Answer:

A) x = 5.4, x = -1

Step-by-step explanation:

Equations:<em> f(x) = x² - x - 12, g(x) = 3.4x - 6.6</em>

If f(x) = g(x)

Substitute: <em>x² - x - 12 = 3.4x - 6.6</em>

Subtract: x² - 4.4x - 5.4 = 0

Two numbers w/ sum of -4.4x and product of -5.4x²: -5.4x and 1x

Substitute: x² - 5.4x + x - 5.4 = 0

Factor: (x - 5.4)(x + 1) = 0

Solve: x = 5.4, x = -1

Solve the inequality below. Use the drop-down menus to describe the solution and its greah
Solnce55 [7]

Answer:

The solution of the inequality is x ≤ -4. A graph of the solution should have a vertical line passing through x = -4 and be shaded to the left of x = -4

Step-by-step explanation:

-7x + 13 ≥ 41

Subtract 13 from both sides

-7x ≥ 28

Dividing both sides by the -7 changes the inequality sign and we have

x ≤ -4

Hence, the solution of the inequality is x ≤ -4 and the graph of the solution should have a vertical line passing through x = -4 and it should be shaded to the left of x = -4 indicating that only numbers less than or equal to -4 are possible solutions of the inequality.

Hope this Helps!!!

Answer:

c = 35

Step-by-step explanation:

c^{2} = a^{2} + b^{2}

c^{2} = 21^{2} + 28^{2}

c^{2} = 1225

\sqrt{c^{2} } = \sqrt{1225}

c = 35
