Jane is solving the equasion -2x + 4 = 18. She tells her partner that they should add two to both sides first since that is the inverse of -2. Did Jane start this equation correctly? Explain your reasoning
Answer:
No
Step-by-step explanation:
Given
- 2x + 4 = 18
note the inverse of - 2 is - [tex]\frac{1}{2}[/tex] not - 2
However , the first step is to isolate the term in x by subtracting 4 from both sides.
- 2x = 18 - 4 = 14 ( divide both sides by - 2 )
x = - 7

A dance academy charges $24 per class and a one time registration fee of $15. A student paid a total of $687 to the academy. Find the number of classes the student took.
Answer:
The student took 28 classes
Step-by-step explanation:
What I did was minus $15 from the $687 total, cause $15 is only a one time registration fee, then 687-15=672, so then I divided 672 by the cost per class, so $24, 672 divided by 24 equals to 28, so the student took 28 classes.

6 tenths times 8(please help)
Answer:
24/5 or 4.8
Step-by-step explanation:
This would be 6/10 multiplied by 8 making it 48/10 and if you simplify that you will get 24/5.
Answer:
4.8
Step-by-step explanation:
6 tenths can be written like this: 0.6
If you were to pretend the 0.6 was a six..
6*8=48
There actually is a decimal point and you must move it back to the left one place because there was one before the six

From 1985 through 1995, the yearly gross farrm revenue (in millions) in the United States can be modeled by the function R(t)=-t^2+7t+159 and the yearly farm cost (in millions) in the United States can be modeled by the function c(t)=t^2+131 where t is the number of years since 1985. Write a new function, P(t), that models the yearly profit after 1985
The profit function is simply the difference between the revenue function and the cost function. The profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]
Given that:
[tex]R(t) = t^2 + 7t + 159[/tex]
[tex]c(t) = t^2 + 131[/tex]
The profit function P(t) is calculated as follows:
[tex]P(t) = R(t) - c(t)[/tex]
So, we have:
[tex]P(t) = t^2 + 7t + 159 - (t^2 + 131)[/tex]
Open brackets
[tex]P(t) = t^2 + 7t + 159 - t^2 - 131[/tex]
Collect like terms
[tex]P(t) = t^2- t^2 + 7t + 159 - 131[/tex]
[tex]P(t) = 7t + 28[/tex]
Hence, the profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]

There are 21 apples,28 pears and 49 oranges. These are to be arranged in heaps containing the same number of fruits. Find the greatest number of fruits possible to keep in each heap. How many heaps are formed by this arrangement?
Answer:
greatest no. of fruits possible to keep in each heap is 7
no. of heaps is 14
Step-by-step explanation:
21 apples
28 pears
49 oranges.
[tex]28 \div 21[/tex]quotient will be 1 and 7 remainder
[tex]21 \div 7[/tex]
quotient will be 3 and 0 remainder
[tex]49 \div 7[/tex]
quotient will be 7 and 0 remainder
hence, the greatest number of fruits is 7
Now,no. of heaps formed to keep fruits
Apple = 21
Pear = 28
Orange =49
Now, 21+28+49 = 98
Then, one heap can store can 7 fruits
Then,let the no. of heaps be x
x= 98÷7
x=14
Hence, no. of heaps = 14
Find the area of a rectangular ground which is 14 1/2 m long and 10 2/3 m wide.
Answer:

Step-by-step explanation:
14 1/2 x 10 2/3
First, make the mixed numbers into improper fractions:
29/2 x 32/3
Simlify by cross cancelling if you can:
29/1 x 16/3
Then, multiply:
29/1 x 16/3 = 29 x 16/1 x 3 = 464/3
Finally, turn the new improper fraction into a simplified mixed number:
464/3 = 154 2/3
The area is 154 2/3 m²

Which products result in a perfect square trinomial?
During a 12-hour period, the
temperature dropped 48º.
How many degrees did the
temperature drop each hour?
Answer:
4 degrees every hour
Step-by-step explanation:
Since it was 48 degrees over a total of 12 hours we can do:
48 / 12 = 4 degrees.
It may be presented as -4 degrees since it is dropping in tempature therefore making it negative.
Write f(x) = 2x2 – 44x + 185 in vertex form.
To write f(x) = 2x2 – 44x + 185, factor out
from the first two terms.
Next, form a perfect square trinomial keeping the value of the function equivalent:
f(x) = 2(x2 – 22x + 121) + 185 – 242
The function written in vertex form is f(x) =
(x –
)2 +
.
Answer:
Step-by-step explanation:
[tex]f(x)=2x^2-44x+185\\\\=2(x^2-2*11*x)+185\\\\=2(x^2-2*11*x+11^2)+185-2*121\\\\\boxed{f(x)=2(x-11)^2-57}\\\\vertex\ is\ (11,-57)[/tex]
Answer:
f(x) = 2(x - 11)² - 57
Step-by-step explanation:
Given
f(x) = 2x² - 44x + 185 ( factor out 2 from the first two terms )
f(x) = 2(x² - 22x) + 185
To complete the square
add/ subtract ( half the coefficient of the x- term )² to x² - 22x
f(x) = 2(x² + 2(- 11)x + 121 - 121 ) + 185
= 2(x - 11)² + 2(- 121) + 185
= 2(x - 11)² - 242 + 185
f(x) = 2(x - 11)² - 57 ← in vertex form
How is making a perpendicular bisector different to making an angle bisector
Answer and Step-by-step explanation:
When making a perpendicular line, you take 2 points on a straight line.
- You put the compass on the two points, making marks above and below to be able to draw the line.
When making an angle bisector line, you use the angle and 2 points to make a straight line that will bisect the angle.
- You put the compass on the angle, making an arc from the two lines that join to make the angle. Then, you put your compass on where the arc meets the lines, and make a mark, which you then draw a line through.
