explanation:
reason is simple! the equation is given as h(x) = 
and all the x-values are given in the table, so you just have to plug them into the calculator and sub-in the x-values given to you to get the answer
Answer: B (2,1)
You know what y is (x-1) so you substitute that for y in the other equation.
3x+ ((4)(x-1))=10
3x+4x-4=10
7x=14
x=2
Then put x=2 into y=x-1
y=2-1
y=1
Each of the toppings cost 2$
Tan(40)= x/20 => x= tan(40).20= 16,78
Ok done. Thank to me:>
