Answer:

she would have 98.52 left

Step-by-step explanation:

250.00 - 140.00 = 110.00

140.00+8.2% =151.48

250.00 - 151.48 =  98.52

The two angles given are vertical angles which mean they are the same.

x +40 = 60

Subtract 40 from both sides:

x = 20

Answer:

x=20

Step-by-step explanation:

These are verticle angles, meaning the two should equal one another. If one angle is 60, its vertical angle is x+40.

x+40=60

x=20 (subtract 40 from both sides)

Answer:

y=mx+b

Step-by-step explanation:

Answer:

You can see that it also uses the slope. You'll plug in your x1 and y1 along with the slope into the formula. Then you'll evaluate and rewrite it in the slope-intercept form by solving for the y variable. From this, we see that our equation for the trend line is y = (1/3)x + 2, and we are done!

Answer:

55

Step-by-step explanation:

If they're complementary, that means they add up to 90 so:

x + x - 20 = 90

Then, solve.

Answer:

A: 96 B:192 C:288

Step-by-step explanation:

3+2+1=6

Divide 576 by 6 to get 1/6, you will get 96.

so 96 is the area of the dining room.

Multiply 2 times 96, since that would be 2/6.

That would be 192.

So 192 would be the area of the kitchen.

Here's a trick: all you need to do is add 96 and 192 now (or multiply 96 by 3), because that is half of the areas, 3/6.

So 96 times 3 is 288.

The living room is 288.

To check our work, we can add 288 by 96 by 192.

We would end up with 576, which was our original number.

So 288:192:96.

Answer:

GF = 16.25

Step-by-step explanation:

If G is the circumcenter of triangle ABC, AG = 6x + 1, GC = 9x – 11, and BC = 38, find GF.

Step 1

We find x

AG = GC

6x + 1 =9x - 11

Collect like terms

1 + 11 = 9x - 6x

12 = 3x

x = 12/3

x = 4

Step 2

We solve for AG

GC = 9x + 11

GC = 9(4) + 11

GC = 36 + 11

GC = 25

Step 3

Solving for GF, using Pythagoras Theorem

GF² + BG² = GC²

GF² = GC² - BG²

GF = √GC² - BG²

GF = √25² - 19²

GF = √264

GF = 16.248076809

GF = 16.25

Step-by-step explanation:

Answer:

Answer:

Step-by-step explanation:

