Please help me with this homework

Answer:

Are there two you're asking for?

#2: x ≥ 9

#3: x > -2

Step-by-step explanation:

#2 Work:

x - 13 ≥ -4

Step 1: Add 13 to both sides

x - 13 + 13 ≥ -4 + 13

Add -4 and 13 to get 9.

x ≥ 9

#3 Work:

x/2 > -1

Multiply both sides by 2. Since 2 is positive, the inequality direction remains the same

x/2 * 2 > -1 * 2

x > -2

Answer:

This function doesn't have zeros because it doesn't touch the x-axis.

EDIT: I didn't see the negative sign before the 3. The function crosses the x-axis at (-5,0) and (5,0). Sorry!

Answer:

he could invite 19 friends

Step-by-step explanation:

125 (buget) - 30 (cost for 1st ticket) = 95

95/5 = 19

Answer:

1. h = 2.4t + 4

2. 4 feet

3. 220 feet

Step-by-step explanation:

1. Write a linear model for the height, h, of the balloon as a function of the number of seconds, s that it has been raising.

Since the balloon rises at a constant rate, we find this rate by using the initial and final values of height and time at 5 seconds and 20 seconds respectively which are 12 feet and 52 feet respectively.

So, rate = gradient of line

= change in height/change  in time

= (52 ft - 16 ft)/(20 s - 5 s)

= 36 ft/15 s

= 2.4 ft/s

Now the equation of the line which shows the height is gotten from

(h - h')/(t - t') = rate

Using h'= 16 feet and t' = 5 s, we have

(h - 16)/(t - 5) = 2.4

h - 16 = 2.4(t - 5)

h - 16 = 2.4t - 12

h = 2.4t - 12 + 16

h = 2.4t + 4

where h is the height of the balloon above the ground and t is the time spent in the air in seconds.

2. What was the height of the balloon initially before the child let it go?

We obtain the initial height of the balloon before the child let go at time, t = 0 the time before the child let go.

So, substituting t = 0 into the equation for h, we have

h = 2.4t + 4

h = 2.4(0) + 4

h = 0 + 4

h = 4 feet

So, the height of the balloon before the child let go is 4 feet above the ground.

3. Use your model to predict the height of the balloon after 90 seconds.

We insert t = 90 s into the equation for h. So,

h = 2.4t + 4

h = 2.4(90) + 4

h = 216 + 4

h = 220 feet

So, the height of the balloon after 90 s is 220 feet above the ground.

9+0.025

9.025

Answer:

H

Step-by-step explanation:

The answer is H because when is says JKLM is similar to PQRS it is say that the sides JK is equal to PQ, that the side KL is equal to the side QR, that the side LM is equal to RS and the side MJ is equal to SP.  When trying to use proportions to find out if a figure is similar to another figure you have to divide a side that is congruent to another side length. For example side QR is congruent to side KL and side PS is congruent to the side JM so if you were to QR/KL it would be equal to PS/JM because the figures are similar if that makes sense. ( sorry if this doesn't make sense it's hard to explain this concept virtually.)

Answer:

12.5

Step-by-step explanation:

y= kx

k= y/x

x= 5, y= 12

k = 12/5

Therefore the value of x when y is 30 can be calculated as follows

y = kx

30= 12/5x

x= 30÷12/5

x= 30× 5/12

x= 150/12

x= 12.5

Answer:

x = 7

x = -7

Explanation:

x² = 49

[tex]\bold{x=\sqrt{49},\:x=-\sqrt{49}}[/tex]

√49 = 7

-√49 = -7

x = 7, x = -7

Answer:

she reads 4 pages per minute hope this helps

Step-by-step explanation:

Answer:

4.1 pages per minute

Step-by-step explanation:

In fraction form we want one minute not five minutes

20.5/5 is what we have but we need x/1

To do this we divide by 5 for the denominator and numerator

20.5/5=4.1

5/5=1

Our answer is 4.1/1 or just 4.1

In ratio form it would be:

pages:minutes

20.5:5

4.1:1

Answer:

Circumcenter

Step-by-step explanation:

The three perpendicular bisectors of the sides of a triangle meet in a single point, called the circumcenter . A point where three or more lines intersect is called a point of concurrency. So, the circumcenter is the point of concurrency of perpendicular bisectors of a triangle.

Answer:

Its A. g = 11

Step-by-step explanation:

Follow PEMDAS (Parantheses, exponents, multiplication, division, addition, and subtraction)

(g = 11 - 9 = 2)

7(2) = 14

14 + 12 = 26

I hope this helps u! :D

Answer:

  (A)  g = 11

Step-by-step explanation:

We can find out by undoing what is done to g.

  26 = 7(g -9) +12

  14 = 7(g -9) . . . . . . . . subtract 12

  2 = g -9 . . . . . . . . . divide by 7

  11 = g . . . . . . . . . . add 9

The value of g that makes the equation true is g = 11.

Answer:

t(d) = 246d + 1200

Step-by-step explanation:

t(d) = p(d) + b(d)

Where,

t(d) = Bernice's total monthly income

p(d) = monthly paycheck

b(d) = babysitting earnings

d = number of weekdays

p(d) = 210d + 1100

b(d) = 36d + 100

t(d) = p(d) + b(d)

= (210d + 1100) + (36d + 100)

= 210d + 1100 + 36d + 100

= 246d + 1200

t(d) = 246d + 1200

Answer: (-∞,2)

Step-by-step explanation: 2 is not included in the interval since at x=2, the function crosses the x axis, meaning it is not positive, and instead 0.

All x values below 2 are positive.
