Answer: A perfect square is a positive integer that is obtained by multiplying an integer by itself.
They are 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400, 441, 484, 529, 576, 625, 676, 729, 784, 841, 900 and 961
-13 because rate of change is basically slope
y = 7 - 13x converts to y = -13x + 7 which is slope - intercept form
the slope is "married" to the x in slope - intercept form

<u>Complete Question:</u>
<em>Ben is 4 times as old as Ishaan. 6 years ago, Ben was 6 times as old as Ishaan. How old is Ishaan now?</em>
<em />
Let Ben's age be "b" and Ishaan's age be "i"
Since Ben is 4 times as Ishaan, we can write:
b = 4i
Ben was 6 times as Ishaan, BUT 6 years ago, we setup the equation like shown below:
b - 6 = 6(i - 6)
Multiplying, we have:
![b - 6 = 6(i - 6)\\b-6=6i-36](https://tex.z-dn.net/?f=b%20-%206%20%3D%206%28i%20-%206%29%5C%5Cb-6%3D6i-36)
Now, we replace b with "4i" and solve for i (Ishaan's age now):
![b-6=6i-36\\4i-6=6i-36\\2i=30\\i=\frac{30}{2}\\i=15](https://tex.z-dn.net/?f=b-6%3D6i-36%5C%5C4i-6%3D6i-36%5C%5C2i%3D30%5C%5Ci%3D%5Cfrac%7B30%7D%7B2%7D%5C%5Ci%3D15)
Ishaan is now 15 years old
Answer:
99% of 900 = 891
Step-by-step explanation:
Answer:
b (0, 4)
Step-by-step explanation:
The other options already have an input (the x) in the function so it must be b.
Las otras opciones ya tienen una entrada (la x) en la función, por lo que debe ser b.
