Step 1. You must write down/ underline all the numbers given in the problem.
Step2. Identify all the unknown variable such as x, y, a, b [those are the most common ones].
Step 3 Identify what sign of operation your working with... It can be +,-,×,÷.
Step 3 write down all your terms on the LHS of the equation.
Step 4. Equate all the constant on the RHS of the equation. If the constant was negative It would be positive and vic versa
Step. Solve your problem
Answer:
-1.67539
Step-by-step explanation:
A ray has one point and goes in one direction forever.
Answer:
14 ° and 76 °
Step-by-step explanation:
We have that two angles are complementary, if the sum of their amplitudes is 90 °.
The complementary angles need not be consecutive or have any point in common.
Alpha and Beta are complementary if:
Alpha + Beta = 90 °
In this case it would be:
X - 76 ° = 90 °
X = 90 ° - 76 °
X = 14 °
Which means that each angle measures 14 ° and 76 °
Answer: 24
<u>Step-by-step explanation:</u>
Let's find one solution:
3x² + 7x + c = 0
a=3 b=7 c=c
First, let's find c so that it has REAL ROOTS.
⇒ Discriminant (b² - 4ac) ≥ 0
7² - 4(3)c ≥ 0
49 - 12c ≥ 0
-12c ≥ -49
Since c must be a positive integer, 1 ≤ c ≤ 4
Example: c = 4
3x² + 7x + 4 = 0
(3x + 4)(x + 1) = 0
x = -4/3, x = -1 Real Roots!
<em>You need to use Quadratic Formula to solve for c = {1, 2, 3}</em>
<em />
Valid solutions for c are: {1, 2, 3, 4)
Their product is: 1 x 2 x 3 x 4 = 24
