You can plug -x - 1 for y in the first equation
2x - (-x - 1) = 10
2x + x + 1 = 10
Combine
3x = 9
Divide
x = 3
Plug 3 for x in any equation ( I'll use th second equation )
y = - (3) - 1
y = - 3 - 1 = -4
x = 3 ; y = -4
(3, -4)
Answer:
Step-by-step explanation:
Since opposite and adjacent is given, we will use tan as trigonometric ratio.
Hence,
opposite = x , adjacent = 14 and 
= 28
So,
tan 28 = x / 14

Answer:
II. Angle C cannot be a right angle.
III. Angle C could be less than 45 degrees.
Answer:
see explanation
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = width × length
let width be w then length is 2w + 3 ( 3 more than twice the width ), then
A = w(2w + 3) ← distribute
= 2w² + 3w
When w = 4 , then
A = 2(4)² + 3(4)
= 2(16) + 12
= 32 + 12
= 44 ft²
