Step-by-step explanation:

When mapping a function the inputs (x), the oval to the left, is the domain. The oval to the right, the output, is the range.

since the equation of the line passing through the given point is perpendicular to the given line(m2= -1/m1)

using the formula y=mx+c

y=2/3x +1

m1=2/3

m2= -1/2/3

m2= -3/2

the slope of the second line is -3/2 and it passes through the point(3,-2)

using the formula y-y1 = m(x-x1)

y-(-2)= -3/2(x-3)

y+2= -3/2(x-3)

multiply both sides by 2

2(y+2) = -3(x-3)

2y+4 = -3x+9

2y = -3x+5

y= -3/2x + 5/2

Answer:

It is given

4x+3y=24

We can also write it as

3y=24−4x

 y=324−4x

Substituting x=0 in the given equation

 y=324−4(0)

 So we get 

 y=324

 By division 

 y=8 

 Substituting x=3 in the given equation 

 y=324−4(3)

 So we get

 y=312

 BY division 

 y=4

= 1.5

θ =

arctan( ΔY )

ΔX

= 56.30993247402°

ΔX = 4 – 2 = 2

ΔY = 8 – 5 = 3

Distance (d) = √ΔX2 + ΔY2 = √13 = 3.605551275464

y = 1.5x + 2

Step-by-step explanation: just looked it up

In probabilities, variables p and q are often used as complements of another.

The relationship between variables p and q is:

[tex]\mathbf{p+ q = 1}[/tex]

So, we have:

(a) p = 0.579

Substitute 0.579 for p in [tex]\mathbf{p+ q = 1}[/tex]

[tex]\mathbf{0.579 + q = 1}[/tex]

Make q the subject

[tex]\mathbf{q = 1 - 0.579}[/tex]

[tex]\mathbf{q = 0.421}[/tex]

The value of q is 0.421

(b) q = 0.871

Substitute 0.871 for q in [tex]\mathbf{p+ q = 1}[/tex]

[tex]\mathbf{p + 0.871 = 1}[/tex]

Make p the subject

[tex]\mathbf{p = 1 - 0.871}[/tex]

[tex]\mathbf{p = 0.129}[/tex]

The value of p is 0.129

Answer:

600 cubic feet

Step-by-step explanation:

We want to create a linear equation to model the given situation.

A) c(r) = $6.00 + $1.50*r

B) 19 rides.

We know that the carnival charges $6.00 for entry plus $1.50 for each ride.

A) With the given information we can see that if you ride for r rides, then the cost equation will be:

c(r) = $6.00 + $1.50*r

Where c(r) is the cost for going to the carnival and doing r rides.

B) If you have $35.00, then we can solve:

c(r) = $35.00 =  $6.00 + $1.50*r

Now we can solve the equation for r.

$35.00 =  $6.00 + $1.50*r

$35.00 -  $6.00 = $1.50*r

$29.00 = $1.50*r

$29.00/$1.50 = r = 19.33

Rounding to the next whole number we get: r = 19

This means that with $35.00, Dennis could go to 19 rides.
