Answer:
s = 22°
Step-by-step explanation:
158° and u are supplementary angles ( straight angle )
u = 180° - 158° = 22°
s = u = 22° ( complementary angles )
Answer: the solution to the inequality is -3 < x < 4. Graphically, this should be (2)
Step-by-step explanation:Note that x^2 - x - 12 factors to (x - 4)(x + 3) < 0, so we have:
(x - 4)(x + 3) < 0.The only way for (x - 4)(x + 3) to be negative is if x - 4 and x + 3 have opposite signs. This only occurs when:
(i) x - 4 < 0 AND x + 3 > 0
==> x < 4 AND x > -3; both occur when -3 < x < 4.
(ii) x - 4 > 0 and x + 3 < 0, which cannot happen at the same time.
Answer: x=3
Step-by-step explanation: Hello! I hope you are having a great day :)
For this question, you will have to distribute in order to do that, you will need to multiply what's inside the parenthesis by 5. From there you get the equation 3 - 10x + 25= -2. So from this equation, we can then add the coefficients which becomes 28 - 10x = -2. We will then have to move the constant variable (28) over to the right-hand side and change the sign. Our new equation becomes -10x = -2 - 28. We then will calculate our new equation which becomes -10x = -30. Next we divide both sides by -10 in order to make -10x into just x. -30 divided by -10 equals 3. Therefore, our answer is x=3.
