If angle 6 is 25 degrees how much is 7
Sindrei [870]

Given:

Angle 6 = 25 degrees

To Find:

The value of Angle 7

Solution:

We know that,

the value of Angle 6 is equal to 25 Degrees

Since Angle 6 and Angle 7 together comprise of a Straight Line, this means that they are Supplementary Angles.

Therefore,

Angle 6 + Angle 7 = 180 degrees

This implies that,

25 degrees + Angle 7 = 180 degrees.     (since Angle 6 = 25 Degrees)  

Angle 7 = (180-25) degrees

Thus ,

Angle 7 = 155 degrees

Hence, Angle 7 is  155 degrees (Option 1)

If you were to graph the linear equation 4x+6y=−12 on the semester test, you would need to determine the x- and y-intercepts, pl
goblinko [34]

The x intercept is -3, and the y intercept is -2

Step-by-step explanation:

The equation given is 4x+6y= -12

Rewrite the equation in slope intercept form of y=mx +c where c is the y intercept

y=mx+c

6y=-4x-12

y= -4/6 x -12/6

y=-2/3x -2

c= -2

To get x intercept replace value of y in the equation with 0;

y= -2/3 x -2

0= -2/3 x -2

2= -2/3 x

2*3=-2x

6=-2x

6/-2 =x

-3 =x

x intercept is -3
