Answer:
y= -x+2
Step-by-step explanation:
Using the equation, y = mx+b, you know you have to find the slope. Find the slope using two coordinate points, (-2,4) and (0,2).
Subtract 2-4/0+2 - the answer is -1. Your slope is -1 and the y axis is given so the equation is y=-x+2

Answer:
C
Step-by-step explanation:
Its the best possible answer
Answer:
C
Step-by-step explanation:
The answer is C. All you need to do is check each graph and see if (0,45) (1,70) (2,95) (3,120) are plotted on the graph correctly. And C is correct because each point is plotted on there correctly.
3) Solve these problems that have more than one answer.
A) Mary read 3 times the amount of books as Carey over the summer. Carey read twice as
many books as Barry. If the students read 405 books combined, how many more books did
Mary read than Barry?
----
Answer:
225
Step-by-step explanation:
Mary = 3x (3 times Carey)
Carey = x
Barry = x/2 (Because Carey read twice as many as Barry, it means he read half the amount Carey did)
3x + x + x/2 = 405
4x + x/2 = 405
8x/2 + x/2 (treat these as fractions) = 405
9x/2 = 405
9x = 810 (cross multiply)
x = 90
Mary = 3(90) 270
Carey = 90
Barry = 90/2 45
Mary - Barry
270 - 45 = 225

The mayor knows the area needed for a flower garden in the park. She wants the base to be a certain length. How can she determine the necessary height to get the correct area of the flower garden? Explain.
Answer:
Answer:The formula for the area of a parallelogram is A = bh, and the formula for area of a triangle is A = 1/2bh. Since a triangle is half of the area of a parallelogram with the same base and height, the only difference in the formula is 1/2.
Step-by-step explanation:
Maria would determine the height by dividing the area of the garden by the base
From the question, she has the area and the base.
Also, the garden has the shape of a parallelogram
The area of a parallelogram is the product of the base and the height.
So, when the area is divided by the base, she gets the height

Cheryl, Rita and four of their friends go to a movie and share a 48-ounce bag of popcorn equally and three 48 inch licorice laces equally write a ratio comparing the number of ounces of popcorn to the number of friends. then write a unit rate comparing the lenght of licorice lace for each person.
Answer:
Ratio of 48:5 and 28.8 inches of licorice per friend
Step-by-step explanation:
Ratio: Rita AND 4 of her friends go to the movie, meaning there would be 5 people. All 5 of them decide to share a 48 0unce bag of popcorn. The number problem is asking you to create a ratio comparing the number of ounces of popcorn (48) to the number of friends (5). Therefore, your ratio would be 48:5
Unit rate: Once again, there are 5 people there. Those 5 friends would like to share three 48inch long peices of licorice. The question is asking you to decide how many inches of licorice each friend gets. The first step would be to see how many inches in total we have by multiplying 48*3. That is 144 inches of licorice. The next step would be to divide the number of inches by the number of friends. That would be 144/5 and give you 28.8. The last step is to write out your unit rate. 28.8 inches of licorice per friend.

Answer:
15+24t
Step-by-step explanation:
First, I copied the expression down. Then, I used PEMDAS, so I multiplied 5x3. That left 15 + t(24). I just gave the variable to 24, making 24 t's coefficient. So, the simplified answer would be 15 + 24t.

There are five ways to colour the centre square.
Suppose we colour the left hand side. Since the colours of the strip are symmetrical, the number to colour the right hand side is 1.
For the left part where there are 14 squares, let's consider the most adjacent square to the centre. There are four ways to colour that square since it cannot have the same colour as the centre square.
The same goes with the other squares remaining.
So, the answer is 5×4^14.
Answer: so I think like count each square up to 5 and u will have 4 left just try make it even ig ✌️

Answer:
a) x= 42 , b) x=(16)/(9) , c) x=60
Step-by-step explanation:
a)
Divide 48 by 8 - 48 / 8 = 6Multiply 6 by 7 - 6 x 7 = 42You get x = 42b)
Flip (9)/(2)…(i.e. reciprocal)Multiply 8 and 2 - 8 x 2 = 16 You get x = (16)/(9)c)

