Answer:
y = 4x + 12
General Formulas and Concepts:
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
Slope <em>m</em> = 4
y-intercept <em>b</em> = 12
<u>Step 2: Write function</u>
- Substitute [Form]: y = 4x + 12
Answer:
y = 0.15x+77 is the equation linear connecting total cost y and miles driven x
Step-by-step explanation:
Given that the leasing company charged a flat rental fee for the week, plus a charge for each mile driven.
Let flat rental fee be c and cost per mile driven = m and miles driven = x
Total cost =y
Then y = mx+C is the linear equation.
to find m and c, we use the fact that y =110.30 when x = 222
i.e. 110.30 = c+222x
and similarly 99.05 = c+147x
Subtract to eliminate c
11.25 = 75 x
0.15 =x
Substitute in I equation
110.30 = c+222(0.15)
c = 77
y = 0.15x+77 is the equation linear connecting total cost y and miles driven x
Note that while the figure is made up of rectangle and parallelogram, then the area of this figure
1. The area of rectangle is
The vertices of rectangle are points A(-2,-2), B(0,-6), C(8,-2) and F(6,2). Then
Therefore,
2. The area of parallelogram can be calculated using formula
The base of parallelogram is segment CD with length
and the height has length 2 un. Then
3. Now
Answer:
(4/15)
Step-by-step explanation:
1- Multiply the numerators:
2- Multiply the denominators:
3- Thus:
Hope this helps ;)
Answer:
Step-by-step explanation:
8/3=3(c+5/3)
multiply both sides by 3
8=9(c+5/3)
divide both sides by 9
8/9=c+5/3
subtract 5/3 from both sides
c=8/9-5/3
change 5/3 to 15/9
c=8/9-15/9
c=-7/9
