Answer: -20

Step-by-step explanation: Using the same expression except positive numbers, 4 x 5 = 20.

In this case, we can use this equation to find the product for the expression

4 x -5.

If 4 x 5 = 20, then 4 times -5 will also equal 20. However, since there is a negative factor in this expression, our answer will be negative causing our answer to be <u>-20.</u>

You have to do it like how you do 5x4 you will have to just bring down the - and you will get -20 for your answer

Graph the system of equations on graph paper to answer the question. Y=2/5x+4 and y=2x+12 what is the solution for this system o

riadik2000 [5.3K]

Answer:

Solution of the given equations is (-5,2)

Step-by-step explanation:

We have been given the following system of equations:

y = (2/5)x + 4

y = 2x + 12

The solution of the system of equation can be found by finding the point of intersection of both lines on the graph. The graph of both equations is attached below.

As we can see that both the lines intersect each other at one point, and that point is (-5,2). So the solution of the given equations is (-5,2)

What is 8t^5 times 8t^5?

Ksenya-84 [330]

Well, remember
(ab)(cd)=abcd=(ac)(bd)
so
(8t^5)(8t^5)=(8)(t^5)(8)(t^5)=(8*8)(t^5*t^5)=64t^10

The manager of a gas station has observed that the times required by drivers to fill their car's tank and pay are quite variable

maw [93]

Answer: 0.49

Step-by-step explanation:

The mean= E[x]=1/l= 7.5 min

l=1/7.5 =10/75=2/15

The exponential distribution's probability density function is looking like that:

F(x)= l*e^(-l*x) = 2/15*e^(-2*x/15)

P(0<x<5)= e^(-0*2/15)- e^(-5*2/15)=1- e^(-2/3)= approx 0.49
