Answer:

1. -3    

2. 7      

3. -2        

4. 3

Step-by-step explanation:

1.      idk

2.     3.2 move 3b over to get 3.2-3b-4.7=-3.3 move 4.7 over to get

3.2b-3b=4.7-3.3 now 3.2b-3b=.2b and 4.7-3.3=1.4  .2b/.2=b   1.4/.2=7 so b=7

3.     4.6y-y+4=y-1.2 now switch the 4 and the y to read 4.6y-2y=-4-1.2

2.6y=-5.2 divide both sides by 2.6 to get y=-2

4.      7.5c-2.5c+8=-7 move 8 to other side to get 7.5c-2.5c=-8-7

5c=-15 divide both sides by 5 getting c=3

user100 [1]

Answer:

57 inches

Step-by-step explanation:

The height, width, and diagonal of the TV screen form a right triangle.

Use the pythagorean theorem, a² + b² = c², and solve for c, the hypotenuse/diagonal of the TV.

a² + b² = c²

30² + 48² = c²

900 + 2304 = c²

3204 = c²

56.6 = c

Round this to the nearest inch:

56.6

= 57

So, the diagonal of the TV screen is 57 inches

Given the following functions f(x) and g(x), solve (f ⋅ g)(3) and select the correct answer below:
Ksenya-84 [330]
I believe you may have the order incorrect. If we were looking at g(f(x)) the answer would be 47. We would get this by sticking the 3 in for x in f(x) and solving, which would give us 48. We would then stick that answer in for x in the g(x), giving us 47. 

In its current order the answer would be 28.
