10. Write an equation in point-slope form and slope-intercept form for the line.
olga2289 [7]

We can use the points (2, -2) and (4, -1) to solve.

Slope formula: y2-y1/x2-x1

= -1-2/4-(-2)

= -3/6

= -1/2

Point slope form: y - y1 = m(x - x1)

y - 2 = -1/2(x + 2)

Solve for y-intercept.

-2 = -1/2(2)  + b

-2 = -1 + b

-2 + 1 = -1 + 1 + b

-1 = b

Slope Intercept Form: y = mx + b

y = -1/2x - 1

______

James wants to invest $12,000. He can invest the money at 7.2% simple interest for 30 yr or he can invest at 6.8% with interest
Sever21 [200]

Over time, compound interest at any rate will outperform simple interest. When the rates are nearly equal to start with, compound interest will be greater in very short order. Here, it takes less than 1 year for compound interest to give a larger account balance.

In 30 years, the simple interest will be

... I = P·r·t = 12,000·0.07·30 = 25,200

In 30 years, the compound interest will be

... I = P·(e^(rt) -1) = 12,000·(e^(.068·30) -1) ≈ 80,287.31

_____

6.8% compounded continuously results in more total interest

Write the first six terms of the sequence.
butalik [34]

Step-by-step explanation:

1st term = -n²+6

= -(1)²+6

= -1+6

=5

2nd term = -(2)²+6

= -4+6 = 2

3rd term= -(3)²+6

=-9+6 = -3

4th term= -(4)²+6

= -16+6 = -10

5th term = -(5)²+6 = -25+6 = -19

6th term = -(6)²+6 = -36+6 = -30

5,2, -3,-10,-19, -30

What is the product?<br> (38b* )-822
sergey [27]

Answer:

\boxed{\sf D)\:-24a^3b^7}

Step-by-step explanation:

\sf (3a^2b^4)(-8ab^3)

We'll use rule of exponents to simplify expression.

\sf 3^1a^2b^4(-8)^1a^1b^3

Now, use the commutative property of multiplication.

\sf 3^1(-8)^1a^2a^2b^4b^4

In order to multiply power of the same base, we add their exponents.

\sf 3^2(-8)^1a^{2+1}b^{4+3}

→ Add exponents:

\sf 3^1(-8)^1a^3b^7

→ Multiply 3* -8

\sf -24a^3b^7
