Both the given lines in graph intersect at point (5 , -2), the point must satisfy both the equations.

and if we check the options, we will observe that D. option has both the equations that satisfy the given conditions.

that is ~

[tex]\qquad \sf \dashrightarrow \: x + y = 3[/tex]

put y = - 2,we will get :

[tex]\qquad \sf \dashrightarrow \: x - 2 = 3[/tex]

[tex]\qquad \sf \dashrightarrow \: x = 5[/tex]

so, 1st equation satifys the condition. let's check out 2nd one.

[tex]\qquad \sf \dashrightarrow \: x + 2y = 1[/tex]

put y = -2

[tex]\qquad \sf \dashrightarrow \: x + (2 \times - 2) = 1[/tex]

[tex]\qquad \sf \dashrightarrow \: x - 4 = 1[/tex]

[tex]\qquad \sf \dashrightarrow \: x = 5[/tex]

Hence, we can conclude that the Correct choice is D

Which is the completely factored form of 12x4 39x3 9x2? 3x2(x – 3)(4x – 1) 3x2(x 3)(4x 1) 3x(x 3)(4x 1) 3x(x – 3)(4x 1)

Answers

The completely factored expression of 12x⁴ + 39x³ + 9x² is 3x²(4x + 1)(x + 3)

How to factor the expression?

The polynomial expression is given as;

12x⁴ + 39x³ + 9x²

Factor out 3x² from the expression

3x²(4x² + 13x + 3)

Expand

3x²(4x² + 12x + x + 3)

Factorize the expression

3x² * 4x(x + 3) + 1(x + 3)

Factor out x + 3

3x²(4x + 1)(x + 3)

Hence, the completely factored expression of 12x⁴ + 39x³ + 9x² is 3x²(4x + 1)(x + 3)

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. David invested $230 in a savings account that offers a 3% return on the investment. The value of David's investment will be at least $415 after a period of years. Hint: Use the formula A = P(1 + r)t, where A is the amount after t years, P is the amount invested, r is the rate of interest, and t is the time period. Use a calculator to compute the answer, and round it off to the nearest year.

Answers

The value of David's investment will be at least $415 after a period of 20 years

Compound interest

The formula for calculating the compound interest is expressed as:

A = p(1+r)^t

Given the following parameters

A = $415P = $230r = 3% = 0.03

Substitute

415 = 230(1+0.03)^t
415/230 = 1.03^t
1.8043 = 1.03^t
t = ln(1.8043)/ln1.03

t = 20 years

The value of David's investment will be at least $415 after a period of 20 years
