Answer:
y = -x -1
Step-by-step explanation:
x1= 0, y1= -1
[tex]slope = \frac{x - x1}{y - y1} = \frac{x - 0}{y - ( - 1)} = \frac{x}{y + 1} [/tex]
-1 = x/(y+1)
-1 (y+1) = x
y+1 = -x
y= -x -1

for a person who understands natural logs (ln) vs logs. Why do we use (ln) to inverse an equation when there is no e in the original equation?
Answer:
Because e is used so commonly in math and economics, and people in these fields often need to take the logarithm with a base of e of a number to solve an equation or find a value, the natural log was created as a shortcut way to write and calculate log base e. ... So ln(x) = loge(x). As an example, ln(5) = loge(5) = 1.609.

Julie has put a map of the United States on a coordinate grid. Phoenix is at approximately (−2.4, −4.2) and Atlanta is at approximately (2.9, −4.2).
If each unit on the grid represents 300 miles, what is the approximate distance between Phoenix and Atlanta?
Explain how you could find the distance between a point and its reflection across the y-axis.
Answer:
I think it is 150 miles between Phoenix and Atlanta
Step-by-step explanation:
(2.9,-4.2)-(2.4,-4.2)=(0.5,0)
0.5 is half of 1 and 150 is half of 0.5

x - (-2) = 10
what is x
Answer:
x = 12
Step-by-step explanation:
x - (-2) = 10 | Given
x - 2 = 10 | Distribute (whenever there is a minus on the outside of a parenthesis imagine a -1 on the outside, and flip the signs of everything on the inside)
x = 12 | Add 2 to both sides.
Oscar charges $25 for the first hour of tutoring and $15 for each additional hour or fraction of an hour counting as a whole hour.
The rates that Latoya charges for x hours of tutoring are modeled with the function shown.
f(x)=30x,0≤x≤3
20x,3 6
(Imagine this stuff above as a piecewise function)
Complete to make a true sentence.
____ will charge $ ____ more to tutor for 5.5 hours.
Answer and explanation:
Since Oscar charges $25 for the first hour and $15 for every additional hour or fraction of an hour, his function would be :
f(x)= 25x 0 is less than or equal to x and x is less than or equal to 1
Latoya charges $30 for the first three hours and $20 for every additional hour or fraction of an hour. The function :
f(x)= 30x
0 is less than or equal to x and x is less than or equal to 3
Given that each taught their students for 5.5 hours, their charges would be :
For Oscar,
The first hour = 25×1= $25
4.5 hours left= 15×4.5= $67.5
Total charge for 5.5 hours= $67.5+$25= $92.5
For Latoya,
The first three hours= 30×3=$90
2.5 hours left= 2.5×20= $50
Total charge for 5.5 hours= $90+$50= $140
Therefore Latoya will charge $47.5 more to tutor for 5.5 hours.

2. Given g(t) = 5 + 2t, find each the value g(2)
Answer:
g(2) = 9
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Function NotationStep-by-step explanation:
Step 1: Define
g(t) = 5 + 2t
g(2) is t = 2
Step 2: Evaluate
Substitute in t: g(2) = 5 + 2(2)Multiply: g(2) = 5 + 4Add: g(2) = 9A welcome kit contains 3 grocery store and seven drugstore coupons. The coupons are worth $45. Another welcome kit contains three grocery store coupons and six drugstore coupons worth $42. What is the value of each grocery coupon and each drug store coupon?
Answer:
The value of each grocery store coupon is $6
Then the value of each drugstore coupon is $3.
Step-by-step explanation:
Let's define:
G = value of a grocery store coupon.
D = value of a drugstore coupon.
We know that:
"A welcome kit contains 3 grocery store and seven drugstore coupons. The coupons are worth $45"
We can write this as:
3*G + 7*D = $45
And we also know that:
"Another welcome kit contains three grocery store coupons and six drugstore coupons worth $42"
We can write this as:
3*G + 6*D = $42
Then we have the system of equations:
3*G + 7*D = $45
3*G + 6*D = $42
To solve this, we can isolate the term "3*G" in one of the equations (because it appears on both of them)
Let's isolate it on the second equation:
3*G = $42 - 6*D
Now let's replace this on the first equation:
($42 - 6*D) + 7*D = $45
$42 + D = $45
D = $45 - $42 = $3
Then the value of each drugstore coupon is $3.
And we also have the relation:
3*G = $42 - 6*D
We can just replace the value of D to get:
3*G = $42 - 6*$3 = $42 - $24 = $18
G = $18/3 = $6
The value of each grocery store coupon is $6

Answer:
he ate 12/12 which means the dinasour ate all of the plant
Step-by-step explanation:
i cant lie this is a wierd question cause it seems to obvious but here it is....
10/12+ 2/12= 12/12
12/12=1 whole the dinasour ate the entire plant
Answer: 10/12 + 2/12 = 12/12 or 1 whole
Step-by-step explanation: Since it says at first the dino ate 10/12 and then after it ate 2/12 more. When your adding fractions the denominator doesn't change but the numerator does. Therefore its basically saying what's 10+2 which = 12 then you put the denominator on the bottom which is 12/12 if you want to simplify it. It turns to a 1 whole

graph the image of V (3,–7) after a rotation 180° clockwise around the origin.
Answer and Step-by-step explanation:
It is in the screenshot.
The point is (-3, 7), and would be noted as V'.

Image of the point V is V' = (-3, 7) as shown in the graph below.
What is Coordinate Geometry?One of the most intriguing ideas in mathematics is called coordinate geometry. By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related. They can answer geometrical problems because it gives them geometrical aspects of algebra. In this area of geometry, a pair of ordered numbers is used to describe the location of points on a plane.
As per the given data:
Coordinates of point V = (3, -7)
Rotation to be given = 180° (clockwise)
For drawing the image of point V (3, -7):
Step 1: Draw a line passing through the origin and V (3, -7) extending through 2nd and 4th quadrant.
Step 2: Change sign of x and y coordinates as rotation is of 180° and mark the point in the 2nd quadrant.
Image of the point V is V' = (-3, 7) as shown in the graph below.
Hence, the image of the point V is V' = (-3, 7).

James has a rectangular plot of land that is 250 feet long and x feet wide. He wants to build a fence around the plot of the land. If the perimeter of the plot is 942 feet, what is the value of x?
Answer:
= 221
Step-by-step explanation:
Lenght = 250
Width= x
Perimeter = 2 (l+b) = 942
2 x (250 +x) = 942
500 + 2x = 942
2x = 942 - 500= 442
x = 442 /2 = 221
