Answers

Answer 1

Answer: 6x+3y=12

x=-1/2y+2

Step-by-step explanation:

step 1: add -3y to both sides

6x+3y+-3y=12+-3y

6x=-3y+12

step 2: divide both sides by 6

6x/6=-3y+12/6

Answer 2

Answer:

y = 6 and x = -1.

Step-by-step explanation:

It's normally useful for me to rewrite the equation so they match. I'm using the substitution method.

First find out what "y" equals (I'm using the second equation):

Add 8 to both sides:

y - 8 = 2x

  +8    +8

y = 2x + 8

Plug this into the previous equation.

6x + 3(2x + 8) = 12

Distribute first:

3(2x + 8)

3 * 2x = 6x

3 * 8 = 24

6x + 24

Rewrite the equation:

6x + 6x + 24 = 12

Find liked terms.

6x + 6x + 24 = 12

They are liked terms so combined them: 6x + 6x = 12x.

Rewrite the equation again:

12x + 24 = 12

Solve for "x".

Subtract 24 on both sides.

12x + 24 = 12

      -24   -24

12x = -12

Divide 12 to get x by itself.

12x = -12

    12

x = -1

Plug x into the second equation to find y.

y - 8 = 2(-1)

y - 8 = -2

Add 8 to both sides.

y - 8 = -2

  +8   +8

  y = 6

The answers are y = 6 and x = -1.

Mr. and Mrs. Sanchez want to invest money for their
child's college education. They have decided to invest
$2000 initially. If the investment is in an account that
earns 8% annual interest, compounded yearly for 10
years, how much will their investment be worth at the
end of the 10th year? (Hint: $2000 is ao, think about a
as the value of the account at end of the 1st year.)

Answers

The total amount accrued, principal plus interest, with compound interest on a principal of $2,000.00 at a rate of 8% per year compounded 1 times per year over 10 years is $4,317.85.

Given Data

Initial Amount = $2000

Annual interest rate = 8%

Time = 10 years

A = P + I where

P (principal) = $2,000.00

I (interest) = $2,317.85

Calculation Steps:

First, convert R as a percent to r as a decimal

r = R/100

r = 8/100

r = 0.08 rate per year,

Then solve the equation for A

A = P(1 + r/n)^nt

A = 2,000.00(1 + 0.08/1)(1)(10)

A = 2,000.00(1 + 0.08)(10)

A = $4,317.85

B. Sketch the reflection on the coordinate plane.

Answers

Answer:

A' = (-1, 6)

B' = (-2, 1).

C' = (-5, 2).

Step-by-step explanation:

Reflection  over the y-axis--->  (a, b) transforms to (-a, b).

So  A (1, 6) --->   A' (-1, 6).

The coordinates will have the same y-value but all x-values will become negative. So for example if A is (3,0), A’ would be (-3,0) and so on for B’ and C’

What is an exponent?

Let a be the initial value and x be the power of the exponent function and b be the increasing factor.

The exponent is given as

From the graph, at x = 0, the value of the function is 4. Then we have

[tex]\rm \\4= a \ e^{b\times 0}\\[/tex]

a = 4

Then the exponential equation is given as,

[tex]\rm y = 4e^{bx}[/tex]

From the graph, at x = 1, the value of the function is 2.426. Then we have

[tex]\rm 2.426 = 4 e ^b \\\\e^b = 0.6065[/tex]

Take natural log on both sides, then we have

b = - 0.50

Then the exponential equation is given as,

[tex]\rm y = 4 \ e^{-0.50x}[/tex]

The function that could produce the graph will be [tex]\rm y = 4 \ e^{-0.50x}[/tex]. Then the correct option is B.

In a recent year, the annual salary of the governor of new York was $179,00. During the same year, the annual salary of the governor of Tennessee was $94,000 less. Write and solve an equation to find the annual salary of the governor of Tennessee (y) in that year.

Answers

Answer:

$85,000

Step-by-step explanation:

Given that, the annual salary of the governor of New York was $179,000.

Let $y be the annual salary of the governor of Tennesse during the same year.

As the annual salary of the governor of Tennessee was $94,000 less than the annual salary of the governor of New York.

So, the annual salary of the governor of Tennesse,

[tex]y=179000-94000[/tex]

Hence, the annual salary of the governor of Tennesse during the same year was $85,000.

