Answer:

y- intercept is (0, 2)

Slope is -5/2

Answer:

L=7

W=13

Perimeter=40

Area=91

Step-by-step explanation:

Perimeter = 2L+2W

40=2(7)+2W

40=14+2W

-14  -14

26=2W

Divide both sides by 2

13=W

Area=L x W

7 x 13 = 91

Answer:

length = 7 units

width = 13 units

area = 91  square units

perimeter = 40 units

Step-by-step explanation:

What is the area of a rectangle?

  ❖ The area of a rectangle can be found by multiplying the length and

       width of the rectangle.

What is the perimeter of a rectangle?

  ❖ The perimeter of a rectangle is the sum of all sides- length and

       width. In this case, we're given the perimeter as 40 units and the

       length as 7 units, but the width is unknown. Formula to find

       perimeter of rectangle is 2(l + w) = P.

Solving for Width

Solving for Area

The slope can be found with two sets of points

The points can be any points, but in this case I choose the point (-1,10) and (1,2)

Slope = [tex]\frac{y2-y1}{x2-x1} =\frac{10-2}{-1-1} =\frac{8}{-2} =-4[/tex]

The slope of the line that contains these points is -4.

1. 2(2w + w)

2. 2(2w) + 2(w)

Step-by-step explanation:

The formula to find the perimeter of a rectangle is [tex]2(l+w)[/tex], and we can easily apply it with this rectangle as 2(2w + w).

You can find another expression by simplifying 2(2w + w), which is 2(2w) + 2(w).

Answer:

[tex]\frac{ (x+3)^2}{9} + \frac{ (y-2)^2}{4} =1[/tex]

-step explanation:

The standard form of the given equation was reduced, representing an ellipse.

The given equation is:

[tex]4x^{2} +9y^{2} +24x-36y+36=0[/tex]

An equation is a statement that equates to two expressions.

We know the above equation represents an ellipse.

Rearranging the given equation

[tex]4x^{2} +24x+9y^{2} -36y+36=0[/tex]

[tex]4(x^2+6x)+9(y^{2} -4y)+36=0[/tex]

[tex]4(x^2+6x+9)+9(y^{2} -4y+4)=36[/tex]

[tex]4(x+3)^2+9(y-2)^2=36[/tex]

[tex]\frac{4(x+3)^2}{36}+\frac{9(y-2)^2}{36} =1[/tex]

[tex]\frac{(x+3)^2}{9}+\frac{(y-2)^2}{4} =1[/tex], which is the standard form of the given equation.

Hence, the standard form of the given equation was reduced.

Answer:

y=2x+2

Step-by-step explanation:

the equation for slope intercept form is y=mx+b where b is the y intercept and m is the slope. From the graph we can see that where x is 0 y is 2 which makes 2 be the y intercept, and when x is 1 y is 4 which then you replace y for 4 and x for 1 which would be 4=m(1)+2,now u subtract 2 from both sides which leaves you with 2=m(1) and m times 1 is m so now your left with 2=m which means the slop is 2

Answer:

Which substance dissolves in water?

Step-by-step explanation:

The student adds the same amount of substance of different types i.e., 10 grams to each beaker and the same amount of water i.e., 100 mL to each beaker. All of them are stirred and observations are taken down at the end of thirty minutes.

That is all that is mentioned in the question. The student is most likely measuring which substance dissolves in water. As all the other variables are kept constant.

So, the student here is most likely trying to answer the question "Which substance dissolves in water?"

Jade's work makes sense, Peter's does not.

Step-by-step explanation:

What's wrong with Peter's work:

Peter did not apply associative property correctly. You cannot change what is inside the parenthesis. He also shouldn't be using associative property to solve this equation because it just doesn't make sense!

Jade's work:

She applied distributive property correctly and multiplied each term in the parenthesis by 2. All of her processes are logical and make sense! I could go on, but everything is correct lol

Best of wishes mate!

Answer:

Jade because she followed the correct order of operations.

Step-by-step explanation:

Always remember your order of operations.

P - parentheses

E - exponents

M - multiplication

D - division

A - addition

S - subtraction

Answer:

(3, -1) or x=3, y=-1

Step-by-step explanation:

using substitution for y, the first equation becomes 3(-2x + 5) - 2x = -9

distribution of the 3 gets your equation to be -6x + 15 - 2x = -9

from here you combine like terms to get -8x + 15 = -9

from here it's just a two step equation

subtract 15 from both side to get -8x = -24

divide and get x = 3

substitute x in the equation for y to get y = -2(3) + 5

distribution gets you y = -6 + 5, which makes y = -1

to check your work you can just plug in the variables equivalents in the first equation, which upon doing you can see that the answer is indeed 3, -1

The function of the brand new smartphone is an exponential function

The function that models the value of the phone x years after its puchase is f(x) = 1200(0.867)^x

The given parameters are:

Initial value (a) = $1200

Rate (r) = 13.3%

An exponential function that represents a decrement in value is illustrated using:

[tex]f(x) = a(1 - r)^x[/tex]

Substitute known values

[tex]f(x) = 1200(1 - 13.3\%)^x[/tex]

Evaluate the difference

[tex]f(x) = 1200(0.867)^x[/tex]

Hence, the function that models the value of the phone x years after its puchase is f(x) = 1200(0.867)^x
