Answer:

Options (2), (4) and (6)

Step-by-step explanation:

Given system of equations is,

f(x) = x² - 5x + 7

g(x) = 2x + 1

By equating both the functions,

f(x) = g(x)

x²- 5x + 7 = 2x + 1

x² - 5x - 2x + 7 - 1 = 0

x² - 7x + 6 = 0

x² - 6x - x + 6 = 0

x(x - 6) - 1(x - 6) = 0

(x - 1)(x - 6) = 0

x = 1, 6

For x = 1,

g(x) = 2x + 1

g(1) = 2(1) + 1

     = 3

For x = 6,

g(6) = 2(6) + 1

      = 13

Common points (solutions) of both the functions 'f' and 'g' are (1, 3) and (6, 13).  

Both the solutions lie in quadrant 1.

x-coordinate of the solution (1, 3) is x = 1.

y-coordinate of the solution (1, 3) is y = 3.

Therefore, options (2), (4) and (6) are the correct options.

Hi, can someone help with these two questions ASAP! (Ignore the multiple choice I circled, not sure if it’s correct)
Sindrei [870]

Answer:

1) D. y = -\frac{3}{2}\cdot x^{12} -7\cdot x^{5}+\frac{2}{3}\cdot x -10

2) E. The coefficient of x is -16.

Step-by-step explanation:

1) A polynomial is an algebraic expression of the form p(x) = \Sigma \limits_{i = 0}^{n} c_{i}\cdot x^{i}, where n is the grade of the polynomial. In this case, the only equation that satisfies this definition is:

y = -\frac{3}{2}\cdot x^{12} -7\cdot x^{5}+\frac{2}{3}\cdot x -10

Correct answer: D

2) Let p(x) = (2\cdot x + 1) \cdot (5\cdot x^{3}-8\cdot x +4), we proceed to expand the expression by algebraic means:

p(x) = (2\cdot x + 1)\cdot (5\cdot x^{3}) -(2\cdot x +1)\cdot (8\cdot x) + 4\cdot (2\cdot x + 1)

p(x) = 10\cdot x^{4}+5\cdot x^{3}-16\cdot x^{2}+4

We see that coefficients for x^{2} and x are -16 and 0, respectively. Hence, the incorrect answer is E.

Which of the following situations results in an answer of 23 ? Select three that apply.
Nata [24]

Answer:

The first, second, and fourth questions.

Step-by-step explanation:

None of these result in an answer of 23, so I'm assuming that you meant 2/3.

<em />

<em>"Two gallons of water are needed to fill 3 fish tanks of equal size. How many gallons of water are required for each tank?"</em>

2 gallons divided between 3 tanks is 2 divided by 3, so 2/3.

<em />

<em>"Three cats share 2 cans of tuna. How much of a can does each cat receive?"</em>

2 cans divided between 3 cats - it's the same as the above problem, just with cats and tuna cans instead of tanks and gallons of water. Each cat gets 2/3 of a can.

<em />

<em>"Two bags of bird seed are split among 5 parrots. What fraction of a bag does each parrot receive?"</em>

2 bags divided between 5 parrots would be 2/5 of a bag for each parrot.

<em />

<em>"Two apples are split among 3 people. How much of an apple does each person receive?"</em>

Two apples split among 3 people - like the first 2 questions, this also equals 2/3.

<em />

<em>"Three dogs each drink 2 cups of water. How many cups of water do the dogs drink in all?"</em>

Three dogs EACH drink 2 cups of water means that the answer is 2*3=6 cups.

<em>"Three cupcakes are divided among 2 children. How much of a cupcake does each child receive?"</em>

Three cupcakes are split between 2 children - they will each get 3/2 of a cupcake, or 1 1/2.
