(x - 7)² + (y - 3)² = 4 is your equation.
To answer this problem, let p be the price of each scrub. The total bill (t) is the sum of the price of the potting soil (s) and of the 9 scrubs (n). This is depicted in the equation,
$11.50 + 9p = $94.75
The value of p from the equation is 9.25. Thus, each scrub costs $9.25. The answer is letter C.
Answer:
Follow the steps I did in the explanation.
Step-by-step explanation:
It says to evaluate the equation :-
3.2 = 4/5(b - 5)
3.2 = (4/5 × b) + (4/5 × -5)
3.2 = 4/5b - 4
3.2 + 4 = 4/5b
5/4 × 7.2 = b
9 = b
Hope this helps, thank you :) !!
Answer:
A
Step-by-step explanation:
the standard form of a quadratic equation is
ax² + bx + c = 0 : a ≠ 0
obtain (5 + x)(5 - x) = 7 in this form by expanding the factors
25 - x ² = 7 ( subtract 7 from both sides )
18 - x² = 0 ( multiply through by - 1 )
x² - 18 = 0 ← in standard form
with a = 1, b= 0 and c = - 18 → A
