Point slope form and standard form

Answers

The point slope form, , is useful in situations involving slope and the location of one or more points. The standard form, , is usually easier to use when we need to make algebraic calculations. When needs or knowledge change, we can convert an equation from one form into another.

The slope-intercept form (not asked for) is the y=mx+b form, where m is the slope and b is the y-value of the y-intercept (0,b).
This form only works if you have both the slope and y-intercept.

If you have the slope and some other point on the line, say (x1, y1), then the point slope form is:
y - y1 = m ( x - x1 )

So, if you have a slope of 7 and a point (2, -6), then your point-slope form would be:
y - (-6) = 7 ( x- 2) or y+6=7(x-2)

Now standard form is the Ax+By=C format. You can turn any slope-intercept equation or point-slope equation into that form by distributing everything out and getting the x’s and y’s to the left side. Often you’ll also make sure you don’t have any fractions.

Taking the last answer I had, y+6=7(x-2), I’d put this into standard form by distributing:
y+6=7(x-2)

y+6 = 7x - 14

Then move 7x to the left by subtracting and move 6 to the right by subtracting:

-7x + y = -20

Solve for n in the literal equation a(n − 5) + 6 = bn.

Answers

Answer:

(6-5a)/(b-a) = n

Step-by-step explanation:

a(n − 5) + 6 = bn

Distribute

an -5a +6 = bn

Subtract an from each side

an -5a+6 -an = bn-an

6-5a = bn-an

Factor out n

6-5a = n(b-a)

Divide each side by (b-a)

(6-5a)/(b-a) = n

Answer:

[tex]a(n - 5) + 6 = bn \\ an - 5a + 6 = bn \\ an - bn = 5a - 6 \\ n(a - b) = 5a - 6 \\ n = \frac{5a - 6}{a - b} \\ thank \: you[/tex]

Cameron has a bag that contains one silver (S) and one gold (G) marble. The marbles are the same size. Cameron chooses one marble at random and then puts it back in the bag. Then he chooses a second marble. The outcome "GS" means that a gold marble was chosen first and a silver marble was chosen second.

Answers

Answer:

(SS,SG,GS,GG) Probability 0.25

Step-by-step explanation:

i don't know how to do this

Heyo!

So, first things first:

Based on the data shown, it appears that Cameron has 1/4 a chance to really recieve any combo of the following. Hence, he can get SS, SG, 6S, GG. So, each chance he picks, he has a 0.25 chance of probably recieving any of the combo. So, the outcome order is (SS, SG, GS, GG) and the probability for each is 0.25.

It hard to really describe how to write it out without an image, but I hope this helps! Pls, lmk if it does! Good luck!

HELPPP?!!! What is the value of f(-2) and f(3)

Answers

Step #1 for both: figure out which interval your x-value fits into.
For f(-2), x=-2 and -2 fits with x ≤ -2, the top interval.
For f(3), x=3 and 3 fits into -2 < x ≤ 3, the middle interval.

Step #2 for both, plug in your x-value to the piece of the function that fits with that interval.
For f(-2), we know x≤-2, so we use 2x+8 to evaluate x=-2.
For f(3), we know -2
f(-2) = 2(-2)+8 = -4+8 = 4

f(3) = (3)^2 -3 = 9-3 = 6
