A linear inequality is an inequality that involves a linear function.
Examples of linear inequality are: 2x + y < 5, x + y > 2, y - x
A linear equation is represented as:
[tex]\mathbf{y = mx + b}[/tex]
A linear inequality can be gotten from a linear equation by changing the equality sign to any of the following inequality sign: >, < !=, >= and <=
So, examples of linear inequality are:
2x + y < 5, x + y > 2, y - x >= 2, 12x + 4y <= 20 and 6y - 7x > 1

because it says she is taller so you add both
Height of Amy who is 5 cm taller than Jack is 1.83 meters.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Jack is 1.78 m tall and Amy is 5 cm taller than Jack.
Therefore, The sum of the height of Jack and 5 cm more is the height of
Amy.
Therefore,
178 cm + 5 cm = 183 cm is the height of Amy. (1m = 100 cm)
So, 183 cm is equal to 1,83 meters.

The prove is explained below:
Step-by-step explanation:
The computation is given below:
Here we needed two equations
Let us assume x = 0.555 --------------- (1)
Now if multiplied it by 10 to the both sides
So, it would be
10x = 5.555............(2)
Now deduct equation 1 from equation 2 in order to remove the recurring decimals
(10x - x) = (5.5555 - 0.5555 )
9x = 5 (divided the both sides by 9 )
So x = 5 by 9
If Holly gets 14 % off a shirt , what percent of the original price will still pay
Answer:
Holly will still pay 86% of the original price.
Step-by-step explanation:
Given
Holly gets 14% off a shirt, soDiscount = 14%To determine
What percent of the original price will still pay.
All we need is to subtract the percentage of discount from 100.
i.e.
100 - Discount = 100 - 14 = 86%
The amount left over would be what remains of the original price after Holly gets 14 % off a shirt.
Thus, Holly will still pay 86% of the original price.

If f(x)=2x−2 and g(x)=x2−8x+19, then f(x)=g(x) for what values of x?
x=−1 and x=−4
x=−3 and x=−7
x=1 and x=4
x=3 and x=7
Answer:
D) x =3 and x =7
Step-by-step explanation:
Step(i):-
Given function f(x) = 2x -2
g(x) = x² - 8x +19
Given that f(x) = g(x)
⇒ 2x -2 = x² - 8x +19
⇒ x² - 8x +19 -2x +2 =0
⇒ x² -10x +21 =0
Step(ii):-
The factors are x² -10x +21 =0
⇒ x² - 7x - 3x +21 =0
⇒ x( x-7) -3( x-7) =0
⇒ (x-3)(x-7) =0
x =3 and x =7

Write the equation of a line going through the points (4,2) and (7,-3).
Answer:
Equation of the straight line passing through the point ( 4,2) and (7,-3) is
5 x + 4y - 28=0
Step-by-step explanation:
Step(i):-
Given points are ( 4,2 0 and ( 7,-3)
Slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{-3-2}{7-4} = \frac{-5}{4}[/tex]
Step(ii):-
Equation of the straight line passing through the point ( 4,2) and
having slope m = [tex]\frac{-5}{4}[/tex]
y - y₁ = m( x- x₁ )
[tex]y - 2 = \frac{-5}{4} ( x-4)[/tex]
4( y -2) = -5( x-4)
4 y - 8 = - 5x +20
5x +4y -8 -20=0
5 x + 4y - 28=0
Final answer:-
Equation of the straight line passing through the point ( 4,2) and (7,-3) is

Two pairs of socks and a pair of slippers cost $30. Five pairs of socks and a pair of slippers cost $42. Let u
represent the cost of a pair of socks and let y represent the cost of a pair of slippers.
Identify the system of equations that represents the situation and identify the solution to the system of equation.
Answer: See explanation
Step-by-step explanation:
The information given in the question can be turned into an equation as:
2u + y = 30 ........ i
5u + y = 42 ........ ii
Subtract i from ii
3u = 12
u = 12/3 = 4
A pair of socks cost $4
Since 2u + y = 30
2(4) + y = 30
8 + y = 30
y = 30 - 8 = 22
A pair of slippers cost $22
$35 bill before tax
tax:5.8%
Tip:21%
Answer:
If tip goes only on amount but not on tax: $44.38
If tip goes on total including tax: $44.81
Step-by-step explanation:
If the tip is applied to the price before tax, then we need to add 5.8% and 21% of $35 to $35.
tax + tip = 5.8% + 21% = 26.8%
100% + 26.8% = 126.8% = 1.268
1.268 * $35 = $44.38
If the tip is applied to the price plus tax, then we calculate the amount including tax first, then we add the 21% tip based on that price.
Bill before tax: $35
Add 5.8% tax: 1.058 * $35 = $37.03
Add tip to the amount including tax: 1.21 * $37.03 = $44.81
Can anyone give me the awnser?
Answer:
Step-by-step explanation:
You want to reverse the algebra and solve for y. First you want to subtract the 'a' to both sides.
x - a = -2by^2
Divide by -1 on both sides
-x + a = 2by^2
Divide by 2b on both sides
(-x + a)/2b = y^2
Take the square root of both sides
[tex]\sqrt{(-x+a)/2b}=y[/tex]

Emilia and Sydney went out to dinner. The bill came to $48. They want to leave a 20% tip and
split the bill. How much do they each pay?
$9.60
$28.80
$57.60
$68.00
Answer:
Option B is correct.
Step-by-step explanation:
Total bill = $48
Tip = 20%
Amount of tip = 20% of 48
Amount = [tex]\frac{20}{100}*48[/tex]
Amount = 0.2 * 48
Amount = $9.60
Total bill with tip = 48 + 9.60 = $57.60
Dividing by 2 as they are spliting the bill.
Each pays = [tex]\frac{57.60}{2}=28.80[/tex]
Therefore,
Option B is correct.
