Only the 3rd one is a quadratic equation if we move the 16 to the other side of the equal sign.
To graph a slope, first you should get the equation into y-intercept form (y=mx+b) m is the slope and b is the y-intercept. When graphing, a person would vertically (up or down depending whether or not b is positive or negative). Slope is diagonal in most cases. If slope is positive then the line should move up going left to right, and if it is negative the line should move downward. I always remember slope by thinking to get to the elevator then move up or down. An example would be if the equation is y=2x-1. I would start at y-intercept. In this case it would be (0,-1), then I would move right 1 and up 2 because slope is technically 2/1. The new point would be (1, 1). Keep doing the step with slope until you have enough points to draw a line through the points. I hope I was able to help you.
6-5=1 because six is being taken away from unlike 10-6=4 where 10 is being taken apart
My savings served to bought 10 candies on the store and left 650, or also could have served to buy 60 candies and had left 400. What is the price of the candies m ?
<span>650 + 10m = 60m + 400
</span>To know the price of the candies, we had to get the value of m:
60m - 10m = 650 - 400
50m = 250
m = 250/50
m = 5
so the price of the candies is 5, and the savings is equal to each side of the first equation:
savings = 650 + 10m = 650 + 10(5) = 650 + 50 = 700<span>
</span>savings = <span>60m + 400 = 60(5) + 400 = 300 + 400 = 700
</span>then the savings are 700
