HELP Solve for w x and y
Step-by-step explanation:
take ∆PRT
angle prt = 30°(||sides, traversal, opp angles)
angle ptr = 45+y(|| sides, opp angles)
x+30+45+y = 180
x+y = 180-75= 105
x= 105-y
take triangle zrt
angle zrt =30(parallel sides and traversal with opp angles)
angle ztr = y(parallel lines)
30+y+w = 180
w = 150-y
angle pzt+azr = 360-300+2y=60+2y
pzt= 30+y
triangle pza
30+y + 45+30= 180
y = 180-105=75
w = 75
x=30

A photograph measures 10 inches wide by 18 inches long. The picture is reduced so that the length is 6 inches, what is the new width?
Answer:
19
Step-by-step explanation:
Answer:
The width would be 3 1/3 inches or 3.333 repeating
Step-by-step explanation:
Since you divide the length by 3, you would also have to divide the width by 3. 10 divided by 3 is 3 1/3 or 3.333 repeating (whichever one you choose).

I NEED HELP ASAP!!!!
Answer:
(a) 1
(b) 1 3/4
(c) [-2, 4]
(d) [-1/4, 2]
Step-by-step explanation:
Apparently, the vertex of the graph is (1, 2) and it goes through points (-1, 1) and (3, 1). In vertex form, the equation for this is ...
y = a(x -1)^2 +2
We can find the value of 'a' from the point (3, 1):
1 = a(3 -1)^2 +2 = 4a +2 . . . . substitute for x and y, and simplify
-1 = 4a . . . . . . . subtract 2
-1/4 = a . . . . . . divide by 4
So, ...
f(x) = -1/4(x -1)^2 +2
__
(a)Above, we assumed point (-1, 1) was on the graph:
f(-1) = 1
__
(b)Using the equation we found, ...
f(2) = -1/4(2 -1)^2 +2 = -1/4 +2
f(2) = 1 3/4
__
(c)The domain is the horizontal extent of the graph, apparently from x = -2 to x = 4.
domain: [-2, 4] or -2 ≤ x ≤ 4
__
(d)The range is the vertical extent of the graph. The minimum can be found at the end of the domain:
f(4) = -1/4(4 -1)^2 +2 = -9/4 +2 = -1/4
The maximum has already been established as the vertex at y=2.
range: [-1/4, 2] or -1/4 ≤ y ≤ 2

The points for a linear function are (0, -2), (1, 1) and (2, 4)
Linear equation
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Given that the relationship between f(x) and x is given by:
f(x) = 3x - 2
When x = 0: f(0) = 3(0) - 2 = -2
When x = 1: f(1) = 3(1) - 2 = 1
When x = 2: f(2) = 3(2) - 2 = 4
The points for a linear function are (0, -2), (1, 1) and (2, 4)

What is the sum of the measures of the interior angles of a 20-sided figure?.
Answer:
3240°
Step-by-step explanation:
The equation to find the sum of the measures of the interior angles of a figure is:
(n-2)*180
Where n represents the amount of sides the figure has. In this case the figure has 20 sides so its interior angles sum up to:
(20-2)*180=18*180=3240°

[tex]6 \times 27 \times 28 \times 23 \times 3 = 312984[/tex]
Answer:
312984
Step-by-step explanation:
To solve the equation 6 x 27 x 28 x 23 x 3, you can follow these steps:
Start by multiplying the first two numbers: 6 x 27 = 162.
Then multiply the result by the next number: 162 x 28 = 4536.
Continue multiplying by the next number: 4536 x 23 = 104328.
Finally, multiply by the last number: 104328 x 3 = 312984.
The final result is 312984

What is the solution to the system of equations? (Hint: Use Substitution.)
2 lines Line 1: y equals negative 3 x plus 6 Line 2: y equals 9
Answer:
(-1,9)
Step-by-step explanation:
y = -3x + 6
y = 9
-3x + 6 = 9
-3x = 3
x = -1
y is already given as 9, but you can solve for y by plugging the x value into y = -3x + 6,
-3(-1) + 6 = 9
(-1,9)
Solve the system
of equation by
using subsitution,
Y=2x +3
x - y = -2
Answer:
The solution to this system of equations is (-1, 1).
Step-by-step explanation:
A system of equations is a "a finite set of equations for which common solutions are sought". Or, they are a pair (or more) of equations that either intersect, are parallel, or the same line. For the sake of simplicity, we are going to focus on systems of equations that intersect and only have one solution.
A solution to a system of equations that intersect is represented by a point (x, y). This makes sense because at the intersection of two points, there lies a point.
So how do we find this point? We do this by solving the system of equations. We show that there exists a point in which two lines can be satisfied simultaneously. But how can we do that? Trial and error?! Well, no. There are some ways of approaching this.
The first method is graphing. By either using an external source or doing it yourself, graphing two lines and showing where they intersect is one of the more understandable ways of solving a system of equations. The point where they cross is the solution of the system.
The second method is elimination. This is observing that a system of equations can be combined together to eliminate a variable (x or y) and solving for the other in a one-variable equation. For example, say that I have this system of equations:
x - y = 1
x + y = 1
By simply adding the two together, I get:
2x = 2
x = 1.
Since we already have x = 1, we can substitute it back into one of the original equations to get y.
1 + y = 1
y = 0.
So, the solution to this system of equations would be (1, 0). Speaking of substituting ...
The third method is substitution. This is observing that a variable (x or y) can be written in terms of the other and then using that to substitute in and make one of the equations one-variable.
y = 2x + 3
x - y = -2
We can see that y is already in terms of x in the first equation, so let's substitute y for 2x + 3 in the second equation.
x - (2x + 3) = -2
- x - 3 = -2
- x = 1
x = -1
We can substitute x back into one of the original equations.
y = 2(-1) + 3
y = -2 + 3
y = 1
Therefore, the solution to this system of equations is (-1, 1).

Two poles meet at the top of the teepee. The angle at which they meet is equal to twice the complement of the angles that the poles form with the ground. What is the measure of the angle at which the two poles meet at the top of the teepee
The measure of the angle at which the poles meet at the top of the tepee is 180 degrees
Complementary anglesComplementary angles are angles which sum is equals to 90 degrees. Two angles complement each other when there sum is 90 degrees.
The two poles meet at the top of the tepee.
The angle at which they meet is equals to twice the complement of the angles that the poles form with the ground. Therefore,
Complement of the angles that the poles form on the ground = 90°
Then the measure of the angle at which the poles meet at the top of the tepee is as follows:
2(90) = 180°Therefore, the measure of the angle at which the poles meet at the top of the tepee is 180 degrees
