Answer:
3(p+4m) + 8
Step-by-step explanation:
Factor out a 3 for the first two terms, 3(p+4m) and add 8 like usual
To find the x-intercept what you do is you plug in zero for Y:
0=4x-8
Then you would add 8 to the left side and x =2
Answer:
No, this set of ordered pairs does not represent a function.
Explanation:
Functions have one y-value for a given x-value.
Ordered pairs are written (x, y).
In this set, when x=2, it has four y-values (4, 5, 6 and 7), so it cannot be a function.
Answer:
x is 30/7
Step-by-step explanation:
You want to isolate x.
First, solve 5 * 6/7. The answer is 30/7.
Next, divide both sides by 6/7. This will cancel out the 6/7 on the left . For the right, when dividing fractions, you must take the reciprocal of the second fraction and multiply by it. So instead of having 30/7 divided by 6/7, you will have 30/7 * 7/6. The answer is 210/45 which simplifies to 5.
Third, you want to divide both sides by 7/6. Again the 7/6 on the left will be cancelled out. And you must do 5 * 6/7. In order to make the 5 look like a fraction to reduce confusion, you can set it over 1 (thus, you would do 5/1 * 6/7). The answer is 30/7.
You can plug it back into the equation to check.
