range is {- 27, - 15, - 3, 9 }
substitute each of the values from the domain into the equation for x and solve for y
These values are the range
x = - 2 : y = - 12 - 15 = - 27
x = 0 : y = 0 - 15 = - 15
x = 2 : y = 12 - 15 = - 3
x = 4 : y = 24 - 15 = 9
Answer:
22% reduction
Step-by-step explanation:
Find the percent decrease by dividing the difference in amounts by the original amount.
Find the difference:
115 - 90 = 25
Divide this by the original amount:
25/115
= 0.217
So, the percent decrease is 21.7%. Round this to the nearest whole percentage:
= 22
The percent reduction in fuel used was approx. 22%
Answer:
Step-by-step explanation:
164.8+106.09=270.89
Well, 3=2x+10, so that means -7=2x , to solve for x I will just divide, so x= -3.5
If by "long leg lengths" you mean the hypotenuse then the area is 116 sq. units. If you mean the bases of the triangles then the area is 170 sq. units.
If the length of 12 is the hypotenuse, we first must find the base of the triangles using the Pythagorean theorem:
10² + b² = 12²
100 + b² = 144
b² = 44
b = √44 = 6.6
This means we have two triangles and a rectangle. The area of the rectangle is 5(10) = 50 sq. units. The area of each triangle is 1/2(6.6)(10) = 33. Adding all 3 together we have:
50+33+33 = 116 sq. units.
If the 12 is the base, then we have the rectangle with the area of 5(10) = 50 and two triangles each with an area of 1/2(12)(10) = 60:
50+60+60 = 170 sq. units.
