What is 2a^2-14=-24 factored

1 answer:

3 0

The answer: "(a − 4)(a − 3) = 0" ;
______________________________________
→ {assuming the question meant to be written as:
"What is: 2a² − 14x= -24 ; factored?" } ;
______________________________________
Explanation:
______________________________________
Given: " 2a² − 14x= -24 "; factor this equation ;
______________________________________
Simplify the equation by dividing the entire equation (each side) by "2" ;
______________________________________
 { 2a² − 14x = -24 } / 2 =

a² − 7 = -12

Now, add "12" to each side of the equation:
____________________________________
 a² − 7x + 12 = -12 + 12 ;

to get:
 a² − 7 + 12 = 0 ;
__________________________________
Now, what factors of "12"; when added together, equal "-7"?

6, 2 = 8
-6 -2 = -2,
12, 1 = 13,
-12 -1 = 12
4, 3 = 7,
-4 -3 = -7 .
________________________________________
So; "a² − 7x + 12 = 0" ; factors to:
________________________________________
"(a − 4)(a − 3) = 0 " .
________________________________________
{The solutions are: a = 4 ; and: a = 3} .

Answer:

Follows are the answer to the given point.

Step-by-step explanation:

In point 1:

$\to P( \text{number of response}) = \frac{192}{338} \\$

$= \frac{96}{169}\\\\= 0.56$

In point 2:

$\to P| \text{(Zoloft and fill response)}| = \frac{27}{338}$

$= 0.079$

In point 3:

$\to P(\frac{\text{ full or partial}}{\text{St. John's Wort}}) = \frac{\frac{43}{338}}{\frac{113}{338}}$

$= \frac{43}{338} \times \frac{338} {113}\\\\= \frac{43}{113}\\\\= 0.38$

In point 4:

$\to P(\frac{\text{Placebo}}{\text{full or response}}) = P(\frac{(\text{Placebo} \cap \text{full or response})} {\text{p(full response)}})$

$= \frac{\frac{79}{338}}{ 1- \frac{91}{338}} \\\\ = \frac{\frac{79}{338}}{ \frac{338-91}{338}} \\\\ = \frac{\frac{79}{338}}{\frac{247}{338}} \\\\ = \frac{79}{338} \times \frac {338}{247} \\\\= \frac{79}{274} \\\\ = 0.28$

The solution for the following system of equations is shown on the graph. What is the solution?

Bingel [31]

The solution is (3 , 4) ⇒ 2nd answer

Step-by-step explanation:

The system of equations can be solved by:

Elimination method
Substitution method

The system of equations is:

y = 3 x - 5 ⇒ (1)

y = $\frac{1}{3}$ x + 3 ⇒ (2)

By using the substitution method substitute y in equation (2) by equation (1)

3 x - 5 = $\frac{1}{3}$ x + 3

Subtract $\frac{1}{3}$ x from both sides

$\frac{8}{3}$ x = 8

Divide both sides by $\frac{8}{3}$

x = 3

substitute x by 3 in equation (1)

y = 3(3) - 5

y = 9 - 5

y = 4

The solution is (3 , 4)
