Answer:
0.75m/s
Step-by-step explanation:
<em>Speed formula: ⇒
</em>
<em>Divide by the numbers from left to right.</em>
<em>S=18</em>
<em>T=24</em>
<em>18/24=0.75</em>
<em>0.75m/s is the correct answer.</em>

Answer:
x = -8
Step-by-step explanation:
y = 3x + 14
2x - 3y = -14
So, what is the substitution? Y of course, this is because y is equal to 3x + 14.
2x - 3 (3x + 14) = -14
Multiply 3 with the numbers in the parentheses.
2x - 9x + 42 = -14
So you maybe be wondering why it is a negative 7 instead of subtracting 9 with 2. Using PEMDAS, we always read from left to right. So it is basically 2 -9 and you get -7.
-7x + 42 = -14
Then subtract 42 from both sides.
-7x + 42 - 42 = -14 - 42
Simplify
-7x = -56
Divide 7 by both sides.
-7x / 7 = -56 / 7
x = -8
And you might ask, why we get x instead afterwards. This is because both -7 and 7 cancel each other out leaving us with x.

Answer:
y = -4x + 8
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Slope Formula: 
Step 1: Find slope <em>m</em>
<em />
<em />
<em />
<em />
m = -4
y = -4x + b
Step 2: Find y-intercept <em>b</em>
4 = -4(1) + b
4 = -4 + b
8 = b
Step 3: Rewrite linear equation
y = -4x + 8
