Follow the guided instructions below to create the line of reflection that would map the pink figure onto the blue figure.
Answer:
Slope of one of the dotted lines:
[tex]y=x[/tex] or [tex]y=x+5[/tex]
Slope of the line of reflection:
[tex]y=-x[/tex]
Step-by-step explanation:
When seeing the dotted lines, both of them have a rise & run of 1, indicating that y = x. However, one of the lines has a y-intercept of 5, making it y = x + 5. So, the slopes for the dotted lines are [tex]y=x[/tex] or [tex]y=x+5[/tex].
The line of reflection has a rise & run of -1, and goes through the origin, indicating that the equation is y = -x.

logs (20x + 5y) using the properties of logarithms to expand
The logarithmic expansion of logs(20x + 5y) by using the properties of logarithmic is log(5)+log(4x+y).
The basic logarithmic function is of the form f(x) = logₐx(r)n = logₐx, where a > 0. It is the inverse of the exponential function aⁿ = x. Log functions include natural logarithm (ln) or common logarithm (log). Logarithmic functions is very useful in various mathematical computations.
Given that, log(20x+5y) and we have to expand it by using the properties of logarithms. So, let's proceed to solve the question.
log(20x+5y)
we can write 20 in terms of powers like 20 = (2²)x5
log((2².5)x+5y)
log(5(2².5x/5+5y/5))
log(5(2²x+y))
log(5(4x+y))
∵ log(ab) = log(a)+log(b)
⇒log(5(4x+y)) = log(5)+log(4x+y)
Hence, on expanding log(20x+5y) by using the properties of logarithms we get log(5)+log(4x+y) as our required answer.

Write equation in slope-intercept form (9,-5) slope -4/3
The equation of the line in slope intercept form is y = (-4/3)x + 7.
According to the slope intercept form, the equation of a line is given as-
y = mx + c
where m is the slope and c is the y intercept.
Here we are given that an equation passes through the point (9,-5) and has a slope of -4/3.
According to the point slope form, the equation of a line passing through (x1, y1) and slope m is given as-
(y - y1) = m(x - x1)
Here,
x1 = 9, y1 = -5 and m = -4/3
Thus,
(y + 5) = -4/3(x - 9)
3(y + 5) = -4(x - 9)
3y + 15 = -4x + 36
3y = -4x + 21
y = (-4/3)x + 21/3
y = (-4/3)x + 7
This is our equation in slope intercept format as m = -4/3 and c = 7
Thus, the equation of the line in slope intercept form is y = (-4/3)x + 7.

Solve 19×50 numerically
The solution of expression 19×50 is found as 950.
What is defined as the distributive property?This property states that multiplying the product of two or more addends by a number produces the same outcome as multiplying each addend separately by the number and afterwards adding the products together.
The distributive property holds true for division the same way that it holds true for multiplication. However, with division, the concept of "breaking apart" or "distributing" can only be applied by dividing the numerator into lesser numbers that are exactly divisible even by divisor.In other words, the distributive property requires a phrase of the form:
A (B + C) can be simplified as A (B + C) = AB + AC.
This same applies foe the subtraction;
Thus, for the given numerical;
= 19×50
Using distributive property.
= (20 - 1)×50
Open the braces;

Option A is correct, 5.025 x 10¹⁰ is 335 times larger than 1.5 x 10⁸.
To determine how many times larger one number is than another, we divide the larger number by the smaller number.
In this case, we want to find how many times larger 5.025 x 10¹⁰ is than 1.5 x 10⁸.
Dividing the larger number by the smaller number:
(5.025 x 10¹⁰) / (1.5 x 10⁸)
To simplify, we can divide the coefficients (5.025 / 1.5) and subtract the exponents (10¹⁰ - 10⁸):
(5.025 / 1.5) x 10¹⁰⁻⁸
Evaluating the division of the coefficients:
(3.35) x 10²
Therefore, 5.025 x 10¹⁰ is 3.35 x 10² times larger than 1.5 x 10⁸.
In decimal form, this can be expressed as:
3.35 × 10² = 335
Therefore, 5.025 x 10¹⁰ is 335 times larger than 1.5 x 10⁸.
