For this case we have the following equation:
From here, we must clear the value of x.
For this, we follow the following steps:
1) We raise both members of the equation to the square:
2) We pass the number 1 subtracting:
3) We pass number 8 dividing
:
We observe that the given equation can be evaluated for the solution obtained.
Therefore, the solution is valid.
Answer:
C) x = 3, solution is not extraneous
197 you take the 595 and divide it by 3 and you will get 197
Answer:
2/4
Step-by-step explanation:
Using a graph, you would start at (-1,2). Next you would move up twice. Then you would move 4 lines to the right. You'll land on (3,4)
Step-by-step explanation:
increase in Tyler's pay = 16 - 14 = 2
% increase in Tyler's pay = 2/14 × 100 = 14.3%
Increase in Allies' pay = 18 - 16 = 2
% increase in Allies'pay = 2/16 × 100 = 12.5%
hence the right option is:
3).The percent increase Tyler's pay rate is greater than Allies'.
Increase in Martin's pay = 15.00 - 13.50 = 1.50
% increase in Martin's pay = 1.50/13.50 = 11.1%
Answer:
A
Step-by-step explanation:
y = -9 ------(1)
9x -4y = -9 -------(2)
substitute (1) into (2)
9x - 4 (-9) = -9
9x = - 45
x = -5
there you go, x = -5 and y = -9
so. (-5 , -9 )
