So I am looking at the method of elimination but I get a little bit lost why there is a positive +1 underneath the -1 , where does the +1 come from?
Answer:
it is because its being carried to the other side
Step-by-step explanation:
When you add 1 to negative 1 it becomes 0, so we are trying to make the right hand side equal to the left hand side. If that makes any sense.

The length between the bases on a baseball field is 90 ft. A scale drawing shows the distance between the bases as 2 1/2 inches. One inch on this drawing equals how many feet?
Divide total feet by total inches
90 feet / 2 1/2 inches = 36 feet per inch
1 inch = 36 feet

if x=3,y= -2(negative 2) and z=6 what is 4xy-z
Answer:
Step-by-step explanation:
4 * 3 = 12
4 * -2 = -8
12 * -8 = -96
= -90
Use the following information to determine tan(2x).
cos(x)=2/3 and sin(x) is negative
We have
tan(2x) = sin(2x) / cos(2x)
tan(2x) = (2 sin(x) cos(x)) / (2 cos²(x) - 1)
Recall that
sin²(x) + cos²(x) = 1
and since sin(x) is negative, it follows that
sin(x) = - √(1 - (2/3)²) = -√5/3
Then
tan(2x) = (2 (-√5/3) (2/3)) / (2 (2/3)² - 1) = 4√5

Researchers asked 300 families whether or not they were homeowners and how many cars they had. Their responses are summarized in the following table.
(a) What percentage of the families are not homeowners?
(b) What percentage of the families have two or more cars?
Answer:

Step-by-step explanation:
simply use 300 as your denominator
60/300 = 20
123 / 300 = 41
Based on the row relative frequencies in the table above, which statement is true? A There is an association between type of pet and food preference because the row relative frequencies are similar for the dog and cat rows B There is an association between type of pet and food preference because the row relative frequencies are not similar for the dog and cat rows There is not an association between type of pet and food preference because the row relative frequencies are similar for the dog and cat rows There is/not an association between type of pet and food preference because the row relative frequencies are not similar for the dog and cat rows
The conclusion that can be drawn from the table is (c) There is not an association between type of pet and food preference because the row relative frequencies are similar for the dog and cat rows
What is conditional relative frequency?A conditional relative frequency is simply a two-way table that shows the relationship between table entries
How to determine the association?The table is given as:
Food preference
Dog 0.47 0.52 0.495
Cats 0.53 0.48 0.505
Total 1 1 1
The entries at rows 1 and 2 i.e. 0.47 and 0.52 & 0.53 and 0.48 are close.
This means that there is no association between them because of the closeness
Hence, the conclusion about the association is (c)

[tex]4x-5y-4x=20-4x[/tex] [tex]-5y=-4x+20[/tex]Step 2: Divide both sides by -5.

Answer:
506, 12 miles
Step-by-step explanation:
Find the measurements of a mile in centimeteres
1 mile= 160934 cm
Mulitply the miles by the amount of centimeteres in a mile.
248 x 160934= 39911632
Divide it by measurement on map to find the measurement of 1 cm on the map to real life measurement in cm
39911633 ÷ 4,9= 8145231,02 cm
Once you have the ratio multipyly it by measurement on map
10 x 81452310,2
Then divide by the amount of cm in a mile
81452310,2÷160934=506,12 miles
Sorry if this is wrong.
Kansas City and St. louis are 248 miles apart. On a map, these two cities are 4.9 cm apart. Using unitary method, the distance between Kansas City and Louisville is 506 miles (approximately) if they at 10 cm apart on the map.
What is map?Making a map or using a matching procedure wherein the points of one set are compared to the points of another provides the definition of mapping. Making a map to find your residence is an aspect of mapping.
What is unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
4.9 cm on a map in reality = 248 miles1 cm on a map in reality = 248/4.9 = 50.61 miles10 cm on a map in reality = 50.61 * 10 = 506.1 miles.
Therefore, Kansas City and St. louis are 248 miles apart. On a map, these two cities are 4.9 cm apart. Using unitary method, the distance between Kansas City and Louisville is 506 miles (approximately) if they at 10 cm apart on the map.

How to Solve Algebra expression?6 (d - f) + f
when d = 4 7/8 and f = 3 1/2
Given the data in the question;
d = 4 7/8 = f = 3 1/2 = What is 6 (d - f) + f = ?First, we convert the mixed fraction into an improper fraction
d = 4 7/8 = ( 8×4 + 7 )/8 = 39/8
f = 3 1/2 = ( 2×3 + 1 )/8 = 7/2
Now, we substitute the values of d and f into the expression.
234/8 - 42/2 + 7/2

Part (a)
The notation [tex]A \cap B \cap C[/tex] talks about overlapping or intersecting all three intervals. Your teacher wants to know what numbers are in all three intervals at the same time.
Refer to the diagram below. I've graphed regions A, B and C on the same number line. The vertical separation is to help tell the regions apart. Technically they should all be on the same number line. Notice how the regions overlap on the interval (0, 2] which translates over to [tex]0 < x \le 2[/tex] telling us that the answer must be choice D.
Meaning we exclude 0 but keep 2, and everything in between the endpoints.
Choice C is not possible because x = -1 is not in region C. This means choice A is ruled out also. Choice B is eliminated because x = 3 is not in region A nor region B.
Answer: Choice D=============================================================
Part (b)
As mentioned earlier, the intervals all have in common the region between x = 0 and x = 2. We exclude 0 but keep 2.
Answer: (0, 2]=============================================================
Part (c)

We have an open circle at 0 and a closed circle at 2. There is shading in between those endpoints.
