The solution of equations are one solution, infinitely many solutions, one solution and no solution.
We are given that;
The four equations
Now,
To determine whether an equation has no solution, one solution, or infinitely many solutions, we can try to solve for the variable and see what happens.
Let's apply this method to each equation:
a. 8p + 1 = 4p + 2
4p + 1 = 2
Subtracting 1 from both sides, we get:
4p = 1
p = 1/4
This is a consistent result, so the equation has one solution: p = 1/4.
b. -6p + 7 = 7 - 6p
Adding 6p to both sides, we get:
7 = 7
This is an identity, so the equation has infinitely many solutions. Any value of p will satisfy the equation.
c. p + 9 = 2p - 3
Subtracting p from both sides, we get:
9 = p - 3
Adding 3 to both sides, we get:
12 = p
This is a consistent result, so the equation has one solution: p = 12.
d. 5p + 3 = 5p - 1
Subtracting 5p from both sides, we get:
3 = -1
This is a contradiction, so the equation has no solution.
Therefore, by the equation answer will be one solution, infinitely many solutions, one solution and no solution.

The perimeter of the base of a square pyramid is 40 feet. The slant height of the pyramid is 12 feet. Find the surface area of the pyramid.
SHOW WORK
Answers
9514 1404 393
Answer:
340 ft^2
Step-by-step explanation:
The length of one side is 1/4 of the perimeter, so is 10 ft.
The area of the base is the square of the length of the side:
base area = (10 ft)^2 = 100 ft^2
__
The lateral area is the area of four triangles, each with a base of 10 ft and a height of 12 ft.
lateral area = 4(1/2)(10 ft)(12 ft) = 240 ft^2
__
The total surface area is the sum of the base area and the lateral area:
surface area = base area + lateral area
surface area = (100 ft^2) +(240 ft^2) = 340 ft^2

Answers
Answer:
RS = 47 units
Step-by-step explanation:
The midsegment is half the sum of the parallel bases, that is
3x + 5 = [tex]\frac{1}{2}[/tex] ( 2x + 15 + 6x - 37)
3x + 5 = [tex]\frac{1}{2}[/tex] (8x - 22) = 4x - 11 ( subtract 4x from both sides )
- x + 5 = - 11 ( subtract 5 from both sides )
- x = - 16 ( multiply both sides by - 1 )
x = 16
Thus
RS = 2x + 15 = 2(16) + 15 = 32 + 15 = 47

A linear function follows a constant rate of change Here we see x moves by 4 units and that y decreases by 4 units then suddenly changes to 6 units hence 13 Is Not A functionFor 12, it is a function because it follows a consistent rate of change which is x or one unit of change.Answer:
12) The function is linear.
13) This function is not linear.
Step-by-step explanation:
13) A linear functions equation must be in y = mx + b form
When you graph the table there is no y = mx + b equation that makes a line that passes through all the points.

Step-by-step explanation:
You have to solve for x by simplifying both sides of the equation and then isolating the variable
3(x+2)= 2x+14
Distributive Property
3x+6=2x+14
Isolate the variable
3x+6-6=2x+14-6 which is 3x=2x+8

Pedro drives the same route to work on Monday through Friday. His route includes one traffic light. According to the local traffic department, there is a 55% chance that the light will be red when he arrives at the intersection on a randomly selected workday. Suppose we choose 10 of Pedro's workdays at random and let Y = the number of times that the light is red.
Answers
Answer:
6 days
Step-by-step explanation:
Given
The proportion can be represented as:
[tex]p = 55\%[/tex]
And the number of days can be represented as:
[tex]n = 10[/tex]
Required
Determine the expected number of times, the light is red
To do this, we simply multiply the proportion by the number of days:
[tex]Y = n * p[/tex]
Substitute values for n and p
[tex]Y = 10 * 55\%[/tex]
Convert percentage to decimal
[tex]Y = 10 * 0.55[/tex]
[tex]Y = 5.5[/tex]
Approximate
[tex]Y = 6[/tex]
Hence, the expected number of days is 6 days

Answers
Answer:
95°
Step-by-step explanation:
Well first draw a parallel to p, let's say r
so we have that
[tex]\angle 2+\angle3=\angle1[/tex]
and
[tex]\angle y=148\\\\\angle x +63=180\\\\\angle x=117[/tex]
so now by internal angles of parallels we know that
[tex]\angle x +\angle 2 = 180\\\\\angle y +\angle 3 = 180[/tex]
which is
[tex]117+\angle 2 = 180\\\\\longrightarrow \angle 2 = 63\\\\148+\angle 3 = 180\\\\\longrightarrow \angle3=32[/tex]
so
[tex]\angle 1 = 63+32\\\\\angle 1 = 95[/tex]
