The length of a rectangle is 3 cm longer than its width. if the perimeter of the rectangle is 46 cm , find its area.

Answer:

Step-by-step explanation:

To find the first table y = 4x + 2, to find each y value we have to substitute each x value into the equation.

4(-2) + 2 = -6 so -2 is going to have the y as -6

4(-1) + 2 = -2 so -1 is going to have the y as -2

4(0) + 2 = 2 so 0 is going to have the y as 2

4(1) + 2 = 6 so 1 is going to have the y as 6

4(2) + 2 = 10 so 2 is going to have the y as 10

So these are the points you would graph (-2, -6), (-1, -2), (0, 2), (1,6), and (2, 10)

For the next talbe y = 3x + 1 we do the same thing

3(-2) + 1 = -5 so -2 is going to have the y as -5

3(-1) + 1 = -2 so -1 is going to have the y as -2

3(0) + 1 = 1 so 0 is going to have the y as 1

3(1) + 1 = 4 so 1 is going to have the y as 4

3(2) + 1 = 7 so 2 is going to have the y as 7

The ooints to graph are (-2, -5), (-1, -2),(0,1), (1, 4) and (2,7)

For the next table y = 6x - 5

6(-2) - 5 = -17 so -2 is going to have the y as -17

6(-1) - 5 = -11 so -1 is going to have the y as -11

6(0) - 5 = -5 so 0 is going to have the y as -5

6(1) - 5 = 1 so 1 is going to have the y as 1

6(2) - 5 = 7 so 2 is going to have the y as 7

The points to graph (-2, -17), (-1, -11), (0, -5), (1, 1) and (2, 7)

For the next table y = 5 + 2x

5 + 2(-4) = -3 so -4 is going to have the y as -3

5 + 2(-2) = 1 so -2 is going to have the y as 1

5 + 2(0) = 5 so 0 is going to have the y as 5

5 + 2(3) = 11 so 3 is going to have the y as 11

5 + 2(5) = 15 so 5 is going to have the y as 15

(-4, -3), (-2, 1), (0, 5), (3, 11) and (5, 15)

For the next table y = 8x - 10

8(-4) - 10 = -42 so -4 is going to have the y as -42

8(-2) - 10 = -26 so -2 is going to have the y as -26

8(0) - 10 = -10 so 0 is going to have the y as -10

8(2) - 10 = 6 so 2 is going to have the y as 6

8(4) - 10 = 22 so 4 is going to have the y as 22

(-4, -42), (-2, -26), (0, -10), (2, 6) and (4, 22)

For the last table

2(-2) = -4 so -2 is going to have the y as -4

2(-1) = -2 so -1 is going to have the y as -2

2(0) = 0 so 0 is going to have the y as 0

2(-1) = -2 so -1 is going to have the y as -2

2(-2) = -4 so -2 is going to have the y as -4

(-2, -4), (-1, -2), (0, 0), (-1, -2) and (-2, -4)

Answer:

-3

Step-by-step explanation:

-3(x + 5) = 6 - 3(2x + 4)

-3x - 15 = 3(2x + 4)

-3x - 15 = 6x + 12

+3x          +3x

-15 = 9x + 12

-12            -12

-27 = 9x

Answer:

The watermelon candies taste $0.13 more.

Step-by-step explanation:

First, in order to find out how much each candy costs per ounce, you have to take the cost and divide it by the number of ounces. 3.48 divided by 12 is 0.29, so the watermelon candies cost $0.29 per ounce. 1.38 divided by 8 is 0.16, so the chewy chocolates cost $0.16 per ounce. In order to find how much more the watermelon candies cost, we have to subtract the cost of the watermelon candies by the cost of the chocolate candies. 0.29-0.16=0.13, so the watermelon candies cost $0.13 more than the chocolate candies.

Answer:

[tex]\frac{5}{4}[/tex]

Step-by-step explanation:

Given expression:

           [tex]\frac{3}{5}[/tex](y - 5)   =  - (y + 3) + 2

    To solve this problem, multiply both sides by 5;

  5 x   [tex]\frac{3}{5}[/tex](y - 5)   = 5[-(y + 3) + 2}

         3(y - 5) = 5(-y - 3 + 2)

         expand,

          3y - 15  = 5(-y -1)

          3y -15  = -5y - 5

    Collect like terms;

          3y + 5y  = -5 + 15

             8y  = 10

               y  = [tex]\frac{10}{8}[/tex]  = [tex]\frac{5}{4}[/tex]

Heidi uses 5 grams of tea leaves to make 25 fluid ounces of tea.

Last week she made 75 fluid ounces of tea.

To Find :

How many grams of tea leaves did Heidi use to make tea last week.

Solution :

Let, x gram of leaves are required last week.

So,

[tex]\dfrac{x}{5}=\dfrac{75}{25}\\\\x = 5\times\dfrac{75}{25}\\\\x = 5\times 3\\\\x = 15 \ grams[/tex]

Therefore, 15 grams of tea leaves is used last week.

Hence, this is the required solution.

principal p= $2000

Rate r= 1.75% = 0.0175

time t= 18-16= 2years

Required

The final amount of the compounded principal

The compound interest formula is

A=P(1+r)^t

A=2000(1+0.0175)^2

A=2000(1.0175)^2

A=2000*1.0353

A=2070.6

The account when she turns 18 will be $2070.6

Step-by-step explanation:

(a)= 6×2= 12

(c)= 0.7×2=1.4

the following characteristic of the polygon that are the same are A SIDE LENGTH AND B AREA

Translation is a rigid transformation.

The characteristics that will remain the same are: (a) side length and (b) area

When a polygon is translated, the polygon undergoes a rigid transformation.

A rigid transformation does not change the side length and angle of a shape.

However, the coordinates would change; because the polygon would change its position after translation.

Hence, the correct options are:

(a) and (b)

Hope this helps and if you could mark me as brainliest. Thanks!

Answer:

To determine the y-intercept, convert the equation into slope-intercept form.

x + 2y = -4

Subtract x from both sides

2y = -x-4

divide by 2 on both sides

y = -1/2(x) - 2 (this is the formula, with a slope of -1/2 and y-intercept of -2

This gives you a y-intercept of -2, which can be plotted at (0, -2)

For the x-intercept, plug in 0 for y into the formula.

x + 2y = -4

x + 2(0) = -4

x + 0 = -4

x=-4

This gives you an x-intercept of -4, which can be plotted at (-4, 0). Put those two numbers on the line and graph it, remembering that your slope is -1/2

Hope this helps!

Answer:

The standard form of such an equation is Ax + By + C = 0 or Ax + By = C. When you rearrange this equation to get y by itself on the left side, it takes the form y = mx +b. This is called slope intercept form because m is equal to the slope of the line, and b is the value of y when x = 0, which makes it the y-intercept.

Step-by-step explanation:

Given:

Jason buys three shirts with a listed price of $20 each.

He uses a coupon that provides "Buy Two, Get One Free".

To find:

The total final price Jason pays.

Solution:

Total number of shirts he buys = 3

Since he uses a coupon that provides "Buy Two, Get One Free", therefore he need to pay for 2 shirts and 1 he will get free.

Cost of 1 shirt = $20

Cost of 2 shirts = 2 × $20

                        = $40

Therefore, total final price Jason pays is $40.
