Answer:
-1
Step-by-step explanation:
Using the slope-intercept form equation, you know that y=mx+b.
m is the slope of the line and b is the y intercept. The y intercept is where the point is when x=0. If you look at your equation and replace x with 0, you'll see that the y intercept (b) is 9.
You're looking for the slope of Line Q which is m in the equation. In this equation the slope is - 1.
Since Line R is supposed to be parallel to Line Q, then they must have the same slope. So both lines have a slope of - 1.
Answer:
The answer is
Step-by-step explanation:
When we divide two fractions, we multiply the numerator by the inverse of the denominator. So
The answer is
Answer:
20 lizards
Step-by-step explanation:
<h2><u>Number of lizards</u></h2>
this stem and leaf diagram shows the key of:
4║1 meaning 41.
look at the top values. there is nothing under 0 and 1. but there is under 2
2 ║0 means 20 lizards.
<h3><u>therefore the smallest number of lizards at any one zoo is 20 lizards</u></h3>
Ideal timeline of the dance routine = 4 minutes = 4 × 60 seconds = 240 seconds
Variation allowed in the dance routine timeline = +- 5 seconds
Let the timeline of the dance routine be T
⇒ 240 seconds - 5 seconds < T < 240 seconds + 5 seconds
⇒ 235 seconds < T < 245 seconds
⇒ minutes < T < minutes
⇒ 3.92 minutes < T < 4.08 minutes
So the least possible time of the dance routine can be 3.92 minutes (or 235 seconds) and the greatest possible time of the dance routine can be 4.08 minutes (or 245 seconds)
