Answer:
16w+40
Step-by-step explanation:
To simplify this equation you have to use the distributive property first. This means you multiply 4 by everything in the first set of parentheses and you multiply 6 by everything in the second set of parentheses. This leaves you with 4w+16+24+12w.
Next, you combine like terms by adding 4w and 12w to get 16w, and 16 and 24 to get 40.
So, your final answer is 16w+40.
1) "Subtract -7a+1 from 7+a" means -7a+1 is getting taken away from 7+a, so this can be mathematically expressed as:
Starting expression: (7+a)-(-7a+1)
Distributive property with negatives: 7+a+7a-1
Combine like terms: 6+8a
So the answer for the first one is 6+8a
2) "Subtract -4v-2 from -2-5v" means -4v-2 is getting taken away from -2-5v, so this can be mathematically expressed as:
Starting expression: (-2-5v)-(-4v-2)
Distributive property with negatives: -2-5v+4v+2
Combine like terms: -v
So the answer for the second one is -v
Hope these explanations are clear.
Part C: Treat these two expressions as separate functions. Then f(x) = 4^(-x) and g(x) = 2^x + 3. Graph these functions separately on the same set of coordinate axes. Determine the coordinates of the point of intersection of the two graphs. That's your "solution," or at least the x-component of it. To find the y-component, substitute your "solution" into either f(x) or g(x). Write your final solution in the form (x,y).
Answer:
Step-by-step explanation:
(26!/20!)(5!/2!)=9945936000
Refine:
Multiply both sides by 3 :
Refine:
Subtract 15 from both sides:
Divide both side by -2 :
