Answer:
Step-by-step explanation:
Quadratic formula: when the equation is
The given equation is . Let's first arrange this so its format looks like :
Subtract 1 from both sides of the equation
Now, we can easily identify 3 as a, -2 as b and 0 as c. Plug these into the quadratic formula:
I hope this helps!
A regular year has 365 days. Every four years, a leap year begins, which has 366 days. If one of the four consecutive years is a leap year and the others are regular years, the expression is
x=3(365) + 366.
x=1095+366
x=1461
There are 1462 days in four consecutive years.
The answer is D. You can rule out A and B by looking at the x value of 0 because the corresponding y value is 7 so you need to add 7 to a number multiplied by 0. And then you know it's not C because if you plug in the 0 for x it doesn't work.

Step-by-step explanation: f(x)= 8x2 + 5=21--> f(x)=21
g(x)= -2x5 - 4=-14--> g(x)=-14
