Answer: y = 8x + 9

Step-by-step explanation: Descartes begins with only $9.00, so 9 is the y-intercept. He makes $8.00 every hour, so that is the slope.

y = mx + b

m is the slope, and b is the y-intercept.

y=8x + 9

The expression that represents the given situation is y = $49.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it isgiven that,

Descartes has Money = $9

Each hour earning = $8

Total time of work = 5 hours

So, total money earned in 5 hours = 8*5 = $40

Let y be the total money Descartes has.

So total money Descartes has = Money + total money earned in 5 hours

⇒ y = $9 + $40

⇒ y = $49

This is the required expression for the present situation.

Thus, The expression that represents the given situation is y = $49.

Answer:

literature most commonly refers to works of the creative imagination, including poetry, drama, fiction, nonfiction, and in some instances, journalism, and song.

If the sum of a number and two is tripled, the result is five less than twice the number, the number is - 11

Let the given number be x,

the number, x is added with 2 and then it is tripled which means       (x + 2)*3 is equal to five less than two times of that number which is 2x - 5

3(x + 2) = 2x - 5

3x + 6 = 2x - 5

3x - 2x = - 5 + (-6)

x = - 11

Therefore, If the sum of a number and two is tripled, the result is five less than twice the number, the number is - 11

The solution to the given quadratic equation using the completing the square method is t = -5/2 ±√29/4

Given the quadratic equation expressed as;

t^2+5t−1=0

Add 1 to both sides

t^2+5t−1 + 1 = 0+1

t^2 + 5t = 1

Take the square of half of the coefficient of t to have:

t^2 + 5t + (5/2)^2 = 1 + (5/2)^2

(t+5/2)^2 = 1+25/4

(t+5/2)^2 = 29/4

t + 5/2 = ±√29/4

t = -5/2 ±√29/4

Hence the solution to the given quadratic equation using the completing the square method is t = -5/2 ±√29/4

Answer:

LCD = 12

Step-by-step explanation:

The principal is $145 .

Simple interest is the interest amount for a particular principal amount of money at rate of interest. The interest is calculated by multiplying the principal with the time and rate. The total amount after a certain time is given by the sum of the  principal and the interest for that time.

The formula for calculating the Interest on a Principal(P) , time(t) and rate(R).

Interest=P×R×t

Now let us consider the principal to be P.

Time(t)=5 years

Simple Interest(I)=$87

Rate(R)=12%=0.12

Now let us find the principle for the this interest using the above formula.

I=P×R×t

Substituting the given values we calculate the Principal(P).

[tex]87=P\times0.012\times5\\or,P=87\div(0.012\times5)\\or,P=87\div0.6\\or,P=145[/tex]

Therefore the Principal for the simple interest of $87 for 5 years at rate of 12% is $145.

The length of the parallelogram is 16 m and the width of the parallelogram is 12 m.

We are given that the perimeter of a parallelogram is 56 m.

Let the length of the parallelogram be x meter.

So, we get that the width of the parallelogram will be = x - 4 meter.

We also know that:

Perimeter of parallelogram = 2 ( l + b )

Substituting the values in this, we get that:

56 = 2 ( x + x - 4 )

56 = 2 ( 2 x - 4 )

28 = 2 x - 4

2 x - 4 = 28

2 x = 28 + 4

2 x = 32

x = 16

Length = 16 m

Width = 16 - 4 = 12 m

Therefore, the length of the parallelogram is 16 m and the width of the parallelogram is 12 m.

It is given that RSTU is a parallelogram, so RU ∥ ST by the definition of parallelogram.

Therefore, ∠1 ≅ ∠2 by the alternate interior angles theorem, and m∠1 = m∠2 by the angle congruence postulate .

It is also given that ∠1 and ∠3 are complementary, so m∠1 + m∠3 = 90° by the definition of complementary .

By substitution, m∠2 + m∠3 = 90°, and so ∠2 and ∠3 are complementary by the definition of complementary.

From the given image of the parallelogram, we are given that;

Angle 1 and angle 3 are complementary.

Now, complementary angles sum up to 90°. Thus;

∠1 + ∠3 = 90°

Now, according to definition of parallelogram, we know that alternate interior angles of a parallelogram are congruent(equal). Thus;

∠1 = ∠2

Since ∠1 = ∠2, then by substitution property into the first equation, we have; ∠2 + ∠3 = 90°

Since the sum of ∠2 and ∠3 is equal to 90°, then we can say that they are both complementary angles.

Thus, we conclude that;

It is given that RSTU is a parallelogram, so RU ∥ ST by the definition of parallelogram.

Therefore, ∠1 ≅ ∠2 by the alternate interior angles theorem, and m∠1 = m∠2 by the angle congruence postulate .

It is also given that ∠1 and ∠3 are complementary, so m∠1 + m∠3 = 90° by the definition of complementary .
