Chapter 3: Q. 4 (page 136)

Solve: $60 x - 900 = - 15 x + 2850 .$

Short Answer

Expert verified

So, $x = \frac{3750}{75} = 50 .$

Step by step solution

Step 1. Given Information

Given that $60 x - 900 = - 15 x + 2850 .$

Step 2. Solution

$60 x - 900 = - 15 x + 2850 60 x + 15 x = 2850 + 900 75 x = 3750 x = \frac{3750}{75} x = 50 .$

Step 3. Final Answer

Hence, $x = 50 .$

Find the real solutions of the equation $2 x^{2} + 7 x - 4 = 0$ .

If $f (x) = x^{2} - 4$ , find $f (- 2) .$

In Problems 21–28, determine whether the given function is linear or nonlinear. If it is linear, determine the equation of the line .

x	$y = f (x)$
-2	$\frac{1}{4}$
-1	$\frac{1}{2}$
0	1
1	2
2	4

If $p (x) = - x + 6,$ then

(a) Determine the slope and y-intercept of each function.

(b) Use the slope and y-intercept to graph the linear function.

(d) Determine whether the linear function is increasing, decreasing, or constant.

Graph the function $f$ by starting with the graph of $y = x^{2}$ and using transformations (shifting, compressing, stretching, and/or reflection). Verify your results using a graphing utility.

Hint: If necessary, write $f$ in the form $f (x) = a (x - h)^{2} + k$ .

$f (x) = x^{2} - 6 x - 1$
