What is the percent of change from 90 to 18?
I think it decreases 5%
Answer:
80%
Step-by-step explanation:
Nine would equal ten percent, so we double that to get twenty percent, so 18 is twenty percent. Therefore we can determine that it is a 80% decrease.
what’s the distance between 4 and 20
Answer:
16
Step-by-step explanation:
The distance is 16 because when 4 and 20 are on a number line the distance can be measured by subtracting. So 20 minus 4 = 16. :)

Suppose that y varies directly with x
and y = 3 when x = 9. What is y
when x = 18?
y = [ ?
]
I really suck at these problems.
Answer:
y = 6 when x = 18
Step-by-step explanation:
The appropriate formula for this direct proportion is y = kx, where k is the constant of proportionality.
We know y = 3 when x = 9: 3 = k(9)
This yields k = 3/9, or k = 1/3
Then the formula is y = (1/3)x
and when x = 18, y = (1/3)(18) = 6
y = 6 when x = 18

Answer:
The slope is steeper and the line is shifted flatter.
Step-by-step explanation:
I have provided a graph to help illustrate the relationship between these two lines, (The red line is line A which is y = 2x + 4, and the blue line is line B which is y = 4x + 9).
As you can see, the slope does determine the steepness of the lines. This means that line A's slope is going up 2 units and over to the right 1 unit, whereas line B's slope is going up 4 units and to the right 1.
Therefore, if line A is to transform into line B, then its slope will be steeper.
Hope this helps you :)
Also, P.S. I don't know if there are supposed to be more options, so I apologize if flatter does not belong in the second box.

Step-by-stepStep-by-step explanation:
A rectangular field is fully enclosed with 218 meters of fencing. The length of the field is
17 meters longer than the width, w.
The length and width of a rectangular field fully enclosed with 218 metes fencing are 63 meters and 46 meters respectively.
The perimeter of a rectangle is the sum of the whole four sides. Therefore, the perimeter of a rectangle is defined as follows:
perimeter = 2(l + w)where
l = length
w = width
perimeter = 218 meters
The length of the field is 17 meters longer than the width, w. Therefore, the length is defined as follows:
l = 17 + wThe length and the width can be calculated as follows:
218 = 2(l + w)
218 = 2(17 + w + w)
218 = 34 + 4w
218 - 34 = 4w
184 = 4w
divide both sides by 4
w = 184 / 4
w = 46 meters
length = 17 + 46
length = 63 meters

what does i^739 equal? explain how you found your answer.
========================================================
Explanation:
i = sqrt(-1)
Lets list out the first few powers of i
i^0 = 1i^1 = ii^2 = -1i^3 = i*i^2 = i*(-1) = -ii^4 = (i^2)^2 = (-1)^2 = 1By the time we reach the fourth power, we repeat the cycle over again (since i^0 is also equal to 1). The cycle is of length 4, which means we'll divide the exponent over 4 to find the remainder. Ignore the quotient. That remainder will determine if we go for i^0, i^1, i^2 or i^3.
For example, i^5 = i^1 because 5/4 leads to a remainder 1.
Another example: i^6 = i^2 since 6/4 = 1 remainder 2
Again, we only care about the remainder to find out which bin we land on.
-------------
Turning to the question your teacher gave you, we have,
739/4 = 184 remainder 3
So i^739 = i^3 = -i
-i is the final answer--------------
Side notes:
if i^a = i^b, then a-b is a multiple of 4Recall that the divisibility by 4 trick involves looking at the last two digits of the number. So i^739 is identical to i^39.3. You need to hire a taxi.

This diagram shows right rectangular ABCDEFGH. It also shows EB and HB.
Find the length of each diagonal shown in the diagram. If necessary, round your answers to the nearest tenth.
Answer:
17
18.4
Step-by-step explanation:
c² = a² + b²
EB² = 15² + 8²
EB = 17 cm
c² = a² + b²
HB² = HE² + EB²
HB² = 7² + 17²
HB² = 338
HB = 18.4 cm

Solve this system of equations using the Substitution method.
3x + y = -2
y = 2x + 3
Answer:
Step-by-step explanation:
we see that y = -3x-3
substitute that into the other equation to get
-3x-3 = 2x+7
-5x = 10
x = -2
so, y = -3(-2)-3 = 3
check to make sure (-2,3) solves both equations.

Factors of 30:
10 3
15 2
5 6
Using positives or negatives of these numbers you need to find two that'll satisfy the equation
A is known to be 3 and C is known to be 1 because the factors of 3 are only 1 and 3.
After some trial and error we end up with
(3x-5)(x-6)
We know this will work because hen you multiply it out you get
3x^2-18x-5x+30

Type the correct answer in each box. If necessary, use / for the fraction bar(s). Find the solution for this system of equations. 12x 15y = 34 -6x 5y = 3 x = y =.
The value of x and y are 5/6 and 8/5 respectively
Given the systems of equations
12x + 15y = 34 ...................... 1 *1 -6x + 5y = 3 ..................... 2 * 3Solving the equations using the elimination method
12x + 15y = 34
-18x + 15y = 9
Subtract both expressions:
12x-(18x) = 34 - 9
12x+18x = 25
30x = 25
x = 5/6
Substitute x = 5/6 into equation 1 to have:
12x + 15y = 34
12(5/6) + 15y = 34
10 + 15y = 34
15y = 24
y = 8/5
Hence the value of x and y are 5/6 and 8/5 respectively
