Answer: (2,2)
Step-by-step explanation:
The solution of the system of equations is the intersection point, or the point where both lines meet. Looking at the graph, we see that the blue and red line meet at (2,2). That means the solution is (2,2).
We can also solve this algebraically. Since we are given that y=x, we can plug that into the equation and solve.
y+2y=6 [combine like terms]
3y=6 [divide both sides by 3]
y=2
Since we are told that y=x, we know that x is also 2. This tells us that the solution is also (2,2).

Of the 520 students participating in a chess tournament, 35% were male. How many females were in the tournament?
Answer:
182
Step-by-step explanation:
take 520 and multiply by 0.35
The number of female students participated in a chess tournament is 338.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, 520 students participating in a chess tournament, 35% were male.
Number of male students = 35% of 520
35/100 ×520
= 0.35×520
= 182
So, the number of female students
= 520-182
= 338
Therefore, the number of female students participated in a chess tournament is 338.

Vijay’s wages were increased from £115 per week to £130 per week.
What was the percentage increase to one decimal place?
Answer:
13%
Step-by-step explanation:
Increase = (New Number - Old Number) / Old Number
(130 - 115) / 115
15/115 = 0.130434783.
0.130434783 * 100 (to get the percentage) = 13.0%
what is the value of f (4) if it is defined by f (x) =2x+3
Answer:
11
Step-by-step explanation:
Substitute 4 for x
2(4) +3
Answer:
11
Step-by-step explanation:
F(x) = 2x+3 is just a function, so if you replace one of the "x" with 4 you have to replace the other one so it just becomes
F(4) = 2(4) + 3 then you do 2(4) = 8 then add 3 to it and it gets you 11.

Which pair of complex numbers has a real-number product?
* (1 + 3))(61)
* (1 + 3) (2-3)
* (1 + 3) (1-3)
* (1 + 3) (31)
Answer:
(1 + 3i)(1 - 3i)
Step-by-step explanation:
The product of a complex number and its conjugate produce a real number.
given a ± bi the conjugate is a ∓ bi ← where a and b are real, then
(a + bi)(a - bi)
= a² - b² ← a real number
The only pair of conjugate complex numbers in the list is
(1 + 3i)(1 - 3i)
The pair of complex numbers that has a real-number product is:
(1 + 3) (1-3) = -8
Option C is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
For a pair of complex numbers to have a real-number product, their imaginary parts must cancel out when the product is expanded.
Let's expand each pair of complex numbers and see which one has a
real-number product:
(1 + 3) x (61) = 61 + 183i
This product has a non-zero imaginary part, so it is not a real number.
(1 + 3) x (2-3) = -5 + 5i
This product has a non-zero imaginary part, so it is not a real number.
(1 + 3) x (1-3) = -8
This product has no imaginary part, so it is a real number.
(1 + 3) x (31) = 124 + 124i
This product has a non-zero imaginary part, so it is not a real number.
Therefore,
The pair of complex numbers that has a real-number product is:
(1 + 3) (1-3) = -8
