Answer:
x = -4, y = 3/2
Step-by-step explanation:
simplify the 1st equation by dividing each term by 4 to get:
x + 2y = -1
-5x + 2y = 23
Subtract to get: 6x = -24
x = -4
find 'y': 2y - 5(-4) = 23
2y + 20 = 23
2y = 3
y = 3/2
Answer:
Use the simple interest formula: A = P(1 + rt) where P is the Principal amount of money to be invested at an Interest Rate R% per period for t Number of Time Periods.
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year.
Solving our equation:
A = 30000(1 + (0.055 × 7)) = 41550
A = $41,550.00
The total amount accrued, principal plus interest, from simple interest on a principal of $30,000.00 at a rate of 5.5% per year for 7 years is $41,550.00.

The area of the trapezoid in the given image is: 49 cm².
<h3>What is a Trapezoid?</h3>
A trapezoid can be described as a quadrilateral that has four sides, whereby one pair of opposite sides are parallel to each other.
<h3>How to Find the Area of a Trapezoid?</h3>
The area of a trapezoid is calculated using the formula, Area = 1/2 × (a + b) × h, where:
a and b represents lengths of the parallel sides of the trapezoid
h = height of the trapezoid.
Given the parameters for the trapezoid as:
a = 6 cm
b = 8 cm
h = 7 cm
Plug in the values into Area = 1/2 × (a + b) × h:
Area of trapezoid = 1/2 × (6 + 8) × 7
Area of trapezoid = 1/2 × (14) × 7
Area of trapezoid = 7 × 7
Area of trapezoid = 49 cm²
Thus, the area of the trapezoid in the given image is: 49 cm².

"help..." said the high schooler.
"No," said Life, "figure it out yourself."
Then the rejected high schooler went to watch YouTube to relieve stress, hour and hours passed by until the high schooler realized he was wasting time.
"Oh no!" He said, "I have wasted time again! How will I ever get pass high school?"
"We will help you," said the flash cards, colored pens, and highlighters "we will be your best friend."
After that day, the high schooler never had an all nighter for the rest of high school. (College is a different story)
Moral of the story: Life and cute cat videos will not help you and your homework. Paying attention in class, making flash cards, making your notes colorful with pens and highlighter are what really helps :)
Oh and asking your teacher for help is great too.
