Answer: A, The line starts at 9 and ends at 29

Answer:

y = [tex]\frac{1}{3}[/tex]x + 3

Step-by-step explanation:

y = mx + b

y = mx + 3 (the y-intercept was given (0,3))

[tex]\frac{3 - 0}{0 + 9}[/tex] = [tex]\frac{3}{9}[/tex] = [tex]\frac{1}{3}[/tex]

y = [tex]\frac{1}{3}[/tex]x + 3

Answer:

The temperature outside a plane flying at an altitude of 5 kilometers is -15° C

Step-by-step explanation:

300000 will be your monthly payment.

Answer:

I believe monthly payment would be $645.17

Step-by-step explanation:

Interest = Principal x rate x time

Interest = 158000(.049)(30)

Interest = $232,260

Principal + Interest = 390,260

390,260 divided by 360 months (30 yrs at 12 months per yr) = 645.17

Answer: the point is 96 inches

Step-by-step explanation:

32 x 3 = 96

Answer:

I'm pretty sure it's 48

Step-by-step explanation:

Since the signs length is 3 times it's width and the perimeter is just adding up all sides I found the width to be 4 and the length to be 12. Which adds up to 32. If you multiply length times width to get the area it's 48.

Step-by-step explanation:

Answer:

x < - 7

Step-by-step explanation:

Step 1:

x + 9 < 2            Inequality

Step 2:

x < 2 - 9        Subtract 9 on both sides

Step 3:

x < - 7        Combine Like Terms

Answer:

x < - 7

Hope This Helps :)

Answer:

Step-by-step explanation:

here are the steps

step 1

x+9<2  equation.

step 2

x+9(-9)<2(-9)  add -9 to both sides

step 3

x+0<-7

x<-7

so you get your answer

Question:

If g(x) is the inverse of f(x) and f(x) = 4x+12 what is g(x)?

Answer:

[tex]g(x) = \frac{x}{4} -3[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 4x + 12[/tex]

Required

Find g(x)

[tex]f(x) = 4x + 12[/tex]

Replace f(x) with y

[tex]y = 4x + 12[/tex]

Swap the positions of y and x

[tex]x = 4y + 12[/tex]

Make y the subject: Subtract 12 from both sides

[tex]x -12= 4y + 12-12[/tex]

[tex]x -12= 4y[/tex]

Make y the subject: Divide through by 3

[tex]\frac{x}{4} -\frac{12}{4}= \frac{4y }{4}[/tex]

[tex]\frac{x}{4} -\frac{12}{4}= y[/tex]

[tex]y = \frac{x}{4} -\frac{12}{4}[/tex]

Since g(x) is the inverse, replace y with g(x)

[tex]g(x) = \frac{x}{4} -\frac{12}{4}[/tex]

[tex]g(x) = \frac{x}{4} -3[/tex]

Answer: 547 [tex]\frac{1}{8}[/tex]

Step-by-step explanation:

Answer:

[tex]Expected\ Value = 9[/tex]

Step-by-step explanation:

Given

Cereal A

[tex]Probability = \frac{1}{4}[/tex]

[tex]Grams = 4[/tex]

Cereal B

[tex]Probability = \frac{5}{8}[/tex]

[tex]Grams = 10[/tex]

Cereal C

[tex]Probability = \frac{1}{8}[/tex]

[tex]Grams = 14[/tex]

Required

Determine the expected value of grams of sugar

This is calculated by multiplying the probability and grams of sugar in each cereal.

The results of the products are then added together

i.e.

[tex]Expected\ Value = \frac{1}{4} * 4 + \frac{5}{8} * 10 + \frac{1}{8} * 14[/tex]

[tex]Expected\ Value = 1 + \frac{50}{8}+ \frac{14}{8}[/tex]

[tex]Expected\ Value = 1 + 6.25 + 1.75[/tex]

[tex]Expected\ Value = 9[/tex]

Hence;

The expected value of grams of sugar is 9 grams

Answer:

you should get 6 four-packs

Step-by-step explanation:

5.28/6= .88 dollars per roll

3.40/4=.85 dollars per roll

buying six four packs is a better price

Answer:

c. [tex]y = \sqrt{x - 1} + 4\\[/tex]

Step-by-step explanation:

The x-1 is there because you can see that the starting point is 1 left from the y axis, and +4 because it starts four points above the x axis.

Answer:

Step-by-step explanation:

As per given the formula for distance is:

If s = 9 m/s, then the distance is:

Answer:

Please check the explanation.

Step-by-step explanation:

Given that

NOW LET US SOLVE THE BLANKS

Point (2, 4) means the x-value is: x=2, and y-value is: y=4

so

y = __4__     ,      m = __-1__      ,    and     x = __2__

y=mx+b

_4_ = -1 (__2__)+b

_4_ = _-2_ + b

_6_ = b

The y-intercept is _6_.

The equation of line is y = _-1_ x + _6_
