How do you find X and Y intercepts

Mathematics
2 answers:
NeTakaya3 years ago

The x intercept is when the line crosses the x axis
   the place where the line crosses the x axis is also when y=0
the y intercept is when the line crosses the y axis
   the place where the line crosses the y axis is also when x=0

so lets say you have the equation in slope-intercept form
which is y=mx+b

m=slope
b=y-intercept

to find the x intercept, set y to zero and solve
to find the y intercept, find b or set x to zero and solve (which cancels out mx and leaves b)

so exg
y=3x+4
x intercept=y=0 so 0=3x+4
subtract 4 from both sides
-4=3x
divide boht sides by 3
-4/3=x intercept


so y intercept
y=3(0)+4
y=0+4
y=4=y intercept

X and Y intercepts are when a function crosses the x or y axis. 
x-intercepts are at (x-value, 0) and y-intercepts are at (0, y-value).

To find the place where a function crosses the x or y axis, you must plug zero in for the opposit variable. This means plugging in 0 in the equation for y when you try to find x-intercepts and 0 in for x when you try to find y-intercepts, and then solve.

EX. the simple linear equation y = 4x + 2

find the x-intercept: 0 = 4x +2 
                             -2      -2
                              ------------
                                  4
(-.5, 0)

find the y-intercept: y = 4(0) +2
                                  y= 2 
(0,2)

How many terms are there in a geometric series if the first term is 3, the common ratio is 4, and the sum of the series is 1,023
tatiyna
In Geometric Progression, we know S(n) = a.(rⁿ - 1 ) / r - 1
Here, a = 3, r = 4 a(n) = 1,023
1023 = 3 (4ⁿ - 1) / (4 - 1)
3(4ⁿ - 1) = 1023 * 3
4ⁿ - 1 = 3069 / 3
4ⁿ = 1023 + 1
4ⁿ = 1024
4⁵ = 1024

In short, Your Answer would be 5 Terms

Hope this helps!

lesantik [10]

Answer:

polynomial is one. Because the zeros of a polynomial can be determined from the factors of a polynomial, the factors can be created from the zeros. For the zero which occurs at 2, 3 x x = -2/3, the factor which produced that zero is 2. 3 x §· ¨¸ ©¹ The multiplicity represents how many times that zero occurs, in other words, the degree of ...

ANSWER FOR BRAINLIEST<br> Identify the graph for the point C(−2, −1, 2) in three-dimensional space.
ioda

Answer:

the topmost one maybe?

Step-by-step explanation:

I'm guessing since X & Y are negative, (it's written X,Y,Z, right?)

The point would be reducing on the X&Y axes, an since Z is positive, it would increase on the Z axis
