Y = -5/3x +3 and Y = 1/3x -3

Mathematics
1 answer:
ratelena [41]2 years ago
7 0

Answer:

(X , Y) = (3 , -2)

Step-by-step explanation:

Assuming this is solved via the comparison method ...

<em>-5/3x+3 = 1/3x-3</em> which gets you x = 3

Now, substitute the given value of x into the equation, y=1/3x-3(-3)

Solve for Y, Y=-2

<em>The possible solution of the system is the ordered pair (X , Y)</em>

<em>(3 , -2)</em>

Answer:

V_{composite\: figure} =678.24\: in^3

Step-by-step explanation:

  • For a single cylinder:

  • radius (r) = 3 in (Given)

  • height (h) = 8 in (Given)

  • It is given that: all the three cylinders are identical, means their radii and heights are equal.

  • Thus, the volume of composite figure will be equal to three times the volume of single cylinder.

  • \implies V_{composite\: figure} =3(\pi r^2 h)

  • \implies V_{composite\: figure} =3(3.14\times  (3)^2 \times 8)

  • \implies V_{composite\: figure} =3(226.08)

  • \implies V_{composite\: figure} =678.24\: in^3

Supposed charity received a donation of $23.9 million. If this represents 54% of the charity donated funds what is the total amo
Tanzania [10]

Total amount of funds is $44.26 million.

Step-by-step explanation:

Given,

Donation received = $23.9 million

As it represents 54% of charity.

Let,

Total amount = x

Therefore,

54% of x = 23.9 million

\frac{54}{100}*x=23.9\\0.54x=23.9

Dividing both sides by 0.54

\frac{0.54x}{0.54}=\frac{23.9}{0.54}\\x=\$44.26\ millions

Total amount of funds is $44.26 million.

Write an equivalent expression for 88 +16x +8 . If x=4,is the solution to both expressions the same.
Firlakuza [10]
You can find an equivalent expression for this by combining like terms.
The terms are 88, 16x, and 8.
The like terms are 88 and 8.
To combine them, add them together.
88 + 8 = 96
The equivalent expression would be 16x + 96.
This means 16x + 96 is the same as <span>88 + 16x + 8.

Since they are equivalent, that means they are equal, or the same.
So no matter what x is, they will both be equal to the same thing, so their solutions will be the same.

Answers:
Equivalent Expression: 16x + 96
Yes, both expressions will have the same solutions if x = 4.

Hope this helps!</span>

Parallelogram ABCD has diagonal segments AC and BD that intersect at E. if BE is ( x + 8) and ED is (5 x), find the length of BD
Virty [35]

Answer:

BD = 20 units

Step-by-step explanation:

Given that,

Parallelogram ABCD has diagonal segments AC and BD that intersect at E.

BE = (x+8) and ED = 5x

We need to find the length of BD.

BD = BE + ED ...(1)

We know that the diagonals of a parallelogram bisects each other. It means,

BE = ED

x+8 = 5x

8 = 5x - x

8 = 4x

x = 2

BE = (x+8)

= (2+8)

= 10

ED = 5x

= 5(2)

= 10

Put the values in equation (1).

BD = 10 + 10

= 20 units

Hence, the length of BD is 20 units.
