Answer:

= x^2 + 3x - 10

Step-by-step explanation:

in factored form, find the equation where plugging x in will result in 0

plugging -5 or 2 into (x + 5)(x - 2) will result in 0

to change this from factored to standard form, FOIL

when you FOIL, (a + b)(c + d) = ac + ad + bc + bd

(x +5)(x - 2)

= (x * x) + (x * -2) + (5 * x) + (5 * -2)

= x^2 -2x + 5x - 10

= x^2 + 3x - 10

Answer:

(x + 5)(x - 2) \\ x(x - 2) + 5(x - 2) \\  {x}^{2}  - 2x + 5x - 10 \\  =  {x}^{2}  + 3x - 10

S $1,595 deposit for 10 years at a simple interest rate of 8%
o-na [289]

Answer:

$2,871.00

Step-by-step explanation:

Calculation:

First, converting R percent to r a decimal

r = R/100 = 8%/100 = 0.08 per year.

Solving our equation:

A = 1595(1 + (0.08 × 10)) = 2871

A = $2,871.00

The total amount accrued, principal plus interest, from simple interest on a principal of $1,595.00 at a rate of 8% per year for 10 years is $2,871.00.

Find the midpoint of the line segment joining the points R(3,2) and S(-5,5).
inessss [21]

The x coordinates are 3 and -5. They add to 3+(-5) = -2

Cut this in half to get -2/2 = -1

The x coordinate of the midpoint is x = -1

-------------------

The y coordinates are 2 and 5. They add to 2+5 = 7.

Then we cut this in half to get 7/2 = 3.5

The y coordinate of the midpoint is y = 3.5

-------------------

Overall, the midpoint is (-1, 3.5)

<h3>Answer: (-1, 3.5) which is the same as (-1, 7/2)</h3>
