Answer:

Step-by-step explanation:

$\dfrac{1}{2}a\leq12\qquad\text{multiply both sides by 2}\\\\2\!\!\!\!\diagup^1\cdot\dfrac{1}{2\!\!\!\!\diagup_1}a\leq(2)(12)\\\\a\leq24$

Write a quadratic equation with roots of 3/4 and -4

Vaselesa [24]

A quadratic equation given roots is solved by using the relation

${x}^{2} - (sum \: of \: roots)x + product \: of \: roots$

from the question,

sum of the root will be

$\frac{3}{4} + ( - 4) = \frac{3}{4} - 4$

$= \frac{3 - 16}{4}$

$= \frac{ - 13}{4}$

and also, product of the roots will

$\frac{3}{4} \times ( - 4) = - 3$

now substituting the sum of roots and product of roots into the equation

${x}^{2} - ( - \frac{13}{4} )x - 3$

$= {x}^{2} + \frac{13}{4} x - 3$

as the quadratic equation for the root 3/4 and -4

The product of twice a number and six is the same as the difference of eleven times the number and a

Naddik [55]

Answer:

X=-3/8 (x equals negative 3 over 8.)

Step-by-step explanation:

So, you have twice a number and six. That is going to be 2x*6, and that then simplifies into 12x. Now, 11 times the number, would be 11x. The difference between 11x and 3/8 would be 11x-3/8.

So, You now have 12x=11x-3/8.

Combine like factors. So, 12x-11x=-3/8.

Now, you have x=-3/8.

Hope this Helps!! (:
