If f(x) = x and g(x) = 2x + 7, what is<br>f[90X)] when g(x) = 11?

kumpel [21]

$\bf \begin{cases} f(x) = x\\ g(x) = 2x+7 \end{cases}~\hspace{7em}g(x)=11\implies \stackrel{g(x)}{11}=2x+7 \\\\\\ 4=2x\implies \cfrac{4}{2}=x\implies \implies \boxed{2=x} \\\\[-0.35em] ~\dotfill\\\\ f[90x]\implies f\left[90\left( \boxed{2} \right)\right]\implies f(180)=\stackrel{x}{180}$

The square root of 61 is in between 2 integers what are they

swat32

One way is to estimate
1^2=1
2^2=4
3^2=9
4^2=16
5^2=25
6^2=36
7^2=49
8^2=64
the number 61 is between 49 and 64 therefor the square root of 61is between the intigers 7 and 8 or -7 and -8

The perimeter of a rectangle is 46 m if the with were doubled and on length were increased by 5 their perimeter would be 66 what

Kamila [148]

Answer:

18 and 5

Step-by-step explanation:

if 'x' - is the length and 'y' - the width of the rectangle, then

2(x+y)=46 - perimeter of the original rectangle and 2(2x+(y+5))=66 - the perimeter of the new rectangle.

$\left \{ {{x+y=23} \atop {2x+y=28}} \right. \=> \ \left \{ {{x=5} \atop {y=18}} \right.$

Finally, the length is x=5 and the width is y=18.
