Answer:

The correct option is a. 8.75.

Step-by-step explanation:

Given:

f(x)=[2.5x] .............................. (1)

Where;

x = 3.5

The function can be evaluated by substituting x = 3.5 into equation (1), we have:

f(3.5) = 2.5 * 3.5

f(3.5) = 8.75

This implies the value of the function is 8.75. Therefore, the correct option is a. 8.75.

A line has a slope of 1and passes through the point

Jobisdone [24]

$\huge\boxed{y=x-3}$

Start with point-slope form, where $m$ is the slope and $(x_1, y_1)$ is a known point on the line.

$y-y_1=m(x-x_1)$

Substitute in the known values.

$y-3=1(x-6)$

Distribute the $1$ to the $(x-6)$ .

$y-3=x-6$

Add $3$ to both sides.

$\boxed{y=x-3}$

Leslie mows lawns to earn money. For each customer, she charges $2.00 for gas and $3.00 per 12 hour of work. Let x represent the

RUDIKE [14]

Answer:

See Explanation

Step-by-step explanation:

Given

$Gas = \$2.00$

$Rate = \$3.00/12hr$

$\begin{array}{ccc}{Row} & {Hours} & {Earnings} & {A} & {2} & { } & {B} & {4} & { } & {C} & {6} &{ } \ \end{array}$ ---- Missing table

Required

Complete the table and plot the graph

First, we determine the equation of the table:

$Gas = \$2.00$

$Rate = \$3.00/12hr$ implies that:

$Rate = \$0.25/hr$

So:

$y = Gas + Rate * x$

$y = 2+ 0.25* x$

$y = 2+ 0.25 x$

To complete the table, we have:

$x = 2$

$y = 2+ 0.25 x = 2+0.25 * 2 = 2.5$

$x = 4$

$y = 2+ 0.25 x = 2+0.25 * 4 = 3$

$x = 6$

$y = 2+ 0.25 x = 2+0.25 * 6 = 3.5$

So, the complete table is:

$\begin{array}{ccc}{Row} & {Hours} & {Earnings} & {A} & {2} & {2.5} & {B} & {4} & {3} & {C} & {6} &{3.5} \ \end{array}$

Banu will build a fence around a rectangular

Solnce55 [7]

Answer:

Step-by-step explanation:

Dimension of the rectangular fence:

Length = 30 ft

Width = 25 ft

Perimeter of the rectangular fence = 2(L + W)

= 2(30 + 25) = 2(55)

Perimeter = 110 ft

Fencing cost per foot = $4.05

Fencing cost for 110 ft = 110 × 4.05 = $445.50
