f(x) = -x² + 5 and g(x) = -2x+2, find all values of x for which f(x) = g(x).
Answer:
The values of x for which f(x) = g(x) are:
x = -1x = 3Step-by-step explanation:
To find all the values of x for which f(x) = g(x), equate the given functions:
[tex]\implies f(x)=g(x)[/tex]
[tex]\implies -x^2+5=-2x+2[/tex]
Rearrange the equation so that it is in the quadratic form ax²+bx+c=0:
[tex]\implies -x^2+5+2x-2=0[/tex]
[tex]\implies -x^2+2x+3=0[/tex]
Divide both sides by -1:
[tex]\implies x^2-2x-3=0[/tex]
Factor the quadratic equation:
[tex]\implies x^2-3x+x-3=0[/tex]
[tex]\implies x(x-3)+1(x-3)=0[/tex]
[tex]\implies (x+1)(x-3)=0[/tex]
To solve for x, apply the zero-product property:
[tex](x+1)=0 \implies x=-1[/tex]
[tex](x-3)=0 \implies x=3[/tex]
Therefore, the values of x for which f(x) = g(x) are:
x = -1x = 3We can check the solutions by substituting each found value of x into the functions.
[tex]f(-1)=-(-1)^2+5=4[/tex]
[tex]g(-1)=-2(-1)+2=4[/tex]
[tex]f(3)=-(3)^2+5=-4[/tex]
[tex]g(3)=-2(3)+2=-4[/tex]
As f(-1) = g(-1) and f(3) = g(3), this proves that the values of x for which f(x) = g(x) are x = -1 or x = 3.
Equate Both equatios and find x
f(x)=g(x)-x²+5=-2x+2x²-5=2x-2x²-2x-3=0(x+1)(x-3)=0The points are -1,3

They walked 12.3 miles on first day and 8.2 miles on second day. The solution has been obtained by using linear equation.
What is a linear equation?
The linear equation with this degree of one is the largest. This shows that linear equations with exponents greater than one have no variables. Such an equation gives rise to a straight line on the graph.
We are given that a group of hikers walked from Hawk Mt. Shelter to Blood Mt. Shelter along the Appalachian Trail, a total distance of 20.5 mi which took them 2 days.
Let the distance traveled on first day be 'x'.
Since, on the second day, the hikers walked 4.1 mi less than they did on the first day so,
Distance traveled on second day = (x - 4.1)
From this, we get a linear equation as
⇒x + (x - 4.1) = 20.5
⇒2x - 4.1 = 20.5
⇒2x = 24.6
⇒x = 12.3
So, (x - 4.1) = 12.3 - 4.1 = 8.2 miles
Hence, they walked 12.3 miles on first day and 8.2 miles on second day.

The transformation of the triangle is the orientation changes and moves the triangle into Quadrant III
What is Reflection?Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images.
The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).
Given data ,

What exactly is a linear equation?
The equation is referred to as linear when a variable's maximum power is 1. A one-degree equation is another name for it. A linear equation in one variable has the conventional form Ax + B = 0. This equation has three variables: x, A, and B. A is a coefficient. A linear equation in which there are only two variables typically takes the form Ax + By = C. In addition to the constant C, there are three other constants: the variables x and y, the coefficients A and B, and the variables.
Now,
As given she has a debt of $25 that will be y-intercept.
and as we can see from graph she earns $39 in 4 hours that means $9.75 in an hour which will be slope of line also, then the line will be represented as

What exactly is dilation?
Dilation is the process of modifying the size of an item or form by reducing or expanding its dimensions according to specific scaling variables. A circle of radius 10 unit, for example, is reduced to a circle with radius 5 unit. This approach is utilised in photography, arts and crafts, and the creation of logos, among other things. There are four primary types of transformations in geometry. They are as follows:
RotationTranslationReflectionDilation or ResizingDilation Properties
Some characteristics of forms that stay constant during dilation changes are:
The figure's angles are all the same.The midpoints of the figure's sides stay the same as the midpoint of the dilated form.The figure's parallel and perpendicular lines stay the same as the dilated figure's parallel and perpendicular lines.The visuals stay unchanged.Now,

Can you always use synthetic division for dividing polynomials?
Yes, we can use always the synthetic division for dividing polynomials since it is the easiest way in order to get the quotients of two polynomials.
Dividing Polynomials:We use the division of polynomials to find the quotients of two polynomials. Two polynomials can be divided by simply multiplying and dividing by the largest power in each term.
The two different ways to divide polynomials are 1. Long division method and 2. The synthetic division method. The synthetic division method is the quickest way to divide polynomials between these two approaches.
Advantages of performing a Synthetic Division:
Only if the divisor is a linear factor can we use the synthetic division approach. In contrast to the long division method, which uses division and subtraction, the synthetic division approach uses multiplication and addition. There are just a few calculations needed. There is no need for variables to do the calculation.This method is less prone to errors than the polynomial long division method.

In science, the probability of an event is a number representing the probability that an event will occur. It is expressed as a number ranging from 0 to 1, or as a number ranging from 0% to 100% using percentage display. The more likely an event is to happen, the more likely it is to happen. The probability of an impossible event is zero. The probability of an event that must happen is 1. The probabilities of two complementary events A and B (A or B) add up to 1.
A simple example is a fair (unbiased) coin toss. When the coin is fair, the two possible outcomes (heads and tails) are equally likely. Since the two outcomes are complementary and the probability of heads is equal to the probability of tails, the probability of each of the two outcomes is 1/2.
