Which statement describes function composition with respect to the commutative property?

Answers
Answer;
m<EAD=29°
m<CAB=119°
Step-by-step explanation:
Angles on a straight line sum up to 180°
This implies that,
61°+90°+EAD=180°
151°+EAD=180°
Subtracting 151° from both sides,we obtain,
EAD=180°-151°
EAD=29°
Angles on a straight line add up to 180°.
this implies that,
CAB+61°=180°
Subtracting 61° from both sides,we obtain
CAB=180°-61°
CAB=119°
Thus,m<EAD=29° and m<CAB=119°
Answer:
29° and 119°
Step-by-step explanation:
Since CF is a straight line, then
90° + ∠ EAD + 61° = 180°, that is
∠ EAD + 151° = 180° ( subtract 151° from both sides )
∠ EAD = 29°
and
∠ CAB + 61° = 180° ( subtract 61° from both sides )
∠ CAB = 119°
On a coordinate plane, a line with a 90-degree angle crosses the x-axis at (negative 4, 0), turns at (negative 1, 3), crosses the y-axis at (0, 2) and the x-axis at (2, 0).
What is the range of the function on the graph?
Answers
Answer:
B
Step-by-step explanation:
The range of the function is {0, 3}.
The range of a function on a graph is the set of all possible output values (y-values) that the function can take. To find the range of the given function, we need to determine the y-values corresponding to the points where the function is defined.
Let's analyze the points provided:
The line crosses the x-axis at (-4, 0). This means the function's y-value is 0 when x = -4.
The line turns at (-1, 3). This point is on the line, so the function's y-value is 3 when x = -1.
The line crosses the y-axis at (0, 2). This means the function's y-value is 2 when x = 0.
The line crosses the x-axis again at (2, 0). This means the function's y-value is 0 when x = 2.
Now, let's consider the intervals between these points:
a) When x < -4 (to the left of -4): The function's y-value is 0, as the line is horizontal at y = 0.
b) When -4 ≤ x < -1: The function's y-value starts at 0 and increases to 3, as the line rises from (−4, 0) to (−1, 3).
c) When -1 ≤ x ≤ 2: The function's y-value remains constant at 3, as the line is horizontal at y = 3 between (−1, 3) and (2, 3).
d) When x > 2 (to the right of 2): The function's y-value decreases from 3 to 0, as the line descends from (2, 3) to (2, 0) and further to the right.
So, the range of the function is {0, 3}.
In mathematical notation, the range is written as:
Range = {y | y = 0 or y = 3}

To solve this equation, you need to combine like terms and then divide by the coefficient of the variable on both sides of the equation.
To start, add 12c and 6c because they are like terms.
12c + 6c = 18c
Then, divide by 18 on both sides of the equation to solve for c.

Equation of a Straight Line
1.1 Solve y-x-1 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-x-1 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 1/1 so this line "cuts" the y axis at y= 1.00000
y-intercept = 1/1 = 1.00000
Calculate the X-Intercept :
When y = 0 the value of x is 1/-1 Our line therefore "cuts" the x axis at x=-1.00000
x-intercept = 1/-1 = -1.00000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.000 and for x=2.000, the value of y is 3.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 3.000 - 1.000 = 2.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 2.000/2.000 = 1.000
Geometric figure: Straight Line
1. Slope = 2.000/2.000 = 1.000
2. x-intercept = 1/-1 = -1.00000
3. y-intercept = 1/1 = 1.00000
The equation of the line that passes through the given points will be y=1.5x-4.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
A linear equation has the form y = mx + b in the slope-intercept format. X and Y are the variables in the equation. The values m and b represent the line's slope (m) and the value of y when x is 0.
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that the line passes through (0,4) and (2,7)
The slope of the line is,
m = (7-4)/(2-0)
m=3/2
m=1.5
The equation of the line passes through the points (0,4) and (2,7) and has a slope of 1.5 will be,
y-4=1.5(x-0)
y-4=1.5x
y=1.5x-4
Thus, the equation of the line that passes through the given points will be y=1.5x-4.

please help out i’m stuck please and thank you
Answers
======================================================
Explanation:
The given equation is y = (-3/4)x - 2. Comparing it to y = mx+b, the slope is m = -3/4
Flip the fraction and the sign to go from -3/4 to 4/3. This is the perpendicular slope. Multiplying the two slopes gets (-3/4)*(4/3) = -1.
Rule: the original slope and perpendicular slope always multiply to -1, assuming neither line is vertical or horizontal.
We'll use the point (x,y) = (3,6) and the perpendicular slope m = 4/3 to find the y intercept b
y = mx+b
6 = (4/3)(3) + b
6 = 4+b
6-4 = b
2 = b
b = 2
The y = mx+b equation becomes y = (4/3)x + 2 which is the slope intercept form of the perpendicular line.

Extra info:
If you want to convert to standard form Ax+By = C, then you could do the following steps
y = (4/3)x + 2
3y = 4x + 6 ... multiply everything by 3 to clear out the fraction
3y - 4x = 6
-4x + 3y = 6
4x - 3y = -6 ... multiplying both sides by -1; this is to make A > 0