Both plans cost the same when 50 texts are sent

Step-by-step explanation:

Let

x ---->the number of texts

y ----> the total cost in dollars

we know that

The linear equation in slope intercept form is equal to

where

m is the slope or unit rate

b is the y-intercept or initial value

we have that

Emilia’s plan (Red line)

The slope is

The y-intercept is

substitute

----> equation A

Hiroto’s plan (Blue line)

The slope is

The y-intercept is

substitute

----> equation B

The solution of the system of equations A and B is the point of intersection both graphs

The intersection point is given

The intersection point is (50,22.5)

That means----> For x=50 texts, the cost is equal in both plans

Verify each statement

case a) Hiroto’s plan costs more than Emilia’s plan when more than 50 texts are sent

The statement is false

Because

Emilia’s plan costs more than Hiroto’s plan when more than 50 texts are sent

Verify

For x=100 texts ----> 100 > 50

Emilia's plans

Hiroto's plans

case b) Both plans cost the same when 22 texts are sent

The statement is false

Because

Both plans cost the same when 50 texts are sent

case c) Emilia’s plan costs more than Hiroto’s plan when more than 22 texts are sent.

The statement is false

Because

Emilia’s plan costs more than Hiroto’s plan when more than 50 texts are sent

Answers

Step-by-step explanation:

First of all, [tex]\frac{-1}{-2}[/tex] is equal to [tex]\frac{1}{2}[/tex] because a negative divided by a negative is positive. So now we've got [tex]2a^\frac{1}{2}[/tex]. Well, a fractional exponent, when simplified, is a root. For example, [tex]x^\frac{1}{3}[/tex] is equal to [tex]\sqrt[3]{x}[/tex], and [tex]x^\frac{2}{5}[/tex] is equal to [tex]\sqrt[5]{x^2}[/tex].

Now this is where people make mistakes. Remember, [tex]2a^\frac{1}{2}[/tex] is really [tex]2*a^\frac{1}{2}[/tex], which means only a is raised to the exponent. We would only raise 2a to the power of [tex]\frac{1}{2}[/tex] if our term was [tex](2a)^\frac{1}{2}[/tex]. But since our term is [tex]2*a^\frac{1}{2}[/tex] we raise a to the power of [tex]\frac{1}{2}[/tex] which is the same as [tex]\sqrt[2]{a}[/tex] or just [tex]\sqrt{a}[/tex]. Then we multiply that result by 2 and we have [tex]2\sqrt{a}[/tex] which is fully simplified.

Need help finding the missing side of each triangle?

Answers

This is a right triangle. Use the Pythagorean theorem to solve:

x^2 + 5.8^2 = 15.6^2

x^2 + 33.64 = 243.36

Subtract 33.64 from both sides:

x^2 = 209.72

Take the square root of both sides:

x = 14.48171

Round to 1 decimal place:

x = 14.5 in.

Answer:

x = 14.5 in

Step-by-step explanation:

There is something called pythagoras' theorem. It states that

a^2 + b^2 = c^2,

a, b and c being sides of a right-angled triangle.

C is always the hypotenuse and a and b are any of the other two.

(The hypotenuse is always the longest side, and always opposite to the right angle, which is always the biggest angle of a right-angled triangle.)

So here we know two sides, the hypotenuse and another side. Let's substitute them into the formula:

5.8^2 + x^2 = 15.6^2

x^2 = 15.6^2 - 5.8^2

x^2 = 243.36 - 33.64

x^2 = 209.72

x = sqr209.72

x = 7sqr107/5 = 14.48171261 in

= 14.5 in (if rounded to 3 significant figures)

You could use a shortcut to do all this and find the answer more quickly:

a^2 = c^2 - b^2 or b^2 = c^2 - a^2

also:

a = sqr(c^2 - b^2)

x = Sqr(15.6^2 - 5.8^2)

= 14.5 in

A person invests 7000 dollars in a bank. The bank pays 5.5% interest compounded monthly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 13200 dollars?

Answers

The number of years it will take the person to leave the money in the bank until it reaches 13200 dollars is 2.9 years.

To calculate the time the person must leave the money in the bank until the money reaches 13200 dollars, we use the formula of compound interest below.

What is compound interest?

This is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods.

Formula:

A = P(1 + r/100)ⁿ................ Equation 1

Where:

A = AmountP = Principler = Raten = Time.

From the question,

Given:

P = 7000 dollarsr = 5.5%  componded monthlyA = 13200 dollars

Substitute these values into equation 1 and solve for n

13200 = 7000(1+(5.5×12)/100)ⁿ(1+(5.5×12)/100)ⁿ = 13200/7000(  1.66)ⁿ = 1.886n = 2.9 years

Hence, The number of years it will take the person to leave the money in the bank until it reaches 13200 dollars is 2.9 years.
