Answer:
-3/8
Step-by-step explanation:
This equation is formatted as y=mx+b where m is the slope of the line, x is the x value, and b is the y-intercept. When finding the slope of such an equation, just find what the coefficient of x in the function is. So, this equation is y = -3/8x - 6/5 and m is -3/8, so your slope is -3/8. Hope that helps!

Answer:
D
Step-by-step explanation:
Terrence drove to his sister's house, a distance of d miles. For the first 150 miles, he was able to drive relatively quickly, at 60 miles per hour. For the remaining distance, the road was rougher, and he had to slow his speed by 20 miles per hour. For each part of the journey, he was able to keep a steady speed. The time he spent driving at the faster speed was twice the time he spent driving at the slower speed.
Answer:
The total distance he drove is 350 miles, with an average speed of 46.67 miles/hour.
Step-by-step explanation:
Let [tex]t_1[/tex] and [tex]t_2[/tex] be the time of driving at a slower rate and at a faster rate respectively.
Given that the total distance = d
The speed for the first 150 miles = 60 miles/hour.
So, [tex]150=60\times t_1[/tex] [ as distance = speed x time]
[tex]\Rightarrow t_1=2.5[/tex] hours.
The remaining distance [tex]= d-150[/tex] miles.
Speed for the remaining distance = 60 miles/hour.
As the time he spent driving at the faster speed was twice the time he spent driving at the slower speed,
So, the time of driving at a faster rate, [tex]t_2 = 2t_1=2\times2.5=5[/tex] hours
So, [tex]d-150=60\times t_2[/tex] [ as distance = speed x time]
[tex]\Rightarrow d-150=20\times 5=100[/tex]
[tex]\Rightarrow d = 100+150=350[/tex] miles.
The average speed of the journey = (Total distance)/(Total time taken )
[tex]=d/(t_1+t_2)[/tex]
=350/(2.5+5)
=350/7.5
=46.67 miles/hour.
Hence, the total distance he drove is 350 miles, with an average speed of 46.67 miles/hour.

Joseph type 60 words in 1 and 1/3 minutes what is average typing speed in words per minute
Answer:
45 words per minute
Step-by-step explanation:
60 / 1 [tex]\frac{1}{3}[/tex]
45
The average typing speed of Joseph in words per minute is 45 words per minute.
What is an average speed?The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity.
Now it is given that,
Number of words = typed 60 words
Time taken = 1 and 1/3 minutes
⇒ Time taken = 4/3 minutes
Thus, Average typing speed = Number of words / Time taken
⇒ Average typing speed = 60 / (4/3) words per minute
⇒ Average typing speed = 45 words per minute
Thus, the average typing speed of Joseph in words per minute is 45 words per minute.

The second line where 3 multiplies -m/3=3 times -4
Step-by-step explanation:
Multiplying a negative by a postive will result in negative so multiplying a negative by a negative will result in a postive. Multiplying 3 by -m/3 will result in -m so you should multiply -m/3 by -m so the varuable will be postitive. The answer would be m=12. Hope this helps.
Each day Marisa runs the same distance. She ran 35 miles in the last 5 days. What is the unit rate?
Answer:
7 miles
Step-by-step explanation:
As, we will take unit rate as "x"
So, for one day = x distance
For 5 days = 5(x)
For 5 days she covered 35 miles
So therefore,
5(x) = 35 miles
X= 35/5
X=7 miles
For a day= 7 miles are covered

Answer:
See Below
Step-by-step explanation:
ABCD primes all correspond to x and y values on the graph.
A=
B=
C=
D=
1) y- intercept
2) time of max height
3) time when balloon hits ground
4) x-intercept
5) max height
6) Initial height
So lets look at (0,A)
This would count as the y - intercept as well as the height they started throwing the balloons.
Soo....
A = y-intercept; Initial height
Now, (B,C)
This is the highest point on the graph, therefore it would be the max time and max height.
If we look at this as a person behind the line throwing the ballon, the y would be the height and the x would be the time
B = Time of max height
C=Max height
(D,0)
From the visual above, this point would be where the balloon hits the ground
From the visual in our head, x is time and y is height
Since d is the x, it is the time when the balloon hits the ground. And since
y =0, D is also the x intercept
D = x intercept, Time when balloon hits ground
Therefore,
A = y-intercept; Initial height
B = Time of max height
C=Max height
D = x intercept, Time when balloon hits ground
Hope this helps! =D
