Answer:

Quadratic equation is x²  + x - 12  = 0.

Step-by-step explanation:

Given : The solutions to a certain quadratic equation are x = -4 and x = 3.

To find : Write the equation in standard form below.

Solution : We have given x = -4 and x = 3.

We can write the solution as x +4 = 0

x - 3 = 0.

Both the solution have GCF is 1

Then solution are (x +4)(x -3) = 0.

On distributing x over (x-3) and +4 over (x-3).

x(x-3) +4(x-3) = 0.

x² -3x +4x -12 = 0.

x²  + x - 12  = 0.

Then  quadratic equation is x²  + x - 12  = 0.

Therefore, Quadratic equation is x²  + x - 12  = 0.

Answer:

x^2 + x -12

Step-by-step explanation:

If the solutions are x=-4 and x=3, then it must have factors (x+4)(x-3). Assuming there is no GCF or leading coefficient other than 1, multiply with FOIL to find the standard form.

(x+4)(x-3)\\x^2 + 4x -3x -12\\x^2 + x -12

A friend has a 83% average before the final exam for a course. That score includes everything but the final, which counts for 25
Klio2033 [76]

Answer:

\mathrm{Best\:course\:grade\:possible:\:}87.25\%,\\\mathrm{Minimum\:score\:on\:final\:to\:earn\:at\:least\:a\:75\%\:for\:the\:course:\:}51\%

Step-by-step explanation:

Assuming the maximum score for the final is 100\%, we can multiply each score by its respective course weight and add them together to give a final score. If your friend did receive this maximum score of 100\%, their overall grade for the course would be:

83(1-0.25)+100(0.25)=\fbox{$87.25\%$}.

To find the minimum score they need to earn a 75% for the course, we set up the following equation:

83(1-0.25)+x(0.25)=75, where x is the minimum score she needs.

Solving, we get:

62.25+x(0.25)=75,\\x(0.25)=12.75,\\x=\fbox{$51\%$}.
