Answer:

y=-4x-33

Step-by-step explanation:

Since the equation is parallel it will have the same slope which is -4

Now just plug in the points into the equation y=-4x+n

Plug them in and you get -5=-4(-7)+n

Then solve which will get you n=-33

Therefore the equation is y=-4x-33

Answer:

$42 per day

Step-by-step explanation:

Michael works 6 days every month

His grandfather pays him the same amount each day.

Michael earned $252

e = $252

Amount Michael earns per day = Total amount earned in a month / number of days worked for in a month

= $252 / 6 days

= $42 per day

It appears that the rate of change for this sequence is +3 because since t(1) = 11 and t(3) = 17, it would make sense that t(2) = 14.

From there you can use a calculator and start from 17 and keep adding 3 until you notice a number that doesn't belong in the sequence.

Step-by-step explanation:

Answer:

3 pencils per jar

hope it helps you

The number of pencils in each jar will be 3.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that there are 24 pencils in 8 jars. The number of pencils in each jar will be calculated as,

Number = Number of pencils / Number of the jars

Number = 24 / 8

Number = 3 Pencils

Hence, there will be 3 pencils in each jar.

38 minutes each day

Step-by-step explanation:

Answer:

38 minutes per day

Step-by-step explanation:

The information given says that Jace practices 798 minutes in 3 WEEKS and we need to convert that to days. There are 7 days in a week so multiply

7 x 3 = 21

Now you have to divide the minutes by 21.

798 ÷ 21 = 38

Jace practices piano for 38 minutes every day.

Sum of first n terms of two AP's are in the ratio (3n + 8) : (7n + 15).

the ratio of their 12th terms​

Let the first terms and common differences of the two APs be a , d & a' , d'.

We know that,

Sum of first n terms of an AP (Sn) = n/2 * [ 2a + (n - 1)d ]

So,

⟹ n/2 * [ 2a + (n - 1)d ] : n/2 * [ 2a' + (n - 1)d' ] = 3n + 8 : 7n + 15

⟹ 2a + (n - 1)d : 2a' + (n - 1)d' = 3n + 8 : 7n + 15

Multiply numerator and denominator by 1/2 in LHS

⟹ a + (n - 1)/2 * d : a' + (n - 1)/2 * d' = 3n + 8 : 7n + 15

Now,

3n + 8 : 7n + 15 is the ratio of nth terms of the two APs.

We have to find the ratio of 12th terms.

We know that,

nth term of an AP (aₙ) = a + (n - 1)d

⟹ a₁₂ = a + (12 - 1)d

⟹ a₁₂ = a + 11d

So,

⟹ a + (n - 1)/2 * d = a + 11d

⟹ n - 1/2 = 11

⟹ n - 1 = 22

⟹ n = 23

Hence, we have to substitute n as 23 to find the ratio of their 12th terms.

⟹ a + 11d : a' + 11d' = 3(23) + 8 : 7(23) + 15

⟹ a + 11d : a' + 11d' = 77 : 176

⟹ a + 11d : a' + 11d' = 7 : 16

∴ The ratio of the 12th terms of the two APs is 7 : 16.

I hope it will help you.
