Answer:

D. y = 1/2x + 3

Step-by-step explanation:

y = mx + b

m = slope

b = the y-intercept

To find the slope we can do rise over run or y/x

r/r = 1/2

The slope is 1/2

To find the y-intercept, is where the line hits the y axis which is at.....

3

So...

y = 1/2x + 3

Hope this helped!

Answer:

D

Step-by-step explanation:

the answer is D because the line starts and three and rises 1 and over 2. its not negative because the line goes up

Answer:

4 bags

Step-by-step explanation:

50 people = 4 cups

300 people = 24 cups

24 cups ÷ 6 cups a bag = 4 bags

The bags of sugar that will be needed to make this recipe for 300 people will be 4 bags.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

A pudding recipe for 50 people calls for 4 cups of sugar. The ratio of the number of cups of sugar to the number of people. Then we have

Rate = 4 / 50

Rate = 2 / 25 cups per person

If the number of people is 300. Then the number of cups of sugar will be given as,

⇒ (2/25) x 300

⇒ 24 cups

The number of bags of sugar is given as,

⇒ 24 / 6

⇒ 4 bag

The sacks of sugar that will be expected to make this recipe for 300 individuals will be 4 packs.

Hey there!

The answers to your question are C, D, and E

If there are repeats in the X column, then it's not a function. If there are no repeats, then it is! If there are repeats in the Y column, that's ok, but there cannot be repeats in the X column.

Hope this helps! If you need any other help, just tell me!

Answer:

(2x +30) and (3x -5)  (they're opposite to eachother, so they're equal)

2x + 30 = 3x - 5 (set them equal to eachother, then subtract 3x from both side)

-1x = -35 (divide both sides by -1 to isolate x)

x = 35 or B (this is your answer)

Answer:

762%

Step-by-step explanation:

Volume of a cube = s³

Volume of the cube is then

V = 5.08 * 5.09 * 5.1

V = 131.87 cm³

Percentage errors are calculated by the formula

%E = (V.a - V.e)/V.e * 100%, where

%E = percentage error

V.a = actual volume

V.e = expected volume

%E = (131.87 - 15.3) / 15.3 * 100%

%E = 116.57 / 15.3 * 100%

%E = 7.62 * 100%

%E = 762%

Therefore, the percentage error is a whooping 762% which is a whole lot!

Answer:

The volume is increasing at a rate of 16286 in³/min.

Step-by-step explanation:

a) The volume of a cone is given by:

[tex] V = \frac{1}{3}h\pi r^{2} [/tex]

Where:    

r: is the radius

h: is the height

The rate of change of the volume can be calculated by using the chain rule:

[tex] \frac{dV}{dt} = \frac{\pi}{3}[\frac{dh}{dt}r^{2} + h\frac{d(r^{2})}{dt}] [/tex]

Since h = 4/3 r we have:

[tex] \frac{dV}{dt} = \frac{\pi}{3}[\frac{d(\frac{4r}{3})}{dt}r^{2} + \frac{4r}{3}\frac{d(r^{2})}{dt}] [/tex]

[tex] \frac{dV}{dt} = \frac{4\pi}{9}[\frac{dr}{dt}r^{2} + r\frac{d(r^{2})}{dt}] [/tex]        

[tex] \frac{dV}{dt} = \frac{4\pi}{9}[\frac{dr}{dt}r^{2} + 2r^{2}\frac{dr}{dt}] [/tex]    (1)    

With:

[tex]\frac{dr}{dt}[/tex] = 3 in/min

[tex]r = 3 ft*\frac{12 in}{1 ft} = 36 in[/tex]

And by entering the above values into equation (1) we have:

[tex] \frac{dV}{dt} = \frac{4\pi}{9}[(3 in/min)*(36 in)^{2} + 2*(36 in)^{2}*3 in/min] [/tex]

[tex]\frac{dV}{dt} = 16286 in^{3}/min[/tex]

Therefore, the volume is increasing at a rate of 16286 in³/min.

I hope it helps you!

Answer:

x=-25.5

Step-by-step explanation:

5/2(-13) +7=-25.5

Answer:

The value of x = -1/8

Step-by-step explanation:

Given

[tex]f\left(x\right)=\frac{5}{2x}+7[/tex]

[tex]f(x)=-13[/tex]

To determine

The value of x = ?

Using the function

[tex]f\left(x\right)=\frac{5}{2x}+7[/tex]

substituting f(x) = -13 in the function

[tex]-13=\frac{5}{2x}+7[/tex]

Subtract 7 from both sides

[tex]-13-7=\frac{5}{2x}+7-7[/tex]

Simplify

[tex]-20=\frac{5}{2x}[/tex]

Multiply both sides by 2x

[tex]-20\cdot \:2x=\frac{5}{2x}\cdot \:2x[/tex]

Simplify

[tex]-40x=5[/tex]

Divide both sides by -40

[tex]\frac{-40x}{-40}=\frac{5}{-40}[/tex]

[tex]x=-\frac{1}{8}[/tex]

Therefore, the value of x = -1/8
