Answer:

y = - 2x + 9

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 9) and (x₂, y₂ ) = (4, 1) ← 2 points on the line

m = [tex]\frac{1-9}{4-0}[/tex] = [tex]\frac{-8}{4}[/tex] = - 2

The line crosses the y- axis at (0, 9 ) ⇒ c = 9

y = - 2x + 9 ← equation of line

Answer:

50% value change.

Step-by-step explanation:

A 100% increase from 10 would be 20. It's the equivalent of doing 10 times 2. We need 15 though which is half the distance in value to 10 than 20 is. Half of 100% is 50%.

Therefore, $15 is a 50% percent change from $10.

Answer:

The total distance in miles at x = 2 hours will be 543.2 miles.

Step-by-step explanation:

Given

Given the linear model function

y = -67.9x +679

where

y represents the distance, in miles y, is a function of time, x, in hours

To determine:

Use the model to calculate the total distance, in miles, at x = 2 hours

substituting x = 2 in the function

y = -67.9x +679

y = -67.9(2) +679

y = -135.8 + 679

y = 543.2 miles

Therefore, the total distance in miles at x = 2 hours will be 543.2 miles.

Answer:

543.2

Step-by-step explanation:

Answer: m^3

Step-by-step explanation:

Taking the square root of something is the same as raising it to the half power the square root of 4 is equal to 4^(1/2). This hold true with any root, not just square root. M^(3b) to the b root is equal to m^(3b x (1/b)). Ignore the base (m) for a second and the exponents make 3b x (1/b) which equals (3b/b). The b on the top and bottom cancel and you’re left with a 3. The answer is m^3

Answer:

[tex]x=\{0,\frac{\pi}{2},\pi,\frac{3\pi}{2}\}[/tex]

Step-by-step explanation:

Trigonometric Equations

Solve

[tex]3\sin 2x=0[/tex]

for x in [0,2π].

Dividing by 3:

[tex]\sin 2x=0[/tex]

Solving for 2x by using the inverse sine function:

[tex]2x=\arcsin (0)[/tex]

There are two angles in the first turn of the trigonometric circle whose sine is 0:

2x=0

2x=π

Dividing by 2, we get the first two solutions:

x = 0

[tex]x=\frac{\pi}{2}[/tex]

Since the argument of the sine is double, we look for solutions in the next turn of the circle, that is:

[tex]2x=2\pi[/tex]

[tex]2x=3\pi[/tex]

Again, dividing by 2:

[tex]x=\pi[/tex]

[tex]x=\frac{3\pi}{2}[/tex]

No more solutions can be found, thus the solutions are:

[tex]\mathbf{x=\{0,\frac{\pi}{2},\pi,\frac{3\pi}{2}\}}[/tex]

Answer:

[tex] \frac{x - 4}{x - 3} [/tex]

Step-by-step explanation:

[tex] \frac{ {x}^{2} - 8x + 16 }{ {x}^{2} - 7x + 12} [/tex]

Lets split the numerator and denominator.

[tex] = > \frac{ {x}^{2} - 4x - 4x + 16}{ {x}^{2} - 3x - 4x + 12} [/tex]

Lets factorise the numerator and denominator.

[tex] = > \frac{x(x - 4) - 4(x - 4)}{x(x - 3) - 4(x - 3)} [/tex]

[tex] = > \frac{(x - 4)(x - 4)}{(x - 3)(x - 4)} [/tex]

Cancelling x - 4 from numerator and denominator ,

[tex] = > \frac{x - 4}{x - 3} [/tex]

Answer:

[tex]Surface\ Area = 179.25cm^2[/tex]

Step-by-step explanation:

Given

See attachment for figure

Required

Determine the surface area

To do this, we calculate the surface area of each individual shape.

For the semicircle.

[tex]Area = \frac{1}{2}\pi r^2[/tex]

Here, the diameter (D) is given

[tex]D = 10cm[/tex]

The radius is:

[tex]r = \frac{1}{2}D[/tex]

[tex]r = \frac{1}{2}*10cm[/tex]

[tex]r= 5cm[/tex]

So, the area is:

[tex]Area = \frac{1}{2} * 3.14 * (5cm)^2[/tex]

[tex]Area = \frac{1}{2} * 3.14 * 25cm^2[/tex]

[tex]Area = 39.25cm^2[/tex]

For the triangle, the area is:

[tex]Area = \frac{1}{2}bh[/tex]

[tex]Area = \frac{1}{2} * 10cm * 8cm[/tex]

[tex]Area = 40cm^2[/tex]

For the rectangle

[tex]Area = Length * Width[/tex]

[tex]Area = 20cm * 5cm[/tex]

[tex]Area = 100cm^2[/tex]

So, the surface area is:

[tex]Surface\ Area = 39.25cm^2 + 40cm^2 + 100cm^2[/tex]

[tex]Surface\ Area = 179.25cm^2[/tex]

Answer

y=-4x-1

Step-by-step explanation:

Answer:

The answer is A

Step-by-step explanation:

The reason A is correct is because all of the other transformations change the size of the triangle, and A is the only answer that only reflects the image over the y axis without changing it, thus making it similar to the preimage

Given:

The data set is

10, 10, 11, 12, 13, 13, 13, 14, 14, 15, 15, 15, 16, 17, 17, 17, 35

To find:

Effect on mean, median, range after removing the outlier, 35.

