3rd option: $-\frac{1}{2} < t \leq 3$ is the correct answer

Step-by-step explanation:

First of all, we have to observe the number line

Observing the number line we can see that the number -0.5 or -1/2 is not included in the solution as the circle on -1/2 is empty. An empty circle means that the number is not included in the solution.

While on the other side we can see that 3 has a filled circle which means 3 is included in the solution

This means that the solution might be:

$t>-0.5\\and\\t \leq 3$

By comparing the observation and the answer choices we can conclude that

3rd option: $-\frac{1}{2} < t \leq 3$ is the correct answer

Mr. Smith borrowed $22,000 to purchase stock for his baseball card shop. He repaid the simple interest loan after four years. He

Stella [2.4K]

Based on the calculations, the interest rate on the stock in four (4) years is equal to 7.1%.

<u>Given the following data:</u>

Amount borrowed (Principal) = $22,000.

Simple interest, I = $78.40.

Time = 4 year.

To determine the interest rate on the stock in four (4) years:

<h3>How to calculate simple interest?</h3>

Mathematically, simple interest can be calculated by using this formula:

I = PRT

<u>Where:</u>

S.I is the simple interest.

P is the principal or starting amount.

R is the interest rate.

T is the time measured in years.

Making R the subject of formula, we have:

R = I/PT

Substituting the given parameters into the formula, we have;

R = 6260/(22,000 × 4)

R = 6260/(88,000)

Interest rate = 0.071 = 7.1%.

Answer:

The solution is: (1,-3)

Step-by-step explanation:

Given equations are:

x-y=4 Eqn 1

4x+y = 1 Eqn 2

Substitution involves finding value of a variable from one equation and putting in other equation

From equation 1

x = y + 4

Putting in equation 2

$4(y+4) + y = 1\\4y+16+y = 1\\5y = 1-16\\5y = -15\\\frac{5y}{5} = \frac{-15}{5}\\y = -3$

Putting y = -3 in equation 1

$x- (-3) = 4\\x + 3 = 4\\x = 4-3\\x = 1$

Hence,

The solution is: (1,-3)
