Answer: y = -1

Step-by-step explanation:

Assuming "distance from the origin is one unit" means distance on the x axis, a vertical straight line having an x-intercept of -1 would satisfy thede requirements. y = -1 isn't much of an equation, but it goes through (-1,2) and is 1 unit (-1) from the origin.

Answer:

y = -1/2x + 3/2

Step-by-step explanation:

(2-0)/(-1-0) = -1/2

2 = -1/2(-1) + b

2 = 1/2 + b

b = 3/2

A piece of toast came out of the toaster very overcooked.

Nikitich [7]

Answer:

It is a chemical change ⇒ 1st answer

Step-by-step explanation:

* Lets explain the statements to solve the problem

- A chemical change occurs when a new substance is formed through

a chemical reaction

- Ex: cooking an egg

- Change of reaction is the rate of reaction it can be decreases or

increasing

- A phase change is a change from one state to another without a

change in chemical composition

- Ex: Condensation: the substance changes from a gas to a liquid

- A physical change, such as a state change or dissolving, but does

not create a new substance

- Ex: Breaking a glass

* Lets solve the problem

- A piece of toast came out of the toaster very overcooked.

∵ It is like the cooking an egg

∴ It is a chemical change

Leanne multiplied 8 x 4.3 and got 32.24. Is Leanne correct?Use an area model to explain your answer

dlinn [17]

Answer:

No, not correct.

Step-by-step explanation:

Note that 8 * 4.3 can be broken up as follows:

8 * (4 + 0.3)

and that 4*8 =32, and that 0.3(8) = 2.4 (not 0.24).

Then 8 * (4 + 0.3) becomes 32 + 2.4 = 34.4

The URS construction company has submitted two bids, one to build a large hotel in London and the other to build a commercial o

topjm [15]

Answer: Our required probability is 0.55.

Step-by-step explanation:

Since we have given that

Probability that chance of winning the hotel bid = 40%

Probability that no chance of winning the hotel bid = 100-40=60%

Probability that chance of winning the office building bid = 25%

Probability that no chance of winning the office building bid = 100-25 = 75%

So, Probability that the company will win at least one contract is given by

$0.4\times 0.75+0.6\times 0.25+0.4\times 0.25\\\\=0.55$

Hence, our required probability is 0.55.
