Neil is going to make concrete. He is going to use 180 kg of cement 375 kg of sand 1080 kg of stone.

Cement, sand and stone are sold in bags, shown in the table.

Neil already has 15 bags of cement, 22 bags of sand and 18 bags of stone.

How much cement does Neil have?

Give your answer in kg.

Please answer.

375kg?

Step-by-step explanation:

Because 1 bag has 25kg of cement so 15 bags should have 25×15

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
