What is the -x intercept and y-intercept of y=-2x+4

1 answer:

4 0

To find x intercept, you must set the y value equal to zero
0= -2x+4
Subtract 4
-4= -2x
Divide by -2
x=-4/-2= 4/2= 2
The x intercept is 2

To find the y intercept, you must set the x value equal to zero
y= -2(0)+4
y=4
The y intercept is 4

If angle 1 and angle 5 are vertical angles and angle 1 equals 55, then angle 5 will equal ______.

Ainat [17]

Hey there, and good morning to you! :D

Vertical Angles are angles that are congruent and have the same measure, and they usually form a straight line through the vertex. (if you were to draw through them) They actually share the same vertex.

So if angle 1 and angle 5 are vertical angles, and angle 1 equals 55 degrees,

then angle 5 will equal 55 degrees.

I hope this helps!

What is the height of a triangle whose base is 8.6 centimeters and whose area is 79.12 square centimeters? round to the nearest

Nezavi [6.7K]

Answer:

height = 18.4 cm

Step-by-step explanation:

A = (1/2)*b*h

A = 79.12 sq. cm = (1/2)* 8.6 * h

A = 79.12 sq. cm = 4.3 * h

h = 79.12 / 4.3 = 18.4 cm
