26. 4 people went to the aquarium
27. $1.50 per game (subtraction property and division property)
This is the order you need to use to solve this problem: PEMDAS
(Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)
So you start with P and make your way down to S
(2x + 3)(x - 6) - 2x² + 3x + 30 First multiply (2x + 3)(x - 6) (distribute)
(2x)x - (2x)6 + (3)x - (3)6 = 2x² - 12x + 3x - 18 = 2x² - 9x - 18
(2x²- 9x - 18) - 2x² + 3x + 30 Simplify by combining like terms
-6x + 12
Answer:
Step-by-step explanation:
to find the slope of a line that passes for two given points we can use this formula (y2-y1)/(x2-x1). x and y inidcate the coordinates of the two points.
A (-2-7)/(-4-5) = (-9)/-9 = 1 (m is positive)
B (-10-3)/(1-1)) = the denominator is equal to zero, so the division is impossibile. This mean that m is undefined and the line is parallel to y axis
<span>(f + g)(x) = 3x² + 2x – 1 and g(x) = 2x – 2
This is the sum of 2 functions f(x) + g(x), that means:
f(x) + g(x) = f(x) + 2x-2 = <span>3x² + 2x – 1
So f(x) = </span>3x² + 2x – 1 - g(x) or f(x) = <span>3x² + 2x – 1 - (2x-2)
f(x) = </span><span>3x² + 2x – 1 - 2x +2
f(x) = </span><span>3x² + 1</span>
