Answer:
x = 3, 8
Step-by-step explanation:
Answer:
×=30⁰ :)
Step-by-step explanation:
x⁰+(x+30⁰)= 90⁰
x⁰+x⁰= 90⁰-30⁰=60⁰
2x⁰=60⁰
60⁰÷2=30⁰ => x⁰=30⁰
verification:
30⁰+(30⁰+30⁰)=90⁰

Answer:
B. 2x^2 -5x +2y
Step-by-step explanation:
Substitute the given expressions and collect terms.
g(x) -f(x)
= (2x^2 -3x +6y) -(2x +4y)
= 2x^2 -3x +6y -2x -4y
= 2x^2 -5x +2y . . . . . . . . . . matches choice B
Answer:
y2 = - 92.57x + 1052 ;
11.331 years
Step-by-step explanation:
Given that :
The linear function that models the population of rainbow smelt is y1 = −19.76x + 227, where
x = the years since 1990 and y1 = the number of rainbow smelt.
The linear function that models the population of boater fish is :
Rate of change, slope = - 92.57 ; initial population, intercept = 1052
Representing the equation in the form ;
y = bx + c
b = slope or rate of change ; c = intercept
y2 = - 92.57x + 1052
To express equality :
y1 = y2
- 19.76x + 227 = - 92.57x + 1052
Collect like terms :
-19.76x + 92.57x = 1052 - 227
72.81x = 825
x = 825 / 72.81
x = 11.331 years
Rectangle because it is more than a square. A square is 1,000 and more than a square is a rectangle.
