-1/3b = 9
b = 9 * -3
b = -27

−1/3b=9
Divide -1/3 on both sides
b= 9 divided by -1/3
Convert the 9 into an improper fraction
b= 9/1 divided by -1/3
Convert the division sign to multiplication while flipping the fraction -1/3 to -3/1
b= 9/1*-3/1
Multiply
Final Answer: b = -27

Al, Pablo, and Marsha shared the driving on a 1,500-mile trip. Which of the three drove the greatest distance on the trip?(1) Al

Svetach [21]

Answer:

Pablo drove the greatest distance of 527 miles.

Missing Content:

Since information on Pablo is not given, it is impossible to solve this problem. Let us assume some scenario for Pablo. Say:

(3)Pablo averaged 52.7 miles per hour and drove for 10 hours.

Step-by-step explanation:

Using this information, we can find out the data on Al,

Al drove 1 hour longer than Pablo so,

Time Al drove= 10+1 =11 hours

Average rate of Al=Pablo's average rate-5= 52.7-5 = 47.7 miles per hour.

We know that,

Average Speed = $\frac{Distance}{Time}$

Distance =Average Speed x Time

Distance travelled by Al = 47.7 x 11 =524.7 miles

Distance Travelled by Marsha = 50 x 9=450 miles

Distance Travelled by Pablo= 52.7 x 10= 527 miles

As we can see that Pablo drove the greatest distance which is 527 miles.

Find the distance between the points (3, –8) and (0, –9).

Oksanka [162]

Answer:

B. 3.16

Step-by-step explanation:

1) formula of the required distance is:
$d=\sqrt{(X_A-X_B)^2+(Y_A-Y_B)^2} ;$

2) if A(3;-8) and B(0;-9), then according to the formula above:

$d=\sqrt{(0-3)^2+(-9+8)^2} =\sqrt{10}.$

d≈3.16

Graph the function. y = 2x^2 + 4x

rodikova [14]

Answer:

Step-by-step explanation:

The function y = 2x^2 + 4x has a parabolic graph that opens up.

*In factored form we have y = 2x(x + 2); if we set this equal to zero and solve for x, we obtain {-2, 0}, the roots of this function.

*The axis of symmetry is halfway between these roots: x = -1. The y-value of the vertex is the value of the function at x = -1: f(-1) = 2(-1)^2 + 4(-2) = -6. Thus, the vertex is (-1, -6).

* The y-intercept is (0, 0), since y = 0 when x = 0.

Graph the points shown and draw a smooth curve through them, remembering that this parabola opens up.

Help me with this question, please.

Tomtit [17]

Answer:

I will do one of them and explain so you can do the rest

an 80% increase followed by a 40% decrease.

since the increase is greater than the decrease (80>40) it would go into the greater than original group since it has been increased.
