Find the values of x and y in triangle ABCD

Answer:

4 solutions counting any possible multiplicity

Step-by-step explanation:

Recall that if one considers the Complex Number System, a polynomial has as many solutions (including multiplicity) as its degree.

So in this case, where we are considering a polynomial of order 4 Notice that the term [tex]-\,33\,x^4[/tex], is in reality the leading term (term with the highest power of the variable) of this polynomial.

Therefore, in the Complex Number System, this polynomial would have 4 solutions.

Answer:

x = 17

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

5x-18 + 4x+45 = 180

Combine like terms

9x +27 = 180

Subtract 27 from each side

9x+27-27 =180-27

9x =153

Divide by 9

9x/9 = 153/9

x =17

Answer:

51 liters of fuel is needed more to fill the tank

Step-by-step explanation:

When the gauge is full, the volume of fuel in the tank is 68 liters.

Now it is 1/4 full.

The amount of fuel it has when it is 1/4 full would be 1/4 * 68 = 17 liters

Now, we need to know how many more liters of fuel until the tank is full.

What we just need to do here is to subtract the volume when it is quarter full from the volume when it is full.

That would be 68 liters - 17 liters = 51 liters

Answer:

I think it is 49.5

Step-by-step explanation:

i say this because you add the 2 percentages together then you divide it by how many dice there are and in this case it is 2. so 66 plus 33 =99

and 99 divided by 2 is 49.5

Answer: B) increasing for x < -4/3 and x > 4/3

                   decreasing for -4/3 < x < 4/3

Step-by-step explanation:

Graph the equation and follow the curve from left to right. If you are going up, it is increasing. If you are going down, it is decreasing.

Refer to the image below. Red is increasing. Blue is decreasing.

The vertices are at: x = -4/3 and x = 4/3

Answer:

the answer is C

Answer:

The answer is C.

Step-by-step explanation:

We are given: [tex]\frac{3+2i}{1-5i}[/tex]. To find the quotient, simplify it. To do that, multiply by the conjugate of the denominator.

The conjugate of [tex]1-5i[/tex] is [tex]1+5i.[/tex]\

Thus, we have:

[tex]\frac{3+2i}{1-5i} \cdot\frac{1+5i}{1+5i} =\frac{3+15i+2i+10i^2}{1-25i^2}[/tex]

Recall that [tex]i^2[/tex] is simply -1.

Thus, we have:

[tex]\frac{3+17i-10}{1-(-25)}=\frac{-7+17i}{26}[/tex]

We can split this:

[tex]-\frac{7}{26}+\frac{17}{26}i[/tex]

Answer:

x = -1

Step-by-step explanation:

4x + 4 = 0

Subtract 4 on both sides.

4x = 0 - 4

4x = -4

Divide both sides by 4.

x = -4/4

x = -1

Answer:

So the value of x is -1

Step-by-step explanation:

4x+4=0

Subtracting 4 on both sides

4x+4-4=0-4

4x=-4

Dividing 4 on both sides

x=-4/4

x=-1

Answer:

Barney got 14 dimes and Betty got 10 quarters.

Step-by-step explanation:

Since there are only dimes and quarters in the parking meter, the total money must be equal to:

[tex]0.1*dimes + 0.25*quarters = 3.9[/tex]

Since Barney got all the dimes and he has four more coins than Betty, then the number of dimes is:

[tex]dimes = quarters + 4[/tex]

Applying the second expression on the first, we have:

[tex]0.1*(quarters + 4) + 0.25*quarters = 3.9\\0.1*quarters + 0.4 + 0.25*quarters = 3.9\\0.35*quarters = 3.9 - 0.4\\0.35*quarters = 3.5\\quarters = \frac{3.5}{0.35} = 10[/tex]

[tex]dimes = quarters + 4 = 10 + 4 = 14[/tex]

Barney got 14 dimes and Betty got 10 quarters.

Answer:

The zeroes of a polynomial is the value of x when the polynomial is set to 0.

We can write x² - 2x - 8 = 0. This factors to (x - 4)(x + 2) = 0 and using Zero Product Property the solutions are x = 4, x = -2.

