An Expression Is Written In The Box.x+x-4What Is The Value Of This Expression When X = -6?0 -460 -35O

Answers

Answer 1

Answer:

the solution to that is 26.

Answer 2

Answer:

26

Step-by-step explanation:

Substitute x = - 6 into the expression

x² + x - 4

= (- 6)² + (- 6) - 4

= 36 - 6 - 4

= 30 - 4

= 26

Answer:

down here. I dont expect you to copy paste

Step-by-step explanation:

Arithmetic sequence: An arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k.

Arithmetic series : An arithmetic series is the sum of a sequence in which each term is computed from the previous one by adding (or subtracting) a constant

Difference: A sequence is defined as an arrangement of numbers in a particular order. On the other hand, a series is defined as the sum of the elements of a sequence.

How to use them : maybe

Geometric Sequence : A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.

Geometric series : In mathematics, a geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms.

Difference: A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.In mathematics, a geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms.

How to use: maybe

Arithmetic and geometric difference: The main difference between arithmetic and geometric sequence is that arithmetic sequence is a sequence where the difference between two consecutive terms is constant while a geometric sequence is a sequence where the ratio between two consecutive terms is constant.

Average rate of change : To find the average rate of change, we divide the change in the output value by the change in the input value.

Sigma notation :Often mathematical formulae require the addition of many variables Summation or sigma notation is a convenient and simple form of shorthand used to give a concise expression for a sum of the values of a variable.

Graph: A continuous function allows the x-values to be ANY points in the interval, including fractions, decimals, and irrational values. A discrete function allows the x-values to be only certain points in the interval, usually only integers or whole numbers.

Answers

Complete Question

Veronikas four test scores are 59, 80, 95, 88 and 93 if the outlier of 59 is removed what is the mean absolute deviation of the remaining four test scores?

Answer:

5

Step-by-step explanation:

We have the four test scores

80, 95, 88 and 93

Step 1

We find the mean of the 4 test scores

= 80 + 95 + 88 + 93/4

= 356 / 4

89

Step 2

The formula for Mean Absolute Deviation =

Summation( x - Mean)/n

Hence,

|(80 - 89 )+( 95 - 89) + (88 - 89) + (93 - 89)|/5

= 9 + 6 +1 + 4/4

= 20/4

= 5

The population of Dawn land is changing exponentially. This change is modeled by the function f(x) = 60,000(1.01)x . Interpret the function to describe how the population changes. Explain how you know.

Answers

Answer:

The function has an initial population size of 60,000 which increase at a rate of 1%

Step-by-step explanation:

Given the expression :

f(x) = 60,000(1.01)^x

Since 1.01 > 1 (exponential

The general form of an Exponential growth function.

y = p(1 + r)^x

p = 60000 = initial population

1 + r = 1.01 ; where r = growth rate

r = 1.01 - 1 ; r = 0.01 =

r = 0.01 * 100% = 1% growth rate

Please help with systems of equations need super urgent
*Check the pic*

Answers

Answer:

y = ±5

x = ±6

Step-by-step explanation:

Here we have the system:

x^2 + y^2 = 61

x^2 - y^2 = 11

Notice that we have both variables squared, then we can define:

x^2 = X

y^2 = Y

And write our system as:

X + Y = 61

X - Y  = 11

To solve this, the first step is to isolate one of the variables in one of the equations, i will isolate X in the second equation:

X = 11 + Y

Now we can replace this in the other equation to get:

(11 + Y) + Y  = 61

Now we can solve this for Y

11 + 2*Y = 61

2*Y = 61 - 11 = 50

Y = 50/2 = 25

Y = 25

And remember that Y = y^2

then:

y^2 = 25

y = √25 = ±5

And using the equation: X = 11 + Y

X = 11 + 25 = 36

X = x^2 = √36 = ±6
