Answer:
a. f(x)=25+0.02x
b. 0 miles
Explanation:
The charges per week to rent a car =$25
There is an additional cost of $0.02 per mile.
Let the number of miles driven during the week = x
(a)The weekly cost, f o rent a car will be:
(b) If the weekly cost to rent the car was $25
f(x)=25
Substitution into f(x) derived above gives:
If the weekly cost was $25, the car was driven for 0 miles (was not driven at all).
Answer:
slope = 1/4
Step-by-step explanation:
To find the slope, I chose two points where the line intersected the graph at an exact point.
Points:
(0, -8)
(4, -7)
Slope is the measure of rise over run, so starting at (0, -8) I went up one and to the right 4 times.
To put this as a fraction, we would have: 1/4
The numerator and denominator are positive because we went up and to the right.
Therefore, the slope is 1/4.
Answer:
The answer is
<h2>( 2 , 1)</h2>Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-4,-8) and (8, 10)
The midpoint is
We have the final answer as
<h3>( 2 , 1)</h3>Hope this helps you
Given:
Sides of triangles in the options.
To find:
Which could NOT be the lengths of the sides of a triangle.
Solution:
Condition for triangle:
Sum of two smaller sides of a triangle must be greater than the longest side.
In option A,
Sides 5 in, 5 in, 5 in are the lengths of the sides of a triangle.
In option B,
Sides 10 cm, 15 cm, 20 cm are the lengths of the sides of a triangle.
In option C,
Sides 3 in, 4 in, 5 in are the lengths of the sides of a triangle.
In option D,
Since, the sum of two smaller sides is less than the longest side, therefore the sides 8 ft, 15 ft, 5 ft are not the lengths of the sides of a triangle.
Therefore, the correct option is D.
