I’m pretty sure it would be a and b
You have to ask the question with the right type of something.
Answer:
1/4x (8 x - 15)
Step-by-step explanation:
write the division as a fraction
1/2x + 3/2x (x - 5 ÷ 2)
factor out 1/2 from the expression.
1/2x(x + 3(x - 5 ÷ 2))
divide the numbers.
1/2x(x + 3(x - 2.5))
distribute 3 through the parentheses.
1/2x(x + 3x - 7.5)
collect like terms.
1/2x(4x - 7.5)
1/2x(4x - 15/2)
factor out 1/2 from the expression.
1/2 x 1/2 x (8 x - 15)
multiply the fractions
= 1/4 x (8x - 15)
or alternative form
= 0.25(8x - 15)
Answer: Its the first one
You draw the graph of the line y=3x+5
but make the line dotted.
Label the line y>3x+5
Note that if instead we hade y≥3x+5 the line would be solid.
If you draw a line parallel to the y-axis through any x-value the value of y can be any on that vertical line that is above but not on the line y=3x+5
. So you end up with a 'feasible' region of solutions for y
Answer:
5x+y=12
Step-by-step explanation:
10x+2y=-2=5x+y=12
