Answer:
<u>First, find the cost function of DoItRight Housekeeping:</u>
- Slope(m) = cost per hour =
<em>The y-intercept(b), representing the initial cost, can be calculated by substituting in values to the function:</em>
<u>Therefore, the function for two companies are:</u>
- The function for DoItRight is
- The function for CleanIt is
When comparing the two functions, it's shown how CleanIt has a greater y-intercept than DoltRight, meaning that CleanIt has a greater initial cost than DotRight. The y-intercept is when the graph intercepts the y-axis, therefore, the coordinates there would be (0, y-value), which, in this case for CleanIt company, will be (0, 16). While CleanIt has a greater y-intercept(initial cost), DoItRight has a greater slope, meaning they cost more per hour.
Answer:
- ( 17 )
Step-by-step explanation:
m = 2
n = 19
m^2
= 2^2
= 2 x 2
= 4
3m
= 3 x 2
= 6
3m - ( m^2 + n )
= 3m - ( m^2 + n )
= 6 - ( 4 + 19 )
= 6 - 23
= - ( 17 )
Answer:
the answer is B
Step-by-step explanation:
5/8 * 15 = 9.375000 exactly. The closest number to 9 is 3, which is below 5. This means to round the number down to the number it is closer to. 9.375 is closer to 9 than any other number, so we round it down to 9. Since Cassidy has 10 feet of string, and she uses the same amount for each bracelet, we can assume that she has enough to make 15 bracelets, possibly even 16.
Answer:
m∠C = 44°
Step-by-step explanation:
In ΔCDE,
m∠C=(4x−16) ∘
m∠D=(6x−1) ∘
m∠E=(4x−13) ∘ .
The sum of angles in a triangle = 180°
Step 1
We solve for x
m∠C + m∠D + m∠E
(4x−16)° + (6x−1)° + (4x−13)° = 180°
4x - 16 + 6x - 1 + 4x - 13 = 180°
4x + 6x + 4x -16 - 1 - 13 = 180°
14x - 30 = 180°
14x = 180+ 30
14x = 210
x = 210/14
x = 15
Step 2
Find m∠C
m∠C = (4x−16)°
m∠C = (4 × 15 - 16)°
m∠C = (60 - 16)°
m∠C = 44°
