Answer is C. 7:42
Because the numbers from the ratio 3:18 , 18/3 is 6
And from the ratio 7:42, 42/7 is also 6
Because the difference in the ratios are the same, the ratios are equivalent

Another way is that 3:18 can be rewritten as 3/18 which is simplified to 1/6. 7:42 = 7/42 which also equals 1/6.

Both ratios simplified equal 1:6.
None of the other answers simplify to this but C.

Find the domain of the function y = 3 tan(2/3x)

Damm [24]

Answer:

{x∈R | $\frac{2x}{3\pi } +\frac{1}{2}$ , x∉Z}

Step-by-step explanation:

Given the function y=3tan(2/3x)

We know that tangent is a function that's continuous within it's domain but not continuous on all real numbers

Also, the roots of y=3tan(2/3x) is $3\pi n/2$ where n is an integer

Note that the domain of the function cannot be within $3\pi n/2$

Therefore, {x∈R | $\frac{2x}{3\pi } +\frac{1}{2}$ , x∉Z}

Find the equation of the line that passes through he points (2,6) and (-2,4)

stepan [7]

First Find slope by using $\frac{y2-y1}{x2-x1}$

$\frac{4-6}{-2-2} = \frac{-2}{-4} = \frac{1}{2}$

Now use point Slope form to find the equation of the line (y-y₁)=m(x-x₁)
(y-6)= $\frac{1}{2}$ (x-2)
y-6= $\frac{1}{2} x-1$
y= $\frac{1}{2} x+5$ is your equation
