Answer:
Step-by-step explanation:
Answer:
7.A (5,1)
B(5,7)
8. D (0,6)
Step-by-step explanation:
7. One vertex is at (5,4)
Move 3 units either direction in x
(5-3,4) = (2,4)
(5+3,4) = (8,4)
Or move 3 units in the y direction
(5,4+3) = (5,7)
(5,4-3) = (5,1)
If x is less than 2 or greater than 8 it is too far from the one vertex we are given
If y is less than 1 or greater than 7 it is too far away from the one vertex we are given
C cannot be a vertex since y =9
D is not a vertex since the point is (2,6) and not (2,4) which we know is 3 units away
E is not a vertex since the point is (2,1) and not (2,4) which we know is 3 units away
8. The center is (0,0)
The points have to add to a radius of 6
r^2 = 36
The sum of the x^2 and y^2 = 36
3^2 +0^2 = 9
4^2 +2^2 = 16+4 = 20
5^2 +3^2 = 25+9 = 34
0^2+6^2 =36 yes for D
4^2 +4^2 =16+16 = 32
1^2+5^2 = 26
Answer:
ŷ = -0.08522X + 157.7779
The slope = - 0.1
Intercept = 157.8
Step-by-step explanation:
Given the data :

General regression equation :
y = mx + c
Where
y = predicted variable
x = predictor / explanatory variable
m = slope or gradient
c = Intercept
The regression equation obtained ;
ŷ = -0.08522X + 157.7779
To one decimal place :
ŷ = -0.1X + 157.8
The slope = - 0.1
Intercept = 157.8
This expression of yours is problematic in that it's difficult to know which math operations are intended and in which order. In <span>x/2 x-2/4 x-2/2 , which part of the expression is in the numerator, and which in the denominator?
x shows up 3 times. Apparently you meant "the variable x" in "x/2." What about the next "x?" Did you type that in to indicate multiplication or is that "x" a variable also? I think you catch my drift: Your post will need some editing before your readers can understand what you want to do here.
Suppose I interpret your </span><span>x/2 x-2/4 x-2/2 to mean the following:
( x/2 )
---------- * (x-2/2). If that wasn't your intent, please fix it.
x - 2/4
If this interpretation is correct, then you have
x(x-1) 2x(x-1)
---------------- = ------------. If not, please fix it. This rational function
x-1/2 2x -1 cannot be reduced.</span>
