Answer:
x > -4
Step-by-step explanation:
I just looked it up
But I know this is it
Step-by-step explanation:
Select all of the following that are quadratic equations.
x² + 3x - 5 = 0 ✓
x² - x = 3x + 7 ✓
5x - 7 = 0 X
7x² + 14x = 0 ✓
x³ - 3x² + 1 = 0 X
x - 5 = 9x + 7 X
What is quadratic equations?
Quadratic equations is a equation that has a general form like "ax² + bx = c"
For example :
x² + 3x - 5 = 0
x² + 3x = 5
x² → ax²
3x → bx
5 → c
Answer:
The value of a = 8.
The value of b = 2.
Step-by-step explanation:
Given: where, x = -2
Since, the power is even (10), the resultant will be a positive number.
So, we have:
Note that:
Also,
Therefore, we get:
Hence, a = 8; b = 2
Hence, the answer.
9514 1404 393
Answer:
$55,811.91
Step-by-step explanation:
The amount with interest is given by the formula ...
A = P(1 +r)^t
where r is the annual interest rate and t is the number of years.
A = $25000(1.055^15) ≈ $55,811.91
The amount due at the end of 15 years will be $55,811.91.
Sizes = Small, Medium and Large, so they has 3 choices for size.
Crust = Thin or thick for each size, so they have 2 choices for crust.
Topping = Tomato or meatball for each one, so they have 2 choices for toppings.
The answer would be:
