what is a bar plot, and what do the vertical lines on a bar plot represent?

Answer:

f(-2) = -28

Step-by-step explanation:

f(x) = 12x-4

Let x = -2

f(-2) = 12(-2) -4

Multiply

    = -24-4

Add

  = -28

Answer:

Depends on the range of x

Step-by-step explanation:

Does that make sense to you

Answer:

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Interval Notation: (−∞,∞)

Set-Builder Notation: {x|x∈R}

f(x) is continuous on (−∞,0).

The function is continuous.

Answer:

$187.50

Step-by-step explanation:

change 25% into a decimal: 0.25

the you will multiply:

0.25 × 750 = $187.50

Hey there!

2a + 4 = 3

ADD 4 to BOTH SIDES

2a + 4 - 4 = 3 - 4

CANCEL out: 4 - 4 because that gives you 1

KEEP: 3 - 4 because it helps solve for the a-value

2a = 3 - 4

3 - 4 = -1

2a = -1

DIVIDE 2 to BOTH SIDES

2a/2 = -1/2

CANCEL out: 2/2 because it gives you 1

KEEP: -1/2 because it gives you the value of the a-value

a = -1/2

SIMPLIFY IT!

Therefore, your answer is: a = -1/2

Good luck on your assignment and enjoy your day!

Answer:

The expression for the size of the largest jellyfish 1 × 108 • 2 × 10-8 meters.

Step-by-step explanation:

A jellyfish can be up to 1 × 108 times bigger than femtoplankton. Find the size of the largest jellyfish by multiplying the size of a femtoplankton by 1 × 108 times.

The size of a femtoplankton is 2 × 10-8 meter. That means the expression for the size of the largest jellyfish 1 × 108 • 2 × 10-8 meters.

Answer:

3km=3000m

Step-by-step explanation:

if 1 km=1000m,

3 km:     3 x 1000 = 3000m

Answer:

[tex]4(6x + 5) = 2x + 10 \\ 4 \times 6x + 4 \times 5 = 2x + 10 \\ 24x + 20 = 2x + 10 \\ 24x - 2x = 10 - 20 \\ 22x = - 10 \\ x = \frac{ - 10}{22} = \frac{ - 5}{11} \\ thank \: you[/tex]

Answer:

-5 / 11 or -0.455

Step-by-step explanation:

this is a very simple question that does not need much complexity about it

we have

4( 6x + 5 ) = 2x + 10

first of all, we open the bracket;

24x + 20 = 2x + 10

now, we have to collect like terms;

24x - 2x = 10 - 20

22x = -10

divide through by 22 to give us!

22x / 22 = -10 / 22

x = -5 / 11

therefore,

x = - 5 / 11

hope that helps

thank you

Step-by-step explanation:uhHoAnd ghiorioghiltihlgitrghile

let   −5x+2y=14   be [1]

&        y=3x+2    be [2]  

Finding the value of x

By substituting y in [2] for y in [1]

⇒  −5x + 2(3x+2) = 14         [expand the bracket]

⇒     -5x + 6x + 4 = 14         [subract 4 from both sides and simplify]

⇒                       x = 10

Finding the value of y

Since x =10, we can substitute value of x into [2]

⇒     y = 3(10) + 2

⇒     y = 32

Answer:

by congruency theorem <ACB= <DEB

so 5y-3=72

5y=72+3

5y=75

y=15⁰

Answer:

43.2

26.4

6

Step-by-step explanation:

so first if we know that the loger side's ratio is 6 we divided by 7.2

7.2 divided by 6 which is 1.2

so we mulitply the 5 by 1.2

so the shorter side is 6

6 x 7.2 = 43.2 is the area

14.4 + 12 = 26.4 is the perimeter

Answer:

x:(-1,0),(5,0)

y:(0,-2)

Answer:

see explanation

Step-by-step explanation:

The x- intercepts are where the graph crosses the x- axis

The graph crosses the x- axis at x = - 1 and x = 5 ← x- intercepts

The y- intercept is where the graph crosses the y- axis

The graph crosses the y- axis at - 2 ← y- intercept

Answer:

A∩B = 2,4

A-B = 1,3,5

sin (A+B) = sin(A)cos(B)+cos(A)sin(B)

Step-by-step explanation:

A intersects U means the numbers that are coming to both A and U

set a minus set b of the numbers that are not common to B

multiply the numerator and the denominator by csc(x)

NOTE: I substituted x for theta as I don't have theta on my phone

[tex] \frac{ \csc(x) }{ \csc(x)} \frac{ \tan(x) - \sin(x) }{ \tan(x) + \sin(x) } = \frac{ \sec(x) - 1}{ \sec(x) + 1} [/tex]

[tex] \frac {\csc(x)}{\csc(x)} \frac {\frac ({\sin(x)}{\cos(x)}-\sin(x)} {\frac ({\sin(x)}{\cos(x)} + \sin(x)}) [/tex]

Answer:

47 1/3 = 142 / 3      total clay

2 1/2 = 5 / 2      clay required for each student

If we divide total clay by clay per student

(142 / 3) / (5 / 2) = 284 / 15 = 18.9

So he should have enough clay for 18 students
