– 6x + 11 = – 7 step by step

First let's add 6x to both sides. We do this because the 6x is negative and by adding 6x to both sides, we are isolating the 11 and we are also making the 6x positive, which makes things easier later.

-6x + 11 = -7

+6x          +6x

11 = -7 + 6x

Now let's flip the equation to make it easier to read:

-7 + 6x = 11

And let's add 7 to both sides as we need to isolate the 6x. We are adding 7 because the 7 is negative.

6x = 18

And finally to get the value of x we divide both sides by 6:

x = 3

I hope this helped, and have a great night! :)

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
