Hello there! The answers are -2x and -5x.
Like terms are terms that have the same x values and exponential values. Out of the options you have provided, the only terms that have like terms are -2x and -5x since they both have a value of x to the first power. 2 and 6x^2 both have different exponential values of x, so they are not like terms.
I hope this helps and have a great rest of your day!
divide cost by quantity. The lowest rate is the best buy:
26/8 = 3.25 each
30/5 = 6.00 each
15/4 = 3.75 each
39/12 = 3.25 each
45/10 = 4.50 each
The 8 for 26 and the 12 for 39 are both the same price each and are the better buys.
Well, first of all, you have to open up the bracket by multiplying what's outside by what's inside. Anyway;
3k-15=-16
Next, you have to collect the like terms and put them together. And the -15 becomes +15. So;
3k=-16+15
3k=-1
Next, you have to divide the both sides by 3. So;
3k/3=-1/3
k=-1/3
So your answer is -1/3. Hope i helped. Have a nice day.
Answer for 1 & 3 : -x(1-5y) / (5x-2y)(25x^2+10xy+4y^2)
Answer:
y=10.75
Step-by-step explanation:
46 + 1) + y = 5(y - 1) +9
47+y=5y-5+9
47+y=5y+4
Collect like terms
47-4=5y-y
43=4y
Divide by 4
43/4=4y/4
43/4=y
y=10.75
