Given that (-9,-1) is on the graph of f(x) find the corresponding point for the function f(x+3).

Semmy [17]

If you begin with the graph for f(x) and then substitutde x+3 for x, the effect on the graph will be to move the whole graph 3 units to the left.

Given that (-9,-1) is on the graph of f(x), and that we are to move the entire graph 3 units to the left, then the coordinate -9 becomes -9-3, or -12: (-12,-1).

Solve for x PLS HELP NOW

Zepler [3.9K]

Answer:

$x=70$

General Formulas and Concepts:

<u>Pre-Alg</u>

Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

<u /> $\frac{0.35}{\frac{2}{3}x } =\frac{0.45}{x-10}$ <u />

<u />

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

Cross-multiply: $0.35(x-10)=\frac{2}{3} x \cdot 0.45$
Distribute 0.35: $0.35x - 3.5=\frac{2}{3} x \cdot 0.45$
Multiply: $0.35x - 3.5=0.3x$
Isolate <em>x</em> term: $-3.5=-0.05x$
Isolate <em>x</em>: $70=x$
Rewrite: $x=70$

<u>Step 3: Check</u>

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

Substitute: $\frac{0.35}{\frac{2}{3}(70) } =\frac{0.45}{70-10}$
Multiply: $\frac{0.35}{\frac{140}{3} } =\frac{0.45}{70-10}$
Subtract: $\frac{0.35}{\frac{140}{3} } =\frac{0.45}{60}$
Evaluate: $0.0075=0.0075$
