HElp K 12 test! Will give brainiest PLS HELP!!!!
Salsk061 [2.6K]

Answer:

1. d  2. a  3. d  4. a  5. a

Step-by-step explanation:

For 1, d is negative because, if there an even number of negatives, the answer will be positive. a. would have been correct, but you multiply that one by 0. 0 is not negative, so the answer has to be d.

2. is -21. You can multiply 3 times seven then make it negative, or simply add -7 together 3 times.

3. is d because the two negatives cancel each other out. Even numbers of negatives cancel each other out. therefore, 17 times 6 is 102.

4. -120 is the answer because there are 3 negatives. That is an odd number, so we know our answer is negative. -5 times -3 is 15, and 15 times -8 is -120.

5. is a because -1 times 4 is -4, then -4 times -9 is 36. 36 times -3 is then -108.

The simplified form of the difference quotient of equation 9x^2+5x-1 . in the form 9x + 9h + 5.

In question for equation 9x^2+5x-1, simplified to difference quotient in the form of Ax+Bh+C where A, B, C are integers

<h3>What is equation?</h3>

equation is the relationship between variable and represented as  9x^2+5x-1  is example of polynomial equation.

We know that,
for difference quotient
=\frac{f(x+h)-f(x)}{h} \\\frac{9(x+h)^2+5(x+h)-1-9x^2-5x+1}{h}\\\frac{9h^2+9hx+5h}{h}\\9x+9h+5
While, compared with Ax+Bh+C
we have A=9, B=9, C=5.

Thus, The required value of difference Quotient in the form Ax+Bh+c where A, B and C is 9, 9 and 5 respectively
