Log3 9=2
Explanation:
logo a= n <—> a = b^n
—-> 3^2 = 9 —> log3 9= 2
f(5) is -1
Step-by-step explanation:
- Step 1: Given f(x) = -2x + 9, find f(5)
f(5) = -2 × 5 + 9 = -10 + 9 = -1
3/2(x - 10 ) = 1/2 x + 5
expand by using distributive property
3/2 x - 15 = 1/2 x + 5
subtract (1/2 x ) on both sides
x - 15 = 5
add 15 on both sides
x = 20
answer
C. x = 20
<h2>answer;</h2><h2>B) 12</h2>
<h2>_________</h2><h2><em>explanation</em><em>:</em><em>:</em><em>:</em></h2>
after adding both equation
we \: get..
<h2>
{x}^{2} + xy + {y}^{2} + xy = 62 + 82 </h2><h2>
x^2 + y^2 + 2xy = 144 </h2><h2>
(x + y)^2 = 144 </h2><h2>
(x + y) = sqrt{144} </h2><h2>
x + y = 12</h2>

0.329 is a rational number because the decimal stops. If it had continued on and on with no particular pattern, it would have been irrational. It can be a fraction too (329/1000)...
127.5 is a rational number because again the decimal ends. It can also be converted into a fraction which is another sign that it is rational (127 1/2)...
-89 is a rational number because negatives are rational numbers. It is also in the category of an integer, which means that is a rational number also...
The last one is a non-perfect square, which means no number squared could ever give you 101. When you solve for it, it is also a non-terminating decimal.
