v-10=-9
Solve for v.
Add 10 to each side of the equation:
v-10+10 =-9+10
v= 1
You have to make the denominators (bottom numbers) the same via multiplication, it's best to do it to the first number they meet at. that would be fifteen (15)
5×3=15
3×5=15
you then have to multiply the numerators by the respective numbers.
2×3=6
1×5=5
you then subtract the numerators normally
6-5=1
slap back on the denominator
1/15
there's your answer.
(the number you multiply them by isn't the other denominator, it just happens to be the denominators for this equation)
Answer:
Step-by-step explanation:
we know that
The solution of the inequality is the shaded area below the solid line (the inequality is of the form 
)
The y-intercept of the solid line is (0,2)
The x-intercept of the solid line is (-4,0)
The slope of the solid line is
The equation of the solid line is 
therefore
The linear inequality represented by the graph is
1) we calculte the driver´s unit rate of speed.
s=speed
d=distance
t=time.
s=d/t
45 miles------------------3/4 hour
x----------------------------- 1 hour
x=(45 miles * 1 hour) / (3/4 hour)=60 miles.
speed or rate=60 miles / 1 hour.
2)we calculate the distance traveled at 1.25 hour.
distance=rate * time
distance=(60 miles /1 hour) * 1.25 hour=75 miles.
Answer: the driver would´t go late, because, the distance is 65 miles, and he can travel 75 miles if he drive with that speed .
