y = something x plus or minus a number

going through each line it isn't a linear pattern ( they don't all have the same difference when subtracted or added together)

so now you play around with quadratic equations ( square roots, powers, etc.)

and you will see that y = x^2 -5

Prove that ax+by+c=0 represent the eqn of straight line

ivann1987 [24]

If we rewrite it as y=mx+d (which can be taken from here from subtracting ax and c from both sides, then dividing b, resulting in y=(-a/b)(x)-c/b. We can then substitute -a/b for m and -c/b for d), if d=0, then we have m as a constant and as we add a specific number to y (that number being m) every time the x value increases by 1, it therefore forms a straight line. If d is not 0, then we simply add d to every single number - this is still a straight line due to that we still add a specific number to y every time x increases by 1 every single time

Jeanine Baker makes floral arrangements. She has 10 different cut flowers and plans to use 6 of them. How many different selecti

Alex Ar [27]

Answer:

210 ways

Step-by-step explanation:

In the question, the combination should be computed.

Number of ways of selection 6 flowers = nCr =10C6

$\frac{n!}{r!(n-r)!}$ = $\frac{10!}{ 6!(10-6)!}$

=3628800/17280

=210

Therefore, there are 210 ways in which 6 flowers can be selected from the available 10 flowers.

Okay first I think you might’ve highlighted incorrectly. You want to make sure the angles match with each other. Next you set up a proportion and solve. I’ll draw this all out for you. I hope this helps! :))
