two buses leave towns 604 mi apart at the same time and travel toward eachother. One bus travels 9 mi/h faster than the other on
muminat

Answer:

s = 71 mph, and s+9 = f = 80 mph

Step-by-step explanation:

The distances the two busses travel add up to 604 mi.

Letting f be the faster speed and s the slower.  Then f = s + 9 (mph).

Then (s + 9)(mph)(4 hr) + (s)(mph)(4 hr) = 604 mi.  Solve this for s:

4s + 36 + 4s = 604 mi, or 8s = 568.  Finally, s = 71 mph, and s+9 = f = 80 mph.

Write an equation of the line that has a slope of 6 and contains the point (1,1) in point-slope form.
BigorU [14]
Point-slope for a line is:

(y-y1)=m(x-x1) where (x1,y1)=(1,1) and m=6 so

y-1=6(x-1)

What’s the vertical and horizontal line?
coldgirl [10]

Answer:

Part 1) Vertical line : x=1

Part 2) Horizontal line :  y=-4

Step-by-step explanation:

Part 1) Write the equation for the vertical line passing through the point (1,-4)

we know that

The equation of a vertical line (parallel to the y-axis) is equal to the x-coordinate of the point that passes through it

so

The x-coordinate is 1

therefore

The equation of the line is

x=1

Part 2) Write the equation for the horizontal line passing through the point (1,-4)

we know that

The equation of a horizontal line (parallel to the x-axis) is equal to the y-coordinate of the point that passes through it

so

The y-coordinate is -4

therefore

The equation of the line is

y=-4

How do I substract 7/10 minus 3/15
Bond [772]

Answer: 0.5

Step-by-step explanation:

To reduce a fraction: divide the numerator and denominator by their greatest common factor, GCF.

Fraction: 7/10 already reduced to the lowest terms.

The numerator and denominator have no common prime factors.

Their prime factorization:

7 is a prime number;

10 = 2 × 5;

gcf (7; 2 × 5) = 1;
