Answer:

6

Step-by-step explanation:

The only number that will equal 64 if it is the power of 2

Answer:

True

Step-by-step explanation:

Cuz if u substitute (3,-3/2) it would work

Y = 1/2x - 3

-3/2 = 1/2(3)-3

-3/2 = 1.5 - 3

-3/2 = -1.5

& -3/2 is -1.5 as a decimal lol

Answer:

When dividing two fractions, the process is very easy.  You simply multiply the numerator fraction by the reciprocal of the denominator fraction.  In other words:

[tex]\frac{a}{b} \div \frac{c}{d} \\= \frac{a}{b} \times \frac{d}{c} \\= \frac{a \times d}{b \times c}[/tex]

Step-by-step explanation:

In that equation it tells you that your slope is 2/3. It also tells you that your y intercept is -4. (Remember slope is written in y=mx+b) So first you plot your y value. (Remember that y intercept is up and down and slope is rise/fall over run) So your first point should be located at -4. Now you can began putting in your slope. Since your slope is positive, go up two and go to the right 3 times (rise/run). That's how you graph your equation.

So your answer is only [tex]\bold{(-2\frac{1}{3},\frac{1}{3})}[/tex].

Answer:

(-2,3)

Step-by-step explanation:

Given data

the system of linear equation is presented as

3x+5y=9-----1

2x+3y=5-----2

solve simultaneously

3x+5y=9-----1  X 2

2x+3y=5-----2  X3

subtracting 2 from 1

 6x+10y=18

-6x+9y=15

0x+y=3

y= 3

put y= 3 in 1

3x+5(3)=9-----1

3x+15=9

3x= 9-15

3x= -6

x= -6/3

x= -2

Hence the ordered pair is (-2,3)

expression:  (30/t) - 10

evaluation:  30/2 - 10 = 5

Step-by-step explanation:

9514 1404 393

Answer:

  105 minutes

Step-by-step explanation:

The volume of the terrarium is ...

  V = LWH

  V = (42 in)(10 in)(9 in) = 3780 in³

The volume of a box is ...

  V = (3 in)(3 in)(3 in) = 27 in³

Then the number of boxes it takes to fill the terrarium is ...

  (3780 in³)/(27 in³/box) = 140 boxes

The mermaid wants to fill it 3/4 full, so only needs 3/4 this number of boxes. That is 105 boxes. At the rate of 1 per minute, ...

  it will take 105 minutes to fill 3/4 of the terrarium

Answer:

Step-by-step explanation:

New price = (1 + 5%) x old price

New price = 1.05 x old price

old price = 2.3 / 1.05

Old price = £2.19

9514 1404 393

Answer:

  £46

Step-by-step explanation:

The increase is ...

  0.05 · price = £2.30

Multiplying by 20 gives ...

  price = 20(£2.30) = £46.00

The price of the ticket before the increase was £46.00.

Step-by-step explanation:

3x - 10 = 2 | Given

3x = 12 | Add 10 to both sides to isolate 3x

x = 4 | Divide both sides by 3 to get the value of x

Answer:

4

Step-by-step explanation:

3x - 10 = 2

add

3x = 12

divide

x = 4

Answer:

22

Answer:

Step-by-step explanation:

iF we have a normal distribution then the probability is 95.45%.

Answer:

Parallel lines have the same slope. Because the functions \displaystyle f\left(x\right)=2x+3f(x)=2x+3 and \displaystyle j\left(x\right)=2x - 6j(x)=2x−6 each have a slope of 2, they represent parallel lines. Perpendicular lines have negative reciprocal slopes. Because −2 and \displaystyle \frac{1}{2}

2

1

are negative reciprocals, the equations, \displaystyle g\left(x\right)=\frac{1}{2}x - 4g(x)=

1

x−4 and \displaystyle h\left(x\right)=-2x+2h(x)=−2x+2 represent perpendicular lines.

Answer:

Intercepting.

Step-by-step explanation:

The line x=10 is a straight vertical line going through all the points where x=10, as the equation suggests.

The line y=10 is a horizontal line going through all the points where y=10.

When you graph them, they intersect in a perfect cross.

Answer:

Step-by-step explanation:

The length of the subway is 900 miles.

So if 1 inch is 45....we want to find it for 900 miles

900/45 = 20

So it will be 20 inches for 900 miles

Check by using ratio

1 : 45

2 : 90

3 : 135

4 : 180

5 : 225

6 : 270

7 : 315

8 : 360

9 : 405

10 : 450

11 : 495

12 : 540

13 : 585

14 : 630

15 : 675

16 : 720

17 : 765

18 : 810

19 : 855

20 : 900

1 - 20 = inches

45 - 900 = miles

So for 900 miles, it will be 20 inches long

Answer:

[tex] \large \boxed{f(8) = 27}[/tex]

Step-by-step explanation:

Goal

Given

[tex]f(x) = \frac{1}{2} {x}^{2} - ( \frac{1}{4} x + 3)[/tex]

Step 1

[tex]f(8) = \frac{1}{2} {(8)}^{2} - ( \frac{1}{4} (8) + 3)[/tex]

Step 2

[tex]f(8) = \frac{1}{2} (64) - ( \frac{8}{4} + 3) \\ f(8) = 32 - ( \frac{2}{1} + 3) \\ f(8) = 32 - (2 + 3) \\ f(8) = 32 - (5) \longrightarrow 32 - 5 \\ f(8) = 27[/tex]

Hence, the value of f(8) is 27.
