Answer:

y=-23/7;y=-19/7;y=-15/7

Step-by-step explanation:

when x is -2 then y is;

2(-2)-7y=19

-4-7y=19

-7y=23 divide both sides by -7

y=-23/7

when x=0 then y is;

2(0)-7y=19

-7y=19

y=-19/7

when x=2 then y is;

2(2)-7y=19

4-7y=19

-7y=15

y=-15/7

Answer:

Divide both sides by -60. Note: when you divide an inequality by a negative number, switch the direction of the sign.

x<-10/60

x<-1/6

Answer:

y = -6/5x + 3

Step-by-step explanation:

You need to find the slope of the line (m) and the y-intercept of the line (b) to fill out the easiest equation of the line formula: y = mx + b. You already know b because it was given to you in one of the points! The point where x = 0 is your y intercept, which is given as (0, 3) here, so your b = 3. For m, take the difference of the y values in the points and divide them by the difference of the x values in the points. (-3-3)/(5-0) = -6/5.

Plug your values in to get y = -6/5x + 3, and you're done!

Step-by-step explanation:

4x+12=6x-14

Divide by 2

2x+6=3x-7

2x-3x=-7-6

-x=-13

x=13

m<1

4x+12

4(13)+12

52+12

64

64+64+y+y=180

divide by 2

64+y=90

y=90-64

y=26

Answer:The scatter plot shows the number of years of experience, x, and the hourly pay rate, y, for each of 24 cashiers in California.(a) Write an approximate equation of the line of best fit for the data. It doesn't have to be the exact line of best fit.(b) Using your equation from part (a), predict the hourly pay rate for a cashier with 18 years of experience.

The first quartile is 4.5.

The third quartile is 27.5.

A quartile divides data into three points: lower, middle, and upper quartiles, resulting in four groupings of the dataset. The lower quartile, or first quartile, is designated as Q1 and is the 9 halfway number between the dataset's lowest and median values. The median is also in the second quartile, Q2. The upper or third quartile, abbreviated as Q3, is the center point of the distribution that sits between the median and the highest value.

In the question, we are given the number of incidents in which police were needed for a sample of 9 schools in Allegheny County is 8, 39, 6, 12, 45, 16, 3, 0, 15.

We are asked to find the first and the third quartile for the data.

We first arrange the data in ascending order as follows:

0, 3, 6, 8, 12, 15, 16, 39, 45.

We have 9 data points.

Thus, the first quartile is the data at the point (9 + 1)/4 th observation,

or, the first quartile is the data at the point 2.5th observation,

or, the first quartile is the data at the average of 2nd and 3rd observation, = ( 3 + 6 )/2 = 4.5.

Thus, the first quartile is 4.5.

Thus, the third quartile is the data at the point 3(9 + 1)/4 th observation,

or, the third quartile is the data at the point 7.5th observation,

or, the third quartile is the data at the average of 7th and 8th observation, = ( 16 + 39 )/2 = 27.5.

Thus, the third quartile is 27.5.

Step-by-step explanation:

Given 3x - 2 <2x +1 3x -2x 1 + 2 x <3 or x∈(−∞,3)

The lines y=3x−2 and y=2x+1 both will intersect at x=3

Clearly, the dark line shows the solution of 3x−2<2x+1.

Answer:

Step-by-step explanation:

We can find the distance by using the distance formula.

d= √(x2-x1) ² + (y2-y1)²

For points (x1 = 2, y1 = -6) and ( x2 = -3, y2 = 6)

d= √(-3-2)² + (6 -(-6))², add and subtract what is inside of the parenthesis

d= √(-5)² + ( 12)², square the positive and negative number and get a positive

d= √25 + 144, add the numbers under the square root

d = √169, use the fact that 13*13= 169 to solve the square root

d= 13

Answer:

0.064

Step-by-step explanation:

If 0.64 is ten times as much as something, then the thing you're looking for is 10 times as small as 0.64, meaning you need to divide 0.64 by 10. Doing so will give you 0.064.
