Answer:
27°
Step-by-step explanation:
XWY and VWY are supplementary
∴ XWY + VWY = 180°
∴ XWY = 180° - VWY
XYW and ZYW are supplementary
∴ XYW + ZYW = 180°
∴ XYW = 180° - ZYW
ΔXWY is a right triangle at X
∴ XWY + XYW = 90°
∴ 180° - VWY + 180° - ZYW = 90°
∴ 180° - 6x + 180° - 4x = 90°
∴ 360° - 10x = 90°
∴ 10x = 270°
∴ x = 27°
1.50x = y that should be a good equation hopefully. If it’s wrong I’m so sorry. Also if I were to find the answer I need more of the context of the question
Answer:
There are two intersections
Step-by-step explanation:
The number of intersections can be found by calculating the delta of the equation
Δ=b²-4ac
if Δ=0, there is 1 intersection
if Δ>0 there are 2 intersections
if Δ=<0, there are no intersections
where the quadratic equation is in the form ax²+bx+c
Δ=7²-4(2)(6)
=1>0
There are two intersections
The radical function is 3√x + 1.
Since the cubic root of zero is zero, 0 would be x.
Add zero and one, which gives you 1. 1 is y.
You get (0,1)
Since this is a positive radical, it would be going to the top right.
So, the domain is x ≥ 0
the range is y ≥ 1
