3. What is the value of x + y?

Mathematics
1 answer:
MrMuchimi2 years ago

Answer:

y = 50 x = 10.

Step-by-step explanation:

Let's solve for y first.

We know the line angle 80 and angle 2y-5 is on a 180 degree line.

Now we can do our work:

180 - 85 = 95

2y - 5 = 95

95 + 5 = 100

100 ÷ 2 = 50

2(50) - 5 = 95?

The equation is correct, therefore y = 50.

No we do the same thing for the other angles, 90 and 3x + 55.

Again, 180 line.

180 - 95 = 85

3x + 55 = 85

85 - 55 = 30

30 ÷ 3 = 10

3(10) + 55 = 85?

The equation is correct therefore x = 10.

Thus, y = 50 and x = 10.

What is the solution to the equation ?
Savatey [412]

Answer:

There is no solution of the system of equations.

Step-by-step explanation:

We are given two equations y = - 4 and y = 4 and are to find the solution to the equations.

Now, the straight line y = - 4 is parallel to the x-axis as the equation of straight lines that are parallel to the x-axis are given by y = c, where c is any constant value.

Again, the straight line y = 4 is parallel to the x-axis.

Therefore, y = - 4 and y = 4 two lines are parallel to each other and we know, parallel lines never intersect and hence there is no solution of the system of equations. (Answer)

"What is the y-intercept of the line that has a slope of- 4 and passes through the point (A)- 10 (B)-6 (C) 8 (D) 10​
jarptica [38.1K]

The y-intercept which is the point at which x = 0 is; A: -10

<h3>How to find the y-intercept?</h3>

The general form of an equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

We are given the slope;

m = -4

Now, the line passes through the point 0, -10. Thus;

(y - y1)/(x - x1) = -4

(y + 10)/(x - 0) = -4

y + 10 = -4x

y = -4x - 10

Thus, the y-intercept which is the point at which x = 0 is; y = -10
