Answer: First option 13
Solution
If ABCD is a rhombus, the diagonals must be perpendicular, then the angle (5x+25)° must be a right angle (90°):
(5x+25)°=90°
5x+25=90
Solving for x: Subtracting 25 both sides of the equation:
5x+25-25=90-25
Subtracting:
5x=65
Dividing both sides of the equation by 5:
5x/5=65/5
Dividing:
x=13
Answer: The value of x must be 13
The answer is 3 I hope this helps. please mark me brainliest :)
Answer:
Option (4)
Step-by-step explanation:
Point A is located at (0, 4) and point C is located at (-3, 5).
Let the point B is located at 
the distance from A and C.
In other words ratio of the segments AB and BC = m : n = 1 : 3
Coordinates of a point (x, y) which divides a segment having ends 
and 
= 
If the ends of the segment are (0, 4) and (-3, 5), coordinates of point B will be
= 
= 
= (-1, 7)
Option (4) will be the answer.
Answer:
The domain of the function i.e. the value of x can be any real number and the range of the function is y > 0.
Step-by-step explanation:
On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and curves up and increases in quadrant 1.
Therefore, as x tends to - ∞, the y-value tends to 0 but not equal to zero and as x tends to +∞, the y-value also tends to +∞.
Hence, the domain of the function i.e. the value of x can be any real number and the range of the function is y > 0. (Answer)
