An expression is a mat scentence but not a complet on.Example:2x3. Or a x 5. I hope I said it clearly for you.
Answer:
Yes.
Step-by-step explanation:
First, make a graph, or imagine one.
I'll be making an example graph that only goes up to 13 here.
Age - 10 11 12 13
Height
v
6ft
5ft
4ft
If we mark this graph with points, you will find that there is only 1 point on each age line!
Age - 10 11 12 13
Height
v
6ft *
5ft * *
4ft *
This means the answer is yes!
Answer:
18
Step-by-step explanation:
Plugging in 3 for n, we get:

Answer:
The answer is given below
Step-by-step explanation:
The equation of a quadratic function is given by:
Ax² + Bx + C where A, B and C are the coefficients of the quadratic equation. If the coefficient of x² (i.e A) is a negative value then the graph opens down, the value of C determines the y intercept.
The equation of a parabola with y-intercept greater than 3 and opens down can be given as -2x² -6x + 4. Since the coefficient of x² is negative it opens down and C = 4, it has a y intercept of 4 > 3
Let us assume a vertical stretch of 2, the new equation becomes:
2(-2x² -6x + 4)
-4x² - 12x + 8
To solve:
-4x² - 12x + 8 = 0
A = -4, B = -12 and C = 8
Using the quadratic formula:

In this pattern, 8+11= 8+11 + 77 (the previous answer) = 96
As you go to the next step in the pattern, you add the previous answer as well, so:
1+4=5
2+5= 2+5+5= 12
3+6= 3+6+12 = 21
4+7= 4+7+21 = 32
5+8= 5+8+32 = 45
6+9= 6+9+45 = 60
7+10= 7+10+60 = 77
So 8+11= 8+11+77 +96
I'm not sure how to write this mathematically as such, only in a logical way, but I hope it helps!
