The y/x values all have the same ratio, 2/5. The line is
y = (2/5)x
Answer:
Every fifth rose in each row of roses
Step-by-step explanation:
<em>Answer</em>
B) y = 3
<em>Step-by-step explanation</em>
Given the system of equations:
Isolating x from equation 1:
Substituting equation 3 into equation 2 and solving for y:
We have the function 
and we want to find a function that has the same y-intercept than the previous function.
First, let's find the y-intercept by subtituting 0 for 'x'.
Now that we found that y-intercept =-3, any lineal function of the type: 
will have the same y-intercept. Where 'a' can take all the real values.
Also, any quadratic function of the type: 
will have the same y-intercept. Where 'a' and 'b' can take all the real values.
Assuming these are 4^(1/7), 4^(7/2), 7^(1/4) and 7^(1/2), the conversion process is pretty quick. the denominator, or bottom, of your fraction exponent becomes the "index" of your radical -- in ∛, "3" is your index, just for reference. the numerator, aka the top of the fraction exponent, becomes a power inside the radical.
4^(1/7) would become ⁷√4 .... the bottom of the fraction becomes the small number included in the radical and the 4 goes beneath the radical
in cases such as this one, where 1 is on top of the fraction radical, that number does technically go with the 4 beneath the radical--however, 4¹ = 4 itself, so there is no need to write the implied exponent.
4^(7/2) would become √(4⁷) ... the 7th power goes with the number under your radical and the "2" becomes a square root
7^(1/4) would become ⁴√7 ... like the first answer, the bottom of the fraction exponent becomes the index of the radical and 7 goes beneath the radical. again, the 1 exponent goes with the 7 beneath the radical, but 7¹ = 7
7^(1/2) would become, simply, √7
