f (-1) (x) = x³-12

Answer:

In explanation.

Step-by-step explanation:

1. 5 x 2 =10

5 x 1=5

5 x 2=10

5 x 3=15

5 x 4=20

5 x 6=30

5 x  7=35

5 x 8=40

5 x 9=45

5 x 10=50 and since  5 x 10 is 50 and were looking for 100 a easy way to do that is 50 x 10 which=500 or another easy way is.

100 x 1=100

100 x 2=200

100 x 3=300

100 x 4=400

100 x 5=500

Hope this helps have a great day:)

Step-by-step explanation:

5x2=10

5x6=30

5x4=20

5x4=20

5x100=500

Answer:

Let the Width(W) = X cm

then the length(L)= (2+X)cm

Perimeter(P)= 60cm

P =L+W

L+W =P

(2+X)cm +X cm = 60 cm

2X+2=60

2X=60-2

2X=58

dividing both sides by 2

X=29cm

Width =X

Width =29cm

the width is 29cm

Length= (2+X)cm

= (2+29)cm

= 31cm

the length is 31cm

We will let w represent the width of the rectangle (in centimeters).

We know that the length is 2 cm longer than the width.

So the length is w + 2 .

We can label the rectangle as follows.

The perimeter is given as 60 cm.

So we solve for w as follows.

w + (w + 2) + w + (w + 2) = 60

w + w + 2 + w + w + 2 = 60

4w + 4 = 60

4w = 56

w = 14

Using this value of w, we can find w + 2.

w + 2 = 14 + 2 = 16

ANSWER

length: 16 cm

width: 14 cm

Answer:

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

Step-by-step explanation:

To put this equation into slope-intercept form, we need to isolate y on one side of the equation.

First, we should move 12x to the right side of the equation. To do this, we need to subtract 12x from both sides.

12x - 20y - 12x = -20y (12x and -12x cancel out)

60 - 12x

We are left with;

-20y = 60 - 12x

To isolate y, we need to divide all the terms by -20.

-20y/-20 = y

60/-20 = -3

12x/-20 = [tex]\frac{12}{20}x[/tex]

[tex]\frac{12}{20}[/tex] can be simplified to [tex]\frac{3}{5}[/tex]

So, the equation we are left with is;

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

Step-by-step explanation:

Let Justin's age be x

Arlene today is 1/4 x

Ten years from now

Arlene:  1/2 (x + 10) = 1/4 x + 10       Remove the brackets

1/2 x + 5 = 1/4x + 10                          Subtract 1/4x from both sides.

1/2 x - 1/4x + 5 = 10                           Combine

1/4x + 5 = 10                                      Subtract 5 from both side

1/4 x = 10 - 5                                      Combine

1/4 x = 5                                             Multiply both sides by 4

x = 5 * 4

x = 20

Arlene is 5 years old (1/4 20) right now

Answer:

80 lemons

Step-by-step explanation:

Let x represent the amount of lemons that were on the tree.

We can use this to set up an equation:

[tex]40\%x=32[/tex]

Note that percentages can also be written as that number over 100.

[tex]\frac{40}{100}x=32[/tex]

Simplify the fraction.

[tex]\frac{2}{5}x=32[/tex]

Multiply both sides by 5

[tex]2x=160[/tex]

Divide both sides by 2

[tex]x=80[/tex]

There were 80 lemons on the tree before he picked the lemons.
