Three‌ ‌sets‌ ‌of‌ ‌a‌ ‌sum‌ ‌of‌ ‌a‌ ‌number‌ ‌and‌ ‌four‌ ‌are‌ ‌added‌ ‌to‌ ‌the‌ ‌sum‌ ‌of‌ ‌seven‌ ‌times‌ ‌the‌ ‌same‌ ‌number‌ ‌and‌ ‌thirteen.‌

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
