X, y - the numbers
The product is 18.
The quotient is 2.
Substitute 2y for x in the 1st equation:
The numbers are
6 and 3 or
-6 and -3.
2x-y=7
y=2x+3
Substitute (2x+3) in for y in the first equation
2x-(2x+3)=7
2x-2x-3=7
-3=7
Becuase -3 does not equal 7 the answer is no solution
Answer:
21.758
Step-by-step explanation:
If you draw the triangle out, you find that cos 41 = x/28.83, when x is equal to the side opposite the 49 angle
Simplify this into 28.83 cos 41, and plug it into the calculator and you get
21.75827.
We have been given a graph that models the cost of a cheese pizza with extra toppings at two different restaurants. Now using the graph, we have to find about how many pizza toppings must be added to make the cost of the pizzas from both restaurants equal.
To find that we just have to look at the intersection point of both graphs.
If you look carefully then you will find that both graph intersect at the point where x-coordinate is 5.
Hence final answer is 5 toppings.
