3 4. What is the slope of the line that passes through (-2, 1) and (8,5)? ​

Answers

Answer 1

Answer: 2/5

Explanation: Ask if you want an explanation!

Answer 2
Answer:    slope = ²/₅

Step-by-step explanation:      

      The question gives us two points, (-2, 1) and (8,5), from which we can find the slope and later the equation of the line.

Finding the Slope

The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)      

                                          =  (5 - 1) ÷ (8 - (-2))    

                                          =   ⁴/₁₀

                                          = ²/₅  

Checking my answer:

We can check to see if the answer is correct by drawing the line and seeing if it passes through both points. If it does, then the slope is correct.

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:

                                ⇒  y - 1 =  ²/₅ (x + 2)

                                       

In the graph below (created using Desmos), the line passes through both points. This suggests that we calculated the slope correctly.

3 plus four times a number.

Answers

Answer:

3 + 4x

Step-by-step explanation:

Let "a number" be x.

Therefore "four times a number" is 4 multiplied by x which is 4x.

Now add 3 for "3 plus".

3 + 4x

Answer:

Our equation would be: 3 + 4x.

Let's say x=8

That would now make our equation:

3 + 4(8) =

Step-by-step explanation:

But let's solve this equation :)

First, we would add 3+4, to get 7.

Then, we would multiply the 7 by 8.

Lastly, we know 7 x 8 = 56

So, 3+4(8)= 56

But we could also create a function statement out of this.

Our statement for this equation would be:

When x equals 8 the answer or in algebraic terms the "output" is 56.

Have a great day!!

A large koi pond is filled from a garden hose at the rate of 12 gal/min. Initially, the pond contains 200 gal of water.
(a) Find a linear function V that models the volume of water in the pond at any time t.
(b) If the pond has a capacity of 1304 gal, how long does it take to completely fill the pond?

Answers

a) The linear function that models the amount of water after t minutes is given by:

[tex]V(t) = 200 + 12t[/tex]

b) It takes 92 minutes to completely fill the pond.

Item a:

Initially, the pond contains 200 gal of water, that is, the linear function has a y-intercept of 200.Filled at a rate of 12 gallons per minute, thus the linear function has a slope of 12.

Then, the function is:

[tex]V(t) = 200 + 12t[/tex]

Item b:

It takes t minutes to fill the pond, t is found for which:

[tex]V(t) = 1304[/tex]

Then

[tex]200 + 12t = 1304[/tex]

[tex]12t = 1104[/tex]

[tex]t = \frac{1104}{12}[/tex]

[tex]t = 92[/tex]

It takes 92 minutes to completely fill the pond.

5. Gardener Gary planted 21 rows of tomatoes
and squash. He planted twice as many rows of
tomatoes as rows of squash. How many tomato
plants were planted if there are 12 plants per
row?

Answers

Answer:

168

Step-by-step explanation:

first find out how many rows of squash there are

21 = x + 2x

21 = 3x

7 = x

then find out how many rows of tomatoes there are

7 × 2 = 14

if there are 12 plants per row, we can multiply

14 × 12 = 168

Gardener Gary planted 168 tomato plants

How to determine the number of yellow leaves?

Let the rows of tomato be x and the rows of squash be y.

So, we have:

x + y = 21

The statement twice as many rows of tomatoes as rows of squash means that:

x = 2y

Substitute x = 2y in x + y = 21

2y + y = 21

This gives

3y = 21

Divide by 3

y = 7

Substitute y = 7 in x = 2y

x = 2 * 7

x = 14

This means that Gary planted 14 rows of tomato.

The number of tomato plants is then calculated using

Tomato plants= 14 * plants per row

This gives

Tomato plants = 14 * 12

Evaluate the product

Tomato plants = 168

Hence, Gardener Gary planted 168 tomato plants

Answer:

-32

Step-by-step explanation:

if we multiply - 2 and -6 it becomes positive so it will be 12.

-2 multiply 22 will be -44

12 - 44 is -32.

answer : -32

you distribute so you do -2 times -6 which is 12. then -2 times 22 which is -44.

you end up with 12 - 44, which equals -32.

if f(x)=3x-1 and g(x)=x+2,find (f+g)(x)

Answers

Answer:

(f + g)(x) = 4x + 1

Step-by-step explanation:

Given f(x) = 3x - 1 and g(x) = x + 2, find (f + g)(x):

We can rewrite (f + g)(x) as f(x) + g(x), and solve the composite functions through addition:

f(x) + g(x) = (3x - 1) + (x + 2)

Combine like terms:

f(x) + g(x) = 3x + x + 2 - 1 = 4x + 1

Therefore, (f + g)(x) = 4x + 1.
