Answer:

y=-2x+b

Step-by-step explanation:

Just use the formula y=ax+b, and input -2 as A, and 3, as x, and 2, as y, and then simplify.

Y=-2x+(-3)

Because you still need to find b so you plug in 3,2 into y=Mx+b so you get 2=-2*3+b
And you solve -2*3 = -6 and 2 divided by -6 is -3 so you get y=-2x+(-3)

Paladinen [302]

Divide each term by x and simplify.

(Ok so I don’t make it confusing the first part after “F=“ will be on top The I’ll put the bottom part below oh btw the top and bottom r negative so put the negative sign in front of the fraction)

F= - 21fx+x√x-2x-3(top of fraction)

F=-x^2(bottom of fraction)

You deposit $1500 in a stock account. The account starts losing 2.6% interest annually. How must money do you have after 2 years

Serhud [2]

Answer: M(2) = $1500*(1 - 0.026)^2 = $1423.01

Step-by-step explanation:

Initially in the acount there is $1500

You lose a 2.6% (or 0.026 in decimal form) per year, so after the first year you have:

M = $1500 - 0.026*$1500 = $1461

After other year, you lose oter 2.6%

M = $1461 - 0.026*$1461 = $1423.01

The equation can be writen as:

M(t) = $1500*(1 - 0.026)^t

Where t is the number of years, you can use t = 2 and get:

M(2) = $1500*(1 - 0.026)^2 = $1423.01

Find the 14th term of the geometric sequence 5,-10,20

tamaranim1 [39]

In this specific case, the initial term (a) is 5 and the common ratio (r) is -2

Henceforth, after determining what a and r are, we use the formula for the nth term. Which is:

$a_n = a \times r^{n-1}$

Therefore, the 14th term is :

$\implies 5 \times { (- 2)}^{14 - 1} \\\implies 5 \times {( - 2)}^{13} \\ =\boxed { -40,960}$

Hope it helps!

Help! I don't understand this.

OleMash [197]

Answer:

x > 9.

Step-by-step explanation:

Here it is just simplifying the inequality.

6 - 2/3x < x - 9

Add 2/3x to both sides.

6 < 5/3x - 9

Add 9 to both sides.

15 < 5/3x

Multiply by 3/5.

9 < x

Flip it.

x > 9.
