Answer:
x=4 y=6
Step-by-step explanation:
12 divide by 3 = 4
12 divide by 2 = 6
Answer:
It'd be easist if one of the variables was by itself
Step-by-step explanation:
I.E: y=2x+4 and 2y+x=23
a) see attachment for graph
b) D: [0, 2.5] <em>time cannot be negative so the x-values start at 0</em>
R: [0, 100] <em>height cannot be negative so the y-values start at 0</em>
c) 84 ft <em>refer to the red coordinate on the graph</em>
d) 1.75 seconds <em>refer to the blue coordinate on the graph</em>
e) 2.5 seconds <em>refer to the green coordinate on the graph</em>
<em />
When looking for coordinates at the various given values, remember that x is time and y is height.
- If you are given time, then look at the y-value for height
- If you are given height, then look at the x-value for the time.

Answer:
OK
Let x=the number
2x=double the number
2x+5=the doubled number increased by 5
And we are told that this equals -47
sooooo
2x+5=-47 subtract 5 from each side2x=-47-5=-52
2x=-52
x=-26------the number
CK
2*(-26)=-52
-52 increased by 5=-52+5=-47
-47=-47
