If f(x)=5x+1 and g(x)=2f(x)+5 then g(-1)=
ollegr [7]
We know f(x)=5x+1. Plug in f(x) in the g(x) function.
We get g(x)=2(5x+1)+5 Distribute the 2 to 5x and 1.
g(x)=10x+2+5
Simplify to get g(x)=10x+7
Now, we plug in -1 for x.
g(-1)=10(-1)+7
g(-1)=-10+7
g(-1)=-3

Evaluate 15r -1 when r=5
alukav5142 [94]

Answer:

74

Step-by-step explanation:

You just have to substitute r with 5.

Now, the equation looks like this:

15(5)-1

Next, solve 15*5 first according to PEMDAS

And 15*5 equals 75

\frac{\left[\begin{array}{ccc}1&5\\5\\\end{array}\right] }{75}

Lastly, do 75-1 which equals 74

\frac{\left[\begin{array}{ccc}7&5\\-1\\\end{array}\right] }{74}

Therefore, 74 is your answer.
