Pranza plotted point A in the coordinate plane below

she says that the plotted point is (1/4, -1/2)

A. the x-and y-coordinates are
switched

B. both coordinate should be positive

C. the x-coordinates should be 3 / 4

D. the y-coordinate should be 1/2

The answer to your question is C. The x-coordinate should be 3/4

Step-by-step explanation:

In this graph, the scale is 4 four points equal to 1 unit. So 1 point is 1/4.

The point given is 3 points to the right after the zero. So the x-coordinate is 3/4, not 1/4.

The y-coordinate is correct.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
