Please solve this problem.

x=number of oranges.

y=number of bananas.

$5

we can suggest this system of equations:

x+y=12

0.5x+0.25y=5

We can solve this system of equations by substitution method.

x=12-y

0.5(12-y)+0.25y=5

6-0.5y+0.25y=5

-0.25y=5-6

-0.25y=-1

y=-1 /- 0.25=4

x=12-y

x=12-4=8

Tanya bought 8 oranges and 4 bananas.

8 apples 4 orange

Step-by-step explanation:

the 4th choice is the correct one

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
