Answer:
You are correct, the answer is D, 24 degrees
Step-by-step explanation:
First we know that a straight line is 180 degrees. We know that part of it is 156 degrees so that must mean that one side of the triangle is equal to 24 degrees (Subtract 180-156). That is one side.

A) y = -4
B)X 3 = 1
C) 2x -4y =1
D) y= X - 2
2.) Find the value of y that makes the equation y= -x + 5 true, when x =-4
A.) -1
B.) 2
C.) 1
D.) 9
3.) Find the value of y that makes the equation y= x + 1/4 true, when x = - 1/4.
A.) -4
B.) 0
C.) 1
D.) 4
Answer:
1) B
2) D
3) B
Step-by-step explanation:
For question 1:
Assuming that option B is [tex]x^3=1[/tex], it is not a linear function.
Linear functions have equations that do not have exponents.
For question 2:
[tex]y=-(-4)+5\\\\y=4+5\\\\\boxed{y=9}[/tex]
The option is D.
For question 3:
[tex]y=x+\frac{1}{4}\\\\ y=-\frac{1}{4}+\frac{1}{4}\\\\ \boxed{y=0}[/tex]
The option is B.

If you were to rotate the point (-5,8) around the origin 270 degrees counterclockwise what would the new coordinates be?
Answer:
5,8
Step-by-step explanation:
A point (-5,8) rotated around the origin 270 degrees counterclockwise will have coordinates (-8, -5).
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
We know when we rotate a point counter-clockwise the coordinates (x, y) becomes (-y, x).
Given, A point (-5,8) around the origin 270 degrees counterclockwise.
∴ The new coordinates of the points will be (-8, -5).

During a science experiment, your teacher does a demonstration. She takes a
small piece of rope, weighs it to find its starting weight, burns it, and then
weighs it again. The final mass of the product is different from the starting
weight of the reactant.
Why is the final mass different? Does this mean that the product has less
mass? Why or why not?
Answer:
less mass
Step-by-step explanation:
The product has less mass because some of its mass got burned. Hope this helps!

Which statement about the linear factors and zeros of a quadratic function is always true? The constants of the linear factors are the opposite of the function's zeros. A function's zeros can be determined by setting each linear factor equal to 0 and solving. If a function's zero is an integer, then the coefficient of the variable in the linear factor must be one. Multiplying the constants of the linear factors gives one of the function's zeros, and adding the constants gives the other zero.
Answer:
A function's zeros can be determined by setting each linear factor equal to 0 and solving.
Step-by-step explanation:
This is because in finding the zero's of a quadratic function, we factorize the quadratic function to obtain its linear factors. Then, each linear factor is then equated to zero to solve for the zeros of the quadratic function.
The solution of the equating to zero of the linear factors give the zeros of the quadratic function.

What is an equation of the line that passes through the point (6,6) and is parallel to the line 3x-2y=4?
Answer:
Fraction: y= 3/2x-3
or
Decimal: y= 1.5x-3
Step-by-step explanation:
Turn 3x-2y=4 into y=mx+b form
Subtract 3x from both sides
-2y=4-3x
Divide -2 from both sides
y= -2+3/2x
y= 3/2x-2
Since the line is parallel, use slope 3/2

Step-by-step explanation:
First, substitute the equation into the quadratic formula.
[tex]x=\frac{b+-\sqrt{(b^{2} )-4(a)(c)} }{2a}[/tex]
x=[tex]\frac{-3+-\sqrt{(3)^2-4(-2)(4)} }{4}[/tex]

Group of answer choices
Answer:
4; Shari ran past her home after 4 minutes.
Step-by-step explanation:
The x-intercept means that at 4 minutes the distance from home in blocks on her run across town over time is zero.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
6x - 3y = 24
x-intercept means y = 0.
So,
6x - 3 x 0 = 24
6x - 0 = 24
6x = 24
x = 4
Now,
The x-intercept means at 4 minutes the distance from home is o.

By the concept of the intersection of sets 4 students play both basketball and tennis
What are sets and subsets?A set is a collection of well-defined objects.
A subset contains all the elements or a few elements of the given set.
The improper subset is when it contains all the elements of the given set and the proper subset is when it doesn't contain all the elements of the given set.
In this example, we search for the group of students who participate in both sports because we are aware that p is the set formed by the students who play basketball and q is the group formed by the students who play tennis. In other words, we seek the point at where the sets p and q intersect.
Each set is represented by a circle in the Venn diagram, and the set produced by the intersection of p and q is represented by the area where the two circles overlap.
This graph demonstrates that there are 4 kids that participate in both basketball and tennis.
