Answer: x > -7
Step-by-step explanation:
so first, we move the constant to the right.
-3x < 15 + 6
the, we calculate that.
-3x < 21
then, we divide both sides.
solution: x > -7
The answer is 7.3 or in other words 7 3/10

Answer:
d
Step-by-step explanation:
the reciprocal of any number n is 1/n
only d has the same reciprocal as 1 = 1/1
8. 4x²+3y = 4(4)²+3(5) = 4(16)+15 = 64+15 = 79
basically you have to substitute the variable for the given value. (ex. x is replaced by 4 and y is replaced by 5 and z is replaced by 3) FOR BOTH PROBLEMS!
9. (y+z)/x = (5+3)/4 = 8/4 = 2
To solve for x in an inequality is very similar to solving for x in an equation since for both you would need to isolate x.
step 1) -2x-4>8 add the 4 over to move any constants over to the +4 +4 other side.
-2x> 12
step 2) x< -6 Divide out the -2 to isolate x, however, keep in mind, when you divide or multiply over any negative number, you must also remember to flip the inquality sign.
Answer: x<-6