Solution:

We have, the data set

10, 10, 11, 12, 13, 13, 13, 14, 14, 15, 15, 15, 16, 17, 17, 17, 35

[tex]\text{Mean}=\dfrac{\text{Sum of observations}}{\text{Number of observations}}[/tex]

[tex]\text{Mean}=\dfrac{10+10+11+12+13+13+13+14+14+15+15+15+16+17+17+17+35}{17}[/tex]

[tex]\text{Mean}=\dfrac{257}{17}[/tex]

[tex]\text{Mean}=15.117647[/tex]

[tex]\text{Mean}\approx 15.12[/tex]

Mean of the data set is 15.12.

[tex]Median=\dfrac{n+1}{2}\text{th term}[/tex] because n=17, which is odd.

[tex]Median=\dfrac{17+1}{2}\text{th term}[/tex]

[tex]Median=\dfrac{18}{2}\text{th term}[/tex]

[tex]Median=9\text{th term}[/tex]

[tex]Median=14[/tex]

Median is 14.

[tex]Range=Maximum-Minimum[/tex]

[tex]Range=35-10[/tex]

[tex]Range=25[/tex]

Range is 25.

After removing the outlier, 35, the data set is

10, 10, 11, 12, 13, 13, 13, 14, 14, 15, 15, 15, 16, 17, 17, 17

[tex]\text{Mean}=\dfrac{10+10+11+12+13+13+13+14+14+15+15+15+16+17+17+17}{16}[/tex]

[tex]\text{Mean}=\dfrac{222}{16}[/tex]

[tex]\text{Mean}=13.875[/tex]

Mean of the new data set is 13.875, which is less than 15.12.

[tex]Median=\dfrac{\dfrac{n}{2}\text{th term}+(\dfrac{n}{2}+1)\text{th term}}{2}[/tex] because n=16, which is even.

[tex]Median=\dfrac{\dfrac{16}{2}\text{th term}+(\dfrac{16}{2}+1)\text{th term}}{2}[/tex]

[tex]Median=\dfrac{8\text{th term}+9\text{th term}}{2}[/tex]

[tex]Median=\dfrac{14+14}{2}[/tex]

[tex]Median=\dfrac{28}{2}[/tex]

[tex]Median=14[/tex]

New median is 14, which is same as original median.

[tex]Range=17-10[/tex]

[tex]Range=7[/tex]

So, the new range is 7 which is less than 25.

Therefore, the mean of the data set will decrease, the median of the data set will not change, the Range of the data set will decrease.

[tex] \frac{1}{2} y - 9 > 1[/tex]

[tex] \frac{y}{2} - 9 > 1[/tex]

[tex] \frac{y}{2} > 1 + 9 \\ \frac{y}{2} > 10 \\ y > 10 \times 2 \\ y > 20[/tex]

We have to compare and consider both values which are y = 20 and any greater than 10 which is 21.

Substitute y = 20 in the Inequality.

[tex] \frac{20}{2} - 9 > 1 \\ 10 - 9 > 1 \\ 1 > 1 \longrightarrow \sf{false}[/tex]

Substitute y = 21 in the Inequality.

[tex] \frac{21}{2} - 9 > 1 \\ 21 - 18 > 2 \\ 3 > 2 \longrightarrow \sf{true}[/tex]

That means the value of y must be greater than 20. Hence the answer is B choice.

[tex] \large \boxed{y > 20}[/tex]

Answer: Scalene triangle

Step-by-step explanation:

A Scalene triangle has all of its three lengths to be different. The traingle above can not be an equilateral triangle too because all the sides aren't equal.

Also, it's not an isosceles triangle since two of its sides are not thesame. It's not a right angle triangle as the square of the hypothenuse isn't equal to the addition of the square of the other two sides.

Answer:

D

Step-by-step explanation:

First, find out how many more sandwiches he sells after 1 minute. To do this, you can look at the table and see that in 3 minutes, he sells 6 sandwiches. This means that in 1 minute, he will sell 2 sandwiches. In the equation, this will be s = 2t + something. To find out what the "something" is, substitute two values from the table and see what it has to be for the equation to be true.

For example, you can use time = 3 and sandwiches = 19

In the equation this would be

19 = 2 * 3 + something

19 = 6 + something

So that value would be 13.

The linear function is s = 2t + 13

Answer:

Yes, (2, 10) is a solution to this system:

y = 4x + 2

y = x + 8

Step-by-step explanation:

When graphed, the two equations cross at (2,10) making it a solution.

Answer:

Yes

Step-by-step explanation:

If y=4x+2 and y=x+8, then 4x+2=x+8

4x+2=x+8

4x=x+6

3x=6

x=2

Plugging this into the original equation "y=x+8", we obtain the result that y=10.

This means, (2, 10) is a solution  to the system.
