See explanation

Step-by-step explanation:

A. There are 8 points: A, B, C, D, E, F, G and H

B. There are 9 lines in the figure: AB, BC, AC, DE, DF, EF, BE, AD and CF

C. There are 5 planes in the figure: ABC, DEF, ABED, ACFD and BEFC

D. Three points are collinear if they lie on the same line. Collinear points are D,G and F or C,H and F

E. Coplanar points are those which lie in the same plane. Coplanar points are B, E, F and C or A, C, F and D or A, B, E and D or other combinations of four points lying in the same plane

I. Planes ABC and ABE intersect by a line AB

G. Planes BCH and DEF intersect by a line EF

H. Lines AD and DF intersect at a point D

Can someone help me with (a) and (c)? Thanks! ;D

Answer:

Step-by-step explanation:

a) Mark any two points in line a

(0,7) ; (5,-3)

Find the slope

slope = y2 - y1 /x2-x1

$=\frac{-3-7}{5-0}\\\\=\frac{-10}{5}\\\\=-2$

Equation: y-y1 = m(x-x1)

y - 7 = -2(x - 0)

y - 7 = -2x

y = -2x + 7 --------> line a

c) equation of line b

(2,-1); slope = -2 {as b line is parallel to line a}

y - y1 =m(x-x1)

y -(-1) = -2*(x - 2)

y + 1 = -2x - 2*-2

y + 1 = -2x + 2

y = -2x + 2 -1

y = -2x +1 ------> equation of line b

Select the correct solution for the expression. 2/5 + 3/8

Answer:

because when you try to find the common denominator the lowest number is 40. so you then multiply the 2x8 and the 3x5 that gives you 16/40 + 15/40 = 31/40
