Identify the equation of the graph

Answers

Answer 1

Answer:

This has a vertex at (1,-5) and otherwise looks like y=x^2; the two points one x unit away from the vertex are also 1 y unit away, the two points two away are 4 units higher, etc.

$y = (x- 1)^2 - 5$

That's in vertex form. We're not shown any choices; let's multiply this out.

$y = x^2 - 2x - 4$

Either one of those.

What is referred as the unitary method?

The unitary method is a process that determines the value of a single unit from value of multiple units, as well as the value of multiple units from of the value of a single unit.
It is a method for determining the value of a single unit by subtracting the value of multiple units and subtracting the value of different components from of the value of a single unit.

For the given question.

If 78 sit-ups is done in 2 minutes.

this can be written as;

2 minutes -------> 78 sit ups.

For 1 minutes, divide both side by 2.

1 minutes -------> 39 sit ups.

For 5 minutes, multiply both sides by 5.

5 minutes -------> 195 sit ups.

Thus, in 5 minutes 195 sit ups can be done.

What is the simplest form of the expression (–12.7y – 3.1x) + 5.9y – (4.2y + x)?

Answers

The simplest form of given expression is $-11y-4.1x$ .

What is an expression?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given expression

$(-12.7y-3.1x)+5.9y-(4.2y+x)$

= $-12.7y-3.1x+5.9y-4.2y-x$

Combine like terms

= $(-12.7y+5.9y-4.2y)+(-3.1x-x)$

= $-11y-4.1x$

The simplest form of given expression is $-11y-4.1x$ .

Rolling a number cube labeled 1-6 and tossing a nickel

Answers

OK.

If you predict a number between 1 and 6, and
also predict heads or tails, then roll and flip,
the probability that the roll and flip will all fall
exactly like you predicted is

(1/6) x (1/2) = 1/12 = (8 and 1/3) % .

Do you have a question to ask ?

Rolling a cube with 1-6 has 6 possibilities. Tossing a nickel only has 2, heads and tails. Hope I helped!!! :D
