Answer:

Step-by-step explanation:
The car uses 15 gallons of gasoline to drive 420 miles.
(15 gal)/(420 mi) = 1/28 gal/mi
The car uses 1/28 gallon of gasoline per mile.
y = mx + b
When x = 0, at the start of the drive, the car has 15 gallons of gasoline.
y = mx + 15
Then for every mile it travels, the amount of gasoline goes down by 1/28 gal. For x miles of travel, it uses 1/28 * x gallons of gasoline.

you would multiply 10 x -12 by distributing the 10 into the parenthesis.
The answer would be negative because a postive times a negative is a negative.
The answer is -120
Answer:
<u><em>The answer will vary depending on what table you were given.</em></u>
<u><em></em></u>
Step-by-step explanation:
I'm pretty sure you were given a table along with this question. I do not have this table, so I'm going to create my own. Before I do, I'll explain the function if that's what you're wondering.
Function: y = -3x
This function means you multiply -3 by x to get y.
An example of this is x = 6. To find y, we multiply -3 by 6; y = -18 in this example.
Now, I'll make a small chart with x going from 0 to 5.
| X | Y |
| 0 | 0 |
| 1 | -3 |
| 2 | -6 |
| 3 | -9 |
| 4 | 12 |
| 5 | -15 |

Answer:
No solutions
Step-by-step explanation:
4(x + 3) - 4 = 8x + 10 - 4x
4x + 12 - 4 = 8x + 10 - 4x
4x + 8 = 4x + 10
4x = 4x + 2
0 ≠ 2
Best of Luck!
Answer:
f(6) = 35
Step-by-step explanation:
f(6) means the function value for the x-coordinate 6. To find this, we need to find out which function to use (either 0 or 35x-175). 0≤x≤5 means that f(x)=0 for any value between 0 and 5 and including 0 and 5 themselves. However, we need to find the value for x=6, so we need to use the other function (35x-175). This gives us:
f(6) = 35 * 6 - 175 = 210 - 175 = 35
I hope this helps!
