Hello there! Here are your answers:
Does Kerri's dot plot match the data in the tally table? No.
<em>Look at any of the hours on the chart vs dot plot. Let's take 4 for example. In the tally table, there are 6 class mates. In the plot, there are 3. So no, it is not the same.</em>
The answers for the other problems are in this order (<em>since it's the number of circles on the dot plot at the given hour</em>):
5 - classmates spent 3 hours at the park
3 - classmates spent 4 hours at the park
6- classmates spent 5 hours at the park
4 - classmates spent 6 hours at the park
I hope this was helpful and let me know if you need more help! :) Have a great day! :)
Plug in y=5x-1 for y in 3x+2y=11
3x+2(5x-1)=11
3x+10x-2=11
13x=13
x=1
plug x=1 to y=5x-1 to find y
y=5(1)-1
y=5-1
y=4
ANSWER: x=1 and y=4 which is (1,4) as an ordered pair
136.8 meter, or 137 meters
Work:
60 minutes x 24 hours =
1,440 minutes in a day
1,440 minutes x 9.5 cm =
13,680 centimeters
13,680 cm = 136.8 meters // 137
Answer:
Pam walks 3/8 of a mile more than Paul
Step-by-step explanation:
1/2 = 4/8
7/8 - 4/8 = 3/8
Answer:
y = - 2x - 13
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x - 5 ← is in slope- intercept form
with slope m = - 2
Parallel lines have equal slopes, thus
y = - 2x + c ← is the partial equation
To find c substitute (- 4, - 5) into the partial equation
- 5 = 8 + c ⇒ c = - 5 - 8 = - 13
y = - 2x - 13 ← equation of parallel line
