Answer:
13.75 hours
Step-by-step explanation:
First, find how many km the driver can travel:
11(35)
= 385
Then, divide this by 28 to find how many hours the driver can travel:
385/28
= 13.75
So, the driver can travel 13.75 hours
4 red marbles
6 blue marbles
8 green marbles
Add:
4 + 6 = 10
10 + 8 = 18
18 total marbles
Green marbles/total marbles
8/18
Simplify:
8 ÷ 2 = 4
18 ÷ 2 = 9
Simplest form = 4/9
8/18 = 4/9
D. 4/9
Answer:
Step-by-step explanation:
Please enclose the fractional coefficient inside parentheses: y= (1/2x) − 3 for greater clarity.
Make a table of ordered pairs:
x y = (1/2)x - 3
0 -3
1 (1/2)(1) - 3 = -2 1/2
3 (1/2)(3) - 3 = -3/2
The y-intercept is the point at which x = 0, and (from the table) is -3. Plot a dark dot at (0, -3).
Now graph (3, -3/2), leaving a dark dot.
Draw a line thrugh (0, -3) and (3, -3/2).
Answer:

Step-by-step explanation:
Your equation is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. Your line has a slope of 7. In order to find the line perpendicular to this line, we have to take the opposite reciprocal of the slope. The perpendicular slope to m = 7 is m = -1/7. Now we go through x = -5 and y = 6 to find the new equation.
6 = -1/7(-5) + b gives us
6 = 5/7 + b and
b = 37/7
Therefore, the equation of the line perpendicular to your original line is

Divide both sides of this eq'n by -9. You'll get y = -1.
