Answer:
A function is said to be an even function if its graph is symmetric with respect to the y-axis. For example, the function f graphed below is an even function. Verify this for yourself by dragging the point on the x-axis from right to left. Notice that the graph remains unchanged after a reflection across the y-axis!

Answer:
6 eggs
Step-by-step explanation:
given
one third (i.e 1/3 ) ---> equivalent to 2 eggs
total number of eggs
= three-thirds
= 3 x (1/3) -----------> equivalent to 3 x 2 eggs = 6 eggs
Answer: i. Cost of adult ticket = $ 30
ii. Cost of child ticket = $20
Step-by-step explanation:
Define variables:
Let x= cost of 1 adult tickets , y= cost of 1 child tickets.
Form linear equations:
5x+3y = 210 (i)
2x+5y= 160 (ii)
Multiply (i) by 2 and (ii) by 5
10x +6y = 420 (iii)
10x+25y = 800 (iv)
Eliminate (iii) from (iv)
19y = 380
⇒ y= 20
Put this in (i)
Hence, Cost of adult ticket = $ 30 and Cost of child ticket = $20
Let's make the inequality.
The sum of twice a number and 2. We're adding and multiply. X will be the number. 2x+2
Is greater than 4. We'll be using the greater than sign. >4; let's put it together.
2x+2>4; let's solve. First by subtracting two on both sides. 2x>2; let's divide by 2. x>1
So, the inequality is 2x+2>4. To solve it, it is x>1.
