The formula for an exponential equation is y = a * b^x with a and b being a fixed value.
"a" would also be the Y intercept, which is where the graph touches or crosses the Y axis. In the given graph, the curved line touches the Y axis at 100, so the value of a would be 100.
Now we need to find b.
The blue dot at Y 50 is lined up with x = 1, so we can use the point (1,50)
Using the X and Y values we can solve for b:
format: y = a * b^x we replace the letters with the numbers above:
50 = 100 * b^1
b^1 = b so now we have:
50 = 100 *b
Divide both sides by 100 to get b by itself:
b = 50/100, which reduces to 1/2, so b = 1/2
So the equation of the graph becomes y = 100(1/2)^x
You may need to write the 1/2 as 0.5, not sure how you need to enter it.
Answer: H=46
Step-by-step explanation:
-18+h=28
you would add 18 to 28 and then that makes 46 you answer
Step-by-step explanation:
total slices :12
mark eats: 5
aisha eats:4
4+5=9
9-12=3
so, james eats 3 slices
3/12
22a is < since multiplying something by a fraction less than one makes it smaller.
22b is = since multiplying something by a fraction equal to one makes it stay the same.
22c is > since multiplying something by a mixed number makes it larger.
22d is < since multiplying something by a fraction less than one makes it smaller.
Hope this helps!
