Given: 
Find: 
Solution: We need to plug in the value -2 into every variable x that we have in the expression and simplify to get the solution.
<u>Plug in the values</u>
<u>Simplify</u>
- <u />
Therefore, the ordered pair that would match would have a x-coordinate of -2 and a y-coordinate of 4 producing (-2, 4) which matches option A.
Answer:
Step-by-step explanation:
3+1/2x=0
1/2x=-3
2(1/2)x=(-3)2
x=|-6|
x=6 km
Answer:
A and C.
Step-by-step explanation:
A. 4/18 = 6/27 2/9 = 2/9 (Correct)
B. 4/6 = 16/36 2/3 = 4/9 (Unequal)
C. 3/4 = 9/12 3/4 = 3/4 (Correct)
D. 5/9 = 8/12 5/9 = 2/3 (Unequal)
Answer:
y = -2.5x + 4
Step-by-step explanation:
Slope intercept form: y = mx + b
Isolate the variable y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 5x from both sides.
5x (-5x) + 2y = 8 (-5x)
2y = 8 - 5x
Next, divide 2 from both sides to isolate the y.
(2y)/2 = (8 - 5x)/2
y = (-5/2)x + (8/2)
y = -2.5x + 4
y = -2.5x + 4 is your answer.

Answer:</h3>
D)
<h3>
Step-by-step explanation:</h3>
Given equation:
To simplify this equation, we need to isolate the variables on one side of the equation and the constants on the other side of the equation. To do this, we can <u>simplify the R.H.S</u> as like terms can subtract.
⇒ 
⇒ 
⇒ 
⇒ 
Since both sides of the equation are the same, this system of equations has infinite solutions.
<h3 /><h3>Check:</h3>
We can check our answer by substituting the value of "s" into the equation. As a result, you will see that many values of "s" are satisfying the equation. Thus, Option D is correct.
