The function D =25+0.3 X represents the daily dental charge D in dollars for X miles driven

Lady_Fox [76]

Answer:

See Explanation

Step-by-step explanation:

Given

$D = 25 + 0.3X$

The question has missing details; as what's required is not stated.

However, since it is a linear equation, possible questions could be

1. Determine the slope

2. Determine the D-intercept

3. Calculate the amount in dollars for (say) 5 miles

An equation is represented as:

$D = b + mx$

Where

$b = D\ intercept$

$m = slope$

By comparing: $D = 25 + 0.3X$ to $D = b + mx$

$b = 25$ and $m = 0.3$

This means that the slope is 0.3 and the d intercept is 25

To get the amount for 5 miles, we substitute 5 for x in $D = 25 + 0.3X$

$D = 25 + 0.3 * 5$

$D = 25 + 1.5$

$D = 26.5$

The cost of 5 miles is $26

Make use of the above explanation to solve the question

Prove that triangle ABC is Isosceles, given the following points.

Umnica [9.8K]

Answer:

See below

Step-by-step explanation:

Given points:

A (3, -1) , B (9, 2) , C (6, -4)

First, plot the points on the coordinate plane (see attached)

We see that AB and BC look the same. Let's find their length:

AB = $\sqrt{(9-3)^2+(2-(-1))^2} = \sqrt{6^2+3^2} = \sqrt{45} = 3\sqrt{5}$
BC = $\sqrt{(6-9)^2 + (-4-2)^2} = \sqrt{3^2 + (-6)^2} = \sqrt{45} = 3\sqrt{5}$

We showed that AB = BC = 3√5, so the triangle has two sided of the same length, therefore is isosceles.
