No angles are shown in either triangle, however, 3 sides are congruent. When you have 3 congruent sides (S) you will get
SSS
1. Shift the function down one.
2. Left by 4 units
First to solve the inequality
300 + 5x > 550
5x > 550 - 300
5x > 250
x > 50
Therefor the answers are all numbers bigger than 50
So to solve for an inequality, you must isolate the variable, in this case x, to one side.
Starting with 3.5x - 10 > -3, firstly add both sides by 10:
3.5x > 7
Next, divide both sides by 3.5 and your first half is:
x > 2
Next with 8x - 9 < 39, firstly add both sides by 9:
8x < 48
Next, divide both sides by 8 and your second half is:
x < 6
<u>Putting it together, your final answer is x > 2 and x < 6 or 2 < x < 6.</u>
Answer:
0.25x -12= 18- 0.55x (subtract 0.25x from both sides)
-12= 18 -0.80x (subtract 18 from both sides)
-30= -0.80x (divide each side by -0.80)
x= 37.5 (this is your answer)
