how i do inequalities
Answer:
Following the steps given below you can solve any inequality.
Step-by-step explanation:
I will give an example and explain you step by step of solving an inequality.
Consider an inequality: [tex]2x+4 > 8[/tex]
In this inequality we need to find the value of x.
Step 1: Write the inequality
[tex]2x+4 > 8[/tex]
Step 2: Subtract 4 on both sides of inequality
[tex]2x-4 > 8-4\\2x>4[/tex]
Step 3: Now, you have divide both sides by 2 to get value of 4
[tex]\frac{2x}{2}>\frac{4}{2}\\x>2[/tex]
So, solving the inequality we find value of x: [tex]x>2[/tex]
Following these steps you can solve any inequality.
I hope it will help you.
At the Gwinnett county fair, each person pays $8.99 for admission (in order to get in) plus $2.50 for each ride. While at the fair, Elian goes on six rides. Which expresion could be used to find the total amount Elian spends?
Answer:
The expression is
[tex]y=8.99+2.5x[/tex]
Step-by-step explanation:
Step one:
given data
cost per person for entry/admission= $8.99
cost per ride= $2.5
we are told that Elian went on six rides
Step two:
let the number of rides be x
the linear function for the total cost at the Gwinnett county fair for each person is
[tex]y=8.99+2.5x[/tex]
for x=6
y=8.99+2.5(6)
y=8.99+15
y=23.99
The total amount Elian spends is $23.99

Write a quadratic equation in standard form with 1 over 2
and 3 as its roots
Answer:
f(x) = 2x² - 7x + 3
Step-by-step explanation:
Given the roots are x = [tex]\frac{1}{2}[/tex] and x = 3, then the corresponding factors are
(x - [tex]\frac{1}{2}[/tex] ) and (x - 3), that is
(2x - 1) and (x - 3)
The equation is then the product of the roots, that is
f(x) = (2x - 1)(x - 3) ← expand factors using FOIL
f(x) = 2x² - 7x + 3 ← in standard form

(0,1) and (-5,7)
Answer:
12
Step-by-step explanation:
[tex]We\ know\ that\ distance\ between\ two\ points\ on\ a\ graph\ is\ given\ by\\\\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\Here,\\x_1=0\\x_2=1\\y_1=-5\\y_2=7\\Substituting\ them\ in\ our\ formula,\ we\ get:\\\sqrt{(1-0)^2+(7-(-5))^2}\\=\sqrt{1+(7+5)^2} \\=\sqrt{1+144}\\=\sqrt{145}\\=12.04\\Hence\ it\ rounds\ off\ to\ 12.\\[/tex]

Write the equation of the line {point-slope form} that
passes through the given points.
(-2, -3) and (2, 5)
What is the equation of this line in slope-intercept form?
y = 3x + 1
y = -3x - 1
y = -1/3x - 1
y = 3x - 1
Answer:
y = -3x - 1
Step-by-step explanation:
-1 is the slope intercept, as you can see where the line goes through the y-axis.
The line is also negative, as it's going down, and the slope is three down (negative) and one over. Since slope is written as y over x (y/x), 3 is y. One, the x, doesn't need to be written because 3 is already a whole number.

