I got the exact question so pls hit me up when you find the answer
Step-by-step explanation:
Show that x+y:x-y=3:2
We have,
x+y:x-y=3:2
To prove that, x+ y : x - y = 3:2.
x+y=3
And,
x+y = 2
Adding (1) and (2), we get
x+y+x-y=3+2
⇒2x=5
⇒ x =
Put x = in (1), we get
+y=3
⇒ y=3-=
x+y:x-y=
=3:2
So, x+y:x-y=3:2.

Answer:
x = 2∠IEH = 58°∠IHE = 49°Step-by-step explanation:
a) The diagonals of a parallelogram bisect each other. So, the length of one half is equal to the length of the other half.
IE = IG
2x -2 = 2
x -1 = 1 . . . . . . divide by 2
x = 2 . . . . . . . add 1
__
b) Sides of a parallelogram are parallel, so each diagonal can be considered to be a transversal. Alternate interior angles where the transversal meets parallel lines are congruent. (Essentially, the figure is symmetric about its center, where the diagonals cross.)
∠IGF ≅ ∠IEH = 58°
∠IFG ≅ ∠IHE = 49°

What is the slope of the line shown in the graph?
A 3/2
B) 2/3
C) -3/4
D) -2/3
Answer:
D.
Step-by-step explanation:
y-intercept is (0, 3)
x-intercept is (4.5, 0)
formula to find the slope from two points is
[tex]slope = m = \frac{y2 - y1}{x2 - x1} = \frac{y1 - y2}{x1 - x2} \\ [/tex]
then the slope of the line that crosses (0, 3) & (4.5, 0) is
[tex]m = \frac{3 - 0}{0 - 4.5} = \frac{3}{ - 4.5} = - \frac{3}{ \frac{9}{2} } = - \frac{2}{3} [/tex]

Find the general solution to the equation y(5) - 4y(4) + 4y(3) = 1.
Answer:
y= -1/23
Step-by-step explanation:
The equation y(5)-4y(4)+4y(3)=1 can be solved thus:
Work on brackets first:
5y-16y+12y=1
Add up y values
5y-28y=1
Divide both sides of equation
-23y=1
y=1/-23
Therefore the value of y is -1/23
What is the best unit of measurement for a wasp’s leg?
Answer:
I'd say mm
Step-by-step explanation:
i would choose millimeters because a whole wasp is about 2 centimeters, and there is 10 millimeters in 1 centimeter, so a wasps length is about 20mm, i would think their legs are between 1 and 3 mm long. maybe longer depending on the type of wasp, but i would think to measure in millimeters
write a polynomial function in it's factored form with zeros 5, -1, and 2
Answer:
(x - 5)(x + 1)(x - 2) = 0
Step-by-step explanation:
If a polynomial function has roots a, b, and c, then it is (x - a)(x - b)(x - c).
The roots here are 5, 1, and 2, so the factors are
(x - 5)(x - (1))(x - 2)
The function is:
(x - 5)(x + 1)(x - 2) = 0

Every time Mary bakes a batch of brownies, she uses 1/5 cup of chocolate. If she has 8/10 cup(s) of chocolate remaining, how many batches of brownies can Mary make? Input your answer as a whole number.
giving 35 points if u answer.
Answer:
4 batches
Step-by-step explanation:
just divide 8/10 by 1/5 to get 4 :)
Step-by-step explanation:
Number of cups of chocolate is directly proportional to the number of batches of brownies.
1/5 cups of chocolate = 1 batch of brownies
=> 8/10 cups of chocolate = (8/10) / (1/5)
= 4 batches of brownies.
Hence Mary can make 4 more batches.

6) Tell whether -3 is a solution of the inequality.: y +6<4
A-solution
B-not a solution
Answer:
A - Yes, it's a solution
Answer:
Yes, it is a solution.
Step-by-step explanation:
The reason why it is a solution because when you plug -3 into the y and add -3+6<4, you will get -9<4. -9 is less than 4 because the 9 is a negative. Hope this helps!

The graph shows the number of quarts picked and the amount of money the customer paid.
Part A
What is the constant of proportionality, and what does it mean in this situation?
Answer:
Constant of proportionality k = 3.5
In our case, We can say that Amount of 1 quart is $3.5, and as the number of quarts bought are increased the amount paid is also increased at rate of $3.5.
Step-by-step explanation:
We need to find what is the constant of proportionality, and what does it mean in this situation?
Constant of proportionality can be defined as:
[tex]if\:y\:\alpha \:x\:then\:y=kx[/tex]
Where k is constant of proportionality
It tells that there is constant increase in the value of y.
Looking at the graph,
we get Number of Quarts (x) = 1, Amount Paid (y)= 3.5
so, finding constant of proportionality
[tex]y=kx\\3.5=k(1)\\k=3.5[/tex]
Now, Number of Quarts (x) = 2, Amount Paid (y)=7
so, finding constant of proportionality
[tex]y=kx\\7=k(2)\\k=\frac{7}{2}\\k=3.5[/tex]
So, for any value of x and y, the value of k remains constant i.e 3.5
So, constant of proportionality k = 3.5
In our case, We can say that Amount of 1 quart is $3.5, and as the number of quarts bought are increased the amount paid is also increased at rate of $3.5.

In the formula d=r* t the letters are called
Answer:
Distance = Rate x Time
Step-by-step explanation:
You can use the equivalent formula d = rt which means distance equals rate times time. distance = rate x time. To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. speed = distance/time.
If you deposit $5000 into an account paying 6% annual interest compounded monthly, how long until
there is $8000 in the account?
Answer:
7.85 years which I think rounds to about 7 years and 11 months
Step-by-step explanation:
The formula for compound interest is
[tex]AV=PV*(1+\frac{i}{n})^{t*n}[/tex]
Where AV = Accumulated Value (or Future value)
PV= Present value
i= nominal interest rate
n= number of times compunded in a period (here a period is a year)
t= number of periods (years in this case)
We can plug this numbers in to get
8000=5000*(1+(.06/12))^12x
First we divide by 5000 to get
1.6=(1.005)^12x
We can rewrite this into a logarithim
log₁.₀₀₅1.6=12x
The formatting here is kind of weird but I'm trying to say that log base 1.005 1.6 = 12x
We can compute this and get
94.2355=12x
divide by 12 to get that
x=7.85 Years
