Answer:
3.25=x
Step-by-step explanation:
start with -5=4x+8
subtract 8 from each side to get:
-13=4x
divide each side by 4 to get your answer:
-3.25=x-
<em>9/-1</em>
<em />
Because you do what’s in parentheses first which is (6+3)
You get the answer 9
Then you do 4-5 which will lead to going into negative numbers and the answer will be -1
So 9/-1 or Nine divided by negative one
Answer:
Step-by-step explanation:
When you write
-1
y = sin x, the "-1" is not an exponent, but rather an indication of "inverse function."
-1
y = sin x can also be written as y = arcsin x.
No exponentiation here, and no division here.
Answer:
a) true
Step-by-step explanation:
The bottom-line numbers from synthetic division <em>alternate signs</em>, indicating that -2 is a lower bound. The given statement is true.
__
If the signs were all positive, it would indicate the proposed zero is an <em>upper bound</em>.
__
A graph shows all real zeros are greater than -2.
Since we are finding the inverse you switch the variable. So it is now x=7y+2 and now you solve for y. You would get x-2/7 = y for the inverse