Step-by-step explanation:
Adam, Barry, and Charles visited a small farmers market last Saturday. Adam purchased 3 dozen eggs, 1 wheel of cheese, and 5 pounds of potatoes. Barry bought 1 dozen eggs and 10 pounds of potatoes, while Charles purchased 2 dozen eggs and 2 pounds of potatoes. If Adam's bill was $38.25, Barry's $36.50 and Charles' $17.20, how much did a dozen eggs, a wheel of cheese and a pound of potatoes cost?
Answer:
A pound of potato costs $3.10
A dozen egg costs $5.5
A wheel of cheese costs $6.25
Step-by-step explanation:
Represent
- a dozen egg with D
- a wheel of cheese with W
- a pound of potato with P
For Adam:
[tex]3D + W + 5P = 38.25[/tex] ---- (1)
For Barry:
[tex]D + 10P = 36.50[/tex] ---- (2)
For Charles:
[tex]2D + 2P = 17.20[/tex] ---- (3)
Make D the subject in (2)
[tex]D = 36.50 - 10P[/tex]
Substitute 36.50 - 10P for D in (3)
[tex]2(36.50 - 10P) + 2P = 17.20[/tex]
[tex]73 - 20P + 2P = 17.20[/tex]
[tex]73 - 18P= 17.20[/tex]
Collect Like Terms
[tex]- 18P= 17.20 - 73[/tex]
[tex]- 18P= -55.8[/tex]
[tex]18P= 55.8[/tex]
Solve for P
[tex]P = 55.8/18[/tex]
[tex]P = 3.1[/tex]
Substitute 3.1 for P in [tex]D = 36.50 - 10P[/tex]
[tex]D=36.50 - 10 * 3.1[/tex]
[tex]D=36.50 - 31[/tex]
[tex]D=5.5[/tex]
Substitute 3.1 for P and 5.5 for D in [tex]3D + W + 5P = 38.25[/tex]
[tex]3(5.5) + W + 5(3.1) = 38.25[/tex]
[tex]16.5 + W + 15.5 = 38.25[/tex]
Solve for W
[tex]W = 38.25 - 16.5 - 15.5[/tex]
[tex]W = 6.25[/tex]
Raffle tickets were sold for a school fundraiser to parents, teachers, and students. 563 tickets were sold to teachers. 888 more tickets were sold to students than to teachers. 904 tickets were sold to parents
Given :
Raffle tickets were sold for a school fundraiser to parents, teachers, and students. 563 tickets were sold to teachers. 888 more tickets were sold to students than to teachers. 904 tickets were sold to parents.
To Find :
How many tickets were sold to students.
Solution :
Ticket sold to teachers, T = 563 .
Ticket sold to parents, P = 904 .
Let, ticket sold to students are S.
Now, it is given that :
S = T + 904
S = 563 + 904
S = 1467 students
Therefore, tickets sold to students are 1467 .
Hence, this is the required solution.
Please help... it’s about Pythagorean theorem! I attached the image of the question
Answer:
127.28 ft
Step-by-step explanation:
Using the Pythagorean Theorem we have the following:
90^2 + 90^2 = (distance)^2
8,100 + 8,100 = (distance)^2
16,200 = (distance)^2
(distance) = (sq root sign)16, 200 = (sq root sign)25 ∗ 648 = 5 (sq root sign)36 ∗ 18
(distance)^2 = 5 ∗ 6 (sq root sign)18 = 30 (sq root sign)9 ∗ 2 = 3 ∗ 30 (sq root sign)2
(distance)^2 = 90 (sq root sign)2 = 127.28 feet

Explain the pattern you can use to find the product when multiplying a whole number by a power of ten. Will this pattern be the same when multiplying a decimal by a power of ten? Explain with examples.
Answer:
The pattern is the same when multiplying a whole number and a decimal number by a power of ten.
Step-by-step explanation:
The pattern to use when multiplying a whole number by a power of ten can be expressed as follow:
A whole number is a number without a fraction, so let say we choose 12 as a whole number, and let choose 6¹⁰ as a number with the power of ten.
To multiply these two numbers, we get;
= 12 × 6¹⁰
= 12 × 60466176
= 725594112
Now, the pattern to use when multiplying a decimal by a power of ten.
A decimal number is a number that comprises of a whole number and a fraction number that is being by a decimal point.
Let say our decimal number is 1.2 and our number raised to the power of ten is 6¹⁰
Then, To multiply these two numbers, we get;
= 1.2 × 6¹⁰
= 1.2 × 60466176
= 72559411.2
Thus, the pattern is the same when multiplying a whole number and a decimal number by a power of ten.

Edgar has a pen pal who uses the metric system. The pen pal wrote that his dog weighs 20 kilograms. If 1 kilogram is equivalent to 2.2 pounds, about how many pounds does the dog weigh?Required to answer. Single choice.
Answer:
44 pounds
Step-by-step explanation:
We are told that;
1kg = 2.2 pounds.
Now, the pen pal wrote that his dog weighs 20 kilograms.
Thus, the dog's weight in pounds will be gotten by proportion as;
Weight = (20 kg × 2.2 pounds)/1 kg
Weight = 44 pounds
Therefore, the dog weighs 44 pounds
