write an equation in slope intercept form of the line that passes through the points (-3,6) and (0,0)
Answers
Answer:
y=-2x
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(0-6)/(0-(-3))
m=-6/(0+3)
m=-6/3
m=-2
y-y1=m(x-x1)
y-6=-2(x-(-3))
y-6=-2(x+3)
y=-2x-6+6
y=-2x
Note that the slope-intercept form is y=mx+b where m=slope and b=y-intercept.
The car travels 60 km from city A to city B passed at speed x. On the way back, the speed was increased by 12 km / h. What is the initial speed if the car has traveled for a total of 10 hours?
Answers
Answer:
54 km/h
Step-by-step explanation:
use s=½(u+v)t
600=½(x+x+12)10
600=½(2x+12)10
600=(2x+12)5
600=10x+60

A student wants to check six websites. Four of the websites are social and two are school-related. After checking just two sites, she has to leave for school. What is the approximate probability that she checked a social website first, then a school-related website? 0. 042 0. 267 0. 533 0. 667.
Answers
The approximate probability that she checked a social website first, then a school-related website is 0.267.
First step is to calculate the Total number of websites
Total number of websites=Number of school websites+Number of social websites
Total number of websites=2+4
Total number of websites=6
Second step
Probability of checking the social website first
Probability of checking social website=Number of social websites/Total number of websites
Probability of checking social website= 4/6
Third step
Since one social website is checked which means that she is left with 3 social website and 2 school websites
Total number websites=2+3
Total number websites=5
Forth step
Probability of checking social website=Number of school websites/Total number websites
Probability of checking social website=2/5
Fifth step
Probability= 4/6 x 2/5 = 0.2666
Probability=0.267(Approximately)
Inconclusion the approximate probability that she checked a social website first, then a school-related website is 0.267.
Learn more about probability here:https://brainly.com/question/25688842
Answer:
0.267
Step-by-step explanation:
Total websites = school websites (2) + social websites (4) = 6
Checking social website = social websites (4) /Total websites (6) = 2/3
Total websites is 5
Checking social website = school websites (2) /Total websites (5)
4/6 x 2/5 = 0.2666
Answer: 0.267

Second one:
Function? No
Domain : { 2 , 3 }
Range : { 10 , 13 , 16 }
Third one :
Function ? No
Domain : { 33 , 35 , 36 }
Range : { 8 , 10 }
Step-by-step explanation:
A function is a relation where each input has its own output. In other words a function is a relation where each x value has its own y value. If an x value repeats the relation is not a function.
The domain is the set of x values in a relation whereas the range is the set of y values in a relation
For the first one. No x value repeats, each input has its own output therefore this is a function.
Domain : { -1 , -2 , -3 }
Range { 10 , 13 , 16 }
The second one : The x value 2 repeats therefore the relation is not a function.
Domain : { 2 , 3 }
Range : { 10 , 13 , 16 }
The third one : Each x value has its own y value therefore this relation is a function. ( Note that y values are allowed to repeat )
Domain : { 33 , 35 , 36 }
Range : { 8 , 10 }

The value of x in the expression is 55/2 or 27½
From the question given above, we obtained:
(x – 3)2 = 49The value of x can be obtained as follow:
(x – 3)2 = 49
Clear the bracket
2x – 6 = 49
Collect like terms
2x = 49 + 6
2x = 55
Divide both side by 2
x = 55 / 2 or 27½
Thus, the value of x is 55/2 or 27½

Answers
Answer:
see attached
Step-by-step explanation:
boundary line
When graphing, it can be useful to have the equation in slope-intercept form. You can get that by solving for y.
4y ≤ -5x -4 . . . . subtract 5x from both sides
y = -5/4x -1 . . . . divide both sides by 4
This tells you the slope is -5/4, and the boundary line crosses the y-axis at y = -1. The slope is the ratio of rise to run, so -5/4 tells you the line will go down 5 units for each 4 unit to the right. That is, points (4, -6) and (-4, 4) will be on the line.
line type and shading
The "or equal to" part of the inequality symbol (≤) tells you that the boundary line will be solid, not dashed.
The "less than" part of the symbol tells you that the values of x and y are less than those on the boundary line, so shading will be to the lower-left. The graph is shown in the attachment.
_____
Additional comment
You can determine the location of the shading by looking at any variable term that has a positive coefficient, and its relation to the inequality symbol. Here, that could be either of ...
5x ... ≤ ...4y ... ≤ ...These tell you that x- and y-values in the solution set are less than those on the line, so shading will be left of (x<) or below (y<) the line. (In rare cases where all of the variable coefficients are negative, you can multiply the equation by -1 and reverse the inequality before you make this analysis.)
