2x + 3y = 1470
Minus 2x from both sides gives
3y = 1470 - 2x
divide through by 3
y = 490 - 2/3x
Answer:
The answer is - 28 plus 16 and 12 together and u get 28 but bc there is a - beside 12 u put that in beside the 28
Answer:
length of side = 10x + 3
Step-by-step explanation:
The area of a square = s² ( s is the length of the side )
given
A = 100x² + 60x + 9 ← perfect square in the form
(a + b)² = a² + 2ab + b²
100x² = (10x)² ⇒ a = 10x
9 = 3² ⇒ b = 3
and 2ab = 2 × 10x × 3 = 60x, hence
100x² + 60x + 9 = (10x + 3)²
s =
= 10x + 3 ← length of side
Answer:
The expanded form: y=(2x-3)(x+3)
The simplified form: 2x^2+3x-9
Answer:
Step-by-step explanation:
A function f is continuous on its domain D if f is continuous at every point c∈D. Example 1. The function f(x)=ex (with domain R) is continuous on its domain.
