Scale factor required to map the first line segment onto second line segment is 3/9=0.33
What is scale factor?The scale factor is the ratio of the length of the image to the length of the pre-image.
In this case, we're looking for the that would map the first line segment (length 9cm) onto the second line segment (length 3cm).
To find the scale factor, we can divide the length of the image by the length of the pre-image:
scale factor = length of image / length of pre-image
In this case:
[tex]ScaleFactor=\frac{Length Of Image}{Length Of Pre-image}[/tex]
[tex]scale factor = 3cm / 9cm = 1/3=0.033[/tex]
So the scale factor to map the first line segment onto the second line segment is 1/3.
It means the 1st line is 3 times longer than the second one.

Zendaya has $540 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
She buys a new bicycle for $269.88.
She buys 4 bicycle reflectors for $10.57 each and a pair of bike gloves for $17.76.
She plans to spend some or all of the money she has left to buy new biking outfits for $65.65 each.
Write and solve an inequality which can be used to determine

Plsss help!!
Answer:
269.88 +4(10.57) +17.76 +65.65x ≤ 540x ≤ 3.2; 3 outfits or lessStep-by-step explanation:
After spending $269.88, 4 times $10.57, and $17.76 of her $540 budget, you want to know how many (x) outfits Zendaya can buy at $65.65 each.
InequalityThe total of Zendaya's spending must be no more than her budget amount:
269.88 +4(10.57) +17.76 +65.65x ≤ 540
SolutionSimplifying the inequality gives ...

Therefore ,the result is. It means that there exist 17 units between the two points supplied as the answer to the given distance problem.
Specify the distance.An object's travels are quantified by distance. Simply explained, distance, or t, is the amount of space an object covers within a specific period of time. Displacement is still the quickest route a moving object can travel. We frequently take into account the concepts of range and displacement.
Here,
6 and -3 are given (2, -2)
Points (a, b) and (c, d) are now separated by
d= √(c-a)² + ( d- b) ²
d= √(-3+2)² + (2-6)² as a result.
=>d = √ 1 + 16 = √17

The multiplication of the algebraic expressions gives x⁴ + 1.5x³ - 2x²
How to perform multiplication on algebraic expressions?An algebraic expression is an expression that consists of variables, constants, and a finite number of algebraic operations (such as addition, subtraction, multiplication, and division) e.g. 2x + 25
In order to perform the multiplication, you use expression outside the parenthesis to multiply the expressions inside the parenthesis one after the other. That is:
-0.5x²(-2x² - 3x + 4) = -2x²(-0.5x²) - 3x(-0.5x²) + 4(-0.5x²)
= 1x⁴ + 1.5x³ - 2x²
= x⁴ + 1.5x³ - 2x²

The angle measure of m∠CAF = 23°.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Given:
The angle measures,
m∠EBG = 23°
m∠CAE = 52°
From the figure,
m∠EBG = m∠FAE = 23°
So, from the figure,
m∠CAE = m∠CAF + m∠FAE
Substituting the angle measures,
52 = m∠CAF + 23
m∠CAF = 52 - 23
m∠CAF = 22°
Therefore, 23° is the angle measure of m∠CAF.

Absolute value equations and inequalities.
An absolute value equation is an equation that contains an absolute value expression. An inequality is a mathematical statement that compares algebraic expressions using greater than (>), less than (<), and other inequality symbols.
What are absolute value equations and inequalities?The absolute number of a number a is written as |a|
And represents the distance between a and 0 on a number line.
An absolute value equation is an equation that contains an absolute value expression. The equation IxI = a
Has two solutions x = a and x = -a because both numbers are at the distance a from 0.
To solve an absolute value equation as
x+7|=14
You begin by making it into two separate equations and then solving them separately.
x+7=14
x+7−7=14−7
x=7
or
x+7=−14
x+7−7=−14−7
x=−21
An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative.
The inequality |x|<2 represents the distance between x and 0 that is less than 2 Whereas the inequality |x|>2 represents the distance between x and 0 that is greater than 2.
You can write an absolute value inequality as a compound inequality.
$$\left | x \right |<2\: or

The number which has a finite number of digits after the decimal point is a terminating decimal.
The decimal is said to be terminating decimal if that has a finite number of digits after the decimal point. Decimal numbers are used to represent the partial amount of whole just like fractions. The number which has a finite number of digits after the decimal point is referred to as a terminating decimal. A number has a terminating decimal expansion if the digits after the decimal point terminate or are finite. The fraction 5/10 has the decimal expansion of 0.5 which is a terminating decimal expansion because digits after the decimal point end after one digit. Terminating decimal has finite digits and non-terminating decimals do not have finite digits. A number with a terminating decimal is always a rational number.

should have a slope of 0.06.
You need to find the length of your bridge if it has a slope of 0.06. This will tell you how much

work, 1 point for the solution)
5. How long is the deck of the bridge? Show how you calculated r. (3 points: 2 points for work, 1
point for the solution)
Answer:
The change in y-axis with respect to change in x-axis is described as slope.
the slope is 0.06, rewrite it as a fraction
the base of the bridge is 50 and height of the bridge is 3, find the hypotenuse using the Pythagorean theorem to get the length of the bridge.

Is an absolute value graph increasing or decreasing?
The function increases on [0,∞] and decreases on [-∞,0]. The absolute minimum value of f is 0, and its relative minimum value is the same (0,0).
Explain the nature of absolute value graph?When x< 0, you can see on the graph that there is a "open circle" at (0, 0).
This is owing to the fact that the points on y = x approach (0, 0) as that of the x-values reach 0, as we have already shown. Instead, the open circle was drawn since x must strictly be smaller than zero on just this stretch.A point at (0, 0) is filled in when x ≥ 0, which essentially "plugs" the hole represented either by open circle. Thus, we obtain:The function increases on [0,∞] and decreases on [-∞,0]. The absolute minimum value of f is 0, and its relative minimum value is the same (0,0).The absolute minimum value of f is 0, and its relative minimum value is the same (0, 0). The relative maximum value of F is zero.Thus, due to the graph's indefinitely high y values, there is likewise no absolute maximum value for f.

• Parallel lines have equal slopes
then slope of parallel line is 3
the equation of a line in point- slope form is
