Usually, we use the number line to solve inequalities with the symbols,
<
,
≤
,
>
, and
≥
.(the second and last one was rather hard to find on my keyboard) In order to solve an inequality using the number line, though, just turn
the inequality sign to an equal sign. Then, solve the equation. Next step,
graph the point on the number line (remember to graph as an open circle if the
original inequality was <, or >). The number line should now be
divided into 2 regions, one to the left of the graphed point, and one to the
right of said point.
After that, pick a point in both regions and "test" it, check to see if it satisfies
the inequality when plugged in for the variable. If it does, draw a darker line from the point into that region, with an
arrow at the end. That is the solution to the equation: if one
point in the region satisfies the inequality, the entire region will
satisfy the inequality.
I had to check back in an old textbook to remember all of that. Sorry about the earlier answer. That was rather foolish to do so without actually understanding the question.
B, y goes up 8, when you add 8 to y
Answer: Pt = Ng / Nt
Step-by-step explanation:
Where Ng = number of customers that order food to go as reported at Anita's
Nt = total number of customers reported at Anita's
Pt = probability that a customer will order food to go at Anita's
Pt= Ng/Nt
Goodluck...
Answer:
B) Y-intercept: (0,3), X-intercept: (4,0)
Step-by-step explanation:
x = 0 12y = 36-9x
12y = 36
y = 3 y intercept: (0,3)
y = 0 9x = 36 x = 4
x intercept: (4,0)
Answer:
x=38
Step-by-step explanation:
First, know that the sum of the angles in a triangle is 180.
Then, add the angles. 2x+38+x+x-10.
Make them equal to 180.
2x+38+x+x-10=180
Simplify.
4x+28=180
Subtract 28 from 180.
4x=152
Divide 4 from 152 to make x alone.
x=38
There you go!
