One way to solve the system is to <u>substitute</u> a variable.
<u>Explanation:</u>
One approach to solve an equation is by substitution of one variable. Right now, a condition for one factor, at that point substitute that arrangement in the other condition, and explain. All value(s) of the variable(s) that fulfills a condition, disparity, arrangement of conditions, or arrangement of imbalances.
The technique for tackling "by substitution" works by settling one of the conditions (you pick which one) for one of the factors (you pick which one), and afterward stopping this go into the other condition, "subbing" for the picked variable and fathoming for the other. At that point you back-explain for the principal variable.
Answer:
x + 3y > 6
Step-by-step explanation:
Find two points that satisfy x + 3y = 6 and draw a DASHED line through them.
It is greater than so shade the section ABOVE that line.
Using the intercept method, the two points I chose are: (0, 2) & (6, 0)
y ≥ 2x + 4
Find two points that satisfy y = 2x + 4 and draw a SOLID line through them.
It is greater than so shade the section ABOVE that line.
The two points I chose are: (0, 4) & (1, 6)
The solution is where the shaded sections overlap.
Answer:
1/50 < 2.8% < 0.044 < 7/40
Step-by-step explanation:
2.8%, 7/40, 1/50, 0.044
- 2.8% = 0.028 = 28/1000
- 7/40 = 0.175 = 175/1000
- 1/50 = 0.020 = 20/1000
- 0.044 = 44/1000
<u>Ordering in ascending order</u>
- 20/1000 < 28/1000 < 44/1000 < 175/1000
<u>Same order in original numbers</u>
- 1/50 < 2.8% < 0.044 < 7/40
710/70 = 10.14, so round up to 11. The answer is C.
