Answer:
No, she will have 140 cards in 4 months
Step-by-step explanation:
the equations is:
f(x) = 100 + 10x
now x = 4
f(4) = 100 + 10(4)
f(4) = 100 + 40
f(4) = 140
140 does not = 60
Answer:
A.
Negative reciprocal gives you the perpendicular slope so negative reciprocal of 1/2 is -2.
Then apply point-slope form.
B. The answer is x = 6.
The midpoint of JK is
The line that goes through JK is just a horizontal line 
because the y-coordinate does not change. So its perpendicular bisector is the vertical line that goes through the x-coordinate of the midpoint, that is, 
.
The answer is

A variable is a letter, for example x, y or z, that represents an unspecified number.
6 + x = 12
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12.
Answer:
x=4
Step-by-step explanation:
Let he first piece be x the second be 3x and the very last one be 7x + 2
Add all the pieces together and you ought to get the length of the rope which is 46 ft
So your equation would be
x + 3x + 7x + 2 = 46
11x = 44
x = 44 / 11
x = 4
so the 3 pieces are 4 , 12 and 30ft
