Drag each label to the correct location on the image. Identify which equations have one solution, infinitely many solutions, or no solution.
Answers
Answer:
"1/2y+3.2y=20" One solution
"15/2+2z-1/4=4z+29/4-2z" Infinitely many solutions
"3z+2.5=3.2+3z" No solution
"1.1+3.4x+2=3.1+3/4x" infinitely many solutions
"4.5r=3.2+4.5r" No solution
"2x+4=3x+1/2" one solution
To determine the number of solutions for each equation in the given image, we need to analyze each equation separately. Let's go through each equation and identify whether it has one solution, infinitely many solutions, or no solution.
Equation 1: 3x - 2y = 6 Equation 2: 6x - 4y = 12 Equation 3: 2x - y = 3
To find the solutions, we can use the method of substitution or elimination.
First, let's consider Equation 1: 3x - 2y = 6
If we rearrange this equation to solve for y, we get: y = (3x - 6) / 2
Now, let's examine Equation 2: 6x - 4y = 12
If we rearrange this equation to solve for y, we get: y = (6x - 12) / 4 y = (3x - 6) / 2
Comparing the two equations for y, we can see that they are the same. This means that Equation 1 and Equation 2 represent the same line.
In other words, they have infinitely many solutions.
Any point on the line formed by these equations satisfies both equations simultaneously.
Moving on to Equation 3: 2x - y = 3 If we rearrange this equation to solve for y, we get: y = 2x - 3
This equation represents a line with a specific slope and y-intercept. Since it is different from the line represented by Equation 1 and Equation 2, we can conclude that Equation 3 has one solution.
This means that there is a unique point of intersection between Equation 3 and the other two equations.
In summary: - Equation 1 and Equation 2 have infinitely many solutions since they represent the same line.
- Equation 3 has one solution since it intersects the other two equations at a unique point.

Answer:
a. 3 and 8
b. 17
c. 3x^2, 8x, and 17
Step-by-step explanation:
a. The coefficients of an equation are the numbers that come before the variables, in this case x. We can see there is a 3 multiplying x^2 and an 8 multiplying x, therefore the coefficients would be 3 and 8.
b. The constants are the numerical terms(ones without x). This would be 17.
c. Terms are the products of numbers and/or variables separated by addition or subtraction. These would be 3x^2, 8x, and 17.

What is Congruence?In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
Given here BD is common and AB=BC and since ∠A = ∠B also they share a common right angle therefore by default the other two remaining angles they must be equal by the angle sum property. Therefore opposite sides of a congruent angles must be equal.
Hence, by SSS property the triangles are Congruent.

Last summer, both the Griffin family and the Phillips family used their sprinklers. 15 hours of use by Philips family,40 hours of use by Griffin family for each sprinklers.
Given that,
Last summer, both the Griffin family and the Phillips family used their sprinklers.
The sprinkler used by the Phillips family produced 25L of water every hour.
The Griffin family's sprinkler produced 15L of water per hour.
The households utilized their sprinklers for a total of 55 hours in total, producing 975L of water.
We have to find how long did you use each sprinkler.
Let us take
p be hours of use by Philips family
55-p be hours of use by Griffin family
Now, we get
25p+15(55-p)=975
25p+825-15p=975
10p=975-825
10p=150
p=150/10
p=15
55-p=55-15=40
Therefore, 15 hours of use by Philips family,40 hours of use by Griffin family.

What is addition?Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.
Given:
A kilogram (kg) of bananas costs $2.40.
A kilogram of apples costs $3.55.
So, the price of 2 kilograms of apples cost 2 x 3.55,
= $7.1
To find the price of 1 kilogram of bananas and 2 kilogram of apples:
Addition,
The price = 2.40 + 7.1
The price = $9.5

Use the slope 2

The triangle below is isosceles. Find the length of side xx to the nearest tenth.
Answers
Answer:
x = 2
Step-by-step explanation:
Since this is an isosceles triangle the unmarked side is also √2
Since this is also a right triangle use the pythagorean theorem to find x.
x² = (√2)² + (√2)²
x² = 2 + 2
x² = 4
x = 2
The value of x is 2.
What is Pythagoras theorem?The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.
Given:
H= x, P= √2, B= √2
Now, using Pythagoras theorem
H² = P² + B²
x² = (√2)² + (√2)²
x² = 2 + 2
x² = 4
x = 2
Hence, the value of x is 2.

The difference between two whole numbers is 8. Twice the smaller number is 4 more than the larger number. What is the smaller number?
Answers
Answer: 12
Step-by-step explanation:
x - y = 8
2y = 4 + x
y = ?
x - y = 8
x = 8 + y
2y = 4 + x
2y = 4 + (8 + y)
2y = 12 + y
2y - y = 12
y = 12
The smallest number is 12.
Given that,
The difference between two whole numbers is 8. Twice the smaller number is 4 more than the larger number.Here we assume the larger number be x and smallest number be yBased on the above information, the calculation is as follows:
x - y = 8
2y = 4 + x
So,
x = 8 + y
Now
2y = 4 + (8 + y)
2y = 12 + y
2y - y = 12
y = 12
