Answer:
E = $385
Step-by-step explanation:
35 x 11 = 385
Answer:
x = -6
Step-by-step explanation:
y = -x equation 1
x + 6y = 30 equation 2
using equation 1 in equation 2 we have:
x + 6(-x) = 30
x - 6x =30
-5x = 30
x= -30/5
x= -6
Answer:
x = -15 so, 15 ÷ -15 = 0
Step-by-step explanation:
Hope this helps!
Answer:
No
Step-by-step explanation:
To be divisible by 4 the last two digits have to be divisible by 4
so
is 63 divisibly by 4?
no
because is odd and four is even
so we can conclude that 563 is not divisible by 4

Let's say α is the angle that subtends from the top of the screen to horizontal eye-level.
Let β be the angle that subtends from the bottom of the screen to horizontal eye-level.
tanα = (22 + 10 - 4) / x = 28/x
α = arctan(28/x)
tanβ = (10 - 4) / x = 6/x
β = arctan(6/x)
Ɵ = α - β
Ɵ = arctan(28/x) - arctan(6/x)
(b.)
tanƟ = tan(α - β) = (tanα - tanβ) / (1 + tanα tanβ)
tanƟ = (28/x - 6/x) / [1 + (28/x)(6/x)]
tanƟ = (22/x) / [1 + (168/x²)]
tanƟ = 22x / (x² + 168)
Ɵ = arctan[22x / (x² + 168)]</span>
