Which system is equivalent to
3x2 - 4y? - 25
1-6x2 - 2y2 - 11
3x2-4y? - 25
[12x2+4y? - 22
| 3x2-4y2 - 25
1-12x2 + 4y2 - 22
| 6x2 – by2 - 25
1-6x² – 2y² = 11
bx2 - 8y2 - 50
|-6x² – 2y² = 11

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

step-by-step explanation:

i just know the internet

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
