Answer:
3
Step-by-step explanation:
because she uses beads
so the number of beads go down
You have not added your options, so I will just solve and hope that my answer is in your choices.
For the first equation we have:
3x-1=7+2
3x = 7+2+2
3x = 10
x = 10/2
For the second equation we have:
<span>2x+1+4=3
</span>2x = 3-4-1
2x = -2
x = -1
Therefore, there isn't a solution that satisfies both equations. Based on this, this system of equations has no solution.
I believe the answer is true! Hope this helps!
<span>B. {x|–5 < x < 6} and</span>C. (–5, 6)
3(x - 2) < 18 and h + 6 > -3h + 12 would be graphed with an open circle.
Open circle is a term used for numbers that are less than (<) or greater than (>). On the other hand, Closed circle is used for numbers that are less than or equal to (≤ ) and greater than or equal to (≥).
Here, we are given four inequalities, let us check them one by one-
A. h + 6 > -3h + 12
⇒ 4h > 6
or h > 3/2
Here, we see that there is no equality sign, this means that 3/2 won't be included and hence h + 6 > -3h + 12 would be an open circle inequality.
B. 7 ≥ d/3
⇒ d ≤ 21
Here, we can clearly see the equality sign which means that 21 will be included. Hence, 7 ≥ d/3 would not be graphed with an open circle.
C. 3(x - 2) < 18
x - 2 < 6
x < 8
Here, we see that there is no equality sign, this means that 8 won't be included and hence 3(x - 2) < 18 would be graphed with an open circle.
D. 2y ≤ 14
y ≤ 7
Here, we can clearly see the equality sign which means that 7 will be included. Hence, 2y ≤ 14 would not be graphed with an open circle.
Thus, 3(x - 2) < 18 and h + 6 > -3h + 12 would be graphed with an open circle.
