Answer 1

Answer:

3. W=4, L=10

4. W=4, L=8

Step-by-step explanation:

3.

L = 3W-2

W = W

P = 2L + 2W

P = 2(3W-2)+2W

P=28

2(3W-2)+2W=28

8W-4=28

8W=32

W=4

L=3W-2, or 10

Check: 2(4)+2(10) = 28? Yes

4.

L=2W

W=W

P=24

2L+2W=24

2(2W)+2W=24

6W=24

W=4

L=8

Check: 2(8)+2(4)=24 ? 16+8 = 24 Yes

(3,7) is not a solution

Step-by-step explanation:

You fill in the values x=3 and y=7 in both equations and see if you end up with something that is true.

-5·3 - 2·7 = 23 is not true, because it simplifies to -29 = 23

no need to look further, but if you would, the second equation is also false:

3 + 4·7 = -19 is also not true.

The real solution by the way is (-3, -4).

The area of a fenced in back yard can be 144 square feet. The owners are trying to decide on the dimensions of the back yard, and have decided they want the length to be 10 feet more than its width. What will the dimensions of the back yard be?

Answers

A rectangle can be defined as a 4 sided geometric figure.  One side of a rectangle is longer than the other sides. A rectangle can also be referred to as a quadrilateral.

The dimensions of the background are given as Width: 8 feet and the  Length: 18 feet

The formula for the area of a rectangle is Length x Width.

The question says:

The owners want the length to be 10 feet more than its width. Hence:

L = W + 10

The area of the fenced backyard = 144 square feet.

Hence,

(W + 10) x W = 144

W² + 10W = 144

Rewriting the equation

W² + 10W - 144 = 0

We factorize the algebraic expression above

W² - 8W + 18W - 144 = 0

W(W - 8) + 18(W - 8) = 0

(W - 8) (W + 18) = 0

W - 8 = 0, W = 8

W + 18 = 0, W = -18

Since the width cannot be a negative value, the width of the backyard is 8 feet

Solving for the Length,

L = W + 10

L = 8 + 10

L = 18 feet

The length of the backyard is 18 feet.

Therefore, the dimensions of the backyard are Width: 8 feet and Length: 18 feet.

Answers

Answer:

E    see below

Step-by-step explanation:

When dividing two fractions, you flip the second fraction over then multiply.

So the equation would then be:

3xy (2 + y)           ab

---------------  X   --------------

     2ab                3xy

The 3xy on top and bottom cancel each other out.  The ab on top and bottom cancel each other out.

So you are left with:

2 + y

-------

   2

Answer: Number E is correct.

Step-by-step explanation:

division becomes multiplication and turns upside down. ab cuts ab and 2 remains as denominator. 3xy cuts 3xy and 2+y remains as numerator. Therefore the answer obtained is 2+y/2.

What is the slope of the line whose equation is -48 = 2x - 8y?
Enter your answer in the box.

Answers

Answer:

The slope is [tex]\frac{2}{8}[/tex]

Step-by-step explanation:

Take the general equation of a straight line [tex]y = mx+c[/tex]

Here [tex]m[/tex] is the slope of the line.

So let's get the equation of the line in the question in the same form.

[tex]-48 = 2x-8y[/tex]

Add [tex]8y[/tex] to both sides: [tex]8y - 48 = 2x[/tex]

Add [tex]48[/tex] to both sides: [tex]8y = 2x + 48[/tex]

Divide by [tex]8[/tex] to get it into the general equation: [tex]y = \frac{2}{8} x + 6[/tex]

Now compare it to the general equation to find the value of [tex]m[/tex]. The value of [tex]m[/tex] is the coefficient of [tex]x[/tex] which we can see is [tex]\frac{2}{8}[/tex]

Fiona planted tomato plants in her back yard earlier this year. So far, they have produced 55 tomatoes. From past experience, she expects the tomato plants to produce an additional 14 tomatoes each week for the rest of the summer. Which of the following recursive formulas can be used to determine the total number of tomatoes produced by her plants after any given number of weeks in the summer, assuming that her expectations are correct?

Answers

Answer:

Although it is a short-lived perennial, tomato plants can bear fruit for more than one year in parts of the world that never dip below 65 degrees Fahrenheit. If you have a greenhouse and can keep it heated during the cold months, consider placing an experimental beefsteak, plum or grape tomato plant among your tropical flowers.

consider the linear function f(x)=4x-5 Find the values of x for which f(x)=3,f(x)=5,f(x)=-3

Answers

Answer:

f(2) = 3

f(5/2) = 5

f(½) = -3

Step-by-step explanation:

Given the linear function f(x) = 4x - 5:

f(x) = 3

3 = 4x - 5

3 + 5 = 4x - 5 + 5

8 = 4x

8/4 = 4x/4

2 = x

Therefore, when f(x) = 3, x = 2.

f(x) = 5

5 = 4x - 5

5 + 5 = 4x - 5 + 5

10 = 4x

10/4 = 4x/4

5/2 = x

Therefore, when f(x) = 5, x = 5/2.

f(x) = -3

-3 = 4x - 5

-3 + 5 = 4x - 5 + 5

2 = 4x

2/4 = 4x/4

½ = x

Therefore, when f(x) = -3, x = ½.
