What is a linear equation?A linear equation in two variable has the general form as y = ax + by + c, where a, b and c are integers and a, b ≠ 0.
It can be represented as a straight line on a graph.
The equation of the given line is y = 2x - 3.
In order to find the point lying on it, consider each of the options one by one as follows,
(a) (2 , 3)
Substitute x = 2 and y = 3 in the given equation to obtain LHS and RHS as,
LHS = y
= 7
RHS = 2x - 3
= 2 × 2 - 3
= 1
Since, LHS ≠ RHS, the given point is not the solution.
(b) (-2, -1)
Substitute x = 2 and y = 3 in the given equation to obtain LHS and RHS as,
LHS = y
= 7
RHS = 2x - 3
= 2 × -1 - 3
= -6
Since, LHS ≠ RHS, the given point is not the solution.
(c) (4, 1)
Substitute x = 2 and y = 3 in the given equation to obtain LHS and RHS as,
LHS = y
= 4
RHS = 2x - 3
= 2 × 1 - 3
= -1
Since, LHS ≠ RHS, the given point is not the solution.
(d) (0, -3)
Substitute x = 2 and y = 3 in the given equation to obtain LHS and RHS as,
LHS = y
= -3
RHS = 2x - 3
= 2 × 0 - 3
= -3
Since, LHS = RHS, the given point is the solution.
Hence, the point (0, -3) is the solution of the given equation.

Enter your answer in the box.
Answer:
702 ft²
Step-by-step explanation:
The total surface area of the prism is the sum of the areas of its 7 faces.
lateral area
The width of each rectangular face is 8 ft. The total length of all of the rectangular faces is equal to the perimeter of the base:
7 ft +5 ft +3 ft +5 ft + 2 ft = 22 ft
So, the rectangular area is ...
A = LW = (8 ft)(22 ft) = 176 ft²
__
base area
The area of each base is equivalent to the area of a 5 ft×7 ft rectangle with a 3 ft×4 ft right triangle cut off one corner. The base area will be ...
A = LW -1/2bh
A = (5 ft)(7 ft) - 1/2(3 ft)(4 ft) = 29 ft²

The width of a rectangular flower shop is 20 feet less than twice the length. The perimeter is more than 70 feet. Which inequality can be used to find a possible length x of the shop in feet?
A. x+ (2x - 20) > 70
B. 2x + 2(2x - 20) > 70
C. x + (x - 20) > 70
D 2x + 2(x - 20) >70
Answer:
what is it
Step-by-step explanation:
The perimeter is represented by the inequality 2x + 2(2x - 20) > 70. Then the correct option is B.
What is the perimeter of the rectangle?Let W be the rectangle's width and L its length. The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be
Perimeter of the rectangle = 2(L + W) units
The width of a rectangular flower shop is 20 feet less than twice the length.
W = 2L - 20
The perimeter is more than 70 feet. Then the inequality is given as,
P < 2(L + W)
70 < 2(L + 2L - 20)
70 < 2L + 2(2L - 20)
Replace L with x, then we have
2x + 2(2x - 20) > 70
The perimeter is represented by the inequality 2x + 2(2x - 20) > 70. Then the correct option is B.

Quadrilateral DEFG has coordinates D (2, 1), E (2, 6), F (5, 6), and G (5, 1). How can quadrilateral DEFG be classified?
Group of answer choices
rhombus but not a square
parallelogram but neither a rhombus nor a rectangle
rectangle but not a square
square
Answer:
Rectangle but not a square
Step-by-step explanation:
Let's start by determining if it's a parallelogram.
The slope of side DE is undefined.
The slope of side EF is 0.
The slope of side FG is undefined.
The slope of side DG is 0.
Thia means we have 2 pairs of opposite parallel sides, meaning DEFG is a rhombus.
Now, let's determine if it's a rectangle. Since the slope of
side DE is undefined and the slope of side EF is 0, sides DE and EF are perpendicular. This means that angle DEF is a right angle, and thus DEFG is a rectangle.
To determine if DEFG is a rhombus, we can find the lengths of adjacent sides DE and EF.
The length of DE is 5.
The length of EF is 3.
Since the pair of consecutive sides (sides DE and EF) aren't congruent, DEFG is not a rhombus.
Since DEFG is not a rhombus, it also cannot be a square.
This means DEFG is a rectangle, but not a square.

