For the elimination method, you need to have one variable that eliminates and cancel each other out. In this question lets use the variable y. A common denominator for y in the equation would be -8 since we want the variables y to cancel out. We already have 8y for the second equation. Now to get -8y for the first equation we need to multiply everything by -2 this would leave us with 14x+-8y=2. Now all you have to do is add the two equations. 10x=-10. So the final answer for x is -1. To find y just substitute the x value in the first equation which would give you y=-2. See that wasn't so hard:))

Answer:
A consumer pays $5 more per camera.
Step-by-step explanation:
Let the cost of manufacture of disposable camera in dollars be
Government taxes imposed on camera = $1.00 per camera
Cost of camera after taxes in dollars
Wholesale prices raised by manufacturer = $2.00 per camera
Wholesale price of camera in dollars per camera
Retail prices raised raised by retailer = $2.00 per camera
Retail price of camera in dollars per camera
Difference in prices of manufacture and retail price per camera in dollars
⇒
⇒
Thus, a consumer pays $5 more per camera.
Answer:
Step-by-step explanation:
Apparently, you're supposed to recognize that the formula tells you the value of cos(x/2).
Answer:
1.) -3
2.) 20
3.) is either - 25 or just 25 (depends if you have parentheses around the -5)
Step-by-step explanation:
2.) 5*2 is 10
2*-5 is -10
10-(-10) =20
3.) parentheses: (-5)^2 = 25
w/o parentheses: -5^2 = -25
