Answer:
y = -8x + 3
Step-by-step explanation:
plug in the point and the slope into the slope intercept formula (y=mx+b)
the slope will be the same since you want the line to be parallel
11 = -8(-1) +b now solve for b
11 = 8 + b
-8 -8
3 = b
now write the equation with only the slope and the y intercept
y = -8x + 3
The equation of a line that passes through (-1, 11) and is parallel to the line y = - 8x + c is y = - 8x + 3.
What is the slope intercept form of a line?The slope intercept form of a line is given by -
y = mx + c
m is the slope of line
c is the y - intercept
Given is a line that passes through (-1, 11) and is parallel to the line -
y = − 8x − 2.
Since, the line is parallel to the line → y = − 8x − 2, therefore, their slope will be same and is equal to m = - 8.
Now, in the slope intercept form, assume that the equation of line looks like -
y = - 8x + c
Now, the line passes through the point (-1, 11), we can write -
11 = -8 x -1 + c
11 - 8 = c
c = 3
Hence, we can write the equation of the line as -
y = - 8x + 3
Therefore, the equation of a line that passes through (-1, 11) and is parallel to the line y = - 8x + c is y = - 8x + 3.

Answer:
B) 0.57
Step-by-step explanation:
It says "given that you are in Sacramento", so hint: only look at the Sacramento row. Ignore everything else, you don't need it.
Then it asks what is the probability of a clear day, so you look at the "Clear" column from the Sacramento row. That would be 17 days.
Lastly, you just simply divide from the total days. 17/30 = 0.57

Which functions are symmetric about the y-axis? Check all of the boxes that apply.
The functions that are symmetric about the y-axis are;
1) The function in the first option; f(θ) = cos(θ)
2) The function in the third option; f(x) = x²
Reason for the above selection;
Definition;
A function is symmetric about the y-axis is also known to be an even function such that the same value of the function is arrived at when x is replaced with -x
Analysis of the graphs;
First Function Graph; The graph represents the graph of cos (θ)
∴ The function is f(θ) = cos(θ)
The value of the function when x = π, f(π) = -1
Similarly, the value of the when x = -π, f(-π) = -1
f(π) = f(-π)
∴ f(x) = f(-x)
Therefore; the first function is an even function
Second Function Graph; The function of the graph is x = y²
∴ y = √(x)
The value of the function when x = 4, y = f(4) = 2
However, the when x = -4, f(-4) does not exist
f(4) ≠ f(-4)
∴ f(x) ≠ f(-x)
Therefore; the second function is not an even function (the function, x = y², is however symmetric about the x-axis)
Third Function Graph; The function the graph represents is y = x²
The value of the function when x = 2, f(2) = 4
Similarly, the value of the when x = -2, f(-2) = 4
f(2) = f(-2)
∴ f(x) = f(-x)
Therefore; the third function is an even function
From the above, the functions which are symmetric about the y-axis, (even functions) are;
The first and the third functions

Consider the function f(x) = (x+ 1)2 - 1. Which of the following functions stretches
fo) vertically by a factor of 4?
O A) f0 - (/ax+ 1)2 +3
O B) f9 = 1/ax+ 1)2 -4
Oo fo-4(x+ 1)2 - 1
OD) fo = 4(4x+ 1)2- 1
Answer:
C
Step-by-step explanation:
A coefficient of 4 would have to be added in front of (x+1)^2 in order to vertically stretch the function by a factor of 4.
The answer that demonstrates this is choice C: [tex]f(x) = 4(x+1)^2-1[/tex]
The functions stretches vertically by a factor of 4 will be f(x) = 4(x+ 1)² - 1. Then the correct option is C.
What is the equation of the parabola?Let the point (h, k) is the vertex of the parabola and a is the leading coefficient.
Then the equation of the parabola will be given as,
y = a(x - h)² + k
The quadratic function is given below.
f(x) = a(x+ 1)² - 1
If the value of the leading coefficient lies between 0 to 1. Then the parabola is stretched horizontally.
And if the value of the leading coefficient is greater than one. Then the parabola is stretched vertically.
The functions stretches vertically by a factor of 4. Then the value of the leading coefficient is 4. Then the equation will be
f(x) = 4(x+ 1)² - 1
Then the correct option is C.
