9.50×18=171.00
Which equation can be represented by the graph?
Answer:
y+10 = -5(x-3)
Explaination:
Finding the slope intercept form provides you with the line your looking for
here you want to isolate y
y = -5(x-3)-10
and then ditrubute the -5 into the parenthesis
y = -5+15-10
Combine like terms
y = -5x +5
and by looking at this in terms on y=mx+b
the line will intercept the y-axis at (5,0) like the line above shows

The linear equation for this situation is,
⇒ y = 75x
And, There are 75 apple pick in one hour.
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The graph shows how many apples Erin can pick if she ,maintain a constant rate.
Now,
Let two points on the graph are (0, 0) and (1, 75).
So, Slope of the graph (m) = (75 - 0) / (1 - 0)
= 75
Thus, The linear equation is;
⇒ y - y₁ = m (x - x₁)
⇒ y - 0 = 75 (x - 0)
⇒ y = 75x
Where, y is number of apples and x is number of hour.
Thus, Number of apple pick in one hour is;
⇒ y = 75 x 1
⇒ y = 75
So, There are 75 apple pick in one hour.
Therefore, The linear equation for this situation is,
⇒ y = 75x
And, There are 75 apple pick in one hour.

Answer:
y = 50x+25
f(x) = 50x+25
Step-by-step explanation:
Using the slope intercept form of the equation, y = mx+b
where x is the amount per day and b is the flat fee
2 days
125 = 2x+b
5 days
275 = 5x+b
Subtract
275 = 4x+b
125 = 2x+b
---------------------
150 = 3x
Divide by 3
150/3 = 3x/3
50 =x
The cost per day is 50 dollars
y = 50x +b
Using the data for 2 days
125 = 50*2 +b
125 = 100 +b
125-100 = b
b = 25
The equation is y = 50x+25
f(x) = 50x+25
To graph, The x axis is number of days and the y axis is total cost
The number of days starts with 0, which is the y intercept
Let x = 0, y =25
Using the slope, we go 50 up and 1 to the right ( 50 dollars per day)
The next point plotted ins ( 1,50)
Draw a straight line
Answer:
y = 50x+25
f(x) = 50x+25

Which equation is equivalent to the equation 3x - 12 = 24?
A) 15x - 60 = 120
B) 3x = 12
C) 3x = 36
D) x - 4 = 8
E) 12x - 12 = 24
Answer:
C
Step-by-step explanation:
To simplify the equation, all you need to do is add 12 to both sides to cancel out the -12.
The equations that are equivalent to the equation 3x - 12 = 24 are
3x = 36
x - 4 = 8
15x - 60 = 120
Options A, C, and D are correct.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example: x + 2 = 7 is an equation.
We have,
3x - 12 = 24 ____(1)
From (1)
Adding 12 on both sides.
3x = 24 + 12
3x = 36 ____(2)
From (1)
Dividing 3 into both sides.
x - 4 = 8 ____(3)
From (1)
Multiplying 5 into both sides.
5 (3x - 12) = 5 x 24
15x - 60 = 120 ____(4)
From (2), (3), and (4) we see that,
3x = 36
x - 4 = 8
15x - 60 = 120
Thus,
The equations that are equivalent to the equation 3x - 12 = 24 are
3x = 36
x - 4 = 8
15x - 60 = 120
Options A, C, and D are correct.

question 2. the last one
Step-by-step explanation:
Answer:
Step-by-step explanation:
1. 20 a yard and made 100. 100/20=5 yards
20x=100
2. Since they don't give the number of yards they did mow, this would be my answer. I would say half the amount. Since they cut their rates in half, they'll have to cut twice as many to even the amount as before. They would have to cut three - four times as many to make over the original amount. They only have one weekend, so that'll be hard.

A jacket was on sale for 20% off its original price of $60. Now, it is on sale for an additional 10% off its previous sale price. Determine whether each statement is true or false.
Step-by-step explanation:
The question is incomplete, here is the complete one
A jacket was on sale for 20% off its original price of $60. Now, it is on sale for an additional 10% off its previous sale price. Determine whether each statement is true or false. The jacket is now 40% off its original price. True or false The jacket now costs $48.00. True or false The jacket is now 72% of its original price. True or false The jacket now costs $43.20. True or false
Step one:
given
original price= $60
discount =20% of 60
discount = 20/100*60
discount = 0.2*60
discount = $12
selling price= 60-12= $48
Added price= 10% off $48
Added price= 10/100 *48
Added price= 0.1 *48
Added price= $4.8
new price= 4.8-48=$43.2
the new price of the jacket is $43.2
1. The jacket is now 40% off its original price
40/100*60=$24-----False
2. The jacket now costs $48.00-----False
3. The jacket is now 72% of its original price= 72/100*60=$43.2----True
4. The jacket now costs $43.20------True

he is correct because the transformation is a translation and under the translation the image and preimage are congruent.
the measure of the sides are preserved, and the peasure of the angles are preserved so if all the corsponding sides and angles are congruent the hexagons are congruent too

OMG PLEASE HELP!!! NEED WITHIN FEW HOURS!! The diagram shows three circles with radii r=10 cm. The centers also form the vertices of an equilateral triangle.
Answer: 16.205 cm²
It takes some time, but it's not impossible!
Step-by-step explanation:
Find the area of the triangle, then subtract the area of the three sectors.
The three sectors are each 60° so they add to 180° which is equivalent to half the area of one circle.
The area of the triangle is one half base times height. To find the height of the triangle, use the Pythagorean Theorem to get the length of the perpendicular bisector.
a² + b² = c² .
C is the side length, 20cm. (the length of two radii) B is half the side length 10cm. A is the "altitude" or height we need to find.
a² + 10² = 20²
a² + 100 = 400 . a² = 400-100
a² = 300
a = √300 a ≈ 17.3205
Area of triangle: A= bh/2
A = (20 × 173.205)/2
Triangle Total Area ≈ 173.205
To the area of the circle, use the equation A = πr²
A = 3.14 × 10²
A = 3.14 × 100
Circle Total Area = 314 cm².
You could take 1/6 of that, and then multiply by 3, or just take half
Area of sectors= 157 cm²
Triangle Area - Sectors Area = Blue shape Area
173.205 - 157 ≈ 16.205 cm²
