Which inequality does not belong with the other three? Explain your reasoning
The inequality does not belong with the other three is - 1 ≤ x/1.25.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given,
1. 4x ≥ 12 ⇒ x ≥ 3.
2. - 1 ≤ x/5 ⇒ - 5 ≤ x.
3. 12 > x/1.25 ⇒ x < 15.
4. 2.5x > - 6.4 ⇒ x > - 2.56.
x ≥ 3 and x < 15 is, 3 ≤ x < 15.
- 5 ≤ x and x > - 2.56 here one common region is x > - 2.56 so - 5 ≤ x does not fit.

The transformations of f(x) are (b) horizontally shrunk by a factor of 1/4, vertically stretched by a factor of 5 and then reflected across the x-axis
How to describe the transformation from the parent function?From the question, we have the following function that can be used in our computation:
f(x) = x²
g(x) = -5(4x)²
Mathematically, these equations can be represented as
g(x) = -5f(4x)
The above equations implies that, we have the transformation to be:
The 4x implies that the function f(x) is horizontally shrunk by a factor of 1/4The -5 implies that the function f(x) is vertically stretched by a factor of 5 and then reflected across the x-axisHence, the transformed function is (b(

Exponential functions
An exponential function is a Mathematical function in the form f (x) = ax, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.
An exponential function is defined by the formula f(x) = ax, where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x.
The exponential function is an important mathematical function which is of the form
f(x) = ax
Where a>0 and a is not equal to 1.
x is any real number.
If the variable is negative, the function is undefined for -1 < x < 1.
Here,
“x” is a variable
“a” is a constant, which is the base of the function.
An exponential curve grows, or decay depends on the exponential function. Any quantity that grows or decays by a fixed per cent at regular intervals should possess either exponential growth or exponential decay.

There were 234 roses growing in the back garden. If 50% of the roses were red. How many were not red?
Answer:
C)117
Step-by-step explanation:
50%=1/2
If you want to figure out how much is left of a half all you do is have to divide the total number of whatever it is, in this case, its roses, by 2.
So now that we know that, let's get started.
234/2=117
Which we know is correct because it's one of your answer choices.
So 117 roses are not red. The other half was.

Kathryn runs from the north west corner to the southeast corner of a rugby field and Mia runs from the northeast corner to the southwest corner. Mia says she ran farther
Mia is incorrect, as they both ran the same distance, which is the hypotenuse of a right triangle of dimensions 10m and 16m.
What is the Pythagorean Theorem?The Pythagorean Theorem is a geometry axiom which states that for a right triangle, the length of the hypotenuse squared is equals to the sum of the lengths of the sides squared.
The sides are between the angle of 90º, while the hypotenuse is the segment that connects the sides.
From the image given at the end of the answer, the distances ran from each of them are equal, which is the hypotenuse of a right triangle of dimensions 10 m and 16 m, thus the distance is obtained as follows:
d² = 10² + 16²
d = square root of (10² + 16²)
d = 18.87m.

Linear quadratic systems
The solution of the given system of equations is (-1, 2).
What is system of equations?
A group of equations involving one or more variables is known as a system of equations. The variable mappings that satisfy each component equation, or the points where all of these equations intersect, are the solutions to systems of equations.
Consider, the given system of equations.
x^2 - x + 3y - 8 = 0 ..(1)
x - y + 3 = 0 ..(2)
From equation (2),
x = y - 3 ..(3)
Plug the value of x in equation (1).
⇒ (y - 3)^2 - (y - 3) + 3y - 8 = 0
y^2 - 6y + 9 - y + 3 +3y - 8 = 0
y^2 - 4y + 4 = 0
y^2 - 2y - 2y + 4 = 0
y(y - 2) - 2(y - 2) = 0
(y - 2)(y - 2) = 0
(y - 2)^2 = 0
y = 2
Now plug y = 2 in equation (3)
x = 2 - 3
x = -1
hence, the solution of the given system of equations is (-1, 2).

through the point (6, 8)?
A. y=-x+10
OB. y--x+8
OC. y-x+6
OD. --x+4
The perpendicular equation is y = -1/3x + 10 Option A
How to find perpendicular of an equation?You can find this by first realizing that perpendicular lines have opposite and reciprocal slopes. So since it starts at 3 we flip it and make it a negative and the new slope is -1/3.
Now we can use that and the point to get the y intercept using slope intercept form.
y = mx + c
m = gradient of the line
c = y -intercept
8 = (-1/3)(6) + c
8 = -2 + c
10 = c
And now we can use our new slope and new intercept to model the equation. y = -1/3x + 10

a poll is conducted the day before an election for state senator. there are two candidates running. the poll shows that 53% of the voters surveyed favor the republican candidate, with a margin of error of 2.as percentage points. should the republican be confident that she'll have a victory party? why or why not?
The lower limit of the confidence interval is 51%, which is above 55%, so the Republican should expect to win.
What does confidence interval mean?
Your estimate's mean plus and minus the range of that estimate's fluctuation is called a confidence interval.
If you repeat your test, you can expect your estimate to fall between these numbers with a reasonable degree of certainty. In statistics, confidence is another word for probability.
A confidence interval of proportions has two bounds, a lower bound and an upper bound.
These bounds depend on the sample proportion and the margin of error.
The lower bound is the sample proportion subtracted by the margin of error.
The upper bound is the margin of error added to the sample proportion.
In this problem, we have that:
Sample proportion 53%
Margin of error 2%
53 - 2 = 51%
53 + 2 = 55%
Hence, the lower limit of the confidence interval is 51%, which is above 55%, so the Republican should expect to win.

The equation
models the balance y after x months:
Answer:
Zachary pays $150 per month for his computer
Step-by-step explanation:
after 2 months:
2x + 1100y = 1400..... equation 1
after 4 months:
4x + 800y = 1400...... equation 2
we can either multiply equation 1 by 2 or we can divide equation 2 by 2, the purpose is simply to get the x values equal so it can be eliminated from the equation.
dividing equation 2 by 2:
2x + 400y = 700 ...... equation 3
Now equation 1 minus equation 3:
0x + 700y = 700
700y = 700
y = 700/700
y = 1
substituting y=1 into equation 3
2x + 400(1) = 700
2x = 700 - 400
2x = 300
x = 300/2
x= 150
Therefore it is concluded that Zachary has a payment plan where he pays $150 each month for the computer

What is the linear equation?
A linear equation is an equation of a straight line, written in the form y = mx + b. In this equation, m is the slope of the line and b is the y-intercept. Linear equations are used to describe relationships between variables, and they can also be used to solve problems with multiple unknowns. For example, if you know the slope of a line and the y-intercept, you can use a linear equation to calculate the x-intercept. Linear equations can also be used to model real-world situations, such as calculating the cost of a product or the amount of money saved over a period of time.
We have given:
the value of 35x + 10y, When x=8 and y=5.
Using substitution, substitute the given values of x and y.
35x + 10y
35(8) + 10(5)
