<h3>Answer: Choice B) </h3><h3>-6x - 2y = 12</h3>
===============================================
Explanation:
The x intercept is (-2,0) which is where the graph crosses the x axis.
The y intercept is (0,-6) which is where the graph crosses the y axis.
-----
Find the slope of the line through those two points
m = (y2-y1)/(x2-x1)
m = (-6-0)/(0-(-2))
m = (-6-0)/(0+2)
m = -6/2
m = -3
-----
The y intercept (0,-6) leads to b = -6
Both m = -3 and b = -6 plug into y = mx+b to get
y = mx+b
y = -3x+(-6)
y = -3x-6
-----
Now add 3x to both sides
y = -3x-6
y+3x = -3x-6+3x
3x+y = -6
-----
Lastly, multiply both sides by -2 so that the "-6" on the right hand side turns into "12" (each answer choice has 12 on the right hand side)
3x+y = -6
-2(3x+y) = -2(-6)
-2(3x)-2(y) = 12
-6x-2y = 12
which is what choice B shows.
Answer: 6.50h+35 must be greater than or equal to 150
Step-by-step explanation:
First you would subtract x from both sides to move all the x's to one side
Then you would add 4 to both side to move all the non x's to one side
Lastly divide by negative 15 to have x by itself
9/-15 =-.6
So x as has root at x=-0.6
Answer:
A) Fill the blanks, Fail, 0.15, Success, 244, 0.61
B) 240 times
Step by-step explanation:
A) Void , 96, 0.24
Fail, 60, it should be 0.15 because 60/400
Success, 400 - 96- 60 or 244 and the relative frequency is 0.61.
B)
There is a total of 1000. If the relative frequency is 0.24, multiply 0.24 by 1000 to get the amount of times YOU would expect to be VOID.
Or in other words , 240 times
By proving it add all up
0.24 x 1000 + 0.76 x 1000 = 1000
