Basically f(a) is your y and a is your x. The question is asking you what would your “y” be if your “x” is 0. If you plug 0 into the a, you would multiply 5•0 which would leave you with positive 14.
f(a)=5a+14
so basically y=5x+14 and x=0
plug in 0 for your x
y=0

Answer:

a = 14

Step-by-step explanation:

<u>Step 1: Write out your problem</u>

f (a) = 5a + 14 | f (a) = 0

<u>Step 2: Solve</u>

f (a) = 5 (0) + 14 , Input a.

f (a) = 0 + 14 , 5 x 0 = 0

(a) = 14 , 0 + 14

a = 14

A card is drawn from a well-shuffled deck of 52 cards. What is the probability that a red card appears?
Vinil7 [7]

<u>Answer:</u>

P (red) = 1/2

<u>Step-by-step explanation:</u>

It is given that a card is drawn from a well-shuffled deck of 52 cards and we are to find the probability of getting a red card.

We know that there are total 26 red cards in a deck (13 hearts and 13 diamonds).

Therefore, the probability of getting a red card P (red) = \frac { 2 6 } { 5 2 } = 1/2

I need help ASAP! And work needs to be shown!
spin [16.1K]

Answer:

32 x p/100 = 40

(Solve for P)

Multiply by 100 on both sides

32x = 4,000

Divide by 32 to get:

X = 125%

(reason why you multiply by 100 is because opposite of division is multiplication and we multiply the number "100" because we always multiply the denominator to both sides when having a fraction so you can solve for p or whatever. And that means p/100 x 100 it means p because since p is not a known value we consider 1/100 x 100 = 1, a variable by itself means 1 so you could just put p by itself next to the number its multiplied by which is 32 so it would be 32p because your multiplying both and the opposite of that would be dividing by 32 on both sides because you are getting rid of the 32 so therefore you will be left with: X = 125)

Sarita showed the steps to solving the equation. 5 (x minus 3) + 7 (x + 4) = 73 Steps Sarita’s Solution Sarita’s Verification 1
Usimov [2.4K]

Answer: First option.

Step-by-step explanation:

The complete exercise is attached.

Given the following equation:

5 (x-3) + 7 (x + 4) = 73

The steps to solve it are:

1. Apply the Distributive property:

5x-15+7x+28=73

2. Add the like terms:

12x+13=73

3. Subtract5 13 from both sides of the equation:

12x+13-(13)=73-(13)\\\\12x=60\\\\

4. Divide both sides of the equation by 12:

\frac{12x}{12}=\frac{60}{12}\\\\x=5

To verify it, let's substitute x=5 into the equation:

5 (5-3) + 7 (5 + 4) = 73

Evaluating, we get:

5 (2) + 7 (9) = 73\\\\10+63=73\\\\73=73

Based on this, we can determine that Sarita's solution is correct, but she made an error in her verification (Observe that  5-3\neq -2)
