9. Write an expression to represent the total number of cupcakes and cookies Darren sells in 2 days. 10. Evaluate the expression to find the total number of cupcakes and cookies Darren sells in 2 days. Darren owns a bakery. Each day, he bakes 48 cupcakes. He gives away 4 and sells the rest. Each day, he also bakes 36 cookies. He gives away 6 and sells the rest.

a) The expression for the total number of

= 2(x + y)

= 2x + 2y

b) Evaluate the expression to find the total number of cupcakes and cookies Darren sells in 2 days.

160

Step-by-step explanation:

a) Write an expression to represent the total number of cupcakes and cookies Darren sells in 2 days.

Let the number of cupcakes Darren sells in a day = x

The number of cookies Darren sells in a day = y

The expression for the total number of

= 2(x + y)

= 2x + 2y

Darren owns a bakery. Each day, he bakes 48 cupcakes. He gives away 4 and sells the rest.

Hence, The amount of cupcakes Darren sells = 48 - 4

x = 44 cup cakes

Each day, he also bakes 36 cookies. He gives away 6 and sells the rest.

The amount of cookies Darren sells

= 36 - 6

y = 30 cookies

b) Evaluate the expression to find the total number of cupcakes and cookies Darren sells in 2 days.

The total number of cupcakes and cookies Darren sells in 2 days is

= 2(44 + 36)

= 2(44) + 2(36)

= 88 + 72

= 160

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
