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:

Function - Yes

Domain - [-3,0,3,4]

Range - [1,2,2,5]

Step-by-step explanation:

In a function, x-values cannot repeat and in this relation, x's do not repeat, therefore it is a function. The domain is the x-values on the graph from least to greatest; so to find the domain, simply take the first value of each coordinate and order them from least to greatest. Then, the range is the y-values, so to find the range take the second value from each coordinate and order them from least to greatest.

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: (-∞,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.

if the bottom numbers are the same you can subtract the top numbers like normal

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

Step-by-step explanation:

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.

Step-by-step explanation:

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

Equality Properties

Step-by-step explanation:

Step 1: Define

2x - 12 = -52

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that -52 does indeed equal -52.

∴ x = -20 is the solution to the equation.

Answer:

[tex]2x - 12 = - 52 \\ 2x = - 52 + 12 \\ 2x = - 40 \\ \boxed{x = - 20}[/tex]

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:

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
