Which lines are parallel? How do you know?

Answer:

y = 4

Step-by-step explanation:

y ∝ x

y = kx (k is constant)

when y = 12 and x = 3

y = kx

=> 12 = k*3

∴ k = 4

when x = 1 and k = 4

y = kx

  = 4*1

   = 4

Answer:

a. Breakfast is 10 & Lunch is 15

Step-by-step explanation:

25 = 50%

x = 30%

y = 20%

1% = 0.5 because 25/50= 0.5

0.5 x 30 = 15 and 0.5 x 20 = 10

The percent of change in the price of a cellphone from 2010

to today is 58.33%

The price of cellphone was $240 in 2010.

While the price of cellphone presently is $380.

The percent of change in the price of a cellphone from 2010  to today is:

Percent change in price = [(380 - 240)/240] * 100%

Percent change in price = 58.33%

Hence, The percent of change in the price of a cellphone from 2010

to today is 58.33%

Step-by-step explanation:

Distance formula: (see attached file) pythogorean rule

is the squared coordinates x added to squared coordinates of y

X- coordinates: -5 & -9

Y- coordinates: -5 & -2

Substitute into equation:

[tex]distance = \sqrt{ ( - 5- - 9)^{2} + ( - 5 - - 2)^{2} } = 5[/tex]

Answer:

The indicated z-score is 1.77

Step-by-step explanation:

procedure  finding the z-value is listed below:

1.From the table of the standard normal distribution, locate the probability value as 0.9616.

2.Move left until the first column is reached. Note as 1.7.

3.Move upward until the top row is reached. Note as 0.07.

4.Locate the probability value, by the intersection of the row and column values, gives the area to the left of z = 1.77

SEE THE FORMULA BELOW.

Answer:

See below

Step-by-step explanation:

The test is one-tailed (left-tailed in this case) because you are trying to prove that the true proportion is less than the proposed proportion of 11%

The test statistic, z, is given to us as z=-1.34 when rounded to 2 decimal places.

The p-value, p, is given to us as p=0.0908 when rounded to 4 decimal places.

The null hypothesis is [tex]H_o:p<0.11[/tex] because the original claim was that the proportion was less than 11%.

Answer:B. 17%

A.83%

B.17%

C.20%

D.10%

The unemployment rate in this hypothetical country is equal to 17%.

First of all, we would determine the percentage of people that are employed and then subtract this percentage from the total percentage of 100%.

The table below gives the complete information about the population and employment numbers for a hypothetical country:

Mathematically, employment rate can be calculated by using this formula:

[tex]Employment\;rate = \frac{Employed}{Labor\;force} \times 100\\\\Employment\;rate =\frac{500}{600} \times 100\\\\[/tex]

Employment rate = 83.3 ≈ 83%.

For the unemployment rate, we have:

Unemployment rate = 100 - 83

Unemployment rate = 17%.

Step-by-step explanation:

9x - y

9*7 - (-2)

63 + 2

65

Answer:

fg(x)=f(g(x)

=f(x-5)

But ;f(x)=x+2

f(x-5)=(x-5)+2

=x-5+2

fg =x-3

gf(x)=g(f(x))

=g(x+2)

But ;

g(x)=x-5

g(x+2)=(x+2)-5

=x+2-5

=x-3

g(g)=g(x-5)

g(x-5)=(x-5)-5

=x-5-5

=x-1

Answer:

(2x - 3)(x + 9)

Step-by-step explanation:

A = 2

B = 15

C = -27

when we plug these numbers into the equation  (Ax^2 + Bx + C) we get

2x^2 + 15x - 27

using the "X" method we have to multiply the A term and C term together

so -27 x 2 = -54

so we have to find factors of -54 that also add to the middle term, 15

- 3 and 18 add to 15 but also multiply to -54 so we can add these numbers into the X (refer to drawing)

Answer:

260 Downloads

Step-by-step explanation:

s = number of standard downloads

3s = number of high-quality downloads

2.9s + 4.6(3s) = 4342

2.9s + 13.8s = 4342

16.7s = 4342

s = 260

The standard version was downloaded 260 times and the high-quality version was downloaded 780 times.

Answer:

you can write the equation of any line in the form of y = mx + b .

Step-by-step explanation:

Answer:

[tex]y = - \frac{1}{6} x + 2[/tex]

Step-by-step explanation:

Slope-intercept form

y= mx +c, where m is the slope and c is the y-intercept.

Let's first identify the coordinates of two points on the graph:

(-6, 3) and (6, 1)

[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]

Slope

[tex] = \frac{3 - 1}{ - 6 - 6} [/tex]

[tex] = \frac{2}{ - 12} [/tex]

[tex] = - \frac{1}{6} [/tex]

Substitute the value of the slope into m in the equation:

[tex]y = - \frac{1}{6} x + c[/tex]

To find the value of c, substitute a pair of coordinates into the equation.

When x= 6, y= 1,

[tex]1 = - \frac{1}{ 6} (6) + c[/tex]

1= -1 +c

c= 1 +1

c= 2

Thus, the equation of the line is y= -⅙x +2.

The y-intercept can also be derived from the graph as we can see that the line passes through the y- axis at (0, 2). This point can also be used to find the slope of the line too.

Answer:

Step-by-step explanation:

It's an acute angle. Acute, in this case, means anything between 0 and 90 written 0<x<90. Notice that you are using < and not ≤. The endpoints are not included. They have their own names. 90 is a right angle. 0 is called a zero degree angle.

Answer: y=(10/9)x+19

Step-by-step explanation:

The slope intercept form is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).

We are given the slope, m:

y=(10/9)x+b

To find b, enter the given point (0,19) and solve for b:

y=(10/9)x+b

19=(10/9)*(0)+b

b = 19

So we have y=(10/9)x+19
