<span>P: y + z = 6
Q: 8y + 7z = 1
A. This makes y = -8Y which will eliminate the "y"'s when the equations are added.

Well, the X component (assuming x is the horizontal) is equal to RCosZ
Where Z is the angle and R is the size of the resultant
Substitute into formula :
X component = RcosZ
-3 = Rcos135°
R = -3/cos135°
R = 4.24264...
R = 4.24 (2dp)
The vertical component (or Y component) is equal to RSinZ
Vertical component = RSinZ
= 4.24264... × Sin135°
= 3
The answer is 3

Answer:
y=10.1(x)
x=
Step-by-step explanation:
It is said in the problem that y would represent how much money she earns and x represents the number hours she works.
so it also said that the amount of Jessa earns is proportional to the amount of time she works .
finding y will be easy dividing 252.50 by 25 will give you 10.1
so how did we get that equation
y will represent the amount and x will represent the hours
An isosceles right triangle is composed of a right angle and two congruent acute angles. In this case, 90 + 2x = 180 where x is the acute angle. x is equal to 45 degrees. Using sine law, 8/sin 90 = y / sin 45 where y is the leg of the triangle. the leg's length is equal to 4 sqrt 2.
I’m pretty sure the answer is D
