The given equation is linear with two variables that will have zero solutions.
What is a system of equations?A system of equations, also known as an equation system or a set of simultaneous equations, is a finite set of equations for which common solutions are sought.
Given equation is x + 2y = 8. The equation is a linear equation with two variables. If the equation will have another equation then the solution will have two values for two variables.
If there is only one equation with two variables we will not get any solution we need one more same equation. The equation will have zero solution.
Therefore, the given equation is linear with two variables that will have zero solutions.

Question in picture please solve
Answer:
n=8
Step-by-step explanation:
-6=n/2-10 -- switch sides
n/2-10= -6 -- add 10 to both sides
n/2-10+10= -6+10 -- simplify
n/2=4 -- multiply both sides by 2
2n/2=4 times 2 -- simplify
n=8 -- answer
Which system of equations has no solution?
5 x + 5 y = 10 and 2 x + 2 y = 4
3 x minus 6 y = 4 and negative 4 x + 8 y = 7
6 x + 2 y = 6 and 7 x + 3 y = 9
3 x minus 4 y = 16 and 2 x + 3 y = 5
The equation which has no solutions is 5 x + 5 y = 10 and 2 x + 2 y = 4
What is equation?
An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
As,
5 x + 5 y = 10 and 2 x + 2 y = 4
a1= 5, b1= 5, c1 = -10
a2= 2, b2= 2, c2 = -4
Now, a1/ a2 = 5/2
b1/ b2= 5/2
c1/ c2= -10/-4 = 5/2
Hence, a1/a2= b1/b2= c1/c2
So, the pair of equation has no solution.

A radio station gave away 192 tickets to a concert. They gave away 5 times as many tickets to listeners as they gave to employees. How many tickets did they give away to employees?
Answer:
Tickets to workers= 32
Step-by-step explanation:
Giving the following information:
Total tickets= 192
They gave away 5 times as many tickets to listeners as they gave to employees.
We will use the rule of 3:
6/6=192
5/6= ? = 192*(5/6) = 160
They gave 160 tickets to listeners.
Tickets to workers= 192 - 160= 32
Prove:
32*5= 160

Oliver has of a gallon of water. He pours all of the water into 6 containers. If he pours the same amount of water into each container, how many gallons of water does Oliver pour into each container?
Answer:
I believe it is 1/3 of a gallon
Step-by-step explanation:
because he pours it into 6 containers (which make each container hold 1/6 of a gallon)
then he pours the same amount again which will make it 2/6 of a gallon and 2/6 simplified is 1/3

the perimeter of the given equilateral triangle is 42 cm find s if it's side length is (3s+2) cm
Answer:
14cm
Step-by-step explanation:
Given parameters:
perimeter of the triangle = 42cm
length of side = (3s + 2)cm
Unknown:
Find the length of each side = ?
Solution:
The perimeter of a body is the sum of all its sides.
In this problem, we have been given an equilateral triangle. For such a triangle, all the sides are equal. So the perimeter is the sum of all the three sides;
(3s + 2) + (3s + 2) + (3s + 2) = 42
9s + 6 = 42
9s = 42 - 6
9s = 36
s = 4;
The length of its sides = 3s + 2
= 3(4) + 2
= 12 + 2
= 14cm
Determine the average rate of change over left curly bracket negative 4 less or equal than x less or equal than 4 bold right curly bracket. Do NOT simplify.
Answer:
{-4≤ x≤ 4}
The average rate of change would be 1 for f(x) = x.
Step-by-step explanation:
Suppose we have a range a≤x≤b, then the average rate of change can be calculated by =f(b) - f(a)/b-a
The given range lies from -4 to 4 as {-4≤ x≤ 4}
The range of this is from -4 to 4.It includes all the numbers ranging from -4 to 4.
The average rate of change of the function is calculated by
= f(4) - f(-4)/4-(-4)
Suppose f(x)= x then f(4)= 4 and f(-4)= -4
Then
4- (-4)/ 4- (-4)
= 8/8= 1
So the average rate of change would be 1.

Answer:
Step-by-step explanation:
Use y=mx+b so do y1-y2 over x2-x1 to get the slope then do y=m(slope)x+b and whatever number you get from doing slope(x-x1) you substitute your x1 with the number and subtract or add to get y=slope + whatever number you have left after you did the inverse on both sides
for example: y=-2x-3.

find the value of x and y. if (x+y,1) =(2,2x-y)
Answer:
x=1/3. y=3/2
Step-by-step explanation:
x+y=2. =>equation 1
2x-y = 1. => equation 2
equation 1 + equation 2,
x+y+(2x-y) = 2-1
x+y+2x-y = 1
3x = 1
x=1/3
plug in value of x in equation 1,
1/2 + y = 2
y= 2 - 1/2
y = 3/2
