Answer:
Step-by-step explanation:
First I just made -2/5 into a decimal because I like to work with decimals better (which equals -.4)
Then I times everything separately in the parenthesis and got -8x+6
Next you move the 6 over to the left side of the equals sign which would make the equation be -6 = -8x
Lastly you divide the -8 from -6 and you get X = 3/4
The value of y when x= 2401 is -10
<h3>How to determine the value of x?</h3>
An inverse variation is represented as:
Where k is the proportionality constant
When y = -70, x = 49
So, we have:
Take the square root of 49
Multiply through by 7
k = -490
Substitute k = -490 in
When x =2401, we have
Evaluate the square root
Divide
y = -10
Hence, the value of y when x= 2401 is -10

Answer:
Function
Step-by-step explanation:
The reason it is a function is because its saying y=x. Then you just plug in the number(s) to get the function y=4.PLEASE MARK BRAINLIEST thank you!!!!!!!!!
Answer:
x<2 is your answer
Step-by-step explanation:
-2x+4>-4x+8
subtract each term by 8
-2x+4-8>-4x+8-8
add both side by 2x
-2x+2x-4>-4x+2x
-4>-2x
dividing both term by -2
-2x/-2<-4/-2
x<2
X = -2
3 x -2 = -6
-6 -2= -8
|-8| = 8
-2 + 1= -1
|-1|=1
