Answer:
y = x - 9
Step-by-step explanation:
Keep in mind that the lines t and u are perpendicular, which implies that their slopes are negative reciprocals of one another. The negative reciprocal of the slope -1 of line t is +1.
Thus we need to find the equation of line u, knowing that the slope of this line is +1. Starting with the slope-intercept form y = mx + b, we find b:
y = mx + b becomes
-8 = (+1)(-1) + b, or -8 =-1 + b. Then b = -9, and the desired equation is
y = x - 9
You solve the equation for x. First, subtract 7 from both sides.Then subtract 3x from both sides. Then you should get 2x = 16. Divide both sides by two, and you will get x=8.
Answer:
I think you mean this :
Or,
Square root of x-5=6 is :
Get Y by itself, so move X
Equation should look like 1/5y= x-6
Multiply by 1/5
Y = 5x-30
Answer:
Step-by-step explanation:
we know that
