Answer:
Step-by-step explanation:
4x + 2y = 14
-4x - 2y = -16
0 ≠ -2
no solutions
It would be the third one 7n=10-3n
The answer would be D. (11,14),(8,18)
To find the answer you need to find an equal slope.
To find the slope you need to do y2-y1/x2-x1
Y2 is 18, y1 is 13, x2 is 8, and x1 is 11
18-13/8-11
5/-3=
-5/3
Answer:

Step-by-step explanation:
Given the equation

Note that

and

Combined, 
Solve the equation:

Since
this is the solution to the equation.
Answer:
x=55
a=11.47
Step-by-step explanation:
To find x we add all the angles in the triangle. The three angles in a triangle add to 180 degrees
35+x+90 = 180
Combine like terms
125+x=180
Subtract 125 from each side
125-125+x=180-125
x= 55
To find a
sin 35 = opposite side/ hypotenuse
sin 35 =a/20
Multiply each side by 20
20sin35 =a
11.47152873 =a
