(0,-4) , (8,4) writing equations in slope intercept form write an equation of each line that passes through the given points answers please

Answers

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

Which of the equations are true identities? A. (x-2y)^2=x^2-4xy+4y^2 B. (m+1)^2-m^2=1

Question 2
Find the slope of a line that passes through the given points.
(-8, -11) and (17, 4)

Answers

Answer:

slope = 0.6

Step-by-step explanation:

If a-b, a+b are the zeros of x^2-4x+3 then (a, b) =
A) (3, 1)
B) (-3,-1)
C) (2, 1)
D) (-2,-1)

Answers

Given:

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

Find:

The coordinates of (a,b)

Solution:

(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.

Answer:

discriminant: -232 complex solutions

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.

Ut 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.

Answers

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]

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.

Answers

Answer:

£76.904

Step-by-step explanation:

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

One pipe can fill a tank in 8 minutes. A second can fill it in 12 minutes, and a third can fill it in 24 minutes. If the tank is empty, how long will it take the three pipes, operating together, to fill it?

Answers

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,
