Answer:
(a) 3x -y = 7
(b) x +3y = 29
Step-by-step explanation:
(a) The standard form of the given line is ...
3x -y = 5
The parallel line will have a constant on the right that makes it go through (5, 8), so it will be ...
3x -y = 3(5) -(8)
3x -y = 7
__
(b) The perpendicular line will have coefficients for x and y swapped and one of them negated. Again, the constant is chosen to make it go through (5, 8).
x + 3y = (5) +3(8)
x + 3y = 29
Put the percent over 100 and reduce.
For example, 75%. Put it over 100: 75/100. Reduce to 3/4.
Answer:
<h2>x = 4</h2>
Step-by-step explanation:
In algebra, the goal is always to isolate the variable, so its value can be determined.
<h3>Step 1: Use distributive property</h3>
-8 = -x + -4
<h3>Step 2: Subtract -4</h3>
-4 = -x
<h3>Step 3: Multiply by -1</h3>
4 = x
<h3>Step 4: Check</h3>
-8 = -(4 + 4)
-8 = -8 ✔
<h3>Step 5: Answer</h3>
x = 4
