please help me to solve this problem

Answers

Answer 1

Answer:

y = 3x -5

Explanation:

Since it's parallel, it will have the same slope: 3.

So you'll have y = 3x + a, and we need to find a.

Plug in the values for the point we are given:

7 = 3(4) + a

7 = 12 + a

a = -5

So there you have it: y = 3x - 5

Answer 2

Answer:

y=3x-5

Step-by-step explanation:

y=3x+6

since the line is parallel, the slope will be the same (but y int is still unsolved)

so plug in x,y from (4,7) in y=mx+b or y-y1=m(x-x1)

i used y=mx+b

7=3(4)+b

7=12+b

b=(-5)

so the final answer is y=3x-5

A cone has volume 12pie cubic inches. Its height is 4 inches. What is its radius?
A.) 6 inches
B.) 4 inches
C.) 12 inches
D.) 3 inches

Answers

Answer:

r = 3

Step-by-step explanation:

The formula of a volume of a cone

V= 1/3 pie r^2 H

r - radius

H - height

We have V = 12π in³ and H = 4 in. Substitute:

The radius of the cone is 3 inches

Volume of a conev = 1 / 3 πr²h

where

h = height

r = radius

Therefore,

v = 12π

h = 4

12π = 1 / 3 × π × r² × 4

12 = 4 /3 r²

36 = 4r²

r² = 36 / 4

r = √9

r = 3 inches

What Percent of 25 is 10 ?

Answers

Answer:

Step-by-step explanation:

Answer:

40% (see below)

Step-by-step explanation:

First, make a ratio to simplify your situation:

Think about it like this:

If 25 is 100%, and the question is asking me for 10, which is x%, then what is x%?

Here's what I'm talking about:

10 x%

------ = --------

25 100%

Now, just cross multiply and simplify:

1000 = 25x

40 = x

x = 40

To check your answer, you can multiply 25 by 0.4 (the decimal form of 40%) to see if it worked because 40% of 25 is 10:

25 (0.4)

The equation of the line is:

y = 3x

Step-by-step explanation:

Given the table

x y

0 0

1 3

2 6

3 9

4 12

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

m is the slopeb is the y-intercept

Taking the two points from the table

(1, 3)(2, 6)

Determining the slope between (1, 3) and (2, 6)

(x₁, y₁) = (1, 3)

(x₂, y₂) = (2, 6)

Using the formula

Slope = m = [y₂ - y₁] / [x₂ - x₁]

= [6 - 3] / [2 - 1]

= 3 / 1

= 3

Thus, the slope of the line = m = 3

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the table, it is clear

at x = 0, y = 0

Thus, the y-intercept b = 0

now substituting m = 3 and b = 0 in the slope-intercept form of the line equation

y = mx + b

y = 3x + 0

y = 3x

Therefore, the equation of the line is:

y = 3x

The graph of the line equation y = 3x is also attached.

how do you find valume in a square.

Answers

Answer:

Since each side of a square is the same, it can simply be the length of one side cubed. If a square has one side of 4 inches, the volume would be 4 inches times 4 inches times 4 inches, or 64 cubic inches.

Step-by-step explanation:

Since each side of a square is the same, you can just multiply each side. For example if a square had one side of 4 inches, just multiply 4 inches 4 times

The squirrel runs 11 miles per hour.

Explanation:

Speed can be found from the the slope of the graph of distance over time. From this graph the easiest point to calculate this on is the two endpoints. Slope is rise/run. In this graph Y has increases by 11 miles (rise) at the point where time has increased by one hour (run). So the speed can be found with 11 miles/ 1 hour which equals 11 miles per hour.
