Which example illustrates an improper use of deductive reasoning? a. all girls in mrs. lopez’s class have brown hair. cassandra is in mrs. lopez’s class. therefore, cassandra has brown hair. b. all isosceles triangles have two congruent sides. abc is a triangle therefore abc two congruent sides. c. all residents of townsburg have a pet. josiah lives on the north side of townsburg. therefore, josiah has a pet. d. all rhombi have diagonals that intersect at right angles. a square is a type of rhombus. therefore, a square’s diagonals intersect at right angles.

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

step-by-step explanation:

hj=3x+20

ji=15x-64

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.
