Answer:
Step-by-step explanation:
sin(Z) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{YZ}{XZ}[/tex]
= [tex]\frac{9}{15}[/tex]
= [tex]\frac{3}{5}[/tex]
cos(Z) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{XY}{XZ}[/tex]
= [tex]\frac{12}{15}[/tex]
= [tex]\frac{4}{5}[/tex]
tan(Z) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{XY}{YZ}[/tex]
= [tex]\frac{9}{12}[/tex]
= [tex]\frac{3}{4}[/tex]
sin(X) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{YZ}{XZ}[/tex]
= [tex]\frac{12}{15}[/tex]
= [tex]\frac{4}{5}[/tex]
cos(X) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{XY}{XZ}[/tex]
= [tex]\frac{9}{15}[/tex]
= [tex]\frac{3}{5}[/tex]
tan(X) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{YZ}{XY}[/tex]
= [tex]\frac{12}{9}[/tex]
= [tex]\frac{4}{3}[/tex]

------ = --------------
15+? 12
15 10
------ = --------------
15+? 12
Using cross products
15 * 12 = 10 ( 15+?)
180 = 10 ( 15+?)
Divide each side by 10
18 = 15+?
Subtract 15 from each side

Solve: 5x=-6x+9
A: x= -9
B: x= -9/11
C: x= 9
D: x= 9/11
Answers
Answer:
x = 9/11
Step-by-step explanation:
5x = -6x + 9
Add 6x to both sides
11x = 9
Divide both sides by 11
x = 9/11
Answer:
X Equals 9/11
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable. So X will equal 9/11, which in decimal form is 0.81.

Describe the graph of the equation y = 0. Is the equation a function?
vertical line; yes
horizontal line; yes
vertical line; no
horizontal line; no
Answers
Explanation: The equation would be considered a function if it was in (y=Mx+b) form. As you showed here we have the (mx) part and not the (b) which would be the slope.
Answer: B. horizontal line; yes
Use the slope-intercept form to find the slope and y-intercept.
Slope:
0
y-intercept:
(0,0)
Yes it is a function. It is a horizontal line.
Every point on this line is of the form (x,4) where x can be any number you want. The y coordinate is fixed at 4 and cannot change. Two points on this line are (0,4) and (1,4). The horizontal line goes through 4 on the vertical y axis.
Why is it a function? Because it is impossible to draw a vertical line through more than one point on the graph of y = 4. The graph passes the vertical line test. Put another way, for any x input, there is exactly one y output.
Side Note: y = 4 is the same as y = 0x+4. Note how its in the form y = mx+b
m = 0 is the slope
b = 4 is the y intercept
Step-by-step explanation: A. vertical line; yes
horizontal line; yes
Yes! Horizontal line represents a function y = f(x)
(1):Firstly, lets understand a function. For a function to be defined, we have a set of independent variables(inputs) (Domain), a set of dependent variables (outputs) (Codomain). And a relation between the variables.
(2): Each input in X must be related to exactly one output in Y. Or else it won't represent a function.. like in the following image.. y is a function of x.Because each element ofX has one& only one image in Y
C. vertical line; no

A line passes through the points (-4,-1) and (4,3). A second line passes through the points (-2,-2) and (2,6). At what point do the two lines intersect
Answers
Answer:
(-2/3 , 2/3)
Step-by-step explanation:
Line 1: (-4,-1) (4,3)
m = (3 - -1) / (4 - -4) = 4/8 = 1/2
equation: (y-3)/(x-4) = 1/2 y-3 = 1/2 x - 2
y = 1/2 x + 1 ....(1)
Line 2: (-2,-2) (2,6)
m = (6 - -2) / (2 - -2) = 8/4 = 2
equation: (y-6)/(x-2) = 2 y-6 = 2x - 4
y = 2x + 2 ...(2)
(2)-(1): 0 = 3/2x + 1
3/2 x = -1 x = - 2/3
y = 1/2 * (-2/3) + 1 = 2/3

therefore
18=10+2x
solve for x
8=2x
x=4
Answer:
The value of x is 4
Step-by-step explanation:
For a given rectangle
Lenght (l) = 2y = 10
Breadth (b) = 10 + 2x = 18
Here,
2y = 10 ...(1)
10 + 2x = 18 ...(2)
Now, For x
10 + 2x = 18
2x = 18 - 10
2x = 8
x = 8/2
x = 4
Thus, The value of x is 4
