Answers

Let's reorder the equation. -4x+2x-3-6. Now we can reduce like terms. -4x+2x= -2x and -3-6= -9. Put the two back together and it is simplified to -2x-9.

The number of hours a group of contestants spent preparing for a quiz show are listed below. What is a frequency table that represents the data? 60 25 86 56 45 48 90 75 30 67 90 36 80 15 32 65 61C

Answers

Answer:

Step-by-step explanation:

Given in the number of hours a group of contestants spent preparing for a quiz

The list shows as follows:

60 25 86 56 45 48 90 75 30 67 90 36 80 15 32 65 61

In ascending order this becomes

x     15 25 30 32 36 45 48 56 60 61 65 67 75 80 86 90

F      1    1     1    1    1    1    1    1    1    1   1    1    1    1     1    2

Thus we have mode =90

All other entries have frequency 1 except 90
60 25 86 56 45 48 90 75 30 67 90 36 80 15 32 65 61

Which set of ordered pairs (x, y) could represent a linear function?A = {(-6,3), (-3,0), (0, -3), (3,-5)}
B= Y(-1,2), (2, 1), (5,0), (8, -1)}
C = {(-4,-7), (-1, -3), (2.0), (5,3)}
D = {(-5, -8), (-2,-4), (1,1), (4,6)}

Answers

Set of ordered pairs (x, y) could represent a linear function

B= {(-1,2), (2, 1), (5,0), (8, -1)}

Option B is correct

Linear Function

Linear function is a function whose graph is a straight line .

Slope

Slope of a line tells us how steep the line is . Slope of a line is same at all the points.

Slope formula is (y_2-y_1)/(x_2-x_1)

Lets find out slope of any two points in each option

A = {(-6,3), (-3,0), (0, -3), (3,-5)}

(0-3)/(-3+6) =-1\n(-5+3)/(3-0) =-(2)/(3) \n

Slopes are not same

Lets check the second option

B={(-1,2), (2, 1), (5,0), (8, -1)}

(1-2)/(2+1) =(-1)/(3) \n(0-1)/(5-2) =(-1)/(3) \n(-1-0)/(8-5) =(-1)/(3) \n

The slope of any two points are equal .

slope are same . So it represents a linear function .

C = {(-4,-7), (-1, -3), (2.0), (5,3)}

slope =(-3+7)/(-1+4)=(4)/(3) \nslope =(0+3)/(2+1)=(3)/(3)=1

Slopes are not same . So it is not a linear function

D = {(-5, -8), (-2,-4), (1,1), (4,6)}

slope = (-4+8)/(-2+5)= (4)/(3) \nSlope = (1+4)/(1+2)= (5)/(3) \n\nslope = (6-1)/(4-1)= (5)/(3) \n

Slopes are not same . so it is not a linear function .

Option B is correct.

A line that passes through the point (–1, 3) has a slope of 2. Find another point on the line.a. (–3, 2)
b. (1, 4)
c. (1, 5)
d. (0, 5)

Answers

Using the slope-intercept form of a line, the equation can be generated
y = mx + b

m = 2
and we can solve for b by substituting the given coordinates where the line passes through
3 = 2(-1) + b
b = 5

So, the equation of the line is
 y = 2x + 5

Trying the options using the equation, the answer is
d. (0,5)
