What is “T” if R(-9,4) and the midpoint S(2,-1) ? HELP!

Answers

So your question is: S is the midpoint of R and T, find T, right?
Suppose T(x,y)
Because S(2,-1) is the midpoint of R(-9,4) and T(x,y) and follow midpoint method we have:

2 = (-9 + x)/2 <=> 4 = -9 +x <=> 13 = x

-1 = (4+y)/2 <=> -2 = 4 + y <=> -6 = y
=> T(13,-6)

Answer:

Step-by-step explanation:

For your safety: “Don’t try to answer a question that you are unsure or don’t know how to solve” (we are always active in brainly and we are more than glad to help you)

Step 1. Get two points off the graph

Points: (0, 3) and (-1, 1)

Step 2. Find the slope

m = slope

m = change in y/change in x

m = (y2 - y1)/(x2 - x1)

m = (1 - 3)/(-1 - 0)

m = -2/-1

m = 2/1

m = 2

The slope is 2

Wendy and Jason, the boy she was babysitting, were playing basketball together. Her score
was 30 points, and his score was 20 points. Wendy wanted to make the game more fair, so
she called a time-out and modified the rules a bit. Wendy explained that, for the rest of the
game, she would get 2 points per basket, and Jason would get 3 points per basket. Then they
played a bit longer. After the time-out, they both made the same number of baskets and
ended up with a tied score. How many points did each person have at the end?
Write a system of equations, graph them, and type the solution.

Answers

Answer:

They both scored 50 points

A third alternative to the formulas I suggested in a comment is to use the vector cross product. Recast the three given points as points in 3D space with 0 z-coordinate:

A(20, 21, 0), B(8, 29, 0), and C(13, 1, 0)

Now consider two vectors,

u = B - A = 〈8, 29, 0〉 - 〈20, 21, 0〉 = 〈-12, 8, 0〉

v = C - A = 〈13, 1, 0〉 - 〈20, 21, 0〉 = 〈-7, -20, 0〉

Then recall the cross product identity,

||u × v|| = ||u|| ||v|| |sin(θ)|

where θ is the angle between the two vectors. The magnitude of u × v is equal to the area of the parallelogram spanned by u and v, and hence twice the area of the triangle of interest.

So we have

area = ||1/2 〈-12, 8, 0〉 × 〈-7, -20, 0〉||

area = 1/2 ||〈-12, 8, 0〉 × 〈-7, -20, 0〉||

area = 1/2 ||〈0, 0, 296〉||

area = 296/2

area = 148

The required subtraction of -8/11 from -17/11 has the outcome of -9/11.

Given that, determine the subtraction of  -8/11 from  -17/11.

What is arithmetic?

According to the statements, mathematics deals with a variety of operations. The four main operations in mathematics are addition, subtraction, multiplication, and division.

What is simplification?

In mathematics, the operation and interpretation of a function to make it simple or easier to grasp is known as simplifying, and the process is known as simplification.

Here,
according to the question,
= -17/11 - (-8/11)
= -17/11 + 8 / 11
= [-17 + 8] / 11
= -9 / 11

Thus, the required subtraction of -8/11 from -17/11 has the outcome of -9/11.

the third one is incorrect because the pattern doesn't match "-15" isn't counting by twos 15 isn't an even number

Answer: The 2nd number line is correct

Explanation:

The first number line is incorrect because the -1, -2, -3 should be reversed to get -3, -2, -1. It's reversed because the negatives are a mirror image of the positive counterpart.

The second number line is correct. Each number shown is separated with a gap size of 20. This gap size stays the same throughout the number line.

The third number line is incorrect. The gap from -15 to -12 is 3 units, while the gap from -12 to -10 is 2 units. We see that the gap size isn't the same through the entire number line.

So to summarize: the gap size must be the same and the numbers must be written in the correct order.

Answer: x = 30°

Concept:

Here, we need to know the idea of an isosceles triangle and the vertical angle theorem.

An isosceles triangle is a triangle that has any two of its sides equal to each other. Also, the angles opposite these equal sides are equal, which is basically the base angles.

The vertical angle theorem states that two vertical angles formed when two lines intersect each other are always equal to each other.

Solve:

Find the other base angle of the isosceles triangle.

Since there are two equal sides, we know that this is an isosceles triangle.

Since the definition said that the base angles are equal, the other base angle would also be x.

Find the value of x

According to the vertical angle theorem, two vertical angles formed by intersection are equal.

Just as angle x and 30°, are vertical angles formed by intersection, therefore, [tex]\boxed{x=30}[/tex]
