Answer: 8</h2>
Step-by-step explanation:
Therefore, Mel has to work at least 7.5 hours or 8 total hours.
The ans is C because ..
75/100 x 150 = 112.5
Time = t = ?
Distance 1 = d1 = 224 miles
Distance 2 = d2 = 175 miles
speed1 = v1 = d1/t
speed2 = v2 = d2/t
Also, speed 1 = 14 + v2 (Given in the data)
OR speed 1 = 14 + d2/t
speed 1 = 14 + 175/t
224/t = 14 + 175/t
multiplying both sides (each term) by "t" we get
224 = 14t +175
OR 14t = 49
t = 3.5 hours
now, speed of 1st car = 224 miles / 3.5 hours
= 64 miles / hour
and speed of 2nd car = 175 miles / 3.5 hours
= 50 miles/ hour
The slope intercept form is 
.
Solution:
Given data: slope = 
and y-intercept = –1
y-intercept means (x, y) = (0, –1)
Equation of a line for slope intercept form: 
Here, 
and 
.
⇒ 
⇒ 
Do cross multiplication.
⇒ 
⇒ 
⇒ 
Divide both sides of the equation by 4.
⇒ 
⇒
Hence the slope intercept form is .
