The diagram shows a triangle.
What is the value of w?
Answer:
The value of w is 63°.
Step-by-step explanation:
All the sides of triangle sum up to 180°.

Took the test
1. Change each of the following equations to the form
y = mx + c. Then, state the values of m and c.
(a) -6x- y = 3
(b) 3x - 4y = 12
(c)-2x + 5y = 10
(d) x + 2y = 4
(e) 8x- 4y = 3
(1) 4x + 5y = -6
Answer:
(a) -6x- y = 3
[tex]6x + y = -3\\ y = -6x -3[/tex]
(b) 3x-4y =12
[tex]3x - 4y = 12\\-4y = -3x +12\\4y = 3x -12\\\\y = \frac{3}{4}x -3[/tex]
(c)-2x + 5y = 10
[tex]-2x + 5y = 10\\5y = 2x + 10\\y = \frac{2}{5}x + 2[/tex]
(d) x + 2y = 4
[tex]x+2y=4\\2y = -x + 4\\y = \frac{-1}{2} x +2[/tex]
(e) 8x- 4y = 3
[tex]8x - 4y =3\\-4y = -8x + 3\\4y = 8x -3\\y = 2x -\frac{3}{4}[/tex]
(f) 4x + 5y = -6
[tex]4x + 5y = -6\\5y = -4x - 6\\y = \frac{-4}{5} x -\frac{6}{5}[/tex]

Which best describes the effect of translating the equation y=1/2x+8 up or down the y axis?
Answer:
Option B, the y-intercept changes
Explanation:
This is because, the y-intercept is located on the y-axis, which is the vertical axis, moving the graph up and down would mean moving it vertically, therefore this would result in the change of the y-intercept.

Which number line model represents the expression 6+(-2)?
Number line model represented in option C represents the expression 6 + (-2).
What is Number Line?Number line is a pictorial representation of numbers, both negative and non-negative numbers, written on a horizontal straight line within specific intervals.
Number line are used to determine basic mathematical operations like addition, subtraction, division and multiplication.
So here, we are adding the value -2 with 6.
First draw an upward arrow from 0 to 6 in order to represent that we are initiating the addition process with 6.
Then the number -2 added to 6 implies that the number 2 is actually deducting from 6.
So we draw a downward arrow to unit units from 6.
Then we get the number 4 corresponding to the point where the arrow ends.
Hence, option C is the model which represents the expression 6 + (-2).

85
Step-by-step explanation:
Answer:
its 85
Step-by-step explanation:
(cosA+sinA)
2
+(sinA−cosA)
2
=2
Answer:
Here we want to solve:
(cos(A) + sin(A))^2 + ( sin(A) - cos(A))^2 = 2
First, remember the two expansions:
(a + b)^2 = a^2 + 2*a*b + b^2
(a - b)^2 = a^2 - 2*a*b - b^2
Using these relations, we can expand:
(cos(A) + sin(A))^2 = cos(A)^2 + 2*cos(A)*sin(A) + sin(A)^2
( sin(A) - cos(A))^2 = sin(A)^2 - 2*sin(A)*cos(A) + cos(A)^2
Replacing that in our equation, we geT:
(cos(A)^2 + 2*cos(A)*sin(A) + sin(A)^2) + (sin(A)^2 - 2*sin(A)*cos(A) + cos(A)^2) = 2
We can simplify this to get:
2*cos(A)^2 + 2*sin(A)^2 + 2*cos(A)*sin(A) - 2*cos(A)*sin(A) = 2
2*cos(A)^2 + 2*sin(A)^2 = 2
We can take the 2 as a common factor to get:
2*cos(A)^2 + 2*sin(A)^2 = 2*( cos(A)^2 + sin(A)^2) = 2
Now we can divide both sides by 2:
2*( cos(A)^2 + sin(A)^2)/2 = 2/2
cos(A)^2 + sin(A)^2 = 1
And this is a trigonometric property that is true for any value of A.
So the equality:
(cos(A) + sin(A))^2 + ( sin(A) - cos(A))^2 = 2
is true for any real value of A.

~AH1807Step-by-step explanation:
2x x(x-1) = x x (x+4)
2x x (x-1) - x x (x+4)= 0
2x^2 - 2x - x x (x+4) = 0
2x^2 - 2x - x^2 - 4x = 0
x^2 - 2x - 4x = 0
x^2 - 6x = 0
x x (x-6) = 0
x = 0
x - 6 = 0
x = 6
The equation has 2 solutions
x1 = 0, x2 = 6
