Answer:
$8.40
Step-by-step explanation:
We can write a proportion to find the total amount last year using the information given. A proportion is two equivalent ratios set equal to each other.
We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.
125(y)=100(10.50)
125y=1050
y=8.40
Answer:
is this a question? also, 6/4 is not irrational, it is rational, and an irrational number is a number that cannot be expressed as a ratio of two integers, aka a simple fraction
Answer: x^2+2x+1
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
To find the y- intercept let x = 0 in the function
g(0) = 0 - 0 - 84 = - 84 ← y- intercept
To find the x- intercepts let y = 0, that is
x² - 5x - 84 = 0
To factor the quadratic
Consider the factors of the constant term (- 84) which sum to give the coefficient of the x- term
The factors are - 12 and + 7, since
- 12 × 7 = - 84 and - 12 + 7 = - 5, thus
(x - 12)(x + 7) = 0
Equate each factor to zero and solve for x
x - 12 = 0 ⇒ x = 12
x + 7 = 0 ⇒ x = - 7
x- intercepts are x = - 7 and x = 12
