If f(x)=-5^x-4 and g(x)=-3x-2 find (f-g)(x)

sukhopar [10]

Answer:

$(f-g)(x) = 5^x +3x -2$

Step-by-step explanation:

The value (f-g)(x) means subtract the function g from f. This can be done by combining only like terms between each.

$(f-g)(x) = 5^x - 4 -(-3x-2)\\(f-g)(x) = 5^x - 4 +3x + 2\\(f-g)(x) = 5^x +3x -2$

Irina-Kira [14]

Not exactly sure which equation you meant:

3(100-b)=6b
300-3b=6b
300=9b
b= about 33

100-3b=6b
100=9b
b=about 11

The line plot shows the weights of packages of meat available at a grocery store. The 3 lightest packages cost $4.40 per pound.

Mnenie [13.5K]

Answer:

$42.40

Step-by-step explanation:

The horizontal axis is in fractions.

The three lightest are two $\frac{5}{8}$ pounds & one $\frac{6}{8}$ pounds. Each cost $4.40 per pound.

So cost = 4.40(5/8+5/8+6/8) = $8.8

Remaining costs 4.80 per pound. We add up the remaining and multiply by 4.80 to get their cost.

cost = $4.80(1+1\frac{1}{8}+1\frac{1}{8}+1\frac{1}{8}+1\frac{2}{8}+1\frac{3}{8})=33.6$

Hence, total cost = 8.8 + 33.6 = $42.40

When x increases from a to a +2, y increases by a factor of 1/4

Troyanec [42]

Answer:

y=7* (0.5)^x

Step-by-step explanation:

We are given that when x increases from 'a' to 'a+2' then y must increase by a factor of 1/4=0.25.

i.e. when x=a and x'=a+2.

then y/y=0.25 where y' is the function after putting x' to the old function.
