Witch expression is not equivalent to -3x-1/2+4y

....................

You have 2 points with the same x value of 2 and 2 points with the same y value of 4.

You now need 2 points with the same x value of 4 ( you are given 1) and 2 y values of 1 ( you are given 1.

The missing point would need to be (4,1)

The width would be x2-x1 = 4-2 = 2 units

The length would be y2-y1 = 4-1 = 3 units

Area = 3x 2 = 6 square units

y=mx+b

y-y1=m(x-x1)

Ax+By= C

Answer:

The answer is below

Step-by-step explanation:

a)

The area of the figure = sum of the area of the individual polygons

The area of the figure = x + 1 + y + 1 + x = 2x + y  + 2

The perimeter of the figure = sum of the length of the sides = 2(1 + (x + 1 + y + 1 + x)) = 2(2x + y + 3) = 4x + 2y + 6

b)

a)

The area of the figure = sum of the area of the individual polygons

The area of the figure = y² + xy + 1 + 1 + 1 = y² + xy + 3

The perimeter of the figure = sum of the length of the sides = (y + 1) + x + y + (y + 1) + y + 1 + 1 + 1 + x + 1 = 4y + 2x + 6

Answer:

With what?

Step-by-step explanation:

2x(x-1) = 2x - 2

Step-by-step explanation:

a thing my math teacher always taught that sticks is that the equals sign is essentially the words is the same as. Think of it this way the sentaxe would be 2x -2 is the same as 2x minus 2. we get this because initially with the parentheses we have to take the number outside which is 2 and multiply everything inside by it. 2 times x equals 2x and 2 times -1 is negative 2.

Answer:

12.5 sq. units

Step-by-step explanation:

Area of a Trapezoid Formula: (see the image attached)

7.5 + 2.5 = 10

10/2 = 5

5(2.5) = 12.5

So, the area of the trapezoid is 12.5 sq. units.

Answer:

274.05 (I assume they round it to A. 274.1)

Step-by-step explanation:

The figure seems to be comprised of 7 triangles, each of base 8.7 and height 9.

total area would be

7 * (8.7 * 9 / 2) = 7 * 39.15 = 274.05

Step-by-step explanation:

It is using time tables by x6

Answer:

The sample mean is of 1970 daily calories.

The margin of error is of 120 daily calories.

The sample standard deviation is of 12.3 daily calories.

Step-by-step explanation:

Mean number of daily calories consumed by participants in a medical study is (1850, 2090).

The sample mean is the mean of the bounds of the confidence interval. So

[tex]M = \frac{1850 + 2090}{2} = 1970[/tex]

The sample mean is of 1970 daily calories.

Margin of error:

The margin of error is the difference between the bounds and the sample mean. So

2090 - 1970 = 1970 - 1850 = 120

The margin of error is of 120 daily calories.

Sample standard deviation:

Now I have to expand a bit into the t-distribution. So

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 22 - 1 = 21

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 21 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.08

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}}[/tex]

In which s is the standard deviation of the sample.

Since [tex]M = 120, T = 2.08, n = 22[/tex]

[tex]120 = 2.08\frac{s}{\sqrt{22}}[/tex]

[tex]s = \frac{120}{2.08\sqrt{22}} = 12.3[/tex]

The sample standard deviation is of 12.3 calories.

Answer:

[tex]a^{2}(24a^{2}+36a+12)[/tex]

Step-by-step explanation:

Area of rectangle= Length*Width

so [tex](6a^{2}+9a+3)*4a^{2}[/tex]   multiply each coefficient of a times 4a^2

[tex]24a^{4}+36a^{3}+12a^{2}[/tex]  then take a^2 common factor so it will be

[tex]a^{2}(24a^{2}+36a+12)[/tex]=area

Answer:

380-5%

Step-by-step explanation:

Answer:

£399

Step-by-step explanation:

personally its easier to find 1% first then multiply it by how many percent are needed to be found.

380/100=1%

380/100=3.8

3.8x5=5%

3.8x5=19

380+19=usual price

380+19=199

Answer:

4 POUNDS OF FLOUR

Step-by-step explanation:

The number of cups of flour he added is 4.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Bowl weight = 1(1/2) pounds

Number of cups of flour weight = x pounds

Now,

Total weight = 2(3/4) pounds

1(1/2) + x = 2(3/4)

x = 11/4 - 3/2

x = (11 - 6)/4

x = 5/4

Now,

Weight of each cup of flour = 5/16 pounds

Now,

The number of cups of flour.

= 5/4 ÷ 5/16

= (5 x 16) / (4 x 5)

= 4

Thus,

The number of cups of flour is 4.

Answer:

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

Step-by-step explanation:

Given

[tex]5x^2 - 13xy + 8y^2 = 0[/tex]

Required

Find x/y

[tex]5x^2 - 13xy + 8y^2 = 0[/tex]

Expand

[tex]5x^2 -5xy - 8xy + 8y^2 = 0[/tex]

Factorize:

[tex]5x(x - y) - 8y(x - y) = 0[/tex]

Factor out x - y

[tex](5x - 8y)(x - y) = 0[/tex]

Divide both sides by [tex](x-y)[/tex]

[tex]5x - 8y = 0[/tex]

Add 8y to both sides

[tex]5x = 8y[/tex]

Divide both sides by 5

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

Divide both sides by y

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

Answer: 0.075

Step-by-step explanation: when you are working with percentages to decimals you want to move the decimal two places to the left. If you are working with decimals and you want to make it a percentage you would move the decimal two places to the right.

Answer:

7.5% = 0.075

Step-by-step explanation:

Whenever you're converting a percentage into a decimal, you multiply the percentage by 100, or move the decimal point two points to the left. So, 7.5% as a decimal is 0.075.
