Answer:

should be -8

Step-by-step explanation:

Answer: t = 7-15 = -8

Step-by-step explanation:

Answer:

-12.9

Step-by-step explanation:

Using slope formula

m = (y2 -- y1) / (x2 -- x1)

m= slope

Plug in values, for x1 if you use 4 you must then for x2 use -2 but if you use -2 for x1 you must use 4 for x1, simply, if you go left to right, you cant go right to left on the next one.

m = (3 --4) / (4 --2)  

m= 7 / 6

Answer:

The ladder is 5.20 feet tall on the side of the building

Step-by-step explanation:

Here, we simply want to calculate the height the ladder is from the base of the building

To get this, we need a pictorial representation of what we have here.

From what we have here, we have a right-angled triangle with a hypotenuse of 10 foot and a base of 3 feet

We apply Pythagoras’ theorem to get how far is the tip of the ladder from the base of building

Pythagoras’ stated that the square of the hypotenuse equals the sum of the squares of the two other sides

In this case, let the height be x

So;

x^2 + 3^2 = 6^2

x^2 = 6^2 - 3^2

x^2 = 36 - 9

x^2 = 27

x = √27

x = 5.196 feet

which to two decimal places is 5.20 feet

Answer:

constant of variation (k) = 6

Step-by-step explanation:

Let us first represent the sentence in direct variation expression:

"the gallons of water used to take a shower varies directly with the number of minutes in the shower"

Let the gallons of water used = g

Let the number of minutes spent in the shower = m

g ∝ m

where: ∝ = sign of proportionality

This means that as g increases, m increases also, and the same holds for decrease too.

g ∝ m

g = km

where k = constant of variation ( or proportionality constant)

Next, If a 6-minute shower uses 36 gallons of water, find the constant of variation

g = 36 gallons

m = 6 minutes

∴ g = km

= 36 = k × 6

k = 36 ÷ 6 = 6

k = 6

Answer:

P2 + 2P - 24

Step-by-step explanation:

Answer:

Length --> x

Width --> y

Perimeter of a rectangle --> 2x + 2y

The length is always 4 cm more than double the width

x - 4 = 2y

y = (x-4)/2

x = 2y + 4

a. The polynomial equation to give the perimeter --> 2(2y+4) + 2((x-4)/2)

b. x - 4 = 2·6 --> x - 4 = 12 --> x = 16

  Perimeter --> 2·16 + 2·6 = 44 cm

Answer:

y-1=2(x-2)

Step-by-step explanation:

Since the slope is 2, that number is multiplied by x. Then the y subtracts the x value point and the x subtracts the y.

An equation in point-slope form of the line that passes through the point (2,1) and has a slope of 2 is y=2x-3.

Given that, the coordinate point is (2, 1) and slope m = 2.

The point slope form is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point. The standard form of the slope intercept form is y=mx+b.

Put (x, y) = (2, 1) and m = 2 in y=mx+b and solve for b.

That is, 1=2(2)+b

⇒ b = -3

Now, substitute m = 2 and b = - 3.

So, y=2x-3

Therefore, an equation in point-slope form of the line that passes through the point (2,1) and has a slope of 2 is y=2x-3.
