The answer will be 30 feet wide because 15+15 =30

94-30=60
30 because there are four sides to a rectangle and two of them are 15 feet (wide) so 15+15=30

If a data set haas a regression line equation of y=3x+15, what is the predicted values at x=2

nexus9112 [7]

X = 21
if you put in 2 for x you:
1. multiply 3 and 2 to get 6
2. and you then add 6 and 15

y = 3(2) + 15
y = 6 + 15
y = 21

Need help on this math problem!!!

Colt1911 [192]

Answer:

$(fof^{-1})(x)=x$

Step-by-step explanation:

Composition of two functions f(x) and g(x) is represented by,

(fog)(x) = f[g(x)]

If a function is,

f(x) = (-6x - 8)² [where x ≤ $-\frac{8}{6}$ ]

Another function is the inverse of f(x),

$f^{-1}(x)=-\frac{\sqrt{x}+8}{6}$

Now composite function of these functions will be,

$(fof^{-1})(x)=f[f^{-1}(x)]$

= $[-6(\frac{\sqrt{x}+8}{6})-8]^{2}$

= $[-\sqrt{x}+8-8]^2$

= $(-\sqrt{x})^2$

= x

Therefore, $(fof^{-1})(x)=x$

Round 248,739 to the nearest hundred

vampirchik [111]

Look at your hundredth spot which is where the 7 is. So…

248, 739

Since 3 is not 5 or higher you cant round 7 up to 8. So your correct answer is 248,700

Hope this helps!
