90 degree rotation clockwise : (a,b) --> (b,-a)
so... (24,-15) --> (-15,-24) is a 90 degree clockwise rotation
Answer: (4, -2)
<u>Step-by-step explanation:</u>
Inverse is when you swap the x's and y's: (-2, 4) --> (4, -2)
Answer:
Extrapolation
Step-by-step explanation:
Given
Explanatory variable
Response variable
Required
Predicting y outside range of x is called
This is referred to as extrapolation.
Take for instance, the range of x is: 1 - 9
You have extrapolated when, 10 is assumed to be the value of x and this value is entered in an equation to predict y.
Answer:
B. 1,251 ft²
Step-by-step explanation:
The walkway can be divided into 4 rectangles as shown in the attachment below.
Calculate the area of the walkway part by part.
Part 1 and Part 2:
Length = 100 ft + 4½ ft + 4½ ft = 109 ft
Width = 4½ ft
Area of part 1 and 2 = 2(length * width)
= 2(109*4½) = 981 ft²
Part 3 and Part 4:
Length = 30 ft
Width = 4½ ft
Area of part 1 and 2 = 2(length * width)
= 2(30*4½) = 270 ft²
Area of the walkway = 981 + 270 = 1,251 ft²
Answer:
x=8
Step-by-step explanation:
5(3x-4)-6x=3(3x-4)
First, remove the brackets that's,
15x-20-6x=9x-12
Then collect like terms that's,
15x-6x-9x= -12+20
that's,
9x-9x=8
Therefore,
x=8
