B.x + 42 = 2,402
C.42x = 2,402
D.x - 42 = 2,402
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
By definition, if two lines are parallel then their slopes are equal.
Then, the requested line will have a slope equal to:
Thus, the line is of the form:
We substitute point and find "b":
Finally, the equation is:
Answer:
C) Is there a greater chance of selecting two white marbles in a row or two purple marbles in a row? Plz show your work THANKS!!
Answthat 16 is 42,
Step-by-step explanation:
Understand factoring. ...
Divide by the smallest prime number possible. ...
Rewrite the square root as a multiplication problem. ...
Repeat with one of the remaining numbers. ...
Finish simplifying by "pulling out" an integer. ...
Multiply integers together if there are more than one.
Answer: 33/2
Step-by-step explanation:
3x2+2x-20=2x2+15
6+2x-20=4+15
2x-14=19
2x=19+14
2x=33
x=33/2
The weight of the Alis dog is pounds.
Further explanation:
Consider the weight of the Alis dog as poundsand weight of the cat as pounds.
Since, the weight of the Alis dog is 8 times the weight of the cat. It can be written as follows:
......(1)
Now, the total weight of the cat and dog are given as 54 pounds. It can be written as follows:
......(2)
From equation (1), substitute for in equation (2).
Thus, the weight of the cat is 6 pounds.
Substitute 6 for in equation (1) to obtain the weight of Alis dog as follows:
Thus, the weight of the Alis dog is 48 pounds.
