I. 2x + x + 8 = 3x - 2
ii. 4(x - 1) + x = 5x -4- x
iii. 7x + 12 = (x + 3) + (x + 4)
iv. x + 2(4-x) = 2x + 6-3x
Which equation(s) has (have) no solution(s)?

i think the answer is b.

step-by-step explanation:

not 100% sure though.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
