Answer:

Step-by-step explanation:

$4 \frac{1}{5} \div \frac{2}{3} = \frac{21}{5} \div \frac{2}{3} = \frac{21}{5} \times \frac{3}{2 } \\ \\ = \frac{63}{10} = 6 \frac{3}{10}$

Solve for x: <br> 4(x + 2) = 3(x - 2)

Pani-rosa [81]

Answer:

x = -14

Step-by-step explanation:

Step 1: Write equation

4(x + 2) = 3(x - 2)

Step 2: Solve for <em>x</em>

Distribute: 4x + 8 = 3x - 6
Subtract 3x on both sides: x + 8 = -6
Subtract 8 on both sides: x = -14

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

4(-14 + 2) = 3(-14 - 2)

4(-12) = 3(-16)

Write a cubic function whose graph goes through the points: (-5, 0) (1, 0) (2, -2) (4, 0)

Free_Kalibri [48]

Answer:

f(x) = $\frac{1}{7}(x+5)(x-1)(x-4)$

Step-by-step explanation:

Let the equation of the give cubic function is,

f(x) = p(x - a)(x - b)(x - c)

Here, a, b, c and d are the x-intercepts of the given graph.

Since, x-intercepts given in the graph are x = -5, 1 and 4,

Equation of the curve will be,

f(x) = p(x + 5)(x - 1)(x - 4)

Since, the graph of this function passes through (2, -2) also

-2 = p(2 + 5)(2 - 1)(2 - 4)

-2 = -p(14)

p = $\frac{2}{14}$

p = $\frac{1}{7}$

Therefore, equation will be,

f(x) = $\frac{1}{7}(x+5)(x-1)(x-4)$
