Answer:
4^3 x 5^2
Step-by-step explanation:
Index notation just makes the numbers being multiplied by themselves easier to read.
(First equation:Multiply 6•7=42. 42+5=47)=(second equation:7 to the 2nd power is 49. 49-2=47 )
(7x+2) + (-3x+1) —> 4x + 3 i think
C. Is the closest answer as the total is 18.97
Answer:
5.2
Step-by-step explanation:
g(x) = mx +b
g'(x) = m = 2 for all x
g(-1) = 2(-1) + b = 5
-2 + b = 5
b = 7
So, g(x) = 2x + 7
Therefore g(-.9) = 2(-.9) + 7
= -1.8 + 7 = 5.2
