Answer:

5

Step-by-step explanation:

The equation $y=5x+10$ is given in slope-intercept form. Slope-intercept form is a way of writing the equation of a line in the format $y=mx+b$ , such that the coefficient of the parameter (x) is the slope, and constant (b) is the y-intercept. What that essentially means is,

$y = mx + b\\\\m=slope\\b = y-intercept.$

The slope of a line is its rate of change, and the y-intercept is where the graph of the line intersects the y-axis. One can apply this knowledge here by saying that, the equation $y=5x+10$ is given in the slope-intercept form, and the coefficient ( $m$ ) equals ( $5$ ), therefore the slope is ( $5$ ).

Answer:

A. $Area = \frac{1}{2}(2x^2 - 2x - 24)$

B. $Area = 3.75 in^2$

Step-by-step explanation:

A. $Area = \frac{1}{2}bh$

Where,

$b = 2x + 6$

$h = x - 4$

Plug in the values to get a polynomial that represents the area of the tool

$Area = \frac{1}{2}(2x + 6)(x - 4)$

$Area = \frac{1}{2}(2x(x - 4) + 6(x - 4)$

$Area = \frac{1}{2}(2x^2 - 8x + 6x - 24)$

$Area = \frac{1}{2}(2x^2 - 2x - 24)$

B. To find area, when x = 4.5 in, plug in the value of x into the equation for the area of the tool.

$Area = \frac{1}{2}(2(4.5)2 - 2(4.5) - 24)$

$Area = \frac{1}{2}(2(20.25) - 9 - 24)$

$Area = \frac{1}{2}(40.5 - 9 - 24)$

$Area = \frac{1}{2}(7.5)$

$Area = 3.75 in^2$
