She had 22 marbles and gave away, 4 to two people, so 4*2 = 8. 22-8=14. she has 14 marbles left.

Answer:
13x-27
Step-by-step explanation:
Simplify the expression.
1) Parallel lines have equal slopes.
We need to find the slope of the given line by solving for y.
5x - 15y = 30
-15y = -5x + 30
y = (1/3)x - 2
The slope of the given line is 1/3, so the slope of the parallel line is also 1/3.
2) Line 1 has slope 2/3.
Line 2 has slope 2/3.
3) Line 1 is a vertical line through x = 2. Line 2 is a horizontal line through y = -5. The lines are perpendicular.
4) The given line can is solved for y, so we can see its slope is -5/2. The slopes of perpendicular lines are negative reciprocals. The perpendicular line has slope 2/5. We have point (5, 0) which is (x1, y1) in the slope-point formula.
y - 0 = (2/5)(x - 5)
y = 2/5 x - 2
5) The given equation has slope -3. To find the negative reciprocal, write the slope as a fraction, flip it, and change the sign.
Slope of perpendicular line is 1/3.
Answer:
Describes f(x) = |x|, the graph opens up, the range is greater than 0, vertex is at 0,0, the domain is greater than 0
does not describe f(x) = |x|, is symmetric to the x axis, and is increasing over (0, arrow)
Step-by-step explanation:
punch the equation into desmos, I didn't cuz I know that the equation looks like, but you can visualize with any graphing calculator
