Step-by-step explanation:

Since, the function f(x) is continuous at x=3.

Therefore,

· k=lim

x→ 3

· x−3

(x+3)

−36

· k=lim

x→ 3

· x−3

(x+3)

· k=lim

x→ 3

· x−3

(x+3−6)(x+3+6)

· k=lim

x→ 3

· x−3

(x−3)(x+9)

· k=lim

x→ 3

· (x+9)

What is the length of the unknown side of the right triangle?

A right triangle with hypotenuse x and legs 21 and 20

21
29
400
441

Answers

Answer:

the answer is 29

Step-by-step explanation:

a^2 + b^2 = c^2 (btw ^ means to the power)

a and b are the legs. c is the hypotenuse

21^2 + 20^2 = c^2

441 + 400 = 481

then we have to square it.

the square root of 481= 29.

btw the hypotenuse is always going to be bigger than the legs.

hope it helps!! btw it is right!

clearance items in a store are all marked down proportionally. A shirt with an original price of $32 is on clearance of $12. what is the clearance price of the shirt with an original price of $40?

Answers

Answer:

$15

Step-by-step explanation:

Set up a proportion where x is the clearance price of the $40 shirt:

[tex]\frac{32}{12}[/tex] = [tex]\frac{40}{x}[/tex]

Cross multiply and solve for x:

32x = 480

x = 15

So, the clearance price is $15

The answer is 20 bucks 8 plus 32 =40 8+12=20

Step-by-step explanation:

At what point does the line given by the following equation cross the y-axis?
y = (4/11)x - 9

A. (0, 11/4)
B. (-9, 0)
C. (0, -36/11)
D, (0, -9)

Answers

Pretty sure the answer is D:

Because the equation is in the format y=mx+c (c being the y intercept), we know that the y intercept (or where the line will cross the y axis) will be -9.

B also says -9 but we have to be careful because it states that the x axis is -9 rather than the y axis.

Hope that helped you understand.

The temperature changed by -2 degrees F per hour from noon on Tuesday until 10:00
AM the following morning. The temperature at 8 PM on Tuesday was 49F.
What was the temperature at 4:00 PM on Tuesday?
What was the temperature at 12:00 PM on Tuesday?
When was the temperature 30o F?

Answers

Answer:

At 4:00 pm it was 31 F so at 3:30 it's at 30 F and at 12:00 it would be 23 F

Step-by-step explanation:

8 - 4 = 4pm

2 * 4 = 8 degrees

49 - 8 = 31 F

2 - 1 = 1 which is a half so 60 min divided by 1/2 is 30 so take 4:00 - 30min is 3:30

4pm to 12pm in time is 4

2 * 4 = 8

31 - 8 = 23 F

Answer:

At 4:00 pm it 31 F  at 3:30 it at 30 F and at 12:00 it will be 23 F

the equation of the line that passes through the points (0,−4) and (2,−2)

Answers

Answer:

y = x - 4

Step-by-step explanation:

Answer:

y = x - 4

Step-by-step explanation:

Use slope intercept form: [tex]\frac{y2-y1}{x2-x1}[/tex]

-2 is y2, -4 is y1, 2 is x2, and 0 is x1. Plug in these values

[tex]\frac{-2-(-4)}{2-0}[/tex]

[tex]\frac{-2+4}{2}[/tex]

[tex]\frac{2}{2}[/tex]

[tex]1[/tex]

1 is the slope. Grab a y coordinate in one of the coordinate pairs. I will choose -2. Choose a x value too. I will choose 2. Plug in the values in the equation y = mx + b.

-2 = 2 + b

Figure out b.

b = -4

Since we know the value of b and the slope, plug in the values to y = mx + b.

y = 1x - 4 or y = x - 4

y = x - 4 is the equation. Let me know if I got anything wrong. I hope this helps!
