Answer:
30
Step-by-step explanation:
x = 7
( x - 4 )^2 + 3x
= ( 7 - 4 )^2 + 3 ( 7 )
= 3^2 + 21
= 9 + 21
= 30
The answer is 36
Multiply each side by 9
9 times for and 9 times n/9
The n/9 will cancel out so you are left with n= 9 times 4
This comes to 36
To check for symmetry on the x axis, replace y with –y
-y^2 –x(-y) =2
<span> Apply the product
rule, since the equation is not identical tot eh original equation it is not
symmetric about the x axis</span>
<span> Now do the same for y
axis by replacing x with –x</span>
<span> Again using product
rule the equations are not identical, so it is not symmetric about the y axis</span>
<span> To check the origin,</span>
<span> Replace both x &
y with –x & -y</span>
Again using product rule, the equations are not identical so
it is not symmetric about the origin
Answer:
B. x = 2.77
Step-by-step explanation:
3^x = 21
You first look for a base for 21 that is 3 to the power of something.
21 = 3^2.77
So 3^x = 2^2.77
They have the same base so
x= 2.77
