Answer: [tex]\frac{6}{5}[/tex]x + 6

Step-by-step explanation:

       We will use the order of operations, also known as PEMDAS. See attached. Please note that we cannot do what is in the parentheses first because we have a variable, so we will distribute the 2 into it. Since this is an expression, I do not believe we can fully solve for x, but can only simplify.

       Given:

2(3/5x+3)

       Distribute:

2 * (3/5x) + (2 * 3)

6/5x + 6

       Answer:

The probability of pulling out a blue ball is 1/3

This is a likelihood or chance that an event will occur. Mathematically:

Probability = Expected/Total outcome

If someone randomly reaching into a bag of 8 red table tennis balls and 4 blue table tennis balls, the total outcome is:

Total outcome = 8 + 4 = 12 balls

If a blue ball is pulled out then the probability of pulling it out is:

Pr(blue ball) = 4/12 = 1/3

Hence the probability of pulling out a blue ball is 1/3

Answer:

y = ¼(x-4)

Step-by-step explanation:

Before solving the question, let's look at one example,

In this case, y is directly proportional to (x-4) means that y∝(x-4) which can also mean that y=k(x-4).

Hence, to find the value of k, substitute x=16, y=3 into y=k(x-4),

3=k(16-4)

k=3/12

k=1/4

After that, substitute the k value into the equation,

Answer:

increasing

increasing

decreasing

increasing

decreasing

neither

Step-by-step explanation:

"increasing" just means the graph is going up from left to right.

"decreasing" means going down from left to right.

"neither increasing nor decreasing" means flat, horizontal, not going up or down.

Imagine you are walking on the x-axis, starting on the left, the numbers on the axis are like house addresses as you walk down the street. The column that says "interval" is saying where you are looking at along the axis.

-7 < x < -3 means from -7 to -3 on the x-axis. That piece of the curve IS going up from left to right. From -3 to -1 is also going up, so its increasing. From -1 to 1 the graph goes down, that's decreasing. Then it goes up again, then down, then flat. (incr, decr, neither)

Any slanted line or curve can be seen as going up or going down, depending on which direction you are going. But in this case only consider left to right ONLY. Then you can tell if its increasing or decreasing.

Answer:

The correct answe is H , if yu sub the x value in each of the equations yu should get y

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex]

To find the slope of a line (m):

To find the y-intercept of a line (b):

We're given a set of coordinates for this linear relation.

First, solve for the slope.

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

⇒ Plug in any two points that fall on the line (in this case we used (-2,-7) and (2,1)):

[tex]m=\dfrac{1-(-7)}{2-(-2)}\\\\m=\dfrac{1+7}{2+2}\\\\m=\dfrac{8}{4}\\\\m=2[/tex]

Therefore, the slope of the line is 2. Plug this into [tex]y=mx+b[/tex]:

[tex]y=2x+b[/tex]

Now, let's solve for the y-intercept (b)

[tex]y=2x+b[/tex]

Plug in any of the given points:

[tex]1=2(2)+b\\1=4+b\\b=-3[/tex]

Therefore, the y-intercept of the line is 3. Plug this back into [tex]y=2x+b[/tex]:

[tex]y=2x-3[/tex]

Step-by-step explanation:

The solution of system of equations is (3.5, 3.5).

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

1) 1/2 (12x+8) -1/3 (24)=1/4 (16x+40)

6x+4-8=4x+10

6x-4=4x+10

6x-4x=10+4

2x=14

x=7

Therefore, the value of x is 7.

3) y=3x-7 -------(i) and -y=x-7 -------(ii)

Substitute equation (i) in equation (ii), we get

-(3x-7)=x-7

-3x+7=x-7

x+3x=7+7

4x=14

x=14/4

x=3.5

Substitute x=3.5 in equation (i), we get

y=3×3.5-7

y=10.5-7

y=3.5

So, the solution is (3.5, 3.5)

4) Production of chairs from Anthony

(2, 10) and (5, 25)

Here, m=(25-10)/(5-2)

= 15/3

= 5

Substitute m=5 and (x, y)=(2, 10) in y=mx+c, we get

10=5(2)+c

c=0

Substitute m=5 and c=0 in y=mx+c, we get y=5x

Production of chairs from Billy

(1, 2) and (4, 8)

Here, m=(8-2)/(4-1)

= 6/3

= 2

Substitute m=2 and (x, y)=(1, 2) in y=mx+c, we get

2=2(1)+c

c=0

Substitute m=2 and c=0 in y=mx+c, we get y=2x

When y=18

Production of chairs from Billy 18=5x

x=3.6

When y=18

Production of chairs from Anthony

18=2x

x=9

Therefore, the solution of system of equations is (3.5, 3.5).

Answer:

The equation is y = x-2

The equation of the line will be y = x - 2.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

The slope of the line is,

[tex]m = \dfrac{y_2-y_1}{x_2-x_1}[/tex]

From the given table consider the two points as,

( 14, 12 )

( 13, 11 )

The slope is calculated as,

[tex]m = \dfrac{12 - 14}{11-13}[/tex]

m = 1

The y-intercept is calculated as,

y = mx + c

y = x + c

12 = 14 + c

c = -2

The equation of the line can be written as,

y = mx + c

y = x - 2

The vertex would be (-3, -1)

Step-by-step explanation:

Since this is in vertex form already, a(x-h)^2+k  where h is the x value of the vetex, and k is y.

We would take the opposite of +3 and get -3, which gives us our x cordinate.

We don't change the k value, so it just stays -1, giving us our y value.

Therefore, the vertex is at (-3, -1)

Answer:

21.5 square m

Step-by-step explanation:

You find the area of the shaded space by finding the area of the square and the removing the area of the circle.

The area for the square is 10x10=100.

All you have to do is follow the formula, (3.14)r^2. However, the 10 is NOT the diameter! The radius is half of the diameter. So, it's 3.14x5x5, which is 3.14x25=78.5.

Then, you can do 100-78.5=21.5
