Answer:
Answer: The point (1, 2) is not a solution to the system of equations because it does not satisfy the equation 3x + y = –2.
Step-by-step explanation:
System of Equations
Consider the following system of equations
2x + 3y = 8 [1]
3x + y = -2 [2]
And the point (1,2). Substituting in both equations:
For equation [1]:
2*1 + 3*2 = 8
2 + 6 = 8
8 = 8
Since the equation is true, point (1,2) satisfies the equation 2x + 3y = 8
Now for equation [2]:
3*1 + 2 = -2
3 + 2 = -2
5 = -2
Since this equation is false, point (1,2) does not satisfy the equation 3x + y = -2
Answer: The point (1, 2) is not a solution to the system of equations because it does not satisfy the equation 3x + y = –2.
Answer:
B: The point (1, 2) is not a solution to the system of equations because it does not satisfy the equation 3x + y = –2.

Which phrase represents the expression 7x + 2?
a. seven times two plus a number
b. two times a number plus seven
c. two less than a number multiplied by seven
d. a number multiplied by seven then added to two
Answer:
D should be the correct answer:) hope this helps:))
The phrase represents the expression 7x + 2 is the number multiplied by seven then added to two, So Option D is correct
What are expressions?
An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.
For example, 2x+3
Given that,
An expression,7x + 2
here, 7 is coefficient
x is variable
And then in 7x, constant number 2 is added
So it can be state that a number multiplied by seven then added to two
So, the statement is 7 multiplied in number then 2 is added

Jenny selects a box of cereal for her family at the supermarket. Across town, Chase also happens to pick out a box of cereal for his own family. Are these two events dependent or independent?
Answer:
Independent
Step-by-step explanation:
In clear and simple terms, Events A and B are sid to be independent if the occurrence of event A and event B can occur simultaneously, that is the occurrence of A does not affect or stop the occurrence of B at the time.
The events being compared can happen concurrently with Jenny and chase both making selection for their respective families. However, events which cannot occur together are called mutually exclusive events such as obtaining a head and tail from a single coin toss, this events cannot happen together and are thus not independent.

The product of (3 - 4) and (blank)
is 25.
Answer:
-25
Step-by-step explanation:
Since product mean multiply, we multiply (3-4) and (blank), which we'll call "n".
(3-4)n = 25
subtract in parentheses
(-1)n = 25
remove parentheses
-1n = 25
swap signs
n = -25

A triangle has a base of 10 centimeters and a height of 12 centimeters. A rectangle has a base of 10 centimeters and a height of 12 centimeters.
What are the areas of the figures?
The area of the triangle is
___ cm2.
The area of the rectangle is
___ cm2.
The area of the triangle is
60 cm2.
The area of the rectangle is
240 cm2.
In a two-dimensional plane, an area of triangle is equal to the sum of the areas of its three sides.
To calculate a rectangle's area, count the number of square units that fit within the rectangle's perimeter.
Area of triangle = h x b / 2
Given
h = 12
b =10
hence
A= h x b / 2
= 12 x 10 / 2
= 120 / 2
= 60 cm2
Area of rectangle = l x b
Given
l = 12
b = 10
hence
area of rectangle = l x b
= 12 x 10
= 120 cm2

MODELING REAL LIFE The table shows the profit y for recycling x pounds of aluminum. Find the profit for recycling 75 pounds of aluminum. Aluminum (lb), x 10 20 30 40 Profit, y $4.50 $9.00 $13.50 $18.00
Answer: 33.75
Step-by-step explanation:
It’s right
There is a profit of $33.75 for recycling 75 pounds of aluminum.
What is Function?A function is a relation from a set to another set such that element in the first set only maps to one element in the other set.
A function f from a set A to a set B can be represented as f : A → B
We have,
Profit for recycling 10 lb Aluminum = 10/10 × 4.5 = 4.50
Profit for recycling 20 lb Aluminum = 20/10 × 4.5 = 9.00
and so on
Therefore, we can write this as a function.
f(x) = [tex]\frac{x}{10}[/tex] × 4.5
We have to find the profit for recycling 75 pounds of aluminum.
f(75) = [tex]\frac{75}{10}[/tex] × 4.5
= 7.5 × 4.5
= 33.75
Hence the profit for recycling 75 pounds of aluminum is $33.75.

Step-by-step explanation:
We can test values in the equation selected from points on the graph. (-4,0)x intercept. (-2,-4)vertex
0 = (-4 +2)² -4
0 = (-2)² -4
0 = 4 - 4 true
-4 = (-2+2)² -4

A square is cut diagonally into two equal parts. If each part has an area of 50 cm2, then what is the perimeter of each part?
Answer:
30cm
Step-by-step explanation:
Given data
When are square is cut diagonally into two parts
The resulting shape is a triangle
hence the area of the square = 50+50 = 100cm^2
The length of each side of the square = √100= 10cm
likewise the diagonal of the square = 10cm
Hence the perimeter of the resulting triangle= 10+10+10= 30cm
The bronx zoo opened at 9.00 am. In the first hour 280 people purchased admission tickets. In the second hour 25 percent more people purchased admission people than the first hour . Each ticket cost 16.25. What was the total amount of money paid for all the tickets purchased in the first two hours
Answer:
Total amount paid for tickets in the two hours = $10,237.50
Step-by-step explanation:
Step 1
Ist Hour, 280 tickets were sold at the cost of $16.25
Amount of money made in the first hour= Number of people who purchased ticket x price of a ticket
=280 x 16.25 =$4,550
2nd Hour, 25 % more people purchased ,
which means the total number of people who purchased tickets =
1.25 x 280= 350
Amount of money made in second hour = Number of people who purchased ticket x price of a ticket 350 x 16.25 =$5,687.5
Step 2
Total amount paid for tickets in the two hours = Amount of money made in the first hour +Amount of money made in second hour
=$4,550+ $5,687.5
=$10,237.50
