Answer:
Step-by-step explanation:
Taking any two points, say (0,-3) and (2,-4), we can find the slope using the formula 
, which gives
.
From the graph, we can see the y-intercept is 
, so the equation of the line is .
0.8(5x + 15) = 2.6 - x + 3 Use the Distributive Property
4x + 12 = 2.6 - x + 3 Combine like terms (2.6 and 3)
4x + 12 = 5.6 - x Add x to both sides
5x + 12 = 5.6 Subtract 12 from both sides
5x = -6.4 Divide both sides by 5
x = -1.28
Child = $5.70
Adult = $9.80
- We can conclude that the amount of adult is double the amount of child tickets bought. (total of $556.60)
For this, you will need to divide the total amount by two and draw a tree chart with each of the numbers to get the seperation of the two. I would find out how many 9.80s or 5.70s go into $56.60 so you'll just have $500
Y⁴ + 12y² + 36
Now factorize the expression
y⁴ + 6y² + 6y² + 36
= y²(y² + 6) + 6(y² + 6)
= (y² + 6) (y² + 6)
<span>Now 6 is not the perfect square and according to rule, binomial can not be factored as the difference of two perfect squares.
</span>so multiply both.
(y² + 6)² is the answer.