The zero (root) of a function is any value of the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x-axis.

~~~~~~~~~

f(x) = x³ + 3x² - x - 3

f(-3) = ( - 3 )³ + 3( - 3 )² - ( - 3 ) - 3 = 0

f(-1) = ( - 1 )³ + 3( - 1 )² - ( - 1 ) - 3 = 0

f(1) = ( 1 )² + 3( 1 )² - ( 1 ) - 3 = 0

Answer:

The zeroes of the function are x = -3, x = -1, and x = 1.

Step-by-step explanation:

We are given a polynomial and asked to find the zeroes of the polynomial. Our given polynomial is:

[tex]x^3 + 3x^2 - x - 3[/tex]

The zeroes of a polynomial are the solutions or roots of the function. This is where if the line were graphed, the line would intersect the x-axis at those points (sometimes there will only be one).

This is a cubic polynomial. We can use a factoring technique referred to as grouping, which is most effective when factoring a trinomial with the only satisfaction met is: a > 1.

However, it can also be used when a > 1 is not true.

We can work with an example polynomial first and then work through solving the given polynomial.

An example polynomial would be:

[tex]10x^2 + 8x - 9 = 0[/tex]

In grouping, our main goal is to factor as quickly as possible. If you examine the polynomial, there is no common factor between 10x², 8x, or -9, so we cannot take out a GCF and need to use another factoring technique.

Since a > 1, we can instantly jump to using the grouping factoring technique.

Please note that the parent function for a quadratic is [tex]ax^2 + bx + c = 0[/tex].

To group:

Let's use grouping to solve [tex]x^3 + 3x^2 - x - 3[/tex].

Because we already have four terms, we can skip steps one through three and go straight to step four.

[tex](x^3 + 3x^2)(-x - 3)[/tex]

Now, we need to take the GCF of both parentheses sets. Let's do this with our first set of terms.

Then, we can also do this with our second set of terms.

Because our remaining terms for both sets match, we have grouped our polynomial correctly. Now, let's combine our GCFs into one term and list our common term as the second term.

[tex](x^2-1)(x+3)[/tex]

Now, we can break apart x² - 1 into more factors.

This is the difference of two squares. The formula for the difference of two squares is [tex](a^2-b^2)=(a+b)(a-b)[/tex]

Our perfect squares are every integer in the spectrum of numbers, so 1 is a perfect square. Therefore, x² becomes x and 1 becomes ±1.

Our new terms would therefore be [tex](x+1)(x-1)(x+3)[/tex].

Finally, to find zeroes of a function, x needs to equal something. Therefore, we can set our terms equal to zero and solve for x.

Term 1 (x + 1)

[tex]x + 1 = 0\\\\x + 1 - 1 = 0 - 1\\\\\boxed{x = -1}[/tex]

Term 2 (x - 1)

[tex]x - 1 = 0\\\\x - 1 + 1 = 0 + 1\\\\\boxed{x = 1}[/tex]

Term 3 (x + 3)

[tex]x + 3 = 0\\\\x + 3 - 3 = 0 - 3\\\\\boxed{x = -3}[/tex]

Therefore, our zeroes are listed above. To finalize our answer, we want to list them in increasing order, so this will be most negative to most positive. Therefore, our final answer is x = -3, -1, 1.

Step-by-step explanation:

Answer:

(10,30)

x=10

y=30

Step-by-step explanation:

Looking at the first one we know exactly what y is equal to in terms of x so whenever we need a y in the second equation we can just replace it with 3x which means we have

-.5x+35=3x

Solve for x and get

35=3.5x

10=x

We can then plug this x value into the first equation and solve for y

y=10*3

y=30

our answer is therefore (10,30)

Answer:

x = 10; y = 30

Step-by-step explanation:

1. Plug the 3x from the first equation into the second equation to substitute the y.

-1/2x + 35 = 3x.

2. Subtract 3x from both sides. Then subtract 35 from both sides.

-7/2x = -35

3. Multiply by the reciprocal

x = 10

4. Plug in 10 as the x in the first equation

y = 3(10)

y = 30

Each side equals 11, because 44 / 4 sides = 11

Each side equals 11, area = side x side

area = 11 x 11 = 121

Answer:

∠SVT = 17°   ∠VUT =143°

Step-by-step explanation:

system of Eq.

Eq. 1) 20 + 8x-49 +y =180  ( around one triangle)

8x +y = 209    (Eq 1 simplified)

16x +2y =418  (Eq 1 times 2)

Eq. 2) 40 +8x-49 + 5x+23 +2y =360  (around the whole diamond )

13x + 2y = 346    (Eq 2 simplified)

-(16x +2y = 418 )   ( subtract Eq. 1 from Eq. 2 )

-3x = -72

x = 24°

then  ∠S = 5x+23 = 5(24) +23 = 143°

then ∠U = 8x -49  = 8(24) - 49 = 143°

20 + 143 +y =180

y = 17°

check it :

40 + 34 + 286 = 360° ( around the whole diamond )

Answer:

The new coordinates are (-11, -35)

Step-by-step explanation:

When reflecting across the x-axis, you are just the Y. value. It is the opposite due to the fact that if you're moving something across the horizontal x-axis, it's actually the vertical height changing. So, you just inverse the Y value to its' negative or positive reciprocal.

Answer:

please mark the brainliest❤❤

Step-by-step explanation:

[tex] \frac{6}{21} = \frac{x}{28} = \frac{10}{y} [/tex]

(6×28)÷21=8

(28×10)÷8=35

so x=8

y=35

The value of x is 8 units and y is 35 units.

In geometry, two similar forms are those whose dimensions are identical or have a same ratio but the size or length of their sides differ. Examples include similar triangles, similar rectangles, and similar squares.

Given:

ΔABC ~ ΔDEC

Then, AB/ DE = BC / EC = AC/ DC

So, AC/ DC = AB/ DE

x / 28 = 6 / 21

x / 28 = 2/ 7

x= 8 units

and, BC / EC = AB/ DE

10 / y = 6/21

10/ y = 2/7

2y= 70

y= 35 units

Hence, the value of x is 8 units and y is 35 units.
