The zeros of a parabola are 6 and −5. If (-1, 3) is a point on the graph, which equation can be solved to find the value of a in

Elena L [17]

ANSWER

$3= a( - 1 +6)( - 1 - 5)$

EXPLANATION

The equation of a parabola in factored form is

$y = a(x + m)(x + n)$

where 'a' is the leading coefficient and 'm' and 'n' are the zeros.

From the question, the zeros of the parabola are 6 and −5.

This implies that,

$m = 6 \: \: and \: \: n = - 5$

We plug in these zeros to get:

$y= a(x +6)(x - 5)$

If (-1, 3) is a point on the graph of this parabola,then it must satisfy its equation.

We substitute x=-1 and y=3 to obtain:

$3= a( - 1 +6)( - 1 - 5)$

The first choice is correct.

Which inequality correctly compares One-third, Five-sixths, and Three-fifths? One-third < Three-fifths < Five-sixths One-t

lilavasa [31]

Answer:

$\frac{1}{3} \: < \: \frac{3}{5} \: < \: \frac{5}{6}$

Step-by-step explanation:

We want to compare the fractions

$\frac{1}{3}, \frac{5}{6} , \frac{3}{5}$

First, we collect LCM

The LCM of 3,6, and 5 is 30

$\frac{1}{3} = \frac{10}{30} , \\ \frac{5}{6} = \frac{25}{30} , \\ \frac{3}{5} = \frac{18}{30}$

$\frac{10}{30} , \frac{18}{30} , \frac{25}{30}$

This means that

$\frac{1}{3} , \frac{3}{5} , \frac{5}{6}$

Hence,

$\frac{1}{3} \: < \: \frac{3}{5} \: < \: \frac{5}{6}$

Solve the proportion X-16/x+6 = 3/5

BartSMP [9]

Answer:

x = 49

Step-by-step explanation:

Given

$\frac{x-16}{x+6}$ = $\frac{3}{5}$ ( cross- multiply )

5(x - 16) = 3(x + 6) ← distribute parenthesis on both sides

5x - 80 = 3x + 18 ( subtract 3x from both sides )

2x - 80 = 18 ( add 80 to both sides )

2x = 98 ( divide both sides by 2 )

x = 49

Solve by using the square root method.

ehidna [41]

4x^2-8=136 subtract 136 from both sides

4x^2-144...this is a difference of perfect squares so

(2x+12)(2x-12)

x=±6 or as they put it:

{-6, 6}
