Answer:
Nw how old is the girl, her mum & her dad?
let x=xmum's age
x+5=dad's age
x/2 =girl's age
x+x+5+x/2=100
3.5x=95
xmum's age=38
dad's age=43
girl's age=19
The answer is 64 boys are in the soccer league.
X/160 = 40/100
X/160 * 100 = 40/100 * 100
5x/8 = 40
(8 * 5x)/8 = 40 * 8
5x = 320
5x/5 = 320/5
x = 64
Answer: Ix+10I
Step-by-step explanation: To shift the graph 10 units to the left, we replace x with x+10. What's really going on is that the xy axis shifts 10 units to the right (because x is now x+10; eg, x = 2 ---> x+10 = 2+10 = 12) so it appears that the graph is moving to the left. The general rule is h(x) = g(x+10).
So,
g(x) = |x|
g(x+10) = |x+10| ... every x has been replaced with x+10
h(x) = g(x+10)
h(x) = |x+10|
We can use a graphing tool like GeoGebra to visually confirm we have the right answer (see attached). Note how a point like (0,0) on the green graph moves to (-10,0) on the red graph.
