This is all about operations priority! We have to perform the operations in the right order, remembering that parentheses come first, then powers, then multiplications and then additions:
Start with
Perform the operations inside parenthesis first:
Perform the square:
Perform the product:
Perform the sum:
Note: you have an extra parenthesis at the end, and none of the options meets the result. I'm afraid that there's a typo in the question, but this should still give you a valid strategy to solve the actual exercise.
Answer:
Does not go
Step-by-step explanation:
So the equation is
M(-10, 15)
The graph Does not go through point M bcz when the value of x = - 10 then the value of y is 6, not 15
Answer:
x=1
Step-by-step explanation:
log_4(x + 3) + log_4x = 1
We know that loga(b) + loga(c) = loga(bc)
log_4(x + 3)x = 1
Raise each side to the base of 4
4^log_4(x + 3)x = 4^1
(x+3)x = 4
x^2 +3x = 4
Subtract 4 from each side
x^2 +3x -4 = 0
Factor
(x+4) (x-1) =0
Using the zero product property
x= -4 x=1
But x cannot be negative since logs cannot be negative
x=1
Answer:
Step-by-step explanation:
Use distributive property.
Answer:
2
Step-by-step explanation:
We have y=x²-2x+2
Plug in 0 for x
y= 0²-2(0)+2
y=2
Hope this helps
