Answer:
y = 7x -48
Step-by-step explanation:
Your answer is correct. You just need to write it in the box without the "y =".
__
The 2-point form of the equation for a line is ...
y = (y2 -y1)/(x2 -1x)(x -x1) +y1
y = (8 -(-6))/(8 -6)(x -6) +(-6)
y = 14/2(x -6) -6
y = 7x -42 -6
y = 7x -48
You probably want your answer to look like ...

Step-by-step explanation:
Answer:
431 and 43
Step-by-step explanation:
Two numbers: y1 and y
Number one: y1 = 10 * y + 1
(10 * y + 1) + y = 474
11y = 473
y = 43
Two numbers: 431 and 43
check: 431 remove 1 (digit) -> 43
431+43=474
When taking square roots, you can't take square roots of negative roots of negative numbers. So, what will work for the domain of u(x) is what makes u(x) zero or more. We can make an inequality for that.
u(x) ≥ 0.
9x + 27 ≥ 0 by squaring both sides
9x ≥ -27
x ≥ -3
So the domain of the function is when x ≥ -3 is true.
Answer:
root 30
Step-by-step explanation:
10/x=x/3
x^2=30
x= root 30
