Answer: y = 40deg, x = 80deg
Step-by-step explanation:
1. Because we see that there are parallel lines in the triangle to the left, we know that two of the angles of that triangle are 50deg
2. using the fact that triangles have a total of 180deg we get x = 80deg
To solve for y, we also know that there are two angles in that triangle which are the same, and one of them is y, therefore 2y + 100deg = 180deg, meaning 7 = 40deg

You deposit $200 in an account that earns 4% simple interest. How much interest did you earn in 3 years? (Hint: I = prt)
Answers
Answer:
$24.
Step-by-step explanation:
Given that I deposited $ 200 in an account that earns 4% simple interest annually, to determine how much interest did I earn in 3 years, the following calculation must be performed:
((200 x 4/100) x 3) = X
((800/100) x 3) = X
(8 x 3) = X
24 = X
Thus, after 3 years of investment I will have earned $ 24 in interest.
how can you
change the equation y = mx + b to
shift the graph down?
Answers
Step-by-step explanation: To shift the graphs up and down on the coordinate system, you need to manipulate or change the y-intercepts.
The y-intercept is just the constant term in the equation.
As long as the slopes remain the same, the graphs can be
translated up or down by changing the constant value.
Take a look at these lines graphed below.
Notice that y = x + 11 is the same as y = x + 4 but
y = x + 11 is translated 7 units down to get y = x + 4.
Juan ramirez sells suits in a major department store on weekends he Ernst a commission of 5 percent on the first ten suits and he sells more than ten he Ernakulam additional 3 percent last weekend he sold thirteen 250 suits what was his commission?
Answers
Answer:
$185
Step-by-step explanation:
The first ten suits sold for 10×$250 = $2,500
commission = 5% of $2,500 = 0.05×$2,500 = $125
The next three suits sold for 3×$250 = $750
commission = 8% of $750 = 0.08×$750 = $60
Total commissions = $125+$60 = $185

Your height is found in the line in the middle of the triangle, for you it is 6.
The base is the long bottom line on the triangle (lineJL), for you it is 8.
So let's put it in.
A=1/2(8)(6)

Huy is solving a quadratic equation by completing the square. His first few steps (steps 1-4) are shown below. Which of the following statements is true regarding Huy's work?
Given x2+3x−5=0
Solution x2+3x=5 step 1
x2+3x+9=5+9 step 2
(x+3)2=14 step 3
x=−3±14−−√ step 4(1 point)
Huy is incorrect. He made a mistake in step 1 when he added a 5 to both sides. He should have only added a 5 to the left side of the equation.
Huy is incorrect. He made a mistake in step 4 when he solved the equation (x+3)2=14 for x.
Huy is incorrect. He made a mistake in step 2 of the solution when he added a 9 to both sides.
Huy is correct. He has done a nice job of completing the square.

The true statement will be;
''Huy is incorrect. He made a mistake in step 2 of the solution when he added a 9 to both sides.''
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The quadratic equation is,
⇒ x² + 3x - 5 = 0
Now,
Huy is solving a quadratic equation by completing the square.
The steps are;
The quadratic equation is,
⇒ x² + 3x - 5 = 0
Solution; x²+3x=5 (step 1)
x²+3x+9 = 5+9 (step 2)
(x + 3)² = 14 (step 3)
x = - 3 ± √14 (step 4)
Clearly, In step 2 when add 9 then it not make the square form.
That is,
x² + 3x + 9 ≠ (x + 3)²
Thus, The true statement will be;
''Huy is incorrect. He made a mistake in step 2 of the solution when he added a 9 to both sides.''

Which integer represents this scenario?
an elevator goes down 2 floors
Answers
Answer:
We usually define the cases like this as follows:
If we go upwards N units, then we add N.
If we go downwards N units, then we subtract N.
In this case, suppose that the elevator is originally on the floor K (can be any integer number larger or equal than 2)
Then the elevator goes down 2 floors.
Then now the elevator will be on the floor (K - 2)
Then the integer that represents this scenario is -2, which represents the change in the floor number where the elevator is.
