It’s 7:3
Explanation
It’s 7:3 because 28 divided by 4 is 7 and 12 divided by 4 is 3
r > 0 = r is greater than 0
r ≤ 8 = r is less than and equal to 8
0 ≤ r ≤ 8
Answer:
Option C.
Step-by-step explanation:
If a vertical line intersects the x-axis at point (c,0), then the equation of line is x=c.
From the given figure it is clear that it is a vertical line and it intersects the x-axis at (-1,0). There are infinite values of y at x=-1.
So, the equation of given line is
Therefore, the correct option is C.
(x^12)^5=x^(12*5)=x^60
(x^(-2))^9=x^(-18)
x^60*x^(-18)=x^(40) and we need to find x^a such that
x^(42)*x^a=x^(40)^5
x^a=x^(40)^5*x^(-42)
x^a=x^(200)x^(-42)
x^a=x^(200-42)
x^a=x^158
so the missing term is x^158
