y=−2x−5
y=2x−2 ​

Answers

Answer 1

Answer:

(-3/4, -7/2)

Step-by-step explanation:

y= −2x − 5

y= 2x − 2

2y = -7

y = -7/2

y= 2x − 2

-7/2 = 2x - 2

2x = -3/2

x = -3/4

(x,y) = (-3/4, -7/2)

Answer 2

Answer:

-3/4 or -7/2

Which number is an irrational number?
A.) 3.5
B.) √36
C.) √48
D.) 37/100

Answers

A because the others are fractions and not a whole number

Answer:

the answer is c

Step-by-step explanation:

square root of 36 = 6 = 6 / 1D. 37 / 100 is already a fraction. Hence, the only number that cannot be written as a fraction is the square root of 48. The answer is C: the square root of 48 is an irrational number.

A bag contains 2 black balls, 4 yellow balls and 4 white balls. Event A is defined as drawing a white ball on the first draw and event B is defined as drawing a black ball on the second draw. If two balls are drawn from the bag, one after the other and not replaced, what is P(B|A) expressed in simplest form? A. B. C. D.

Answers

Answer: [tex]P(B|A)=\dfrac{4}{9}[/tex]

Step-by-step explanation:

Given: A bag contains 2 black balls, 4 yellow balls and 4 white balls.

Event A is defined as drawing a white ball on the first draw.

Event B is defined as drawing a black ball on the second draw.

P(B|A) is expressed as the conditional probability of occurring B given that A.

i.e. it is the probability of happening B where A is already happended.

If a white ball is drawn at first, then the number of black ball(4) remains unchanged but the total number of balls (10) will become 9.

[tex]Probability=\dfrac{Number\ of \ favorable \ outcomes}{Total\ outcomes}[/tex]

Then, [tex]P(B|A)=\dfrac{4}{9}[/tex]

Emma's dad is a police officer. One

speeding, which was 12 more than the
previous day and 7 more than the day
before that. How many people did
Emma's dad stop for speeding during
that three-day period?

Answers

The answer is
19 - 12 is 7
19 - 7 is 12
And he stopped 19 today
He stopped 38 people’s in a 3 days periods

Answer:

Let's say he stopped 19 people on Wednesday.

Wed - 19 people stopped

Tues - 19-12 is 7, so he saved 7 people that day

Mon - 19-7 is 12. so 12 people stopped on monday

so in all (including Wednesday) he stopped 38 people

Substitution:
X + 2y = 13
-2x - 3y = -18

Answers

Answer:

x = -3

y = 8

Step-by-step explanation:

x + 2y = 13    ------------(I)

    x  = 13 - 2y -----------(II)

-2x - 3y = -18 ----------(III)

Substitute x = 13 - 2y in equation (III)

   -2*(13 - 2y)  - 3y = -18

-2*13 - 2y *(-2) -3y = -18

  -26  + 4y  - 3y    = -18             {Combine like terms}

               -26 + y =  -18     {Add 26 to both sides}

                         y = -18 + 26

                         y = 8

Substitute y = 8 in equation (II)

x = 13 - 2*8

  = 13 - 16

x = -3

x = -3

y = 8

Sturdy’s paper plates cost $3.12 for 24 plates. Tough’s paper plates cost $4.32 for 32 plates. Which is the better buy?

Answers

Answer:

Sturdy's paper plates

Step-by-step explanation:

Let's see how much 8 plates cost:

Sturdy

24/3=8

$3.12/3= $1.04

Tough

32/4=8

$4.32/4=$1.08

$1.04<$1.08

Because Tough's paper plates costs 4 cents more for 8 plates, Sturdy's paper plates are the better buy.
