3.5x-10>-3 add 10 to both sides
3.5x>13 divide both sides by 3.5
x>26/7
x=(26/7, +oo)
...
8x-9<39 add 9 to both sides
8x<48 divide both sides by 8
x<6
x=(-oo,6)
Since this is a compound inequality with AND the solution set will be the union of the two intervals found above.
x=(26/7, 6)
Answer:
b=5
Explanation:
b= the Y-intercept
The formula y=mx+b uses a y intercept (b)
b=5
Answer:
.875
Step-by-step explanation:
7 divided by 8 is .875.
6 - a =

(9a - 18)
First, simplify

to

/ Your problem should look like:
Second, multiply both sides by 3. / Your problem should look like:
Third, expand. / Your problem should look like:
Fourth, add 3a to both sides. / Your problem should look like:
Fifth, simplify 9a - 18 + 3a to 12a - 18. / Your problem should look like:
Sixth, add 18 to both sides. / Your problem should look like:
Seventh, add 18 + 18 to get 36. / Your problem should look like:
Eighth, divide both sides by 12. / Your problem should look like:
Ninth, since 3 goes into 12 to get 36, simplify

to 3. / Your problem should look like:
Tenth, switch sides. / Your problem should look like:

Answer:
a = 3 (one solution)
