Answer:

No

Step-by-step explanation:

-18:8 can be simplified to 9:4

-20:14 can be simplified to 10:7

-9:4 does not equal 10:7

Answer:

No, they're not.

Step-by-step explanation:

You multiply 18×14 which = 252

Then Multiply 8×14 which = 112

(you don't multiply by 20)

It's not equivalent because it doesn't give the same number (252:112) Hope this helps!

Graph the following lines and using the graph determine several values of x for which the graph is positive (negative): y=−4x+3
True [87]

Answer:


Step-by-step explanation:

Given line is,

y=-4x+3

when, x=-1 , y=-4(-1)+3=4+3=7

when, x=0 , y=-4(0)+3=0+3=3

when, x=1 , y=-4(1)+3=-4+3=-1

So, we got the points  (-1,7) , (0,3) , (1,-1)

Now, putting the points in the graph and adding them , we will get the graph of given line.

Please check image for the graph.


Now for the second part-

The graph is positive means- it will be above the x-axis, that is y value will be positive.

From the graph we can see that, if x<0 , then y is positive.

So, any value of x which is less than 0 , will give the positive graph here.
