HELP PLEASE!!!!!!!!!!!!!!!!!!!!!

Mathematics
1 answer:
rewona [7]3 years ago
7 0

Answer:

Considerations:

$y=-(x) \left \{ {{\text{if } x0} \atop {{\text{if } x> 0\text{ then }y

$y=x\left \{ {{\text{if } x0}} \right. $

Also,

$-\frac{a}{b}=\frac{-a}{b}=\frac{a}{-b}, b\neq0         $

A positive number divided by a positive number results in a positive quotient, and its opposite is always negative.

The fraction $\frac{5}{-12} $  can be described as a positive number divided by a negative number, which always result in a negative quotient.

The fractions have same value, so Liam is correct.

I need help! can anybody help?​
Alexandra [31]

Answer:

i, m, and then k (use my method to do the other one)

Step-by-step explanation:

The longer than angle the longer the side tht is opposite to it... so for example, each angle and its opposite correspond to each other.. so K it is side K and so on...

first u should find the missing angles, for A, we know the angles 118 and 28 and a triangle is a total of 180 degrees, so add 118 and 28, which will give u 146, now subtract tht from 180 and u get 34, so the missing angle M is 34, now we can see which angles correspond to which side:

K = k

M = m

L = l

so the shortest will be l, then it will be m, and then it will be k

The graph below shows the number of paintballs a machine launches, y, in x seconds:
IrinaVladis [17]

Answer:

The expression that can be used to calculate the rate per second at which the machine launches the balls is fraction 20 over 4.

Step-by-step explanation:

The x-axis label is Time in seconds, and the x-axis values are from 0 to 20 in increments of 4 for each grid line.

And the y-axis label is Number of Balls and the y-axis values from 0 to 100 in increments of 20 for each grid line.

If the ordered pairs (4,20) and (8,40) are on the graph, then the slope of the line will be represented by  

M = \frac{40 - 20}{8 - 4} = \frac{20}{4}

Therefore, the expression that can be used to calculate the rate per second at which the machine launches the balls is fraction 20 over 4. (Answer)

Piper opened a savings account with $1400 that pays no interest. She deposits an
erik [133]

Answer:

$3700

Step-by-step explanation:

Given that:

Initial amount = $1400

Amount deposited per week = 50

Amount after 47 weeks =?

Using the Arithmetic Progression relation :

Tn = A + (n - 1)d

Weekly deposit = d = 50

A = initial / first deposit = 1400

n = number of deposits

T47 = 1400 + (47 - 1)50

T47 = 1400 + (46)*50

T47 = 1400 + 2300

T47 = 3700

Help me please I literally don’t understand any of this. I know it’s easy too.
Ber [7]

Holigina, this is the solution:

Let's recall that √x = x ^(1/2)

Therefore,

√x√x = x ^(1/2 + 1/2) = x^1 (We sum the exponents of the same base)

The correct answer is C. 1

Marilyn is playing a game where she draws a slip of paper with the words "Rock, Paper, Scissors" written on each slip from a hat
marysya [2.9K]

Answer:

1/6

Step-by-step explanation:

In a game of "Rock, Paper, Scissors", there are three possibilities. The probability that Marilyn will get Paper is given as

1/3

In a coin flip, the probability that it will land on tails is

1/2

Therefore, the probability that she will win if she predicts "Paper" and calls Tails is the product of the individual probabilities:

1/3 * 1/2 = 1/6
