Answer:
not 100% confident but I think this is at least close
Step-by-step explanation:
solve for one variable
1. x-5y=2
x=2+5y
plug this in to another equations and simplify
2. (2+5y)-y=16
2+4y=16
4y=14
y=3.5
this can be plugged in to all other equations to find x
1. x-5(3.5)=2
x-17.5=2
x=19.5
2. x-(3.5)=16
x=19.5
3. 2x-(3.5)=5
2x=8.5
x=4.25
4. x-3(3.5)=4
x-10.5=4
x=14.5

Taylor bought a painting for 1 million yen while in Japan. At the time, exchange rate was 1 dollar to 126 yen. If a friend offers $2,000 dollars for the painting would Taylor profit?
Answer:
No, she would not profit.
Step-by-step explanation:
1 dollar = 126 yen
x = 1000000 yen
1000000 ÷ 126 = $7, 936.51
$2,000 is not enough to cover the value of the painting as Taylor would lose over $5,000. So, she would not profit.
Hope that helps.

b. [4 -1 8 -4]
c. [3 12 15 21]
d. [4 -12 8 -21]
Answer:
(a) [3 -12 15 -21]
Step-by-step explanation:
Given;
3.[ 1 -4 5 -7]
The product of the function is calculated as;
3.[ 1 -4 5 -7] = [1 x 3 -4x3 5x3 -7x3]
= [3 -12 15 -21]
Therefore the correct option is "a" [3 -12 15 -21]

Answer:
V = (x)(10-2x)² . . . . factored form
V = 4x³ -40x² +100x . . . . standard form
Step-by-step explanation:
A square with corners cut out has no volume. It is a plane figure.
__
We presume you are interested in the volume of the open-top box obtained by folding up each "ear" of the cut figure. The length of each side of its square bottom is 10-2x. The depth of the box is x. So, the volume is ...
V = LWH = (10-2x)(10-2x)(x)
V = x(10 -2x)²
_____
The graph shows the volume is a maximum when x = 1 2/3 cm.
In ΔIJK, k = 26 cm, ∠I=135° and ∠J=11°. Find the length of i, to the nearest centimeter.
Answer:
33 cmStep-by-step explanation:
GivenTriangle IJK with:
Side k = 26 cm, ∠I = 135°, ∠J = 11°To findThe length of side iSolutionFind angle K:
∠K = 180° - (135° + 11°) = 34°Use the low of sines to findthe value of i:
i/sin I = k/sin Ki = k sin I / sin Ki = 26 * sin 135° / sin 34° = 33 cm (rounded to the whole number)State the segment that represents the image, based on the information given.
The clockwise rotation of ΔAPG about 90 degree gives ΔCPA.
What is Rotation?Each point in a figure is transformed into a rotation by rotating it a specific amount of degrees around another point.
Given:
We have ΔAPG.
Now, we have to rotate about 90 clockwise rotation.
Then, ΔAPG will overlap on ΔCPA
Hence, the clockwise rotation of ΔAPG about 90 degree gives ΔCPA.
