What are the x-intercept and y-intercept of the graph of y=−12x+4

1 answer:

5 0

The x intercept is where the line crosses the x axis or where y=0
the y intercept is where the line crosses the y axis or where x=0

xintercept
set y=0 and solve for x
0=-12x+4
add 12x both sides
12x=4
divide by 12
x=1/3
the x intercept is 1/3
not listed so I assume it is y=-1/2x+4, which yeilds x=-2

x intercept
using y=-1/2x+4
set x=0
y=-1/2(0)+4
y=0+4
y=4
y intercept is 4

assumign you forgot the slash to make the fraction to make
y=-1/2x+4

x intercept is -2
y intercept is 4

If BA [a= (-2,-3) b= (1,2)] is extended all the way through A creating a BF and A becomes the midpoint of BF, then what are the

Irina18 [472]

Answer:

(-5,-8)

Step-by-step explanation:

If M(x,y) is the midpoint of the segment CD, where $C(x_1,y_1),\ D(x_2,y_2),$ then

$x=\dfrac{x_1+x_2}{2}\\ \\y=\dfrac{y_1+y_2}{2}$

You are given two points A(-2,-3) and B(1,2), let point F be the point with coordinates (x,y). Yuo know, that point A is the midpoint of BF, then

$x_A=\dfrac{x_B+x_F}{2}\\ \\y_A=\dfrac{y_B+y_F}{2}$

Substitute known coordinates:

$-2=\dfrac{1+x}{2}\Rightarrow 1+x=-4,\ \ x=-5\\ \\-3=\dfrac{2+y}{2}\Rightarrow 2+y=-6,\ \ y=-8$

So, point F has coordinates (-5,-8)

Answer X=-2

-3x - 15=9
-3x= -9 + 15
-9 + 15= 6
-3x = 6
x= -6/3
x= -2
answer x=-2
sorry if this wasn’t the best explanation i’m kinda rushing rn bc of class

Answer:

x = 18

Step-by-step explanation:

The given angle is a right-angled triangle.

Such triangles have an angle that equals 90°.

The square attached at the base represents 90°. [Whenever you such a square between two sides, simply put the angle between those sides equal to 90.]

So, the points we know about this triangle:

One angle is = 90
Another angle given in the question is 72°.

*Property*

The sum of all angles in a triangle = 180

==> 90 + 72 + x = 180

==> 162 + x = 180

==> x = 180 - 162

==> x = 18
