Answer:
x<13
Step-by-step explanation:
To solve this, we want to have the isolate the variable x on the left side, by itself without a coefficient. All we have to do to do this is add 4 to both sides, cancelling out the -4 and getting x<13
Answer:
x = 13 + y
Step-by-step explanation:
Simplify:
-4 + x = y + 9
Reorder the terms:
-4 + x = 9 + y
Move all terms containing x to the left all other terms to the right
Add 4 to each side of the equation
-4 + 4 + x = 9 + 4 + y
Combine like terms: -4 + 4 = 0
0 + x = 9 + 4 + y
x = 9 + 4 + y
9 + 4 = 13x = 13 + y
Answer:
x = 13 + y

Answer:
yes , keiko is correct.
sin^(-1)x = -sin^1
Answer:
Keiko is wrong
Step-by-step explanation:
Keiko is incorrect
When n is positive, 1^n will always be 1
but........ (-1)^n will not always be -1
This is because there are parenthesis around -1
So n is even, then it will be 1 not -1
For example, n = 4
You will do -1 * -1 * -1 * -1 which is 1 not -1
but if n = 3
You will do -1 * -1 * -1 which is -1
Therefore, the second statement is incorrect resulting in Keiko being wrong

i got 22 for a but am stuck on b & c :(
please explain what u r doing
Answer:
b) [tex]f^-1(x)[/tex]= ∛(4x-24)
c)2
Step-by-step explanation:
these ones are inverse functions
change the f(x) for y and make x the subject
y= x³/4 +6
(y-6)x 4 = x³
∛(4y-24)= x
then put x back were y is
[tex]f^-1(x)[/tex]= ∛(4x-24)
and to do c just put in 8 where x is
∛(4(8)-24)= 2

Answer:
ur answer should be C. But I'm not really sure..
The table in which y is a linear function of x is; Choice C
Linear functionsAccording to the question;
We are required to identify in what table y is a linear function of x.The slope of a linear function is always constant.
Hence, By observing the table in Choice C;
Slope = (8-6)/(0-(-1)) = (10-8)/(1-0) = 2.
Hence, since slope of the function is constant, the required table is: Choice C.

Without calculating, predict whether the area of the rectangle will be greater or less than 25 square meters if the length is 5.25 meters.
Answer:
depends on the other side, so... maybe
Step-by-step explanation:
If you have a rectangle and you know one side is 5.25, then if the perpendicular side looks about the same length or longer, then the area of the rectangle is at least 25.
Imagine you have a rectangle with a known base of 5.25, then if the rectangle is at least as tall as it is wide, then the area is over 25. If the rectangle is very close to a square then the area should be near 25, and if the rectangle is visually shorter than it is wide then the area is less than 25

x^2-7x-34=10
Step-by-step explanation:
x2-7x-34-10=0
x2-7x-44=0
(x-11)(x+4)=0
x= 11 or x= -4
Answer:
x = 11 or x = -4
Step-by-step explanation:
x^2 - 7x - 44 = 0
-11 + 4 = -7, -11 × 4 = -44
(x -11)(x + 4) = 0 or (x + 4)(x - 11) = 0 Both are same way: O
x = 11 or x = -4 would be the answer : )
