Answer:
26 candy bars and 12 sodas
Step-by-step explanation:
This problem can be solved by a simple system of equations
I am going to call x the number of candy bars that Sally bought and y the number of sodas that Sally bought.
The fact that she bought 38 itens means the x + y = 38.
She spent $50.38. The value she spent is the sum of the number of candy bars multplied by the value of the candy bar and the number of sodas multiplied by value of a soda. So 1.25x + 1.49y = 50.38
So we have to solve the following system:
1)x + y = 38
2)1.25x + 1.49y = 50.38
From 1), we have that x = 38 - y. I am going to replace it in 2)
1.25(38-y) + 1.49y = 50.38
-1.25y + 1.49y = 50.38 - 47.5
0.24y = 2.88
y = 12.
Sally bought 12 sodas.
In 1: x = 38-y = 38-12 = 26
Sally bourght 26 candy bars

Answer:
It is a solution
Step-by-step explanation:
y = -4x - 8
Let x = -9 and y = 28
Substitute these values in
28 = -4(-9) -8
28 = 36 -8
28 =28
This is true so it is a solution
Answer:
17
Step-by-step explanation:
The quadratic function f (x) has a turning point at (5.-8). If 8(x)= f(x+7)-3. then at which of the following ... If f(x) is an odd. one-to-one function with f (5) = -2 then which point must lie on the graph of its ... Solve the equation f(x) = g(x) for all values of x. ... (3) (-4.10). 1. 2.64x+4 +y2-10y+25 =-12+4+25. (x+2)(x+2) +ly-sly-5)= 17.
