Solve the system of equations 4x + 3y = -25

7x - 3y = -52

Answers

Answer:

x = -7

y = 1

Step-by-step explanation:

Solve by Substitution :

// Solve equation [2] for the variable x

[2] 7x = 3y - 52

[2] x = 3y/7 - 52/7

// Plug this in for variable x in equation [1]

[1] 4•(3y/7-52/7) + 3y = -25

[1] 33y/7 = 33/7

[1] 33y = 33

// Solve equation [1] for the variable y

[1] 33y = 33

[1] y = 1

// By now we know this much :

x = 3y/7-52/7

y = 1

// Use the y value to solve for x

x = (3/7)(1)-52/7 = -7

Solution :

{x,y} = {-7,1}

A rental car company charges $42.72 per day to rent a car and $0.10 for every mile driven. Zoey wants to rent a car, knowing that:
She plans to drive 200 miles.
She has at most $350 to spend.

Which inequality can be used to determine xx, the maximum number of days Zoey can afford to rent for while staying within her budget?

Answers

Answer:

7 Days

Step-by-step explanation:

Miles cost:

$0.10 * 200 = $20


Daily Cost

Her budget at this point is $330 because $350 - $20 (the miles)

$330 / 42.72  = Roughly 7.72

Therefore Zoey can drive for 7 days before her budget runs out.

write an equation of a line passing through the point (-4,11) and perpendicular to the line 4x + 5y = -45

Answers

Answer:

y = 5/4x - 6

Step-by-step explanation:

First, put 4x + 5y= -45​ in y = mx + b form

4x + 5y= -45​

5y = -4x - 45

y = -4/5x - 9

So, the slope is -4/5. Perpendicular lines have a opposite reciprocal slope, so the line's slope will be 5/4 right so to find the equation of the perpendicular line in this question, plug in the slope and given point into y = mx + b, and solve for b

y = mx + b

-11 = 5/4(-4) + b

-11 = -5 + b

-6 = b

so you should Plug in b and the slope into y = mx + b

y = 5/4x - 6

So, the equation is y = 5/4x - 6

What is the exact area of the following circle?

Answers

Answer:

56.25 pi  cm^2

Step-by-step explanation:

To find the area of the circle,

we use the formula

A = pi r^2, where r is the radius

We know the diameter is 15 so we can find the  radius from

r = d/2  where d is the diameter

r = 15/2

A = pi ( 15/2) ^2

A = pi ( 225/4)

A = 56.25 pi  cm^2

Answer:

2nd option

› 56.25π cm²

Step-by-step explanation:

we know ,

area of circle is πr²

so,

given,

diameter,d = 15cm

radius,r = d/2 = 15/2 = 7.5 cm

so,

area = πr²

= (7.5×7.5)π

= 56.25π cm²

WILL GIVE BRAINLIEST The mass of a substance, which follows a continuous exponential growth model, is being studied in a lab. A sample increases continuously at a relative rate of 7% per day. Find the mass of the sample after four days if there were 123 grams of the substance present at the beginning of the study.

Do not round any intermediate computations, and round your answer to the nearest tenth.

Answers

Then we know that we originally had 38 grams of the substance, the rate of growth is 18%, and that the time it was allowed to grow is 6 days. Then we have using the exponential growth model that the amount of the sample after 6 days will be S = P e^rt where P is the initial sample amount, r is the rate of growth, t is the time, and S is the final sample amount. S = 38 e^ .18*6 = 38 e ^ 1.08 = 111.8978 Thus if there were 38 grams of the substance present at the beginning of the study the mass of the sample would be 111.8978 grams after the study.

Answers:ST = 23RU = 8SV = 5SU = 10

====================================================

Explanation:

Focus on triangles SVT and UVT.

They are congruent triangles due to the fact that SV = VU and VT = VT. From there we can use the LL (leg leg) theorem for right triangles to prove them congruent.

Since the triangles are the same, just mirrored, this means ST = UT = 23.

-----------------------

Following similar reasoning as the previous section, we can prove triangle RVU = triangle RVS.

Therefore, RS = RU = 8

-----------------------

SV = VU = 5 because RT bisects SU.

Bisect means to cut in half. The two smaller pieces are equal.

-----------------------

SU = SV + VU = 5+5 = 10

Refer to the segment addition postulate.

Answer:

ST=23

RU=8

SV=5

SU=10

Step-by-step explanation:

RT bisects the whole quadrilateral, so a line on one side will be the same length as the line on the opposite side of RT. So:

1. ST=UT, UT=23, so ST=23

2. RU=RS, RS=8, so RU=8

3. SV=VU, VU=5, so SV=5

4. SU=2*SV, 5*2=10, so SU=10

If you still have no clue, just imagine the points R, S, T, and the lines connecting them (this will make a triangle). Then reflect the triangle across line RT, and name the new S point U (the new triangle still has the same line measures) . Make a line from S to U and make a point V from where RT and SU meet. This will make the figure in the picture.

Have a nice day! :)

Your response should be a paragraph of 57 sentences.[1] After earning a few dollars working on my brother-in law's farm near Portage [Wisconsin], I set off on the first of my long lonely excursions, botanising in glorious freedom around the Great Lakes and wandering through innumerable tamarac and arbor-vitae swamps, and forests of maple, basswood, ash, elm, balsam, fir, pine, spruce, hemlock, rejoicing in their bound wealth and strength and beauty, climbing the trees, revelling in their flowers and fruit like bees in beds of goldenrods, glorying in the fresh cool beauty and charm of the bog and meadow heathworts, grasses, carices, ferns, mosses, liverworts displayed in boundless profusion.[2] The rarest and most beautiful of the flowering plants I discovered on this first grand excursion was Calypso borealis (the Hider of the North). I had been fording streams more and more difficult to cross and wading bogs and swamps that seemed more and more extensive and more difficult to force one's way through. Entering one of these great tamarac and arbor-vitae swamps one morning, holding a general though very crooked course by compass, struggling through tangled drooping branches and over and under broad heaps of fallen trees, I began to fear that I would not be able to reach dry ground before dark, and therefore would have to pass the night in the swamp and began, faint and hungry, to plan a nest of branches on one of the largest trees or windfalls like a monkey's nest, or eagle's, or Indian's in the flooded forests of the Orinoco described by Humboldt.What creates tone in a piece of writing?
