Find the slope of the line
8 – 7x = 4y

Answers

Answer 1

Step-by-step explanation:

y = mx + c

8 - 7x = 4y

4y = 8 - 7x

y = (8 - 7x)/4

= 2 - 7/4x

y = -7/4x + 2

Slope = m = -7/4

Answer 2

Answer:

slope = - [tex]\frac{7}{4}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

8 - 7x = 4y, that is

4y = - 7x + 8 ( divide all terms by 4 )

y = - [tex]\frac{7}{4}[/tex] x + 2 ← in slope- intercept form

with slope m = - [tex]\frac{7}{4}[/tex]

a sphere has a volume of 4500 cubic inches. What is the radius off the shpere

Answers

Answer:

The radius of sphere with volume 4500 cubic inches is 10.24 inches.

Step-by-step explanation:

Let V be the volume of the sphere

Given

Volume of sphere = V = 4500 cubic inches

Let r be the radius of the sphere

The volume of the sphere is given by the formula

[tex]V = \frac{4}{3}\pi r^3[/tex]

Putting the known values

[tex]4500 = \frac{4}{3} * \frac{22}{7} * r^3\\4500 = \frac{88}{21} * r^3\\r^3 = \frac{21}{88} * 4500\\r^3 = 1073.8636[/tex]

Taking cube root on both sides

[tex]\sqrt[3]{r^3} = \sqrt[3]{1073.8636} \\r = 10.2403[/tex]

Rounding off to nearest hundredth

The radius is: 10.24 inches.

Hence,

The radius of sphere with volume 4500 cubic inches is 10.24 inches.

It would be E, 11 because when you subtract the other by 8 the answer would be less than or equal to 2

Answer:

E. 11

Step-by-step explanation:

Replace the m with 11.

11-8[tex]\leq[/tex] 2  this would simplify to

3 [tex]\leq[/tex]2 which is false.

However if you took m and replaced it with 10

10-8[tex]\leq[/tex]2 and simplified

2[tex]\leq[/tex]2 which is true. Therefore any number 10 or lower would make this true.

That means 10% of 40 is 4.

Know that means you have to times 4 by 8

4x8=32

Now you know what 80% of 40 is.

Now we need to know what the 5% is. So if 4 is 10% . 5% must be 2.

Next we have to add 2 to 32.

32 + 2 = 34

$15 dollars left after you purchased everything except the purse.

Step-by-step explanation:

A bacteria colony started with 2 bacteria. The colony is growing exponentially at 10% per hour. How long will it take to have 1 million bacteria?

Answers

Answer:

the time taken for having 1 million bacteria is 137.68 hours  

Step-by-step explanation:

The computation is shown below:

y = 2 × (1.10)^x

1,000,000 = 2 × (1.10)^x

500,000 = (1.10)^x

x = log (500,000) ÷ log (1.10)

= 137.68 hours

hence the time taken for having 1 million bacteria is 137.68 hours
