Answer:

66 ft

Step-by-step explanation:

model: real life

1 inch : 12 ft

We have 5.5 inches so we need to multiply each side by 5.5 inches

model: real life

1 *5.5 : 12 *5.5

5.5 in: 66 ft

Find an equation of a line with the x- and y-intercepts below. Use exact fractions when necessary.

Ludmilka [50]

Answer:

The line with the x- and y-intercepts below has the following equation:

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

Step-by-step explanation:

The equation of the line has the following format:

$f(x) = ax + b$

We are given two points, we are going to substitute them into the above equation, and find the equation of the line given the conditions.

Solution

Starting from the y-intercept makes the solution easier, since the term a is multiplied by 0

y-intercept -5

This means that when $x = 0, y = f(x) = -5$ , so:

$f(x) = ax + b$

$-5 = a(0) + b$

$b = -5$

For now, the line has the following equation:

$f(x) = ax - 5$

x-intercept 7

This means that when $y = f(x) = 0,x = 7$ , so:

$f(x) = ax - 5$

$0 = 7(a) - 5$

$7a = 5$

$a = \frac{5}{7}$

So, the line with the x- and y-intercepts below has the following equation:

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

If you apply the changes below to the linear parent function, Fx) = x, what is

Inga [223]

Answer: A. G(x)= ax=y= - f(x) is flip over x-axis. Therefore, f(x) =14x would become f(x) =-14x. Therefore, final transformed function f(x)=-14x is vertically stretch by a factor of 14 and flip over the x-axis.
