Answer:
x < 7
Step-by-step explanation:
the domain of a function defines the valid x values for the function.
as we go from left to right through all possible values of x, we see all values incl. x=-1 are creating a valid function result (y) for this function. until we reach x=7.
the empty ball indicates that there is no y value defined here. and for any value x>7 there is no y value defined.
so, x < 7 is the right one.
Answer:
In your equation 4x+5y=-9, you've got to but your equation in slope intercept form which is y=mx+b.
First we need to get the y by itself.
Subtract 4x from each side to get:
5y=-4x-9
Next we want to divide both sides by 5.
y=-4/5x-9/5
Your slope is m which in our case -4/5.
Then our y-intercept is b or -9/5.
Your answer would then be C. slope=-4/5 and y-intercept=-9/5.
Hope this helps ;)
Answer:
around 2.31
Step-by-step explanation:
because you will get 2.307 if you put it in a calculator then you can round it to 2.31
ANSWER
EXPLANATION
We want to find the equation of the straight line given on the graph.
The general form of a linear equation is given as:
where m = slope; b = y-intercept
To find the slope, we apply the formula for slope:
where (x1, y1) and (x2, y2) are two points on the line
Let us pick (1,2) and (4,4)
Therefore, the slope is:
To find the equation, we now apply the point-slope formula:
Therefore, we have that the equation of the line is:
That is the equation of the line.
Step-by-step explanation:
1.) Move the 5 to the other side of the equation
8y = -5x + 31
2.)
Divide by 8
y= .625x + 3.8
