If u use the distributive property you get 35a+15-42 and u combine like terms to get 35a-27
Answer:
20x+8
Step-by-step explanation:
Your equation is 0.6g=-7. You are trying to get the value of the variable, G, so you need to isolate it. To do this, you need to get rid of 0.6! Since it is being multiplied by g, you will divide it on both sides to undo the operation. Take 0.6 and say 0.6g/0.6 which will give you g. Now, do the same on the other side of the equal sign and say -7/0.6, which I get -11.666... (-11.6 repeating, or 'bar'-11.6 which you will write as -11.6 with a line drawn over it. If you need it in a fraction, most calculators should have an option to convert it, or you can do it yourself if you know how).
Answer:
there is no price for which weekly revenue would be 1800
Step-by-step explanation:
If there is a solution to the equation ...
r = 1800 = -4p² +40p +1287
then there is a solution to ...
4p² -40p +513 = 0
Comparing this to the standard form quadratic equation
we can match coefficients to see that ...
The discriminant of a quadratic is ...
When we fill in the numbers and evaluate, we find the discriminant is negative. This tells us that solutions to the equation are complex—there are no real solutions, meaning there is no price that will give $1800 weekly revenue.
_____
A graph shows the highest weekly revenue obtainable at any price is $1387, so there is no price that will give revenue of $1800.
