Answer:

I think there is an error in the question, I assume it reads:

4x+2y=20

x+3y=50

If not, please make appropriate corrections to the question.

Answer: x=-4, y=18

Step-by-step explanation:

4x+2y=20

Simplify, divide by two,

2x+y=10.....................(1)

x+3y=50....................(2)

Multiply (2) by 2

2x+6y=100 ....................(2a)

Subtract (1) from (2a)

2x+6y - (2x+y) = 100 - 10

5y = 90

y=18..............................(3)

Substitute (3) into (1)

2x+(18)=10

2x = 10-18 =-8

x=-4  ............................(4)

Substitute (3) and (4) into (1) for verification

2x+y = 2(-4)+18 = 18-10 = 10   checks.

Substitute (3) and (4) into (2) for verification

x+3y=-4+3(18) = -4+54 = 50  checks.

Have a nice day!

Answer:

Cos(π/2 - θ) = A

Step-by-step explanation:

We know that:

Sin(θ) = A

And we want to find the value of Cos(π/2 - θ)

Here we can use the cosine relationship:

Cos(a - b) = Cos(a)*Cos(b) + Sin(A)*Sin(B)

Then:

Cos(π/2 - θ) = Cos(π/2)*Cos(θ ) + Sin(π/2)*Sin(θ)

We know that:

Cos(π/2) = 0

Sin(π/2) = 1

Then:

Cos(π/2 - θ) = Cos(π/2)*Cos(θ ) + Sin(π/2)*Sin(θ) = 0*Cos(θ ) + 1*Sin(θ)

                    = 1*Sin(θ) = A

Cos(π/2 - θ) = A

Answer:

To find the absolute value of an negative number, just take away the negative sign

The absolute value of a number can NEVER be negative

Step-by-step explanation:

For example, to find the absolute value of -22, it would be 22, since it is 22 points away from zero. To find the absolute value of -99.9, it would be 99.9.

A negative number is NOT always the absolute value of a number.

For example, the absolute value of 34 is, 34. If you plot it on a number line, it is 34 points away from zero, therefore proving a negative number is NOT always the absolute value of a number.

The absolute value of a number can NEVER be negative.

Answer:

The absolute value of a number is always POSITIVE! To find the absolute value, all you need to do is take away the negative sign!

f(x)=2x^2-8x from x=2 to x=5. Simplify your answer as much.

We need to find [f(b) - f(a)]/(b - a).

Let a = 2

Let b = 5

f(2) = 2(2)^2 - 8(2)

f(2) = 8 - 16

f(2) = -8

We now find f(5).

f(5) = 2(5)^2 - 8(5)

f(5) = 50 - 40

f(5) = 40

[f(5) - f(2)]/(5 - 2)

(40 - (-8))/(3)

(40 + 8)/3

48/3 = 16

The average rate of change is 16.

Answer:

Step-by-step explanation:

You need to remember 2 theorems about a rhombus.

1.  The diagonals of a rhombus bisect each other

2.  The diagonals of a rhombus are perpendicular to each other

In other words, the diagonals of a rhombus are perpendicular bisectors.

BE = 9 and AE = 12

ΔAEB is a right triangle.  So, the Pythagorean theorem says

[tex]9^{2} + 12^{2} = AB^{2}[/tex]

[tex]AB^{2}[/tex] = 81 + 144

       = 225

AB = [tex]\sqrt{225} = 15[/tex] cm

Answer:

Domain: [tex]-6 \leq x \leq 3[/tex]

Range: [tex]-3 \leq x \leq 6[/tex]

Step-by-step explanation:

The domain is the set of real values which can be inputted into a function and produce a real output. In this case, the domain is the following: [tex]-6 \leq x \leq 3[/tex], because this is the set of real values for which the function will produce a real output.

The range is the set of real values which a function outputs when a value from the domain is entered into the function. This is the set of y-values that one can see on the graph, the possible y-values are in between (-3) and (6).

Answer:

1. C=35m?

2.C=700 or $700

Step-by-step explanation:

1. Total Cost= Rate x Number of Months

2. C=35m

Cost=rate x number of months

C=35(20)

C=700 or Total Cost=$700

Answer:

1. c = 35m

2. c = 35 · 20

20 · 35 = $700

Answer:

Answer:

[tex]5.77\ \text{m}[/tex]

[tex]11.54\ \text{m}[/tex]

Step-by-step explanation:

p = Height of pole

h = Length of role

b = Distance between the bottom of the rope and bottom of the pole = 10 m

[tex]\theta[/tex] = Angle between the rope and the ground = [tex]30^{\circ}[/tex]

[tex]\tan\theta=\dfrac{p}{b}\\\Rightarrow p=b\tan\theta\\\Rightarrow p=10\tan30^{\circ}\\\Rightarrow p=5.77\ \text{m}[/tex]

The length of the rope is [tex]5.77\ \text{m}[/tex]

[tex]\cos\theta=\dfrac{b}{h}\\\Rightarrow h=\dfrac{b}{\cos\theta}\\\Rightarrow h=\dfrac{10}{\cos30^{\circ}}\\\Rightarrow h=11.54\ \text{m}[/tex]

The length of the pole is [tex]11.54\ \text{m}[/tex]

$11, 162.78 amount she have in this account if she keeps it for 5 years.

Future value (FV) is a financial concept that provides a monetary worth to an asset depending on future variables such as interest rates or cashflows. An investor may find it valuable to know how much their investment will be worth in five years given a projected rate of return. Future value is calculated by taking the investment value now, applying predicted growth, and estimating what the investment will be in the future.

We have,

P = $10,000

R= 2.2%

T= 5 years

So, Amount after 5 years

= P (1 + r/2[tex])^{2t[/tex]

= 10,000 (1 + 0.011[tex])^{0.022(5)}\\[/tex]

= $11, 162.78
