What are the possible rational zeros of f(x) = x4 + 6x3 − 3x2 + 17x − 15? (2 points)

1 answer:

8 0

Solve for x. The multiplicity of a root is the number of times the root appears.

x= -6.847415 (multiplicity of 1)
x= 0.793705 (multiplicity of 1)

James is at a gift sale where everything costs $4 (tax included).

pantera1 [17]

Answer:

5 gifts

Step-by-step explanation:

Given information:

Cost of one gift = $4
Total money = $50
Money left after purchasing gifts = at least $28

Let x = greatest number of gifts James can buy

Create an inequality with the given information:

⇒ 50 - 4x ≥ 28

<u>Solve the inequality</u>

Add 4x to both sides:

⇒ 50 - 4x + 4x ≥ 28 + 4x

⇒ 50 ≥ 28 + 4x

Subtract 28 from both sides:

⇒ 50 - 28 ≥ 28 + 4x - 28

⇒ 22 ≥ 4x

Divide both sides by 4

⇒ 22 ÷ 4 ≥ 4x ÷ 4

⇒ 5.5 ≥ x

⇒ x ≤ 5.5

We must <u>round down</u> to 5 as if James buys 6 gifts, he will only have $26 remaining. Therefore, the greatest number of gifts James can buy is <u>5 gifts</u>.

the Spanish club is selling churros as a fundraiser. If its goal is to raise at least $150, how many churros must it sell at $1.

nekit [7.7K]

Let

x-------> the number of churros sold

we know that

$1.25x \geq 150$ -----> inequality that represent the situation

Solve for x

Divide by $1.25$ both sides

$x \geq 150/1.25$

$x \geq 120\ churros$

therefore

<u>the answer is</u>

The minimum number of churros that must be sold is $120$

There are 12 more apples than oranges in the basket of 36 apples and oranges. How

anygoal [31]

Step-by-step explanation:

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>

Total number of fruits=36

Let

the number of oranges =x

The number of apples=x+12

${:}\leadsto$ $\sf x+x+12=36$

${:}\leadsto$ $\sf 2x+12=36$

${:}\leadsto$ $\sf 2x=36-12$

${:}\leadsto$ $\sf 2x=24$

${:}\leadsto$ $\sf x={\dfrac {24}{2}}$

${:}\leadsto$ $\sf x=12$

Number of Apples =12+12=24
