2.) 5x+7 = 17
1.) 85+ (-10) = 95
3.) -8(-2) - 7 = 14 – 5
Answer:
1.) 85+ (-10) = 95 is false.
2.) 5x+7 = 17 is false.
3.) -8(-2) - 7 = 14 – 5 is false.
Step-by-step explanation:
1. is false because since 85 ≠ 95, then 85 + ( - 10) = 95 is false.
2. is false because since 12 ≠ 17, then 5x + 7 = 17 is false.
3. is false because since -15 ≠ 14, then -8( - 2) - 7 = 14–5 is false.
A die is rolled twice. What is the probability rolling a 3 first, followed by rolling an even number? Leave your answer as a reduced fraction.
The probability of rolling a 3 first, then an even number, is 1/12.
What do we mean by probability?Probability is simply the likelihood of something occurring. When we are uncertain about the outcome of an event, we can discuss the probabilities of various outcomes—how likely they are. Statistics is the study of events governed by probability.So, in the given situation the first roll has no effect on the second roll because they are separate events.
Because they are independent, the probabilities of the two events can be multiplied.
The probability of getting a 3 is 1/6.The probability of getting an even number is 1/2 (2, 4, 6).Now, we will multiply the two probabilities as follows:
1/6 × 1/2 = 1/12Therefore, the probability of rolling a 3 first, followed by rolling an even number is 1/12.

2x−3y=−5 4x−4y=−4 Is (2,3)(2,3)left parenthesis, 2, comma, 3, right parenthesis a solution of the system?
(2,3) is a solution to the system of equations.
A collection of one or more linear equations containing the same variables is known as a system of linear equations (or linear system).
Consider the system of equations,
2x - 3y = - 5 --------(1)
4x - 4y = - 4 --------(2)
Multiplying equation (1) with 2.
4x - 6y = - 10
4x - 4y = - 4
Now, subtracting the above equations:
4x - 6y - ( 4x - 4y) = - 10 + 4
4x - 6y - 4x + 4y = - 6
- 2y = - 6
2y = 6
y = 3
Then,
4x - 4y = - 4
4x - 4 × 3 = - 4
4x - 12 = - 4
Adding 12 on both sides of the equation,
4x - 12 + 12 = - 4 + 12
4x = 8
x = ( 8/4 )
x = 2
Therefore, (x, y) = ( 2, 3) is a solution to the system of equations.

explain how you would round 25.691 to the greatest place
Answer:
In order to round 25.691 to the greatest place or the nearest whole number, first start at the last digit behind the decimal, in the case, being the 1. When it comes to things like this, if the digit is 4&under meaning its the number 4,3,2,1 or 0. If it is 5&up, that means it could be 5-9, making the digit go up (but if its 2, then the digit just goes away, you wont have to worry about that one specific number).
Next step is to round the 9 which makes the 6 go up one digit (meaning it turns into a 7). Now, when you round the seven, it will make the whole number go up one digit, but if you want to round that as well, to start, it's first rounding equaled up to 26. If you're rounding it to a whole tens number, it would be 30. I hope that this helps you understand this subject or topic much better! :3

Suppose you go shopping for a new futon bed for your room. The model you really like happens to be on sale for $525. It's original price is $700. What percent of the original price will you save if you purchase it?
Round your percentage to one decimal place.
Do not include
%
sign with your answer.
25 percent of the original price was saved during the purchase of the futon bed
The percent of the original price that is saved can be calculated as follows
The original price is $700
The new price is $525
The first step is to calculate the percentage change
= 700-525
= 175
Therefore the percent saved can be calculated as follows
= 175/700 × 100
= 0.25 × 100
= 25
Hence 25 percent of the original price was saved

What are the solutions to the system of equations?
{y=2x2−5x−7y=2x+2
The solutions to the system of equations are (x₁, y₁) = (9 / 2, 11) and (x₂, y₂) = (- 1, 0).
How to resolve a system of equation by algebra methods
Herein we find a system formed by one linear equation and one nonlinear equation (quadratic equation). First, we equalize the two equations to eliminate the variable y:
2 · x² - 5 · x - 7 = 2 · x + 2
2 · x² - 7 · x - 9 = 0
2 · [x² - (7 / 2) · x - 9 / 2] = 0
2 · (x - 9 / 2) · (x + 1)
There are two solutions to x: x₁ = 9 / 2, x₂ = - 1. And the solutions for y are:
x₁ = 9 / 2y₁ = 2 · (9 / 2) + 2
y₁ = 11
x₂ = - 1y₂ = 2 · (- 1) + 2
y₂ = 0
Then, the solutions to the system of equations are (x₁, y₁) = (9 / 2, 11) and (x₂, y₂) = (- 1, 0).

Check the picture below.
Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease. y=45(0.974)^x
Given function y =45(0.974)ˣ is a function of exponential decay and percentage rate of decrease is 2.6%.
What is an exponential function?The exponential function is an function f(x) = a(b)ˣ
a = initial amount when x= 0
b= base that is multiplied and it is greater than 0
And x is the variable in the exponent
When b> 1 , the values of this function goes up and up and then this function shows exponential growth.
When 0< b< 1, the values of this function becomes smaller as x increases then this function shows exponential decay.
And r is the percentage rate of change where b =r +1
Given function is y = f(x) = 45(0.974)ˣ
When we compare it with standard function f(x) = a(b)ˣ
we get a = 45 and b =0.974
As b is between 0 and 1 in this case, therefore this function is exponential decay.
b =r+ 1
therefore r = b-1 = 0.974-1 = -0.026
converting 0.026 to percentage we get -0.026*100= -2.6% ( negative sign shows decrease)
Therefore, we can say that the given function represents exponential decay function and rate of decrease is 2.6%

The rate of change of the linear function for the given table is determined as: C. 120.
What is a Linear Relationship Function?A linear relationship function is represented as a straight line graph which can be expressed as a linear equation in slope-intercept form as, y = mx + b.
The rate of change of the function is represented as m, which is also the slope of the graph, and the y-intercept is b.
How to Find the Rate of Change of a Function?A linear function has a rate of change/slope which can be found using the formula:
m = y2 - y1/x2 - x1.
Given the set of table values that represents a linear function below, we can use two pairs of values to find the rate of change as follows:
(0.5, 60) = (x1, y1)
(1.5, 180) = (x2, y2)
Plug in the values
Rate of change (m) = (180 - 60)/(1.5 - 0.5)
Rate of change (m) = (120)/(1)
Rate of change (m) = 120
Therefore, the rate of change of the linear function for the given table is determined as: C. 120.
