Which graph shows the solution to the inequality -3x-7x&lt;20
hjlf
A graph of this inequality would be a number line, with the number -2 circled (not filled in), and the number line to the right of -2 shaded.

To solve this, you will combine like terms first:

-3x-7x < 20
-10x < 20

Divide both sides by -10:
-10x/-10 < 20/-10

When you divide an inequality by a negative number, you flip the inequality symbol:

x > -2

Answer:

b=\frac{1}{6}

Step-by-step explanation:

In f(x)=a\cos(b(x-c))+d, b represents a constant related to the period of the function. Here's how it's related:

b=\frac{2\pi}{T}, where T is the period of the function.

We're given T=12\pi, so solving for b:

b=\frac{2\pi}{12\pi}=\boxed{\frac{1}{6}}

Marco was shopping for markers and lead pencils. The cost of markers is $4, and the cost of each lead pencil is $3. If Macro can
never [62]

This shows that Marco can buy at most 5 pencils

<h3>Inequalities</h3>
  • Let the price of each pencil Marco can  buy be "x"

If the cost of markers is $4, and the cost of each lead pencil is $3 with at most $15 spent, hence;

  • 4 + 3x ≤ 15

Subtract 4 from both sides

3x  ≤ 15

x ≤ 15/3

x ≤ 5

This shows that Marco can buy at most 5 pencils
