Answer:
multiplied 4
9 the same
Step-by-step explanation:
Tina multiplied 4 by 4 to get 16, and 9 by 9 to get 81. she should have multiplied each term by the same number.
The midpoint bisects PR, making it 2 equal halves.
Let x be the number of refrigerators
Y be the number of pianos
So the inequality:
300x + 475y < 7100
So substitute 12 and 8 to the inequality
300(12) + 475(8) < 7100
3600 + 3800 < 7100
7400 < 7100 is not true
So it will overload the truck
Recall that an equation in slope-intercept form is as follows:
![y=mx+b,](https://tex.z-dn.net/?f=y%3Dmx%2Bb%2C)
where m is the slope of the line, and (0,b) is the y-intercept.
Substituting m=-6, and b=-1/2 we get:
![y=-6x+(-\frac{1}{2})\text{.}](https://tex.z-dn.net/?f=y%3D-6x%2B%28-%5Cfrac%7B1%7D%7B2%7D%29%5Ctext%7B.%7D)
Simplifying the above result we get:
![y=-6x-\frac{1}{2}\text{.}](https://tex.z-dn.net/?f=y%3D-6x-%5Cfrac%7B1%7D%7B2%7D%5Ctext%7B.%7D)
