As x increases from 9 to 12 (a change of 3), y increases from -2 to 0 (a change of 2). Thus, the slope of this line is 2/3.
Subbing this info and the coordinates of one of the points into y = mx + b, we get:
-2 = (2/3)(9) + b. Solving for b: b = -2 -18/3 = -8. Then the equation of this line is:
y = (2/3)x - 8.
Check by subst.: Does (12,0) satisfy this equation? 0 = (2/3)(12) - 8? Yes.
Hi there!
To find the area of the new rectangle, we need to add 2 to the length, and find the area.
7 + 2 = 9
9 * 2 = 18
The new area of the rectangle is 18 square feet.
Hope this helps!
Answer:
228 cups
Step-by-step explanation:
the cups each person will eat can be found by dividing the total number of trail by the number of people who went on the hike
total number of people on the hike = 4
total cups of trail = 912
912 / 4 = 228 cups
There is an app called socratic, also if this assignment goes with a text book there is an app called sladder that has all textbook answers with work
Answer:
Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
91% = 91/100 = 91 ÷ 100 = 0.91.
100% = 100/100 = 100 ÷ 100 = 1.
Decrease number by 91% of its value.
Percentage decrease = 91% × 843
New value = 843 - Percentage decrease
Calculate the New Value
New value =
843 - Percentage decrease =
843 - (91% × 843) =
843 - 91% × 843 =
(1 - 91%) × 843 =
(100% - 91%) × 843 =
9% × 843 =
9 ÷ 100 × 843 =
9 × 843 ÷ 100 =
7,587 ÷ 100 =
75.87
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 843 =
75.87 - 843 =
- 767.13
Proof.
Calculate percentage decrease:
Percentage decrease =
91% × 843 =
91 ÷ 100 × 843 =
91 × 843 ÷ 100 =
76,713 ÷ 100 =
767.13
Step-by-step explanation:
