PLEASE HELP

Lemur [1.5K]

1. y=6

2. y=-12

Step-by-step explanation:

<u>1) If y varies inversely as x, and y=3 as x = -2, find y for the x value of -1.</u>

It is given that

y varies inversely as x

IT will be written as:

y∝1/x

Removing the proportionality symbol

y=k/x

Given

y=3 , x=-2

Putting the values

3=k/-2

k=3*-2 = -6

The equation will be:

y=-6/x

So,

When x=-1

$y=\frac{-6}{-1}\\y=6$

<u>2) If y varies directly as x, and y=15 as x=-3, find y for the x value of 4</u>

y is directly proportional to x

y∝x

y=kx

Given

y=15, x=-3

Putting the values

$y=kx\\15=-3k\\k=\frac{15}{-3}\\k=-5\\The\ equation\ will\ be:\\y=-3xNow,\\x=4\\y=-3(4)\\y=-12$

Hence,

1. y=6

2. y=-12

In 5 years kate will be twice as old as joey. right now kate is 11 years older then joey. right now how old is joey?

natima [27]

K = Kate's age nowJ = Joey's age nowK+5 = Kate's age in 5 yearsJ+5 = Joey's age in 5 years From the first sentenceK+5 = 2(J+5) From the second sentenceK=J+11 So our system of equations isK+5 = 2(J+5)K=J+11 The first equation is equivalent toK+5 = 2J+10or by rearranging termsK-2J=5 The second equation is equivalent toK-J=11 This gives us K-2J=5K-J=11 Using the elimination method, we need to multiply one of the equations by a factor such that we can eliminate one of the variables. This means we want one of the variables to have coefficients which are the same magnitude but opposite signs. We can do this by multiplying the 1st equation by -1. This give us -K+2J=-5 K - J = 11 Now add these two equations together, term by term. This gives usJ=6 So Joey is 6 years old now.

The spinner below is spun once.

madam [21]

The probability that the spinner will land on 5 or 7 if the spinner is spun once is 1/4

<h3>How to determine the probability that the spinner will land on 5 or 7 if the spinner is spun once?</h3>

The sample space of the spinner is

S = {1, 2, 3, 4, 5, 6, 7, 8}

So, the sample size is

Size = 8

On the spinner, we have

n(5) = 1

n(7) = 1

The probability that the spinner will land on 5 or 7 if the spinner is spun once is calculated as:

P = P(5) + P(6)

This gives

P = 1/8 + 1/8

Evaluate

P =2/8

Simplify

P = 1/4

Hence, the probability that the spinner will land on 5 or 7 if the spinner is spun once is 1/4
