Can anybody help me with this
lys-0071 [83]

Answer:

a, y =3/x

x = 0.5 => y = 3/0.5 = 6

x = 1 => y = 3/1 = 3

x = 2 => y = 3/2 = 1.5

x = 3 => y = 3/3 = 1

x = 4 => y = 3/4 = 0.75

b,

y = 3/x passes (0.5, 6) => A is correct

Hope this helps!

John’s father is 5 times older than John and John is twice as old as his sister Alice. In two years time, the sum of their ages
oksano4ka [1.4K]

Answer:

John’s age is 8 years

Step-by-step explanation:

Let

x -----> John’s father's age

y -----> John’s age

z -----> John’s sister's age

we know that

x=5y -----> equation A

y=2z

z=y/2 -----> equation B

(x+2)+(y+2)+(z+2)=58

x+y+z+6=58

x+y+z=52  -----> equation C

Substitute equation A and equation B in equation C and solve for y

5y+y+y/2=52

Multiply by 2 both sides to remove the fraction

10y+2y+y=104

13y=104

y=8

<em>Find the value of x</em>

x=5(8)=40

<em>Find the value of z</em>

z=8/2=4

therefore

John’s father's age is 40 years

John’s age is 8 years

John’s sister's age is 4 years

D= number of dollars
padilas [110]

<u>Unit rate 4:</u>

The table

d      n

4       1

8       2

16      4

<u>Unit rate 1/4:</u>

Table

d      n

1       4

4       16

16      64

and

The equation n=4d

<u>Unit rate 16:</u>

Equation:

d = 16n

Step-by-step explanation:

The unit in the unit rate is dollars per unit ounces which means that the unit rate calculated by

Unit\ rate = \frac{dollars}{ounces}

So,

The first option is the equation:

d = 16n\\\frac{d}{n} = 16

The unit rate is 16 dollars per ounce

The second option is the table:

d      n

1       4

4       16

16      64

We can take any pair of values of d and n from the table to calculate the unit rate

So taking

d = 1

n=4

Unit\ rate = \frac{d}{n}\\= \frac{1}{4}

The unit rate for table is: 1/4 dollars per ounces

Third option is the equation:

n = 4d

n = 4d

dividing both sides by n

\frac{n}{n} = \frac{4d}{n}\\1 = \frac{4d}{n}

dividing both sides by 4

\frac{1}{4} = \frac{4d}{4n}\\\frac{d}{n} = \frac{1}{4}

the unit rate is 1/4 dollars per ounce

Fourth option is the table:

d      n

4       1

8       2

16      4

We will take any pair of d and n to find the unit rate

So,

Taking

d = 4

n =1

Unit\ rate = \frac{d}{n} \\= \frac{4}{1}\\=4

The unit rate is 4 dollars per unit ounce.

You can use a graphing paper or a software to create a scatter plot. I used MS Excel to plot the points. You simply have to type the values and create a graph. The x-axis is the number of years and the y-axis is the savings account balance.
