Answer:
Slide UP 2
Step-by-step explanation:
In the equation,
f(x) = 9|x+1| + 2
There are three transformations of the parent function f(x)=|x| (this is the simplest form of this function, it's a v-shaped graph)
The 9 in front will vertically stretch the graph and make it look like a "skinny" v-shaped graph.
The +1 in close to the x inside the absolute value bars |x+1| will shift (slide) the graph to the left (it's the opposite of what you might think-- 'plus' shifts the graph left and 'minus' shifts the graph right)
The +2 at the end is the transformation you're looking for. It slides the graph as you would expect UP 2 units. If it was a minus it would shift the graph down instead.
Answer:
J=0.15
S=0.05
Step-by-step explanation:
4J+2S=0.70
4J+5S=0.85
Using elimination method
4J+2S=0.70 (1)
4J+5S=0.85 (2)
Subtract (1) from (2)
3S=0.15
Divide both sides by 3
3S/3=0.15/3
S=0.05
Substitute s=0.05 into (1)
4J+2S=0.70
4J+2(0.05)=0.70
4J+0.10=0.70
4J=0.70-0.10
4J=0.60
Divide both sides by 4
4J/4=0.60/4
J=0.15
CHECK:
4J+2S=0.70
4(0.15)+2(0.05)=0.70
0.60+0.10=0.70
0.70=0.70
4J+5S=0.85
4(0.15)+5(0.05)=0.85
0.60+0.25=0.85
0.85=0.85
Answer: 8
Explanation:
The number line of cards goes by 1 and the number line of wool goes by 2.
So if Jillian wants 4 cards then he will have trade 8 wool for it. :)
This is a badly worded problem
