what does mrs freeman pay for the meal
Answers
Answer:
Lin's father pay for the meal is $18.19
Step-by-step explanation:
Given:
Lin’s father is paying for a $20 meal.
He has a 15%-off coupon for the meal.
After the discount, a 7% sales tax is applied.
Now, to get the amount Lin's father pay for meal.
So, we deduct the 15% discount first:
$20 - 15% of $20.
Then, adding 7% sales tax:
$17 + 7% of $17
Therefore, Lin's father pay for the meal is $18.19.

y = 3(x - 1)² + 9
y = 3x² - 7x +2
y = (x + 3)(2x -1)
y = (x - 3)²
Answers
Answer:
The second answer is in standard form of equation
x = 12 − y
2x + 3y = 29
Answers
Bring the variables to one side and the constants to the other side of the equal sign. Remember if you bring anything to the other side it’s sign has to change:
x + y = 12
2x + 3y = 29
Now multiply a variable on the top equation so that it will be equal with the variable on the second:
3x + 3y = 36
2x + 3y = 29
Now subtract the equations which gets you:
x = 7
So we know what the x is, now we have to substitute the x in an equation we created; we’ll go with x + y = 12:
x + y = 12
= 7 + y = 12
Now bring the variable to one side and constants to the other like we did before (remember, the sign must change if the constant or variable is moved to different sides of the equal sign):
y = 12 - 7, which would equal y = 5.
So our answer would be:
( x, y ) = ( 7, 5 )
Hope this helps have an awesome day!

No, they are the same triangles
Step-by-step explanation:
They both have a side length of 3 and 5 and an angle that measures 60 degrees. The triangles are just flipped in different directions.
If they were to draw an additional triangle that would make it seem different, they could expand the angle and make it obtuse to get a triangle with 1 wide corner.

A brick of marble weighs 2,268 grams and has the following dimensions:
length 25 cm, height 12 cm, and width 28 mm. What is the approximate
density of the marble? Round to the nearest tenth.
Type your numerical answer below.
density of marble = _(blank)
g
cm3
Answers
Answer:
Below in bold.
Step-by-step explanation:
Density = mass / volume
Mass = 2268 g.
Width of the brick = 28 mm = 2.8 cm.
Volume = 25 * 12 * 2.8 = 840 cm^3
So the density = 2268/840
= 2.7 g/cm^3.

You are traveling in a car. Your speed is 30 miles per hour. What is your speed in feet per minute?
Answers
Answer:
.5
Step-by-step explanation:
30 miles a hour divide by 60 so your going half a mile a minute
Your speed in feet per minute is 2640 ft/min.
What is unit rate?A unit rate means a rate for one of something.
Given that, Your rate of speed is 30 miles for every 1 hour
We know, 1 mile = 5280 feet
Therefore, 30 miles = 30x5280 = 158400 feet
That means, you are travelling 158400 feet for every hour
In an hour, there are 60 minutes,
Therefore, you are travelling 158400 feet in every 60 minutes.
In 60 minutes = 158400 feet
In 1 minute = 158400/60 = 2640 feet
That means you are travelling 2640 feet in every 1 minute.
Hence, your speed in feet per minute is 2640 ft/min.

Someone please help asap!!! It’s due in 45 minutes, how am I supposed to know where to shade when doing these?
Answers
Answer:
If you want to know the process on how to graph and shade, start by graphing the inequalities. Assume that the inequality signs are just =, so the equation is y=mx+b. Let's use 1) as an example. When the sign is < or >, it's a dotted line. If the sign is ≥ or ≤, it's a solid line. Once you're done graphing the inequalities, choose a random coordinate on the graph. Let's use (0,0). Now, plug in the x- and y-value into the equations. 0<-6(0)+3 and 0≤0-2. Simplify it to get 0<3 and 0≤-2. Because the inequality is true for y<-6x+3, you would shade the side of the graph that includes (0,0). Because the inequality isn't true for y≤-x-2, you would shade the side of the graph that doesn't include (0,0). The shaded parts of both inequalities should overlap somewhere and that's the area you need to officially shade.

Step-by-step explanation:
4x^2 - 16 is the difference of two squares, a case in which there is a simple formula to remember: a^2 - b^2 = (a - b)(a + b)
4x^2 - 16 = (2x - 4)(2x + 4)
