Answer:

The constant of proportionality is 0.3

Step-by-step explanation:

» The graph shows a direct proportiinality.

{ \rm{y \:   \alpha \: x}}

» Therefore, input the constant;

{ \rm{y = kx}}

» When x is 5, y is 1.5:

{ \tt{1.5 = (k \times 5)}} \\ { \rm{k = 0.3}}

Answer:

0.3

Step-by-step explanation:

On a graph, proportional relationships are straight lines that extend through the origin.  

Slope of a graph = constant of proportionality of the equation

Let (5, 1.5) = (x_1,y_1)

Let (20, 6) = (x_2,y_2)

Formula of a slope: m=\dfrac{y_2-y_1}{x_2-x_1}

\implies m=\dfrac{6-1.5}{20-5}=0.3

So as the slope = 0.3, the constant of proportionality = 0.3

1. Find p(-3) if p(x) = 4x3 - 5x2 + 7x - 10
SVETLANKA909090 [29]

Answer:

1) -184

2) 13(m^{4}) ^{2}-3(m^{4})+4

Step-by-step explanation:

For problem number 1, Let's start by substituting all the x's for -3

So the equation will look like

p(-3)=4(-3)^{3}-5(-3)^{2}+7(-3)-10

Now, lets simplify by solving the exponents

First we'll do -3^{3} which equals -27

Now we'll do -3^{2} which equals 9

So now our equation looks like

p(-3)=4(-27)-5(9)+7(-3)-10

Now, we are going to multiply all these numbers

First 4(-27) which equals -108

Now -5(9) which equals -45

And finally 7(-3) which equals -21

Now our equation looks like

p(-3)= -108-45-21-10

Now we can solve

-108-45-21-10=-184

Answer:

x = -4

Step-by-step explanation:

-5x-4x-2 = -8x+2 is the only one with a solution.

How do i do this some one please explain
Talja [164]

Well since we already have our unit per mile.

We know that 1 mile = $3.50

And that the tow company towed the car 12 miles.

So we would have to multiply 12 by $3.50

soo..

12 x $3.50 = $42.00

So your answer is D. $42.00
