Take the original equation, substitute x for 22, and use PEMDAS to solve.

f(x) = 2x - 5
f(x) = 2(22) - 5
f(x) = 44 - 5
f(x) = 39

Your final answer will be 39.

Janette has 386 pennies. 58 nickels and 19 dimes If Janette exchanges her coins for​ dollars, how many dollars will she have? Ho
svet-max [94.6K]

Answer:

$8 ; 66 cents

Step-by-step explanation:

Given that:

Worth of penny, dimes and Nickel in cents and dollars

Nickel, n = 5 cents = $0.05

Dimes, d = 10 cent = $0.1

Penny, p = 1 cent = $0.01

Multiplying the number of each coin with its respective value ;

386(0.01) + 58(0.05) + 19(0.1)

$3.86 + $2.9 + $1.9

= $8.66

Changing it to dollar ,

$8.66 dollars = 8 dollars ;

$0.66 = 66 cents

What is the problem to h-16<24=
ELEN [110]
First, you have to add 16 to both sides because it's the opposite of subtracting.
h-16<24
  +16  +16
-16+16 will cancel each other out.
24+16=40
So, h<40
Or in other words, h is smaller than 40.

Hope it helps ^_^

Which of the statements is true regarding the graphed functions ?
DedPeter [7]
F(x) means the function defined at that x value. It really just means what y value when x is equal to that input. So we can see clearly that A is false. They’re nearly opposite y values. B is also obviously false since the y values aren’t equal. C is the same case, the y values aren’t equal. D is true. When x = -2 for both functions, we can see the y value is the same. They also intercept, so that’s a pretty dead giveaway
