select three ratios that are equivalent to
4: 3

choose 3 answers:

1) 8:6      2) 12:9        3) 16:12

Step-by-step explanation:

1) You multiply both 4 and 3 by 2.

2) You multiply both 4 and 3 by 3

3) You multiply both 4 and 3 by 4.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
