1)
evaluate when x = 6
5 + x
so when x = 6 then 5 + 6 = 11
answer

11

2)
2/6
in lowest term = 1/3 (divide top and bottom by 2)

3)
evaluate when x = 1
8 + x
so when x = 1 then 8 + 1 = 9
answer: 9

4)
14/48
lowest term = 7/24 (divide top and bottom by 2)

Due: Today @11:59 <br> (Need) Explanation 3-5 sentences of how you got the answer

kifflom [539]

You can use the pythagorean theorem.

a^2+b^2=c^2

a=9

b=b

c=41

9^2+b^2=41^2

81+b^2=1681

b^2=1600

b=+/-40

but since this is a geometric scenario, answers will only lie in the positive real number set. That's why answer is +40 or C.

Identify the quadratic function(s). (Select all that apply.)

Katen [24]

General Idea:

The quadratic function of the form $ax^2+bx+c=0$ .

Applying the concept:

Simplifying the equation in option A, we get...

$A) \; 8 - 5x = 4(3x - 1) \\Distributing \; 4 \; in \; right \; side \; of \; the \; equation. \\ \\ 8 - 5x = 12x - 4\\ The \; equation \; is \; a \; linear \; equation \; with \; variable \; on \; both \; sides.$

Simplifying the equation in option B, we get...

$B) \; \; (4a + 2)(2a - 1) + 1 = 0\\ Multiplying \; First \; \; Outer \; \; Inner \; \; Last \; terms\; in\; the \; left \; side.\\ \\ 4a \cdot 2a + 4a \cdot -1 + 2 \cdot 2a + 2 \cdot -1 + 1 = 0\\ \\ 8a^2-4a+4a-2+1=0\\ Combining \; like \; terms \; \\ \\ 8a^2 - 1 = 0\\ Above \; is \; a \; Quadratic \; Equation!$

Simplifying the equation in Option C, we get...

$C)\; \; 2y + 2(3y - 5) = 0\\ Distributing \; 2 \; in \; left \; side\\ \\ 2y+6y-10=0\\ Combining \; like \; terms\\ \\ 8y - 10 = 0\\ Above \; Equation \; is \; linear \; equation$

Simplifying the equation in Option D, we get

$D) \;2b(b - 7) + b = 0\\ Distributing \; 2b\; in \;the \;left\; side \;of \;the\;equation\\ \\ 2b \cdot b - 2b \cdot 7+b=0\\ Simplify \; in \; the \; left \; side \; of \; the \; equation\\ \\ 2b^2-14b+b=0\\ Combine \; like \; terms\\ \\ 2b^2-13b=0\\ Above \; equation \;is \;a \; Quadratic\;Equation!$

<u>Conclusion:</u>

Option B) & Option D) are quadratic equation!

Bob Rohrman is offering a 2017 Toyota Camry for $29,000. If you have a 7% down payment and are able to borrow the rest at a 2.99

Yakvenalex [24]

Monthly installment payment is $597 .Total payments is $28,649

Step-by-step explanation:

Down payment = $29,000×7 ÷100= $2,030

Loan amount = $29,000 - 2,030 = $26,970

Interest rate = 2.99%

Repayment period = 48 months (4 years)

simple interest formula: A = P(1 + rt) where P is the Principal amount of money to be invested at an Interest Rate R% per period for t Number of Time Periods.

= 26,970 (1+0.0299) × 4) +p =$28,648.51

$= 26,970 (1+0.0299) × 4) +p =$28,648.51$

Monthly payment = $596.84 (or) $597 (rounded off)

$Monthly payment = $596.84 (or) $597 (rounded off)$

Total payments is $28,649
