Answer 1
Answer: so F(m) because F dollars for every mph over the speed limit
so 40 dollar speeding fine so +40 
10 dollars for every mile over and m=miles over so put them all toghether and get
F(m)=10m+40


1.
so if you were going 78 mph
to find the mph over you would do 78-70=8mph over so put in 8 for m and get
F(8)=10(8)+40=80+40=$120 fine for going at 78 mph

-(4x - 7) + 1 = 2 (5 - 2x) solve for x

Answers

Answer:

No solution

Step-by-step explanation:

-(4x - 7) + 1 = 2(5 - 2x)

-4x + 7 + 1 = 10 - 4x

-4x + 8 = 10 - 4x

-4x + 8 ≠ -4x + 10

Write the equation in slope-intercept form. y−2=−4/3(x+6)

Answers

Answer: y = -4/3x - 6

Step-by-step explanation: To write the equation in slope-intercept form, we need to solve for y.

Starting with the given equation: y - 2 = -4/3(x + 6)

First, distribute -4/3 to both terms within the parentheses: y - 2 = -4/3x - 8

Next, isolate y by adding 2 to both sides of the equation: y = -4/3x - 8 + 2

Simplifying further: y = -4/3x - 6

Therefore, the equation in slope-intercept form is y = -4/3x - 6.

There are 15 cards, numbered 1 through 15. If you pick a card, what is the probability that you choose an odd number or a two?A)
2
3

B)
3
5


C)
8
15


D)
8
225

Answers

Answer:

Option B

Step-by-step explanation:

Given that the 15 cards are numbered 1 to 15.

A card is picked at random.  We have to find the probability that the card is odd or two

Let A - selected card is odd

B - selected card is 2

A and B are mutually exclusive

Hence P(AUB) = P(A)+P(B)

Since there are 1,3....15 i.e. 8 odd numbered cards

P(A) = 8/15

P(B) = 1/15 (since there is only one two)

Thus required prob = P(AUB) = 8/15+1/15

=9/15

=3/5

Hence option B

There are 8 odd number between 1 and 15 (1,3,5,7,9,11,13,15), so the probability of choosing an odd number is (8)/(15).

The probability of choosing 2 is (1)/(15).

So, the overall probability is equal to (8)/(15)+(1)/(15)=(9)/(15)=(3)/(5)
