Answer:
12x-84y+24z
Step-by-step explanation:
Answer:

Step-by-step explanation:
Given


Required
Find XY
Represent BC and XY as a ratio;

Recall that:

Equate both ratios;

Convert to fractions

Cross Multiply


Divide through by 3


Hence:

Yes, f(x) = 16 - 7x is a linear function because there are no exponents and the rate of change (which is the slope) only adds or subtracts a certain number each time.
Answer:
y-intercept is (0, -4)
x-intercept is (-5, 0)
Step-by-step explanation:
Remember the x-intercept and the y-intercept are the points on the graph where the line crosses the x-axis and the y-axis respectively.
We can find the x intercept and the y intercept a couple of ways. One way is to graph the line, which I will do later. The other way is to do a little math.
The equation of a line in y-intercept form is

where b = the y-intercept
In our equation above and solving for y we get the y-intercept is -4

Doing more algebra and solving for x we get the x intercept is negative 5.
