here is an inequality: 2x+5>50. explain the steps you would use to solve the inequality for x. what would the graph look like
Answer:
Step-by-step explanation: 2 plus 5
7 <50
Answer:
x = 22.5
Step-by-step explanation:
2x + 5 > 50.
We do inverse operations sooo:
2x + 5 - 5 > 50 - 5.
50 - 5 = 45.
Then we do 2x ÷ 2 and 45 ÷ 2.
45 ÷ 2 = 22.5.
To check our answer to see if its right we do 22.5 x 2 which equals 45. Then we do 45 + 5 which equals 50. So the sign is wrong it should be greater than or equal to.
brainliest answer . Help please answer and pls don't answer if you don't understand .
Answer:
1/2
Step-by-step explanation:
We do change in y over change in x
Formula for Rate of Change on Slope
y2-y1/x2-x1
For Y
We use coordinate (-2, -4)
-4--2
= -2 - -4
= 2
For X
We use coordinate (0, -4)
0 -- 4
= 0 + 4
= 4
Now we put y over x to find the rate of change in slope
2/4, simplified would be 1/2

What is arithmetic progression?A series in which the differences between each pair of following words are the same is known as an arithmetic progression.An arithmetic progression is a series in which every phrase—aside from the initial term—is created by multiplying the preceding term by a predetermined amount.given:
12, 13, 14, ......111.
first term, a= 12
d= 13-12= 1
[tex]a_n[/tex] = 11
Now,
[tex]a_n = a+ (n-1)d\\[/tex]
111 = 12 + (n-1) 1
111-12= n-1
n-1 = 99
n= 100

If x (x+y) = 27 and y (x+y) = 54, what is the value of (x+y)^2?
Answer:
9x^2
Step-by-step explanation:
It is given that:
x ( x + y ) = 27
If one manipulates the equation, by dividing by x, they get:
x + y = 27/x
It is also given that:
y ( x + y ) = 54
Again, manipulate the equation, only this time, divide by y,
x + y = 54/y
It is obvious that;
x + y = x + y
Yet this was proven;
x + y = 27/x
x + y = 54/y
Therefore, the following has to be true;
27/x = 54/y
To sove the proportion, use cross products;
27/x = 54/y
54x = 27y
Inverse operations:
54x = 27y
/27 /27
y = 2x
Substitute;
(x + y)
y = 2x
= (x + 2x)
= 3x
Now solve:
(3x)^2
9x^2

Answer:
0; (0, 0); 144; (3, 144)
Step-by-step explanation:
Y = distance (m)
X = time (hr)
X = 48x
If a car travels for 0 hours, it will travel __ mile(s).
y = 48x
Plug in 0 hours for x (time in hours)
y = 48(0)
Any number mutliplied by 0 equals 0
y = 0
If a car travels for 0 hours, it will travel 0 miles. This means it will pass through the point (0, 0).
(0, 0) limits our options to graphs B and D
Car travels 144 miles in 3 hours
To find how many miles it travels in 1 hour, divide 144 miles by 3 hours
144 ÷ 3 = 48
In 1 hour, a car travels 48 miles
If 48 × 3 = 144, then 48 × 4 = ?
48 × 4 = 192
When looking at graph D, there are 4 lines above 0
Counting by 48, it perfectly fits 192 by the fourth line
From (0, 0), if we move 3 units to the right we can find the third vertical line intersecting
Since the lines are counted by 48 and we are looking at the third line: 48 × 3 = 144
Use the slope to move 3 units to the right of the origin and 144 unit(s) up to the find the point (3, 144) that can be used to graph the relationship

A circle has a diameter of 20 ft. What is the diameter? *
Since the question provided the diameter instead of radius, the diameter is 20 feet
Answer: well the diameter would be 20ft. If you meant to ask for the circumference then its 62.857ft
Step-by-step explanation:
Diameter of a circle is 20 feet.
Hence it's Radius = 20/2 = 10 ft
We know circumference = 2πr
Circumference = 2 × 22/7 × 10 ft
Circumference = 44 × 10/7= 440/7
Circumference = 62.857 ft
