Answer:
Supplementary Angles add up to 180°
Step-by-step explanation:
(2x + 5) + (8x - 25) = 180
10x -20 = 180
10x = 200
x = 20
Use the formula (b/2)^2 in order to create a new term. Solve for x by using this term to complete the square.
x = 1 ±
Answer:
x = 4, y = 1 is the solution of the given system of equation.
Step-by-step explanation:
Here, the given set of equations is:
3 x + 2 y = 14
x + y = 5 ⇒ y = 5- x
Solve the given system by SUBSTITUTION METHOD:
Substitute the value of y = 5- x in 3 x + 2 y = 14 , we get
3 x + 2 y = 14 ⇒ 3x + 2 (5- x) = 14
or 3 x - 2x + 10 = 14
⇒ x = 10+ 14 = 14 - 10
or, x = 4
Now, y = 5 - x = 5- 4 = 1
Hence, x = 4, y = 1 is the solution of the given system of equation.
Answer:
Explanation:
The first pic shows the line graphed, while the second pic shows how to turn the equation into proper slope-intercept form.
The only steps the second pic is missing however, is flipping the sides around to be better understood (optional), and more importantly subtracting 2 on both sides in order to move it to the other side, to get 2y = x - 2. And dividing the 2 on both sides to get y by its self, to get:
y = (x-2)/2 , or y = 1/2 x - 2/2 , which if you notice 2/2 makes it equal to one whole so your answer is y = 1/2 x - 1 .
