The ordered pair that describes the location of M' is (-5, -1)
How to determine the ordered pair that describes the location of M?From the question, we have the following parameters that can be used in our computation:
Point M = (5, -1)
This point can be represented as
(x, y) = (5, -1)
Also, from the question, we have the transformation to be:
Point M is reflected over the y axis
Mathematically, this can be expressed as
(x, y) = (-x, y)
So, we have
Point M' = (-5, -1)
Hence, the image is (-5, -1)

Over a four month period the price of an ounce of gold steadily increased from
$1000 to $1400. What was the monthly multiplier? What was the monthly
percent increase?
Answer:
%10
Step-by-step explanation:
If the gold steadily increased $400 over a four-month period, we need to figure out how much the gold increased each month.
400 ÷ 4 = 100
Now that we figured out that the gold steadily increased $100 every month, we now need to figure out what percent it grew.
1000 ÷ 100 = 10
The price grew %10 every month.

What is an isosceles triangle?
An isosceles triangle in geometry is a triangle with two equal-length sides. It can be stated as having exactly two equal-length sides or at least two equal-length sides, with the latter definition containing the equilateral triangle as an exception.
3x - 5 = y + 12 (if two angles of a triangle are equal, the sides opposite
them are also equal) ------------(1)
Also, 3x - 5 = 5y - 4 (sides of a equilateral triangle are equal)
So, 5y - 4 = y + 12
5y - y = 12 + 4
4y = 16
y = 4
Now,
Put value of y in equation (1)
3x - 5 = y + 12
3x = 4 +12 + 5
3x = 21
x = 7
Hence, x = 7 and y = 4

Write the equation of the line in point-slope form. (hint the y intercept is (0, -5)
show work
the area of the triangle formed by the x and y intercepts of the parabola y=0.5(x-3)(x+k) is equal to 1.5 square units. find all possible values of k.
The possible values of k are -0.56, -3.56, -2 and -1.
Find all possible values of k ?We have the equation of the parabola, y = 0.5 (x- 3 ) ( x+ k)
Substituting x=0, we get that i.e. y =0.5 * (-3) * k -1.5k
So, the y-intercept is (0,-1.5k).
Thus, the height of the triangle becomes |-1.5k| = 1.5k
Again, substituting y=0, 0 = 0.5 (x-3) (x+k) i.e. i.e. x0=(x-3) (x+k)=3 and x=-k
So, the x-intercepts are (3,0) and (-k,0).
Thus, the base of the triangle is 3+k if k>-3 or -3-k if k<-3.
As, area of a triangle = 1/2 * (base )* (height )
Substituting the values, we get,
1.5=1/2 *(3+k)*(1.5k)
i.e.3= 4.5 k + 1.5k ²
i.e. k = -0.56 and k = -3.56
or
1.5=1/2* (-3-k )*(1.5k)
i.e.
3 = -4.5 k - 1.5²
i.e. k = -2 and k = -1.
Thus, the possible values of k are -0.56, -3.56, -2 and -1.

Victoria needs to order some new supplies for the restaurant where she works. The restaurant needs at least 673 glasses. There are currently 368 glasses. If each set on sale contains 10 glasses, write and solve an inequality which can be used to determine xx, the number of sets of glasses victoria could buy for the restaurant to have enough glasses.
Number of glasses Victoria need to buy for restaurant are at least 31 from the inequality given by 10x + 368 ≥ 673.
As given in the question,
Number of glasses required in the restaurant at least 673.
Number of glasses currently available in the restaurant = 368
Number of glasses in each set used to sale = 10
Let 'x' represent the number of sets of the glasses Victoria need to buy.
Required inequality is given by :
10x + 368 ≥ 673
⇒ 10x + 368 - 368 ≥ 673 - 368
⇒ 10x ≥ 305
⇒ x ≥ 30.5
Number of sets bought by Victoria = At least 31
Therefore, from the inequality 10x + 368 ≥ 673 the number of sets of glasses bought by Victoria is equal to at least 31.

