Answer:
C
Step-by-step explanation:
ZC is an altitude, thus ∠ZCY = 90°
The sum of the3 angles in a triangle = 180°
Sum the 3 angles in ΔCYZ and equate to 180
90 + 5x + 22 + 12x = 180 ← simplify left side
17x + 112 = 180 ( subtract f112 from both sides )
17x = 68 ( divide both sides by 17)
x = 4
Hence
∠WZC = 12x = 12 × 4 = 48° → C
Answer:
Find the slope of the line. Do that by putting the equation in slope-intercept form, y = mx + b. That means solve for y.
9x+3y = 36
3y= - 9x + 36
y = -3x + 12
The slope, m = -3
------------------
The slope of lines parallel is the same.
The slope of lines perpendicular is the negative inverse, m = +1/3
----------------
Use y = mx + b and the point (1,2) to find b.
2 = (1/3)*1 + b
b = 5/3
The equation is y = (1/3)x + 5/3 (slope-intercept form)
x - 3y = -5 (standard form)

Hi there!
So let's start by establishing what "x" and "y" are going to be in our equation:
x = the number of guests
y = the $8,000 budget
Here's the equation:
8,000 = 25.50x + 350
Now to solve the equation you just have to isolate the "x" :
8,000 = 25.50x + 350
Subtract 350 from each side of the equation
7,650 = 25.50x
Divide each side of the equation by 25.50
300 = x
So your answer is : 300 guests can attend the wedding so that Walt and Traci stay on budget!
Here you go! I really hope this helped, if there's anything just let me know! :)
