x + 2y = 10
x + 3y = 15

Answer:

(2,0)

Step-by-step explanation:

2x-y=4 equation 1

3x+y=6 equation 2

5x=10 eliminate y by adding equations

x=2

solve for y

2x-y=4

2(2)-y=4

4-y=4

-y=0

y=0

check answer:

3x+y=6

3(2)+0=6

6=6

Answer:

100π m^2

Step-by-step explanation:

Given data

Diameter= 20m

Radius= 10m

The expression for the  area is

Area= πr^2

Area= π*10^2

Area= π*100

Area= 100π m^2

Hence the area is 100π m^2

Answer:

out of SOH, CAH, TOA we will sue TOA

tan(56)=10/x

tan(56)/10=1/x

10/tan(56)=x

x=6.745 which rounds to 6.7

Answer:

Free enterprise, also known as free market or capitalism, is an economic system driven by supply and demand. Private businesses and consumers control the marketplace with little to no interference from the government. In this type of system, the government does not have a central plan for the nation's economy.

Step-by-step explanation:

Answer

the diameter is 44

Step-by-step explanation:

the radius is just half of the diameter so to get the diameter from the radius just multiply it by two.

Answer:

In the picture

Step-by-step explanation:

First, find a function for each line.

-2x - 2 fits the green line because for every x value, y is -2(x) - 2.

2x + 1 fits the red line because for every x value y is 2(x) + 1.

You also need to include "if." -2x -2 if x < 0.

For the red line, the dot is closed so if x ≥ 0.

Answer:

[tex]Pr =0.75[/tex]

Step-by-step explanation:

Given

See attachment for wedge

Required

[tex]P(x > 5)[/tex]

The sample space of the wedge is:

[tex]S = \{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}[/tex]

[tex]n(S) = 20[/tex]

The outcomes greater than 5 are:

[tex]x > 5 = \{6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}[/tex]

[tex]n(x>5) =15[/tex]

So, the probability is:

[tex]Pr =\frac{(n(x>5)}{n(S)}[/tex]

This gives:

[tex]Pr =\frac{15}{20}[/tex]

[tex]Pr =0.75[/tex]

Answer:

$125

Step-by-step explanation:

if there was a discount of 20%, the sales price is 100 - 20 = 80% of the original price

let a = original price

this equation can be used to represent the question

a x 0.8 = 100 ]]divide both sides by 0.8

a = 100 / 0.8 = 125

Answer:

n

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given function in the question is,

[tex]f(x)=\frac{-2x^2-4x}{4x+8}[/tex]

       [tex]=\frac{-2x(x+2)}{4(x+2)}[/tex]

       [tex]=-\frac{1}{2}x[/tex] If [tex]x\neq -2[/tex]

Given function is not defined at x = -2

At x = -2,

[tex]f(-2)=\frac{1}{2}(2)[/tex]

          [tex]=1[/tex]

Therefore, there is a hole in the graph at (-2, 1).

Graph of the function 'f' will be a straight line with a hole at (-2, 1).

Horizontal asymptote → None

Vertical asymptote → None

x-intercept → No x-intercept [Line passes through origin (0,0)]

y-intercept → No y-intercept [Line passes through origin (0,0)]

Hole → (-2, 1)

Answer:

The first quartile is the median of the data points to the left of the median. The third quartile is the median of the data points to the right of the median. Step 4: Complete the five-number summary by finding the min and the max. The min is the smallest data point, which is 25.

Answer:

A = 78.5 ft

Step-by-step explanation:

D=10ft

R=D/2

R=5ft

A=πr²

A=π5²

A=π25

A=78.53982

A=78.5ft

Answer:

5 + 3.5h = 29.50

Step-by-step explanation:

The flat fee means that you will be paid the money with no change to it.

So you will not multiply it.

3.5h means that you are adding 3.50 every hour according to the question

So summary:

5+3.5h = 29.50

Evaluation:

5+3.5h = 29.50

24.50 = 3.5h

h = 7

Answer:

38°

Step-by-step explanation:

The angles in a triangle always add up to 180 degrees.

Therefore, all the angles in the triangle given in the question add up to 180 degrees.

So, let's create an equation and solve for [tex]x[/tex]:

[tex]x+44 + 63 + 85 + x = 180[/tex]

Simplify:

[tex]2x + 192=180[/tex]

Solving for [tex]x[/tex] we get:

[tex]2x=-12\\x=-6[/tex]

Now, let's put the value of [tex]x[/tex] we got into the formula for angle A.

[tex]x+44=y[/tex]

[tex]-6+44=y=38[/tex]
