Answer:
The ordered pairs are (5,-12), (-1,-1).
Step-by-step explanation:
Given : Inequality 
To find : Which ordered pairs are solutions to the inequality ?
Solution :
We put the given options the point which satisfied the equation is the solution.
Inequality 
1) (5,-12)



It is true.
2) (-1,-1)



It is true.
3) (-3,0)



It is false.
4) (4,-12)



It is false.
Therefore, The ordered pairs are (5,-12), (-1,-1).
Y= 7x - 7z -9
+9 +9 Y+9+7z /7=x
Y+9 = 7x - 7z
+7z +7z
Y+9+7z = 7x
/7 /7
Answer:
x=3
Step-by-step explanation:
for 17.
we have that x=8 as one solution
then we have
x-8=0
so we know that


so we divide and get that

and we can factor it as

so the other solutions are
x-3 =0
x = 3
this is a normal division
Answer:
4.62%
Step-by-Step Explanation:
Ask yourself: "3 is what percent of 65?" and solve.
Percentage solution with steps:
Step 1: We make the assumption that 65 is 100% since it is our output value.
Step 2: We next represent the value we seek with <em>x</em>.
Step 3: From step 1, it follows that 100%=65.
Step 4: In the same vein, x%=3.
Step 5: This gives us a pair of simple equations:
100%=65(1)
x%=3(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100% / x% =65 / 3
Step 7: Taking the inverse (or reciprocal) of both sides yields
x% / 100% =3 / 65
---> x = 4.62%
Therefore, 3 is 4.62% of 65.
