Best way to find the intercept of 15x-12y=60, or of any line for that matter, is to put it into slope intercept form y=mx+b, where m is the slope and b is the y intercept
to do this we will need some equation manipulation to get it = to y
15x-12y=60
(15x-12y)+12y=(60)+12y
15x=60+12y
(15x)-60=(60+12y)-60
15x-60=12y
(15x-60)/12=(12y)/12
(5/4)x-5=y
y=(5/4)x-5
so m = 5/4 and b = -5
Final answer:
The y-intercept is at (0,-5)

Answer:
First question (first two pictures): The answer is the option on the second page, at the bottom.
Second question (last three pictures): The answer is A.
Step-by-step explanation:
Answer:
(1,-5)
Step-by-step explanation:
recall that for any function g(x), we can equate the function to y,
i.e y = g(x), where any point (x,y) that satisfies the equation is considered a point on the graph
in our case we are given, that g(1) = -5, rearranging:
-5 = g(1)
if we compare this with the the equation above y = g(x),
we can see clearly that y = -5 and x = 1.
and from our reasoning given in the paragraph above, we can say that (1,-5) is a point on the graph.
Answer:
B) 6 units
Step-by-step explanation:
The formula of the volume of the Pyramid is 1/3×area of the base×height
1/3×70×height=140
Dividing both sides by 70
1/3×height=2
Multiplying both sides by 3
Height = 6
what I know is that 12 is less than 300 and divisible by 12/3=4, and12/4=3
