The scatter plot below represents the change in global sea level from 1993-2017, according to the National Aeronautics and Space Administration (NASA) The equation of the regression line is written below, where Y represents the predicted change in sea level and t represents the years since 1993.
y = 0 + 3.2t
Part a:
Identify the y-intercept of the regression line and explain what it represents in the context of the data.
Answers
Answer:
The y-intercept is zero and it means that in the year 1993 there was no change in the seawater level.
Step-by-step explanation:
See the scatter plot graph attached.
It represents the change in global sea level from 1993-2017, according to the National Aeronautics and Space Administration (NASA).
The equation of the regression line is written below, where Y represents the predicted change in sea level in mm and t represents the years since 1993.
y = 0 + 3.2t .............. (1)
Therefore, the equation is in the slope-intercept form and the y-intercept is zero for this graph.
That means in the year 1993 there was no change in the seawater level. (Answer)

$375* (25/100)= $93.75.
The cost of the television after sale off and before the sales tax is:
$375- $93.75= $281.25
The sales tax is:
$281.25* (6.5/100)= $18.28
The price of the television including everything is:
$281.25+ $18.28= $299.53

5x - 2y = 32
Answers
The solution is x = 2 and y = -11
Solution:
Given system of equations are:
x + y = -9 --------- eqn 1
5x - 2y = 32 ------------- eqn 2
We have to solve the system of equations
We can solve the system by substitution method
From eqn 1,
x + y = -9
Isolate "y" to one side
y = -9 - x ---------- eqn 3
Substitute eqn 3 in eqn 2
5x -2(-9 - x) = 32
5x + 18 + 2x = 32
Combine the like terms
7x = 32 - 18
7x = 14
x = 2
Substitute x = 2 in eqn 3
y = - 9 - 2
y = -11
Thus the solution is x = 2 and y = -11

A function assigns the value of each element of one set to the other specific element of another set. The correct option is C.
What is a Function?
A function assigns the value of each element of one set to the other specific element of another set.
The x-intercepts of the function f(x) = x² + 4x + 3 can be found as shown below.
f(x) = x² + 4x + 3
0 = x² + 4x + 3
0 = (x+3)(x+1)
x = -3, -1
Now, it can be seen that Mathieu has actually set the factored expressions equal to each other, which was wrong.
Hence, the correct option is C.

Answer:
I can't see Mathieu's work but I will show the right steps and maybe you can find where Mathieu went wrong.
f(x)=x^2+4x+3
f(x)=(x+3)(x+1) Since 3*1=3 and 3+1=4
The x-intercepts can be found by setting y to 0 and solving for x
(in other words replace that f(x) thing with 0 and solve for x)
0=(x+3)(x+1)
Now set both factors equal to 0
x+3=0 or x+1=0
x =-3 x=-1
The x-intercepts are at (-3,0) and (-1,0)
