substitute the values from the quadratic formula.
a= 3
b= -5
c= -3
simplify the numerator
5±√61/2 times 3
Multiply 2 by 3
<h2><em>
ANSWER:5±√61/6</em></h2>
Answer:
It is linear because there's a constant change in both x and y
Step-by-step explanation:
There is a constant change in x: +3
There is a constant change in y: -2
Therefore, the slope is -3/2, making the function linear.
Triangle a - acute
Triangle b - acute
Triangle c - acute
Triangle d - right
2. So for this question, you do the distributive property, which is multiplying the term outside of the parenthesis by the terms in the parenthesis. In this case, the outside term is 1/2. 8x * 1/2 = 4x and 1/2 * -16 is -8. That brings us to 4x - 8, which is our answer. Therefore, the correct answer choice is B.
3. Okay. In this problem, we are talking about the sum of 12 and a number. That's 12 + n, because sum means the answer to the addition problem D is out, because we don't do distributive property in this case. The sum of 12 + n is 4n. The expression is 12 + n = 4n. The answer is B.
Hey there! :)
You have to use the Pythagorean Theorem ⇒ a² + b² = c²
a = 5
5² = 5 × 5 = 25
b = 13
13² = 13 × 13 = 169
169 + 25 = 194
√194 = 13.93
That means McKenzie is correct and Cara is wrong ; c = 13.93
Hope this helps :)