Using the interest rate formula, we know that the simple interest rate on the loan is 5.75%.
What is the simple interest rate?Simple interest is calculated by multiplying the principal by the time, interest rate, and time period.
"Simple Interest = Principal x Interest Rate x Time" is the written formula.
The simplest method for computing interest.
So, the interest rate on the loan is:
Formula to be used: I = p*r*t
Where I am the interest, p is the principal amount, r stand for rates and t stands for time.
I = p*r*t
3450 = 3000*2*r
3450/6000 = r
r = 0.575%
That is a 5.75% interest rate
Therefore, using the interest rate formula, we know that the simple interest rate on the loan is of 5.75%.

(−2, −4); −∞ < y < ∞
(−2, −4); −4 ≤ y < ∞
(0, −4); −∞ < y < ∞
(0, −4); −4 ≤ y < ∞
The vertex of y = |3x + 6| − 4 is (-2, -4) and the range of y = |3x + 6| − 4 is −4 ≤ y < ∞.
What is meant by vertex?A parabola's vertex is the location at which it crosses its axis of symmetry. The vertex will be the lowest point on the graph, or the point at the base of the "U"-shape, if the coefficient of the x2 term is positive.
The point is called the vertex (h, k). As we are all aware, a parabola's conventional equation is y = ax2 + bx + c. The bottom of the U-shaped curve is where the vertex is located if the coefficient x2 is positive, and the top of the curve is where the vertex is located if it is negative.
Given,
y = |3x + 6| − 4
The vertex of y = |3x + 6| − 4 is,
We have to find the absolute values zeroes,
3x+6=0
x= -2
To find the value of y, substitute x value in the above,
y= -4
(x, y)=(-2, -4)
Therefore, the vertex of y = |3x + 6| − 4 is (-2, -4)
And now,
The range of y = |3x + 6| − 4 is,
It can be defined by f(x)≥k
k= -4
f(x)≥ -4
Therefore, the range of y = |3x + 6| − 4 is −4 ≤ y < ∞.

suppose that for a science project you wanted to find exactly how much the length of a shadow changes during the day. how would you make this observation?
You should cast a shadow for a person or item at least three times and measure it each time to determine how the length of the shadow varies during the day.
The shape of an object always dictates the shape of its shadow. A shadow's size and shape can alter, though.
For instance, the location of the light source can induce these variations. The length of the shadow is influenced by the sun's position in the sky on a sunny day.
We can achieve the same effect indoors by adjusting the position of a flashlight reflecting on an object.
When the sun is low on the horizon, the shadows are lengthy, and when the sun is high, the shadows are considerably shorter.
So, To determine the change of length of object during the day, one should cast a shadow at least three separate times for a person or object and measure it each time

Estimate −74.41- 55.816 by first rounding each number to the nearest whole number.
PLEASE HELP!!!
Answer: -130.
Step-by-step explanation: To round −74.41 to the nearest whole number, we look at the tens place, which is the digit 4 in the number −74.41. Since 4 is less than 5, we round down to the previous whole number, which is −74.
To round 55.816 to the nearest whole number, we look at the tens place, which is the digit 8 in the number 55.816. Since 8 is greater than or equal to 5, we round up to the next whole number, which is 56.
Now that we have rounded both numbers to the nearest whole number, we can easily subtract them to get an approximate answer:
-74 - 56 = -130
Therefore, an approximate solution to −74.41- 55.816 is -130.

It is a first-degree polynomial equation, which means that the largest exponent of the variables is 1. Since a and b are constants and x and y are variables, linear equations have the general form ax+by=c. A straight line forms on a coordinate plane when the values of x and y fulfil the expression. The connection between two variables or the price of a product are two examples of real-world events that are frequently modelled using linear equations. Solving a linear equation entails determining the values of the variables that make the equation true.
