Which point is located on the line represented by
the equation y = 5x + 4?
All points in the format: (x, 5x + 4) are in the line.
A few examples are: [tex](-2,-6), (-1,-1), (0,4), (1,9), (2,14)[/tex]
--------------------------
The equation of the line is:
[tex]y = 5x + 4[/tex]
This means that the points located on the line have the following format:
[tex](x, y) = (x, 5x + 4)[/tex]
Among the examples:
[tex](-2, 5(-2) + 4) = (-2,-6)[/tex]
[tex](-1, 5(-1) + 4) = (-1,-1)[/tex]
[tex](0, 5(0) + 4) = (0,4)[/tex]
[tex](1, 5(1) + 4) = (1,9)[/tex]
[tex](2, 5(2) + 4) = (2,14)[/tex]

Stu hiked a trail at an average rate of 3 miles per hour. He ran back on the same trail at an average rate of 5 miles per hour. He traveled for a total of 3 hours. The equation 3t = 5(3 – t) can be used to find the time it took Stu to hike one way. How long did it take Stu to hike the trail one way? hours How long is the trail? miles What is the total distance Stu travelled? miles
Answer:
Time taken to travel at 3 miles = 1.875
Time taken to travel at 5miles = 1.125
Total distance = 11.25
Step-by-step explanation:
D = speed x time
Time = distance/speed
Time at 3 miles per hour and 5 miles per hour
T1 = d/3
T2 = d/5
Total time = 3 hours
T1+t2 = 3 hours
d/3 + d/5 = 3
= d(1/2+1/5) = 3
d(5+3/15) = 3
d(8/15) = 3
We cross multiply
8d = 45
d = 45/8
= 5.625 miles
Total distance = 2d
2x5.625 = 11.25 miles
Since d is now known
T1 = 5.625/3 = 1.875 hours also 1 hour 52.5 minutes
T2 = 5.625/5 = 1.125 hours = 1 hour 7.5 minutes
Total distance 2xd = 11.25
Answer:
the answer is
A. 1.875 hours
C. 5.625 miles
D. 11.25 miles

help plz
Answer:
x = -9
Step-by-step explanation:
First, subtract 3 from both sides of the equation and distribute the 3 to the x and -2.
3x - 6 - 2x = -15
Now, add the 6 to both sides of the equation and combine 3x and -2x.
x = -9
The value of x is -9.

During a 60-minute period, a traffic engineer counted 54 trucks and cars that crossed a bridge. The ratio of trucks to cars that travel across the bridge is usually 2:7. The equation LaTeX: \frac{2}{7}=\frac{t}{54-t}2 7 = t 54 − t can be used to predict the number of trucks, t, the engineer should have counted. How many trucks should the engineer have counted?
Answer:
Step-by-step explanation:
Given the expression for the equation representing the prediction of number of trucks as;
2/7 = t/54-t where t is the number of trucks
To get the number of trucks t, we will have to evaluate the expression and solve for t as shown;
Given 2/7 = t/54-t
Cross multiply
2(54-t) = 7t
Open the parenthesis
2(54)-2t = 7t
108-2t = 7t
7t+2t = 108
9t = 108
Divide both sides by 9
9t/9 = 108/9
t = 21
Hence the engineers should have counted 21trucks
