Going off the given statement we have an angle and a side in each triangle that are congruent to each other. Since vertical angles are congruent, we have now 2 angles and a side, or more specifically, an angle then a side then an angle, which makes those triangles congruent by ASA. That's #3. If the triangles are already proven to be congruent, then anything else that's congrunet between the triangles is because CPCTC. That's #4.

3. PRQ=SRT ASA theorem- angle side angle.

4. PR=SR by the CPCTC Theorem- concurrent parts of congruent triangles are congruent.

What are the domain and range of the function?
Naily [24]

Answer: Domain: (-inf,inf) Range; [-4,inf)

Step-by-step explanation: Domain is x values possible and range is y values possible. Quadratics always have a domain of (-inf,inf) and the range starts from -4 going up infinitely. and if -4 is included then we use a bracket therefore,  [-4,inf). Also, infinity always has a parenthesis.

Let f(x) = x^2 + 4x - 31. for what value of a is there exactly one real value of x such that f(x) = a?
allsm [11]
This value of "a" is exactly the y-coordinate of the vertex of the parabola
y = x%5E2+%2B+4x++-+31.

To find it, complete the square:

x%5E2+%2B+4x++-+31 = %28x%2B2%29%5E2+-+4+-+31 = %28x%2B2%29%5E2+-+35.

So, this value of "a" is a = -35.










Figure. Plot y = x%5E2+%2B+4x++-+31.

If y varies directly with x, Write an equation relating x and y when y = -30 and x = 6.
ziro4ka [17]

Answer:

y=-5x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

so

For x=6,y=-30

substitute

y/x=k------> k=-30/6=-5

therefore

y=-5x