f(x)=x2+6x+9f ( x ) = x 2 + 6 x + 9
Answer:
[tex]\large\boxed{\sf f(x) = x^2-6x+9}[/tex]
Step-by-step explanation:
We are here given a graph of a equation and we are interested in finding the equation .
From the given graph we can see that it cuts the x axis at point (3,0) . This graph represents a quadratic function and its two zeroes are 3,3 . We can write the equation using the two zeroes .
Say if the zeroes of the quadratic equation are p and q , then the quadratic equation can be written as ,
[tex]\longrightarrow (x-p)(x-q)=0 [/tex]
And the quadratic function can be written as ,
[tex]\longrightarrow f(x)= k[ (x-p)(x-q)][/tex]
where k is a constant .In this case k = 1 . So we can write the function as ,
[tex]\longrightarrow f(x) = (x-3)(x-3)[/tex]
Distribute ,
[tex]\longrightarrow f(x)= x (x-3)-3(x-3)[/tex]
Simplify by opening the brackets,
[tex]\longrightarrow f(x) = x^2-3x -3x +9 [/tex]
Add like terms,
[tex]\longrightarrow \underline{\underline{f(x) = x^2-6x+9}}[/tex]

Lines AB and CD and are parallel. Find the measures of the three angles in triangle ABF.
Answer: ∠B = 42° ∠A = 23° ∠F = 115°
Step-by-step explanation:
∠B≅∠C alternate interior angles 42°
∠CDF is supplementary to ∠CDE,
so m∠CDF = 23° and ∠FAB≅∠CDF so m∠FAB= 23°
also ∠A ≅ CDE corresponding angles 157° ∠FAB is suplementary to ∠A
so 180 - 157 = 23 gives the m∠FAB
The sum of the angles of a triangle is 180°, so m∠AFB = 180 -(23 +42)
180- 65 = 115 = m∠F

Karla buys t-shirts to promote her local business. She develops the inequality t > 100 for the number of t-shirts she needs to sell in order to make a profit. Answer the following questions. If she is selling each shirt for $15 dollars, how much money did Karla spend to make the t-shirts? How do you know?How much money would Karla have lost if she sells only 90 t-shirts?
Karla spent $1500 to make the shirt and will lose $150 if she sells only 90 t-shirts.
What is an inequality?An inequality is an expression that shows the non equal comparison of two or more numbers and variables.
Let t represent the number of t-shirts she needs to sell in order to make a profit. Since:
t > 100 and the price is $15 per shirt, hence:
Money spent = $15 * 100 = $1500
Money lost in sell 90 shirts = (100 - 90) * 15 = $150
Karla spent $1500 to make the shirt and will lose $150 if she sells only 90 t-shirts.

Arianna and Blair are working on a problem together: Solve x/3 + 8 = -2. Blair thinks the first step is to multiply by 3. Arianna explains that this, not the most efficient way to solve. Explain who is correct and justify your reasoning.
x/3 + 8 = -2
Because x is in a fraction, the most efficient way to solve is to remove the 8 first.
The first step should be to subtract 8 from both sides:
x/3 = -10
Then you would multiply both sides by 3:
x = -30
Blair was correct but Arianna is correct too.
Let's see why :
_________________________________ We're gonna solve it from Blair's method .
[tex] \frac{x}{3} + 8 = - 2 \\ [/tex]
Multiply sides by 3
[tex]x + 24 = - 6[/tex]
Subtract sides minus 24
[tex]x = - 6 - 24[/tex]
[tex]x = - 30[/tex]
_________________________________
The faster way is :
[tex] \frac{x}{3} + 8 = - 2 \\ [/tex]
Subtract sides minus 8
[tex] \frac{x}{3} = - 2 - 8 \\ [/tex]
[tex] \frac{x}{3} = - 10 \\ [/tex]
Multiply sides by 3
[tex]x = - 30[/tex]
It is very easier to calculate -2-8 than -24-6 and also it is very easier to multiply -10 by 3 than multiply 8 by 3 and multiply -2 by 3 and then calculate.
So Arianna is correct.
I think this is the correct answer.
Thanks for watching buddy good luck.

Work out 4/5 - 3/20 - 2/10
Answer:
9/20
Step-by-step explanation:
LCM of 5, 20, and 10 = 20
4/5
= 4/5 x 4/4
= ( 4 x 4 )/( 5 x 4 )
= 16/20
2/10
= ( 2/10 ) x ( 2/2 )
= ( 2 x 2 )/( 10 x 2 )
= 4/20
4/5 - 3/20 - 2/10
= 16/20 - 3/20 - 4/20
= ( 16 - 3 - 4 )/20
= ( 16 - 7 )/20
= 9/20
Answer:
9/20
Step-by-step explanation:
First, you need to find common denominators between all of the fractions.
All of these denominators can be multiplied by a whole number to equal 20.
For 4/5, multiply both the numerator and the denominator by 4 to get 16/20
Leave 3/20 alone
For 2/10, multiply both the numerator and the denominator by 2 to get 4/20
Now you have 16/20 - 3/20 - 4/20
= 9/20
