Answer:

D. 12 feet

Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

Where L is length and W is the width.

Given

perimeter = 82 feet

Length is 5 more than 2w

That’s L = 5 + 2w

Now substitute 5 + 2w for L in the formula above

We have

82 = 2 ( 5 + 2w + w)

Simplify the bracket

82 = 2(5 + 3w)

Distribute 2 into (5 + 3w)

82 = 2 x 5 + 2 x 3w

82 = 10 + 6w

Subtract 10 from both sides

82 - 10 = 10 - 10 + 6w

72 = 6w

Divide both sides by 6

72/6 = 6w/6

12 = w

W = 12 feet

There must be 23 students in Ms.Gardner's class because 23 - 30%=6.9 so 7 students are in her class are in the play because if you look at Mr.Logan's class he has 23 students to and there are aslo 7 students in his class are in the play so Mr. Logan's class is basically is holding Ms.Gardner's place

Which of the following represents the domain and range of y = sin x?
shtirl [24]

Answer:

3rd choice

Step-by-step explanation:

The domain is (-infinity, infinity) because you can keep subtracting multiples of 360 until you get a value under 360. For the range, imagine a unit circle.

The y coordinate is the sin value, so it is just [-1, 1].

So the answer is the 3rd choice.

What is the​ slope-intercept form of the equation of the​ line? (-6,6) , (9,1) PLZZZZ help me on this
Igoryamba

Heya! Alexis

Line is Passing through the Points (-6 , 6) and (9 , 1)

Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :

\heartsuit\;Slope(m) = \frac{y_1 - y_2}{x_1 - x_2}

here x₁ = -6 and x₂ = 9 and y₁ = 6 and y₂ = 1

\heartsuit\;Slope(m) = \frac{6 - 1}{-6 - 9} = \frac{5}{-15} = \frac{-1}{3}

We know that the form of line passing through point (x₀ , y₀) and having slope m is : y - y₀ = m(x - x₀)

Here the line passes through the point (-6 , 6) and (9 , 1)

We can take any one point of the both

let us take (-6 , 6)

x₀ = -6 and y₀ = 6 and we found m = \frac{-1}{3}

Equation of the line :

⇒ y - 6 = \frac{-1}{3}(x + 6)

⇒ 3y - 18 = -x - 6

⇒ 3y = -x + 12

⇒ Slope - Intercept Form :  y = (\frac{-1}{3})x + 4
