Answer:
9 units squared
Step-by-step explanation:
There are 6 units going up from the origin, and 3 units going right.
Do 6 x 3 = 18
18 divided by 2 because area for triangles is length x width divided by 2.
18 divided by 2 = 9
add units of measurements
The P - intercept of the equation is 28
Solution:
Given equation models the relation between amount of Randy's monthly water bill payment and number of units of water used
P = 28 + 2.54w
Where,
"P" is the monthly water bill payment in dollars
"w" is the number of units of water used
Compare this equation with slope intercept form
Slope intercept form: y = mx + c
Where "m" is the slope of line and "c" is the y intercept
Therefore in given equation, P = 28 + 2.54w
2.54 is the slope and 28 is the P - intercept
The slope, 2.54, means that Randy’s payment increases by $2.54 when the number of units of water he used increases by 1
When "w" increases by 1 , then P increases by $ 2.54
The P –intercept means that if the number units of water Randy used was 0, the payment would be $28
When w = 0 ,
P = 28 + 0
P = $ 28
Thus the P - intercept determines the monthly payment bill
Answer:
The slope, 2.54, means that Randy's monthly water bill payment increases by 2.54 dollars for each unit of water used.
Time is the duration during which any activity or work is performed. Jeanette's sister started 4 hours before the 9:00 pm which is 5:00 pm.
Given-
Jeanette's sister charges $5.50 per hour before 9:00 pm.
Jeanette's sister charges $8 per hour after 9:00 pm.
She finished babysitting at 11:00 pm
She earned total money $38.
Time is the duration during which any activity or work is performed.
Total hour she worked after the 9:00 pm,
Thus she worked total 2 hours after the 9:00 pm. She charges charges $8 per hour after 9:00 pm.Hence money earned by her in 2 hours after 9:00 pm ,
Thus money earned by her in 2 hours after 9:00 pm is $16. The money earned by her before the 9:00 pm is addition of money earned by her before 9:00 pm and after 9:00 pm. Let money earned by her before 9:00 pm is $x. Thus,
Thus the money earned by her before 9:00 pm is $22.
She charges $5.50 per hour before 9:00 pm. Hence the $22 charged by her in hours,
Therefore, hence Jeanette's sister started 4 hours before the 9:00 pm which is 5:00 pm.

Hey there! :D Jeanette's sister started at 5:00 PM. To get that answer, here's what I did: From 5-9 PM, she earned $22. That's because 5.50 x 4 = 22, then from 10-11, she charged $8 which is 8 x 2 = 16 + 22 = $38. Again, she started at 5 PM.
Hope it Helps and makes sense! :D
Answer:
Step-by-step explanation:
We have been given that one winter day,the temperature ranged from a high 20°F to a low -25°F.
To find the degrees by which temperature dropped, we will find difference between the final temperature and initial temperature.
Since our difference is negative, therefore, the temperature dropped 45 degrees Fahrenheit.
