When you plug the equation into a graphing calculator the x-intercept is -5
Or you can set the equation equal to 0 and solve for x.
Answer:
A) y = -1/2x + 1/2
Step-by-step explanation:
Find the y-intercept(when x = 0), which is 1/2.
Find the slope: m = y2-y1 / x2-x1
I used points: (3, -1), (-3,2)
m = 2 - (-1) / -3 - 3
m = 3 / - 6
m = -1/2
plug this into the slope intercept form equation: y = mx + b
y = -1/2x + 1/2
Answer:
precisely 8 pounds and 3125 ounces
Step-by-step explanation:
Answer:
c=13 Perimeter=30
Step-by-step explanation:
c is equal to 13 so add all the sides together and you get 30
To know the initial amount of the radioactive substance, you should read the graph in the y - axis when the x = 0, because at x = 0 this means the intial point of the graph or the initial amount of the substance. so at x = 0 the y = 45 so the initial amount is 45 g
