Answer:
34/40
Step-by-step explanation:
85/100 cross multiply x/40
100x/100=3400/100
x=3400/100
3400/100=34
x=34

Answer:
Step-by-step explanation:
You can start this in may ways but let's start by isolating one of the parenthesis:
x (x² - 5) = - (x - 3)
x³ - 5x = -x + 3 (here I multiplied x for what's inside the parenthesis and the "minus" signal by the other parenthesis which was (x - 3))
x³ - 5x + x = 3
x³ -4x = 3
x³ -4x -3 = 0 (now this right here is a "depressed cubic equation" and it's one of the toughest sit of all time, so good luck with that, you might wanna take a look at this:
ytb/watch?v=rNDy2ZFvG1E
or maybe I'm doing something wrong and it's simpler than that, but whaterver...)
and surely you'd know what the roots are
True. When the points are plotted on a graph and connected, they pass the vertical line test. No x value is the same.
Answer:
Step-by-step explanation:
To solve this exercise you need to remember the following:
→
Therefore, keeping the above on mind, you can solve for x as following:
Remember that, by definition: , then you have:
Subtract 6 from both sides of the equation.
Then the value of x is:
