Answer:
6y/8+12-12=84-12
6y/8=72
8/6*6y/8=72*8/6
y=96
Step-by-step explanation:
first u get rid of the 12 by subtracting it from both side until u get 6y/8 =72. Then to isolate y u have to multiply the reciprocal of 6/8(8/6) by 6y/8, and u do the same thing to the other side. Then when they cancel out each other y would be left to equal 96.
Answer: (1, √15) and (1, -√15)
Step-by-step explanation:
A circle centered at the point (a, b) of radius R can be written as:
(x - a)^2 + (y - b)^2 = R^2
In this case we have:
"A circle is centered at the origin (0,0) and has a radius of 4 units"
Then the equation for this circle is:
x^2 + y^2 = 4^2 = 16.
Now, we want to find the points where x = 1, then we can replace that value and solve the equation for y.
1^2 + y^2 = 16
1 + y^2 = 16
y^2 = 16 - 1 = 15
y = +-√15
Then the two points that have the x-coordinate equal to 1 are:
(1, √15) and (1, -√15)

Answer:
1.26
Step-by-step explanation:
geometric mean =sqrt((4/5)*2)=sqrt(1.6)=1.26
Answer:
x = 6 is a solution of x - 1 
7.
Step-by-step explanation:
First, plug in x = 6 into the inequality.
x - 1 7 for x = 6
6 - 1 7
Now, solve.
6 - 1 = 5
5 7
The statement above is true, so x = 6 is a solution to x - 1 7.
