Hi!
For this equation, you can solve it by using the quadratic formula:

Answer:The equivalent expression of the given terms is 13p
Answer:
Option A. f(x) = 2*(0.25)^x
Step-by-step explanation:
As x increases f(x) decreases so the base of the exponential part is < 1.
So it looks like (0.25)^x is included in the function. When x = 0, f(x) = 2.
Now (0.25)^0 = 1 so 2 * (0.25)^0 will make f(x) = 2.
The answer is f(x) = 2*(0.25)^x.
Answer:
x = -3
Step-by-step explanation:
First Subtract the lowest variable which would be "y" from 9y. 9y changes to 8y and y cancels out, bring everything else down. the equation is now 8y-1=-25. Now add positive one to both sides -25 becomes -24 and -1 cancels out. the equation is now 8y=-24. -24 divided by 8 equals -3 and the 8y cancels out. the equation is now x equals -3.
Answer:
B) x scale of -15 to 15
C) y scale of 0 to 15
Step-by-step explanation:
The change in y-value is 1/4 of the change in x-value, and the y-intercept is 8. That means a y-scale of -30 to 30 would not be well-utilized over a small range of x. (It would take an x-range of about 200 to make much use of that y-scale.)
An appropriate y-scale is one that has 8 near its middle. The corresponding x-scale is then roughly ±4 times half the y-scale. The closest choices are ...
-15 ≤ x ≤ 15 . . . . choice B
0 ≤ y ≤ 15 . . . . . . choice C
