Answer:

y=-x+4

The equation is in the form y=mx+c, where m is the slope and c is the y-intercept, so we know that the slope (m) is -1, and the y-intercept (c) is 4.

The y-intercept is the value of y when x=0. So you can mark (0,4) as a point on the line.

The next thing I would do is take any value for x and find another point on the line. Let's let x=2:

y=-2+4

y=2

So now we know another point on the line (2,2). Mark this on the graph too.

Then connect these two points and extend to the line to finish off your graph, and you're done!

(PS: if the whole 'y-intercept' thing gives you a headache, you can just pick any two values for x, sub them in to find the points, mark those points and connect. There's also a method for graphing using just the slope and y-intercept, but the method above is usually what people prefer to do)

I've attached a sketch that corresponds to my answer to give you an idea:

Answer: 135/pi

Step-by-step explanation: Circumference is 16pi. So then 6/16pi is the fraction of the 360 arc measure of the entire circle that is the angle measure of the arc, so we multiply 6/16pi times 360 and yield 135/pi. Hope this helps!

- you can substitue x and y for 1, or 0 and graph each point

- use desmos and copy it

- depending on the type of equation find the x-intercept, y-intercept, vertex and then draw a line between them

Answer:

39-11=28 so that means X=39

Step-by-step explanation:

all you have to do is add 28+11 which would give you 39 and 39-11+28 and thats your answer

Answer:

x = 39

Step-by-step explanation:

step 1.

Add 11 to both sides

x - 11 = 28

x - 11 + 11 = 28 + 11

step 2. Add the numbers

− 1 1 + 1 1 = 2 8 + 1 1 x{\color{#c92786}{-11}}+{\color{#c92786}{11}}=28+11 x−11+11=28+11 = 2 8 + 1 1 And you'll get 39!

Answer:

2 sheets, or at least 1.34.

Step-by-step explanation:

What we need to do, is figure out the exact area of the window, and the area of the paper sheets. Then, we must convert meters to centimeters, in order to be correct.

Consider R to be the total area of the window.

Consider A to be the area of each sheet of paper.

3.55m * 2.28m = R

8.094m = R

21.6cm * 28cm = A

604.8cm = A

Now, we should convert meters to centimeters.

8.094m = 809.4cm

Then we'd divide to find out how much paper will be required

809.4 ÷604.8 = ≈ 1.34

So, they'll need want to have at least 1.34 sheets of paper, which isn't too unrealistic, but if we're looking for whole sheets, then they will need 2 sheets of paper.

Step-by-step explanation:

Answer:

m2 =1/4

Step-by-step explanation:

m1 . m2 = 1

m1 is given 4 then

4.m2 =1

4.m2/4 =1/4

m2 = 1/4

Hello there!

The slopes of perpendicular lines are opposite reciprocals.

So, if one line has a slope of 4, then the slope of the line perpendicular to it is the opposite of 4 flopped over (-1/4)

And we're done! Hope it helps you!

we would like to Prove the following for x=1:

[tex] \displaystyle {x}^{2} - x = 0[/tex]

since x=1 substitute:

[tex] \displaystyle {1}^{2} - 1 \stackrel {?}{=}0[/tex]

to simplify it we can consider the order of PEMDAS which is a abbreviation of

since exponent come first

simplify exponent:

[tex] \displaystyle {1}^{} - 1 \stackrel {?}{ = }0[/tex]

simplify substraction:

[tex]\displaystyle 0 \stackrel { \checkmark}{ = }0[/tex]

since left hand side equal to right hand side

hence, Proven

use a²-b²=(a+b)(a-b) to rewrite:

[tex] \displaystyle (x + \sqrt{x} )(x - \sqrt{x} ) = 0[/tex]

since x=1 substitute:

simplify square root:

simplify parentheses:

Multiplying any number by 0 results 0 thus

since left hand side equal to right hand side

hence, Proven

Given,

x = 1

We need to find if x² - x = 0 is true or false.

If x = 1, then x² will be equal to 1² = 1 (1 multiplied by 1 is one / 1 square is equal to 1)

So,

By substituting ...

=》1² - 1 = 0

Now calculate...

Answer:

74.2

Step-by-step explanation:

First think of a whole circle. The area of a circle is pi*r^2., which is 81 pi. Then the fraction of the circle is 105/360. Times this by 81 pi and you get about 74.2 and that is the answer.

Answer:

Mean = 2.40

Standard deviation = 1.356

Step-by-step explanation:

Given the data:

X :___ 0 __1 ___ 2 ___ 3 __ 4 __ 5 __Total

P(x)_0.02_0.31_0.25_0.19_0.13 _0.10_ 1.00

The mean [E(X)]

Σx*p(x)

(0*0.02)+(1*0.31)+(2*0.25)+(3*0.19)+(4*0.13)+(5*0.10) = 2.4

The standard deviation :

Std(x) = sqrt[VAR(x)]

Var(x) = ((0^2 * 0.02)+(1^2 * 0.31)+(2^2 * 0.25)+(3^2 * 0.19)+(4^2 * 0.13)+(5^2 * 0.10)) - 2.4^2

Var(X) = 7.6 - 5.76 = 1.84

Std(X) = sqrt(1.84) = 1.356 (3 decimal places)

The area of the school is about 827 m² less than the area of the museum.

Area is the amount of area occupied by an object's flat (2-D) surface or shape.

Given:

Sammy finds satellite images of a school and a museum. They put the images on a coordinate grid (shown below).

School coordinate values are in meters.

To find the area of the school:

The school is rectangular.

Area of the rectangle = length x width

To find the length,

use distance formula.

We interpreted coordinates,

Fort length (-20, 20) and (-40, 80)

For width (-50, 10) and (80, -20)

Distance of length = √(60)²+(-20)² = 20√10

Distance of width = √(30)²+(10)² = 10√10

Area of the rectangle = length x width

Area of the rectangle = 20√10 x 10√10 = 2000 m²

The area of the museum is πr².

And r = 30

The area of the museum  =  π(30)². ≈ 2827 m².

Subtracting the area's = 827 m².

Therefore, the area of the school is about 827 m² less than the area of the museum.

Answer:

7/16 of the shoes were either sandals or clogs.

Step-by-step explanation:

Find a CD, which is 16.

Because we multiplied the denominator, we multiply the numerator as well.

3/8 becomes 6/16.

Now, because both of the denominators are the same, we are free to add both of the fractions together.

6/16 + 1/16 = 7/16.

Because this fraction isn't reducible, the answer will be 7/16.
