Answer:
The solution is (2, 1).
All other ordered pairs do not work.
Step-by-step explanation:
-2x + 5y = 1
5x - 3y = 7
-10x + 25y = 5
10x - 6y = 14
19y = 19
y = 1
5x - 3(1) = 7
5x = 10
x = 2
(2, 1)
The solution is (2, 1).
All other ordered pairs do not work.
Answer:7
Step-by-step explanation:
This question is on the ukmt junior maths challenge which I'm doing now, out of the options given I got 7, because 2+4+6+5+(5×20)+(7×7)= 166, (then dividing that by the number of numbers to get the mean) so 166÷31= 5.354.....
Also the 3 has a recurring symbol above it
The 7 is times seven so uh yeah<3
Answer:
Option (C)
Step-by-step explanation:
Two statements given in the question are,
p: Memorial Day is in July
q: Parallel lines never intersect
We have to tell the represent the symbolic notation of the compound statement,
"Memorial Day is in July or parallel lines intersect"
Here word 'Or' is combining these statements.
We know word 'Or' means Disjunction which is denoted by the symbol (∨).
So the compound statement will be denoted by p ∨ q.
Option (C) will be the answer.
The choices are equivalent to the expression correct choices are A, C, and D.
The given expression is
x^3 /5
<h3>
What is the expression?</h3>
The expression consists of numbers and arithmetic operators. It does not contain equality or inequality symbols.
<h3>What is the power rule?</h3>
![a^{\frac{m}{n} =\sqrt[n]{a^m}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%20%3D%5Csqrt%5Bn%5D%7Ba%5Em%7D)
Therefore the above power rule implies that,
![x^{(\frac{3}{5}) }=\sqrt[5]{x^3}](https://tex.z-dn.net/?f=x%5E%7B%28%5Cfrac%7B3%7D%7B5%7D%29%20%7D%3D%5Csqrt%5B5%5D%7Bx%5E3%7D)
Also, we have the power rule
or it can be written as
![x^{\frac{3}{5} =(\sqrt[5]{x})^3](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B3%7D%7B5%7D%20%3D%28%5Csqrt%5B5%5D%7Bx%7D%29%5E3)
The correct choices are A, C, D.

Answer:
B. x = -8
Step-by-step explanation:
-4(2x + 3) = 2x + 6 - (8x + 2)
-8x -12 = 2x + 6 - 8x -2
(now, "-8" in both terms is cancelled):
-12 = 2x + 6 - 2
(leave 2x alone in second term):
-12 -6 +2 = 2x
-16 = 2x
-16/2 = x
-8 = x