Answer:

Step-by-step explanation:

The compound interest expression is given as

[tex]A= P(1+r)^t[/tex]

Given data

Principal P=  $2500

Rate r= 8.25%

Time t = 11 years

Substituting into the expression we can find the final amount A

[tex]A= 2500(1+0.0825)^1^1\\A= 2500(1.0825)^1^1\\\\A= 2500*2.3917\\A= 5979.25[/tex]

Answer:

8.25

Step-by-step explanation:

To solve, you need to create a system of equations.  You will need two variables since you have two numbers.  Create your equations based on the descriptions given in the problem.

The difference of two numbers is 4.

x - y = 4

The sum of the two number is -7.

x + y = -7

Your system of equations is

x - y = 4

x + y = -7

You can solve systems of equations through either substitution or elimination.  You will get the right answer either way.  I will use substitution since that is my preference.

Rearrange the first equation so that it is equal to x.

x - y = 4

x = 4 + y

Plug this x-value into the x in the second equation.  Solve for y.

x + y = -7

(4 + y) + y = -7

4 + 2y = -7

2y = -11

y = -11/2

Use the y-value to solve for x.  You can plug it into either equation and get the right answer.  I will use the first equation.

x - y = 4

x - (-11/2) = 4

x + 11/2 = 4

x = -3/2

Now you have both of the numbers.  Multiply to find the product.

-11/2 × -3/2 = 33/4 = 8.25

The answer is 8.25.

Answer:

For an nth term U(n) = a + ( n - 1)d

n = number of terms

a = first term

d = common difference

a = -9

d = -3--9 = -3+9 = 6

U(n) = -9 + (n - 1)6

That's option A.

Answer:

Yes, in fact Bill exceeded his target by £2,200.

Step-by-step explanation:

Cost of the laptops = 50 x 400

= 20,000

Sold 40 at 30% profit

(40 x 400) x 1.30

= 20,800

Sold 10 at 15% profit

(15 x 400) x 1.15

= 6900

Total sales value

= 20800 + 6900 = 27,700

Bill's total sales are greater than his target, that is, £25,400>£25,000. So, we can say that Bill reached his target.

Note: Profit and loss are always calculated on C.P.

Bill buys 50 laptops for £400 each.

∴ His C.P. of each laptop = £400.

He sells them in two parts,

Part 1:

He sells 40 laptops at 30% profit on each laptop.

∴ Profit on each laptop = 30% of C.P. = 30% of £400 = £(0.3*400) = £120

∴ S.P. of each laptop = C.P. + Profit = £400 + £120 = £520

Total sales 1 = Number of laptops * S.P. of each = 40*£520 = £20,800.

Part 2:

He sells 10 laptops at 15% profit on each laptop.

∴ Profit on each laptop = 15% of C.P. = 15% of £400 = £(0.15*400) = £60

∴ S.P. of each laptop = C.P. + Profit = £400 + £60 = £460

Total sales 2 = Number of laptops * S.P. of each = 10*£460 = £4,600.

Bill's total sales after both parts = Total sales 1 + Total sales 2

or, Bill's sales = £20,800 + £4,600 = £25,400.

Since Bill's total sales are greater than his target, that is, £25,400>£25,000. So, we can say that Bill reached his target.

Option A on edge nuity

Answer:

(x1,y1)=(−2,2)

(x2,y2)=(0,−2)

Use the slope formula:

m= y2−y1 /x2−x1

= −2−2 /0−−2

= −4 /2

=−2

Answer:

m=−2 This is the slope

So,the slope intercept form for 2 points is y-y1=m(x-x1)   m=slope  

y-y1=m(x=x1)

y-2=-2(x-(-2)     ( - and - is +) So,the final equation is:

y-2=-2(x+2)

Answer: There were 78 red apples at the party.

Step-by-step explanation:

This situation can be represented by the equation  

x + 3x + 2(3x) = 130    where x is the number of green apples, 3x is the number of  yellow apples and 2(3x) is the number  of red apples.

Now solve for x

x +3x +2(3x) =130

4x + 6x = 130

10x  = 130

x =  13  

Now we know that x is 13 so put it into the expression for red apples and solve for the actual number of red apples.

2 * (3*13)  = ?

2 * 39 = 78