Katie, Elizabeth, and Siobhan volunteer at the
hospital. In a week, Katie volunteers 3 hours
more than Elizabeth does and Siobhan
volunteers 1 hour less than Elizabeth. Over
3 weeks, the number of hours Katie
volunteers is equal to the sum of Elizabeth’s
and Siobhan’s volunteer hours in 3 weeks.
Complete the table to find out how many
hours each person volunteers each week.
Answer: 3(x+3) = 3X + 3(x-1)
3x + 9 = 3x + 3x - 3
3x + 9 = 6x - 3
0 = 6x - 3 - 3x - 9
0 = 3x - 12
12 = 3x

Step-by-step explanation:
We need to get rid of parentheses in this term.
All the negative factors will change sign.
In our example, we have only one negative factor.
The sign of the term will change, since there is an odd number of negative factors.
We can reduce this fraction by dividing both numerator and denominator by a common numeric factors.

c) Cube root of a perfect cube number ending with three zeroes ends
with one zero.
d) Cube root of a negative number may be positive.
Answer:
b is the correct answer
Step-by-step explanation:
(ii) A perfect cube does not end with two zeros. (iii) If square of a number ends with 5, then its cube ends with 25. (iv) There is no perfect cube which ends with 8.Cube roots of negative numbers are always negative.
Use complete sentences to describe why √-1 ≠ -√1
Well let's say that to compare these two numbers, we have to start with the definition first.
Definition
[tex] \displaystyle \large{ {y}^{2} = x} \\ \displaystyle \large{ y = \pm \sqrt{x} }[/tex]
Looks like we can use any x-values right? Nope.
The value of x only applies to any positive real numbers for one reason.
As we know, any numbers time itself will result in positive. No matter the negative or positive.
Definition II
[tex] \displaystyle \large{ {a}^{2} = a \times a = |b| }[/tex]
Where b is the result from a×a. Let's see an example.
Examples
[tex] \displaystyle \large{ {2}^{2} = 2 \times 2 = 4} \\ \displaystyle \large{ {( - 2)}^{2} = ( - 2) \times ( - 2) = | - 4| = 4}[/tex]
So basically, their counterpart or opposite still gives same value.
Then you may have a question, where does √-1 come from?
It comes from this equation:
[tex] \displaystyle \large{ {y}^{2} = - 1}[/tex]
When we solve the quadratic equation in this like form, we square both sides to get rid of the square.
[tex] \displaystyle \large{ \sqrt{ {y}^{2} } = \sqrt{ - 1} }[/tex]
Then where does plus-minus come from? It comes from one of Absolute Value propety.
Absolute Value Property I
[tex] \displaystyle \large{ \sqrt{ {x}^{2} } = |x| }[/tex]
Solving absolute value always gives the plus-minus. Therefore...
[tex] \displaystyle \large{ y = \pm \sqrt{ - 1} }[/tex]
Then we have the square root of -1 in negative and positive. But something is not right.
As I said, any numbers time itself of numbers squared will only result in positive. So how does the equation of y^2 = -1 make sense? Simple, it doesn't.
Because why would any numbers squared result in negative? Therefore, √-1 does not exist in a real number system.
Then we have another number which is -√1. This one is simple.
It is one of the solution from the equation y^2 = 1.
[tex] \displaystyle \large{ {y}^{2} = 1} \\ \displaystyle \large{ \sqrt{ {y}^{2} } = \sqrt{1} } \\ \displaystyle \large{ y = \pm \sqrt{1} }[/tex]
We ignore the +√1 but focus on -√1 instead. Of course, we know that numbers squared itself will result in positive. Since 1 is positive then we can say that these solutions exist in real number.
Conclusion
So what is the different? The different between two numbers is that √-1 does not exist in a real number system since any squared numbers only result in positive while -√1 is one of the solution from y^2 = 1 and exists in a real number system.
Answer:
Therefore [tex]\sqrt{1} \neq -\sqrt{1}[/tex]
Step-by-step explanation:
[tex]\sqrt{-1} \\[/tex] cannot be calculated as no two identical numbers that are multiplid could give -1. However - [tex]\sqrt{1}[/tex] means -1 x [tex]\sqrt{1}[/tex] = -1 x 1 = -1 . Therefore [tex]\sqrt{1} \neq -\sqrt{1}[/tex]
