what is the explicate formula for -5,-8,-11

Answers

Answer 1
Every term is three less than the previous term.

Since -5 is our first term, we can set that to a(1) so that we can express a recursive formula:
a(n+1) = a(n) - 3

a(2) = -8
a(3) = -11
a(4) = -14
a(5) = -17

Jalil and Victoria are each asked to solve the equation ax – c = bx + d for x. Jalil says it is not possible to isolate x because each x has a different unknown coefficient. Victoria believes there is a solution, and shows Jalil her work:

ax – c = bx + d
ax – bx = d + c
x (a – b) = d + c
x = x equals StartFraction d plus c Over a minus b EndFraction.

The three linear equations have y-intercepts of -3, 8 and 7 respectively. Yet, a function can have only

one y-intercept. Which of these is the y-intercept of this function? Explain how you made your choice.

Answers

Answer:

hello your question have some missing part attached below is the missing part

answer : y ( intercept )  = 8

Step-by-step explanation:

Having three linear equations with y-intercepts of -3, 8 and 7,

To determine The y-intercept of this function ;

x = 0 and x = 0  which comes in   -2 ≤ x < 3

f' - f(x) = x + 8 ,

therefore the y intercept in  f(0) = 0 + 8 = 8

The y-intercept of the line whose equation is x - y= 7 is 0-7 01 07​

Answer:

Y intercept is 7 here,

how do you change a rational number to a decimal? give an example

Answers

Answer:

If the rational number is a fraction (of course) divide it. For example, 1/2 can be divided as 1 divided by 2 which is 0.5.

If the number is an integer, you can simply just add .0 (point zero). For example, if the rational number is 12, the decimal version would be 12.0.

If the number is a fraction, you can divide the numerator by the denominator. For example, if the rational number is 1/10 (one tenth), just can divide one by zero to get 0.1 (zero point one).

find ten rational numbers between -2/5 and 1/2 (i need in a proper explaination please answer fasttt!!!​)

Answers

Answer:

-0.39, -0.38, -0.37, -0.36, -0.35, -0.34, -0.33, -0.32, -0.31, -0.3

Step-by-step explanation:

Rational numbers are basically any number that are not numbers with non-recurring decimals or non-terminating decimals.

-[tex]\frac{2}{5}[/tex] = -0.4

[tex]\frac{1}{2}[/tex] = 0.5

Thus, any number from -0.4 to 0.5 with decimals (if any), that will terminate and not stretch forever is rational. [tex]\frac{1}{3}[/tex] is not rational. Decimals that repeat are also rational. pi is not rational.

One number is three more than the second number. Twice the first is nine less than three times the second. What are the two numbers?

Answers

Answer:

16 and 13

Step-by-step explanation:

Let the second no is x

First no = x+3

Twice the first is nine less than three times the second.

We can write in the form of equation as follows :

2(x+2) = 3x-9

Solving brackets first

2x+4=3x-9

Taking like terms together

9+4=3x-2x

13=x

First no = x+3 = 13 + 3 = 16

So, first and second numbers are 16 and 13 respectively.

in JKL, if m<J is 7 less than m<L and m<K is 21 less than twice m<L, find the measure of each angle​

Answers

Answer:

Step-by-step explanation:

First you must know that the sum of angle in a triangle is 180degrees

In triangle JKL, <J+<K+<L = 180 ..... 1

If m<J is 7 less than m<L , then;

m<J = m<L -7 ..... 2

If m<K is 21 less than twice m<L then;

m<K = 2m<L - 21 ...... 3

Substitute 2 and 3 into 1;

from 1; m<J+m<K+m<L = 180

m<L - 7 + 2m<L - 21 + m<L = 180

4m<L - 28 = 180

4m<L = 180+28

4m<L = 208

m<L = 208/4

m<L = 52 degrees

Get m<J;

m<J = m<L -7

m<J = 52-7

m<J = 45 degrees

Get m<K;

m<K = 2m<L - 21

m<K = 2(52) - 21

m<K = 104 - 21

m<K = 83degrees

The Rodriguez family took 5.5 hours to gather information for their Schedule A. The itemized deductions saved them $4,095 in taxes. What was the mean savings per hour to fill out Schedule A tax form?

Answers

Answer:

The mean saving was $744.54 per hour to fill out Schedule A tax form.

Step-by-step explanation:

Given that:

Time taken by Rodriguez family = 5.5 hours

Amount saved in taxes = $4095

5.5 hours = $4095

The mean savings per hour can be calculated by dividing the total hours taken by the amount saved in taxes.

1 hour = [tex]\frac{4095}{5.5}\\[/tex]

1 hour = $744.54

Savings per hour = $744.54

Hence,

The mean saving was $744.54 per hour to fill out Schedule A tax form.
