first find bx by substituting in 10 for x in the equation for the number of dogs. so... bx=2(10) - 5 = 15. we need 15 bags of dog food. now substitute in 15 for x in the m(x) equation 3(15)+1= 46. $46 to purchase 15 bags of dog food for 10 dogs. hope this helps.

**MULTIPLY. WRITE EACH PRODUCT IN SCIENTIFIC NOTATIO**

multiply the constants together (3x2) to get 6 and then since you are multiplying and the bases are the same (the 10's) you can just add their exponents to make 10^18. so you now have 6 * 10^18. done. Same thing for the next one.

**algebra**

use the distributive property.... multiply the -x by 6x and get -6x^2 minus the -x times the 7 to get -7x. then multiply everything by a -1 to get rid of the negative signs.
