Answer:
adult = £5
child = £2
Step-by-step explanation:
a = adult c = child
3a + 4c = 23
1a + 5c = 15
multiply second equation by 3 and rewrite
3a + 4c = 23
3a + 15c = 45
subtract
0 - 11c = - 22
-11c = -22
11c = 22
<em><u>c</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>£</u></em><em><u>2</u></em>
subsitute into one of the equations and solve for a
1a + 5c = 15
a + 5(2) = 15
a + 10 = 15
<em><u>a</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>£</u></em><em><u>5</u></em>
I'm not entirely positive about it but I think it might be N=CxP..
B. Because you take 91 and divide it by 7 to get 13 then multiply 11 by 13.
Answer:
![f(x)=x^{2}+1](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E%7B2%7D%2B1)
Step-by-step explanation:
we have
![g(x)=x^{2}](https://tex.z-dn.net/?f=g%28x%29%3Dx%5E%7B2%7D)
This is the equation of a vertical parabola open upward
The vertex is a minimum
The vertex is the point (0,0)
The graph of f(x) has the same shape as the graph of g(x), but is shifted up 1 unit
so
The vertex of the function f(x) is (0,1)
The rule of the translation of g(x) to f(x) is
(x,y) ----> (x,y+1)
therefore
The equation of f(x) is equal to
![f(x)=x^{2}+1](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E%7B2%7D%2B1)
