Justin and his children went into a grocery store and he bought $18 worth of bananas and mangos. Each banana costs $0.60 and eac
Igoryamba

Answer:

x=10 and y= 8.

Step-by-step explanation:

Given that the cost of 1 banana = $0.60

Cost of 1 mango = $1.50.

Total cost= $ 18  

Here, x be the number of bananas and y be the numbers of mangos,

As the number of bananas is 2 more than the number of mangos,

So, x=y+2

\Rightarrow y=x-2 \cdots(i)

Cost of x bananas =\$ 0.60 \times x

Cost of y mangos =\$ 1.50 \times y

Total cost = 0.6x+1.5y

\Rightarrow 18 = 0.6x+1.5y\\\\\Rightarrow 1.5y=18-0.6x\\\\\Rightarrow y= 12 - 0.4 x \cdots(ii).

Solving both the equations (i) as well as (ii), graphically as shown in the figure by plotting both the graphs.

Both the graphs intersect at the point (10,8) as shown in the graph.

So, the solution of both the equations is, (x,y)=(10,8). i.e

The number of bananas = x= 10 and

the number of mangos = y = 8.

Which of the following ordered pairs represents a solution to the linear inequality y<6x-4? A. (0,3) B.(0,11) C. (0,-5) D.(0,
son4ous [18]

Answer:

<u>Option C. (0,-5)</u>

Step-by-step explanation:

See the attached figure.

As shown the shaded area represents the solution of the given inequality:

y < 6x - 4

The given options are the points:

A. (0,3) B.(0,11) C. (0,-5) D.(0,4)

Comparing the given points to the graph.

So, the point that will lie at the shaded area represent  solution to the linear inequality.

So, point (0,-5) is a solution to the linear inequality.

The answer is <u>option C. (0,-5)</u>

Note: the line y = 6x-4 is graphed using the table on the graph.
