Answer:
b = 2
Step-by-step explanation:
4(3b+2)2 = 64
4×2=8
8(3b+2) = 64
Divide by 8 on both sides of equation.
3b+2 = 8 Subtract 2 from both sides of equation.
<u> -2 -2</u>
Divide by 3 on both sides of equation.
b = 2
Answer:
Priya got it right.
Step-by-step explanation:
I wouldn't have done it the way she did, but it's still correct. You can check with a calculator (if Khan Academy allows you to) or do it like this:
If f = 4, then f ÷ 0.25 should be 16.
4 ÷ 0.25 = 16
So, Priya got it right.
Answer:
B: 4 solutions
Step-by-step explanation:
Combining the two equations results in 2x² = 52, or x² = 26.
This equation has two solutions: x = ±√26.
As before, x² = 26. If we substitute 26 for x² in the 1st equation, we get:
26 - 4y² = 16, or 4y² = 10, or y = ±√5/2. Again: two solutions.
If we take x to be +√26, y could be ±√(5/2).
Check: is ( √26, √(5/2) ) a solution of the system?
Subbing these values into the first equation, we get:
26 - 4(5/2) = 16. Is this true?
Then 10 = 10. Yes.
Through three more checks, we find that this system has FOUR solutions.
It should be F=(C * 9/5) +32 I believe
The domain of the rational function in discuss as in the task content is the set of all real number values.
<h3>What is the domain of a rational expression?</h3>
The domain of a rational function or expression is the set of all real values of x, except for that/those which render the function or expression undefined as the case may be.
However, in this scenario, the denominator of the rational function is constant and hence all X-values render the expression defined.
Ultimately, the domain of the expression is the set of all real number values of x.
