The numerical expression that describes the amount of time it takes Imani to walk to school is x = 5y - 1.
<h3>How do we derive a numerical expression?</h3>
Let:
x = amount of time it takes Imani to walk to school
y = amount of time it takes Imani to ride to school = 3 minutes
The numerical expression that describes the amount of time it takes Imani to walk to school can be written as follows:
x = 5y - 1
Since it takes Imani three minutes to ride her bike to school, we can solve for x by substituting y = 3 as follows:
x = (5 * 3) - 1 = 15 - 1 = 14 minutes

Answer:
y=5/3x+b
Step-by-step explanation:
Supposing CD uses the equation y=mb (meaning CD passes through the origin) and passes through (3,5), we then know the slope if 5/3 and the y intercept is 0. We can then write CD's equation as y=5/3x+0, or just y=5/3x.
So if AB is parallel to CB, then their equation is y=5/3x+b, as we don't the y-intercept yet.
Thank you!
Answer:
x = 2
Step-by-step explanation:
X² = 3x - 7 = 0
X² = 3x = 7
(x + 1) (x + 2) = 7
(x + 1) + x = 7 - 2
x + x = 7 - 3
2x = 4
x = 4/2
x = 2
