Step-by-step explanation:
PART A
it wpuld be a correlation
PART B Write a function which best fits the data.
So, f(x)=5x+2
PART C
slope and y-intercept of the plot indicates that its going up 5 positive points
The change in Y over the change in X.
The number of units of outputs per number of workers.
Answer:
x ∈ {2π/3, π, 4π/3} ≈ {2.09440, 3.14159, 4.18879}
Step-by-step explanation:
The equation can be put into standard form by adding 1:
2cos²(x) +3cos(x) +1 = 0
(2cos(x) +1)(cos(x) +1) = 0
Values of cos(x) that make this true* are ...
cos(x) = -1/2 . . . . . . . . . true for x=2π/3, x=4π/3
cos(x) = -1 . . . . . . . . . . . true for x=π

Answer:
$11 is her change
Step-by-step explanation:
This is a simple adding and subtracing problem.
What we first do is add up 4+2+3=9 then we subtract 9 from 20 which gives us $11
We can check our answer by add up 11 + 9 to see if it equals to 20
The output is 6, your current selected answer choice.
Answer:
Yes
(-4,-2) is a solution of a given system of equation
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the equation
y = 2 x + 6 ..(i)
Given point (-4,-2)
substitute x =-4 and y = -2 in equation (i)
-2 =2(-4) +6
-2 = -8+6
-2 =-2
∴ The point satisfies the given equation
