If –3(y - 1) = 9, find the value of 1/2y

Answer:

y = -5/2 x - 2

Step-by-step explanation:

The standard form of equation of a line is expressed as;

y = mx+c

m is the slope

c is the yintercept

Given

m = -5/2

c = -2

Substotute into the exoression above

y = -5/2 x + (-2)

y = -5/2 x - 2

Hence the equation in standard form is y = -5/2 x - 2

No

Step-by-step explanation:

MONICA:

Principal, p = 300

Simple interest, r = 4.3% = 0.043

CALL:

Principal, p = 400

Simple interest, r = 4.2% = 0.042

Amount, A received by each after one year :

Recall:

A = p(1 + rt) ; time, t = 1 year

MONICA:

A = 300(1 + 0.043(1))

A = 312.9

CALL = 400(1 + 0.042(1))

A = 416.8

Monica is incorrect, this is because amount earned is not only dependent on the interest rate but also the number of period and the initial or principal amount deposited.

Answer:

$7.34

Step-by-step explanation:

To compute sum of dollars that are not whole numbers. Using the sum of$5.89 and$1.45 as an illustration :

$5.89 + $1.45

Taking the whole numbers first:

$5 + $1 = $6

Take the sum of the decimals :

$0.89 + $0.45 = $1.34

Sum initial whole + whole of sum of decimal

$6 + $1 = $7

Remaining decimal : $1.34 - $1 = $0.34

$7 + $0.34 = $7.34

Opposing angles are equal to each other. So, to solve this, use reverse order of operations.

63 + 21 = 84

84 ÷ 3 = 28

So x = 28

Henry can expect to roll a 4 about 20 times if he rolls a fair number cube 120 times.

It is a branch of mathematics that deals with the occurrence of a random event.

The probability of rolling a 4 on any given roll is 1/6.

The expected number of times that Henry can roll a 4 is equal to the probability of rolling a 4 on a single roll multiplied by the number of rolls.

Expected number of times to roll a 4 = Probability of rolling a 4 on a single roll × Number of rolls

Expected number of times to roll a 4 = (1/6) × 120

Expected number of times to roll a 4 = 20

Therefore, Henry can expect to roll a 4 about 20 times if he rolls a fair number cube 120 times.

Answer: The giraffe is 1.5 times tall as the zookeeper.

Step-by-step explanation:

Given: Height of Giraffe =  [tex]9\dfrac38\ feet =\dfrac{72+3}{8}\ feet =\dfrac{75}{8}\ feet[/tex]

Height of zookeeper=  [tex]6\dfrac14\ feet =\dfrac{24+1}{4}\ feet =\dfrac{25}{4}\ feet[/tex]

Let n = number of times the giraffe is tall as the zookeeper.

[tex]n=\dfrac{\dfrac{75}{8}}{\dfrac{25}{4}}=\dfrac{75\times4}{25\times8} = 1.5[/tex]

Hence, the giraffe is 1.5 times tall as the zookeeper.
