Solve the system by the substitution method.

Gemiola [76]

Answer:

(2,2)

Step-by-step explanation:

Given equations

x-3y=-4-------------------------------(1)

y=-3x+8.------------------------------(2)

Substitute 2 in 1. This means use the value of y in equation 1, to replace y

x-3(-3x+8)=-4------------------open brackets

x+9x-24=-4---------------------collect like terms

10x=-4+24

10x=20---------------------------divide by 10 both sides to get value of x

10x/10=20/10=2

x=2------------------------------use value of x in equation (2) to get value of y

y=-3x+8

y=-3(2)+8

y=-6+8=2

solutions

x=2, y=2

Sammy bought 15.3 Liters of milk. She poured the milk equally into 5 bottles. There was 0.35 liters of milk left over. Calculate

Zanzabum

Answer:

The capacity of milk in 1 bottle is 2.99 liters

Step-by-step explanation:

Let us solve the question

∵ Sammy bought 15.3 liters of milk

∵ She poured the milk equally into 5 bottles

∵ There were 0.35 liters of milk leftover

→ At first, subtract the leftover from the quantity she bought to

find the capacity of the five bottles

∴ The capacity of the 5 bottles = 15.3 - 0.35

∴ The capacity of the 5 bottles = 14.95 liters

→ To find the capacity of each bottle divide the total capacity by 5

∴ The capacity in one bottle = 14.95 ÷ 5

∴ The capacity in one bottle = 2.99 liters

∴ The capacity of milk in 1 bottle is 2.99 liters

How do you do this? Please give an example to #1 and explain thoroughly please. I have asked multiple times and gotten answers I

liberstina [14]

Answer:

y=2x

Step-by-step explanation:

y = kx is the format of the graph we are looking for (as told in the instructions) where k is the variable we are supposed to find (like y = x, y=2x, y=3x, etc)

Note that as x increases by 1, y increases by 2. We can see that by writing a table of the points of points that the line given intersects (picture below). We can see that by the values of the x-axis and the y-axis. Why does this happen? This is because y =2x for each value of x. We notice that in our table.

Therefore, the equation is y=2x. I hope this helps! If you still have questions, ask me in the comments!

Mr. Toshiro manages a company that supplies a variety of domestic and imported nuts to supermarkets. He received an order for 12

alexandr1967 [171]

Answer:

n = 120i + 310j + 60k

p = 29i + 18j + 21 k

Total cost = $10,320

Step-by-step explanation:

Let n and p represent the vectors for number of products and prices respectively.

Also, the coordinates i,j and k represent cashews, walnut and Brazil nut respectively.

The vector form of the total number of bags ordered and the cost are;

n = 120i + 310j + 60k

p = 29i + 18j + 21 k

We can obtain the total cost by obtaining the dot product of the two vectors.

Total cost = n.p = (120i + 310j + 60k).(29i + 18j + 21 k)

C = 120×29 + 310×18 + 60×21

C = $10,320
