Three consecutive even integers are such that the square of the third is 76 more than the square of the second. Find the three i

Arada [10]

Let n represent the interger l, the three consective intergers are represented by

$n$

$n + 2$

$n + 4$

The second one represent

$(n + 2) {}^{2} + 76 =( n + 4) {}^{2}$

Simplify both sides

$n {}^{2} + 4n + 4 + 76 = {n}^{2} + 8n + 16$

${n}^{2} + 4n + 4 = {n}^{2} + 8n - 60$

$4n + 4 = 8n - 60$

$4n + 64= 8n$

$64= 4n$

$n = 16$

The intergers are 16,18,20

Trying to find the y-intercept and got -24. But the graph given doesn't have a number on the y-axis going all the way down to -2

mario62 [17]

Answer:

y = 6x - 24

Step-by-step explanation:

Slope intercept form: y = mx + b.

Fill in x, y, and the slope to solve for b as follows:

First find the slope.

60 - 6

14 - 5

54/9

Slope = 6

y = 6x + b

(6) = 6(5) + b

6 = 30 + b

Subtract 30 from both sides.

-24 = b

y = 6x - 24
