Some equations have the form y=kx, where k is a number. Which equation CANNOT be written in the form y=kx?

kumpel [21]

Answer:

Any equation of the form

y = kx + b,

with b different from zero

Step-by-step explanation:

For example

y = 5*x +3

cannot be written in the form

y = k*x, because there is a term that shifts the graph upwards.

Which equation is the equation of a circle with a diameter of 20 cm and center at (-3, 6)?

larisa86 [58]

The equation of a circle with centre (a,b) and radius r is:
(x - a)^2 + (y - b)^2 = r^2
thus,
here centre (a,b) = (-3,6), a = -3, b = 6
and radius = diameter/2 = 20/2 =10 units
therefore, the equation is
(x + 3)^2 + (y - 6)^2 = 100
which is c.

Read the proof. Given: m∠H = 30°, m∠J = 50°, m∠P = 50°, m∠N = 100° Prove: △HKJ ~ △LNP Triangles H K J and L N P are shown. Trian

SVETLANKA909090 [29]

Answer:

Triangle Sum Theorem

Step-by-step explanation:

Statement

2. m∠H + m∠J + m∠K = 180°

Reason

Triangle Sum Theorem

Comments

-----------

In any given triangle the sum of its interior angles must be equal to 180º.

This has to do with lines and parallelism, and if you trace a Triangle and to parallel lines one of them being the base of it, this can be proven too.
