Answer:
y = 
+ 5
Step-by-step explanation:
So here we have to put it in y = mx + b form;
7x + 4y = 20
Subtract 7x from both sides;
4y = -7x + 20
Divide both sides by 4;
y = + 5
Answer:
(3,5,4)
Step-by-step explanation:
For x, y, z axis plots, we see how many units it goes in x direction(front/back), how many units in y(right/left) direction, and how many units in z direction (up/down).
Looking at the graph, we see that point goes in x-direction 3 units positive, so x point is +3.
Also, looking at y-direction, it goes 5 units to the right, which is +5 units. So y = +5
Then, the point then goes UP (which is positive z direction) 4 units, so that's z = +4
The ordered triple is (3,5,4)
2nd answer choice is right
Answer:
m=-1
Step-by-step explanation:
9m+13 =4
Subtract 13 from each side
9m+13-13 =4-13
9m = -9
Divide each side by 9
9m/9 = -9/9
m = -1

Answer:
-1<x<1 and 1<x
Step-by-step explanation:
We are asked to determine the interval in which our function shown in the graph has positive values.
In order to do so, we have to see for what values of x on x axis, the graph is above x axis.
As we can see in the graph, when we move from x = -1 towards right, the graph is above x axis. And towards left of x=-1 , the graph is below x axis. Hence answer is
-1<x<1 and 1<x
