HELP MY RSM CLASS IS TOMORROW

Graph the lines given by the following equations:

y=3-1/2x

Answer:

£76.904

Step-by-step explanation:

Lsat month, harri drove 850 miles in his car. his car's fuel consumption is 45.6 miles per gallon. petrol cost £1.09 per litre. given that 8pints = 1gallon, work out how much Harri spent on fuel last month. You must show working out.

a) 45.6 miles per gallon

45.6 miles = 1 gallon

850 miles = x

Cross Multiply

x = 850/45.6

x = 18.640350877 gallons

b) 8pints = 1gallon,

8 pints = 3.785 litres

1 gallon = 3.785 litree

18.640350877 gallons = y

Cross Multiply

18.640350877 litres × 3.785

= 70.5537280694 gallons

c) 1 litres = £1.09

70.5537280694 litres = z

Cross Multiply

z = 70.5537280694 × £ 1.09

z = £76.9035635957

Approximately = £76.904

Answer:

Your answer would be C. K = 3

Step-by-step explanation:

Answer:

your answer should be three

Step-by-step explanation:

12 divided by 4 equals 3

Answer: C

Step-by-step explanation:

9514 1404 393

Answer:

Step-by-step explanation:

Compare the equations ...

  ax² +bx +c = 0

  x² -x +6 = 0

and you can see that the values of a, b, c are ...

  a = 1, b = -1, c = 6

Putting these values into the expression for the discriminant, ...

  d = b² -4ac

we have ...

  d = (-1)² -4(1)(6) = 1 -24 = -23

The discriminant is -23.

__

The interpretation of the discriminant is ...

  negative -- 2 complex solutions

  zero -- one real solution

  positive -- 2 real solutions

Here, the discriminant is negative, so ...

The equation has 2 complex solutions.

Answer:

This is a trick answer but the answer is 24 minutes

Step-by-step explanation:

They have already added up the time and its 24 if you read 1 is 8 the second is 12 and 3 pipes are 24

Also lemme get brainlist

Answer:

4.8 min (4 min 48 seconds)

Step-by-step explanation:

In one minute:

Pipe A fills the tank 1/8th full

Pipe B fills the tank 1/12 full

Pipe C fills the tank 1/24th full

1/8 + 1/12 + 1/24 = 5/24

So the the at which they will fill the tank is 24/5,

or 4.8 minutes (4 minutes 48 seconds)

How to solve the addition of integers?

To add integers having the same sign, keep the same sign, and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

How to solve the subtraction of integers?

To subtract integers, change the sign on the integer that is to be subtracted. If both signs are positive, the answer will be positive. If both signs are negative, the answer will be negative. If the signs are different subtract the smaller absolute value from the larger absolute value.

α - β , α + β are the zeroes of x² - 4x + 3.

The coordinates of (a,b)

(Let a = α & b = β).

On comparing with standard form of a quadratic equation i.e., ax² + bx + c = 0 ;

Let ;

a = 1

b = - 4

c = 3.

We know that,Sum of the zeroes = - b/a

⟹ α - β + α + β = - ( - 4)/1

⟹ 2α = 4

⟹ α = 4/2

⟹ α = 2

And,

Product of the zeroes = c/a

⟹ (α - β) * (α + β) = 3/1

(a + b) * (a - b) = a² - b².

⟹ α² - β² = 3

Putting the value of α we get,

⟹ (2)² - β² = 3

⟹ 4 - 3 = β²

⟹ 1 = β²

⟹ √1 = β

⟹ 1 = β

∴(a , b) = (α , β) = (2 , 1). (Option - C).

I hope it will help you.

Regards.

Answer:

Siso your answer refer in pic

Answer: (5,0)

Step-by-step explanation:

You could remove this one, because for each input (x) there can only be 1 output (y)

So by removing (5,0) this becomes a function. 5 only has one output now, (3)

Answer:

the answer is 1

for example, 1÷1 equals one. a number that is the same divided is always 1. another example. 2÷2 is 1.

Answer: The answer is 1

Step-by-step explanation:Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

149×914=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

14×99×14=126126

Since 126 divided by 126 equals 1 then,

126126=1

Therefore:

149÷149=1

Solution by FormulasApply the fractions formula for division, to

149÷149

and solve

14×99×14

=126126

=1

Therefore:

149÷149=1

Answer:

0.5806

Step-by-step explanation:

Out of a group of 145 students that were surveyed about sports, 31 said they play basketball and 59 said they play soccer. 18 of the students who said they play basketball said they also play soccer. If a student is chosen at random, find the probability. P (Soccer |Basketball).

Solution:

P(soccer) = number of students playing soccer/ total number of students.

P(soccer) = 59/145

P(basketball) = number of students playing basketball/ total number of students.

P(basketball) = 31/145

P(soccer and basketball) = number of students playing soccer and basketball/ total number of students.

P(soccer and basketball) = 18/145

From Bayes theorem:

P(A | B) = P(A ∩ B) / P(B)

Hence:

[tex]P(soccer|basketball)=\frac{P(soccer\cap baketball)}{P(basketball)}=\frac{\frac{18}{145} }{\frac{31}{145} } =0.5806[/tex]

Answer:

y = x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (8, 4)

m = [tex]\frac{4+4}{8-0}[/tex] = [tex]\frac{8}{8}[/tex] = 1

The line crosses the y- axis at (0, - 4 ) ⇒ c = - 4

y = x - 4 ← equation of line

Answer:

2315.6 (Fraction= 2315 3/5)

Step-by-step explanation:

2312.2 (2312 1/5) + 3.4 (3 2/5) = 2315.6 (2315 3/5)

Complete question :

The play director 190 hours preparing for a plane that time include attending 35 rehearsals that took varying amount of time in spending 93 3/4 hours on the other responsibilities related to the play. What question does the equation 3/5 x + 93 3/4 equal 190 help answer? A. How much longer did the director spend on rehearsals and on other responsibilities? B. What was the average length of each rehearsal? C. How long was each rehearsal?

Answer: C. How long was each rehearsal?

Step-by-step explanation:

Total time spent preparing for play = 790 hours

Of the 190 hours :

Number of rehearsals = 35

Others = 93 3/4 hours

What question does the equation 35 x + 93 3/4 equal 190

35x + 93 3/4 = 190

(Number of rehearsals) * x + others = total time

x = time spent on each rehearsal

35x = 190 - 93 3/4

35x = 96.25

x = 96.25 / 35

x = 2.75 hours

Each rehearsal took 2.75 hours
