Answer:
you multiply 10*2=20
and 2+3=5
Step-by-step explanation:
is this right or wrong?
Point slope form is:
y -

= m(x -

)
With

and

being the coordinate points, and m being the slope.
So the coordinate points are (4, -5), and the slope is -6 in this case.
So just substitute everything in, to get:
y - ( -5) = -6(x - 4)
Or
y + 5 = -6 (x - 4)
Answer: C
Step-by-step explanation:
Perpendicular lines are irrelevant. A is to create a triangle and to show 2 angles in the triangles are congruent. B is to prove the 2 triangles are congruen. D is to prove that AC and BD are congruen. no where is perpendicular lines involved.
Answer:
The second option or B
Step-by-step explanation:
The approximate total mass= number of atoms * weight of an atom.
The approximate total mass=3.06 10²³ atoms. (1.67 10⁻²⁴ grams/1 atom)=
=0.51102 g ≈ 0.51 g
Answer: the approximate total mass is 0.51 grams.
