Answer:
-8
Step-by-step explanation:
you need to rewrite it in y=mx+b form where b-is the y-intercept
y-4= -3(x+4)
distribute
y-4 = -3x-12
isolate y
y= -3x-8
compare this with the y=mx+b so y-intercept is -8
Answer:
The slope is -1/8 and the y intercept is 7/6
Step-by-step explanation:
This equation is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -1/8 x + 7/6
The slope is -1/8 and the y intercept is 7/6
Answer:
The number of white horses is 52
Step-by-step explanation:
Let
x ----> the number of black horses
y ----> the number of white horses
we know that
----> equation A

----> equation B
Substitute equation B in equation A and solve for y

therefore
The number of white horses is 52
f(x) should be in canonical form. So it must have the form

Where a is the main coefficient and is the vertex
Step-by-step explanation:
A quadratic function has a unique extreme value in its vertex. That value might be a maximum or a minimum depending on the sign of the main coefficient of the quadratic function. In order to quickly obtain the vertex, the quadratic must be written in canonical form. That means that f(x) must have the form

Where a is the main coefficient (which should be negative so that a minimum exists in the first place) and is the vertex. If f(x) is written in that form, then it will be easier to find the minimum of f(x), which is the vertex
Hence for the quadratic function below

Hence there is only one x- intercept and answer is (2, -9)
