Answers
Answer:
x = -3/10
Step-by-step explanation:
Solve for x by substituting y = 3x into the other equation:
2x - 4y = 3
2x - 4(3x) = 3
Simplify and solve for x:
2x - 12x = 3
-10x = 3
x = -3/10
So, x = -3/10
Answer:
[tex]x=-\frac{3}{10}[/tex]
Step-by-step explanation:
2x - 4y = 3
y = 3x
2x - 4(y = 3x) = 3
2x - 4(3x = 3)
2x - 12x = 3
- 10x = 3
- 10x ÷ - 10 = 3 ÷ - 10
[tex]x=-\frac{3}{10}[/tex]

Find the value of sin T rounded to the nearest hundredth, if necessary.
Answers
========================================
Work Shown:
sin(angle) = opposite/hypotenuse
sin(T) = VU/VT
sin(T) = 3/5
sin(T) = 0.6
The value of sin(T) = 0.6.
How to estimate the value of sin(T)?If θ exists in one of the acute angles in a triangle, then the sine of theta exists the ratio of the opposite side to the hypotenuse, the cosine exists the ratio of the adjacent side to the hypotenuse, and the tangent exists the ratio of the opposite side to the adjacent side.
Given: VT = 5, VU = 3 and UT = 4.
sin(angle) = opposite/hypotenuse
sin(T) = VU/VT
sin(T) = 3/5
sin(T) = 0.6
Therefore, the value of sin(T) = 0.6.

C. Horizontal
Answers
Answer:
B. Decreasing
Step-by-step explanation:
From the table, we can see that as variable x increases, variable y decreases relatively.
If the data points are plotted on a scatter plot, the trend line would be sloping downwards from our left to our right. This shows that the trend line is decreasing because the sloping downwards from the left to the right shows implies a decrease.

If the player moves the knight from (5, 1) to (6, 3), the translation made is 1 square up, 1 square right2 squares up, 1 square right4 squares up, 2 squares right2 squares up, 1 square left.
Answers
Answer:
The answer is below
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
Translation is the movement of a point either up, down, right or left in the coordinate plane. If a point A(x, y) is moved a units up and b units right, then the new point is at A'(x + b, y + a).
Given that the knight is moved from (3, 2) to (5, 1), hence it is moved 2 squares right and 1 square down.
If the knight is moved from (5, 1) to (6, 3), it is moved 1 square right and 2 squares up.

A game spinner is divided into 5 congruent sections and labeled, as shown below.
The arrow will be spun 100 times. Which of the following is most likely the number of times the arrow will stop on the section labeled “lose a turn”?
Answers
Answer:
G. 20
Step-by-step explanation:
The spinner has a total of 5 equally sized sections. This means that each possible outcome has an equal probability of 1/5 (0.20 in decimal form) that the spinner lands on it. Therefore, to calculate the number of times that the spinner would most likely land on "lose a turn", we need to multiply the probability that we just mentioned by the number of times the spinner will be spun...
0.20 * 100 = 20 times
Finally, we can see that the spinner will most likely land on "lose a turn" 20 times in 100 spins.

20
