A graphing calculator finds the regression line to be
y = 5.5x + 52
Answer:
6.7 = 6 
-0.92= -
-0.1= -
-5.05=-5
Step-by-step explanation:
:-)
First rewrite the decimal as a number with 1 in the denominator.
2nd multiply to remove 2 decimal places by (100/100)
3rd reduce the result of the multiplication
Then simplify the improper fraction

I assume you're asking to convert 114₅ to base 10. We have
114₅ = 1•5² + 1•5¹ + 4•5⁰
114₅ = 25 + 5 + 4
114₅ = 34
Answer:
c
Step-by-step explanation:
y =
x + 2 → (1)
2y = 5x + 4 ( divide through by 2 )
y =
x + 2 → (2)
the 2 equations are the same and will have infinitely many solutions
Answer:
The given equation is -2x^2 = -8x + 8
This can be rewritten as 2x^2 - 8x + 8 = 0
Here the value of a =2, b = -8 and c = 8
Discriminant = b^2 - 4ac
Now plug in the above values in the discriminant, we get
= (-8)^2 - 4*2*8
= 64 - 64
= 0
Here the discriminant is 0, so we will get one real root.
The discriminant is equal to 0, which means the equation has one real number solution.
Hope this will helpful.
Thank you.
