Answer:
x=−3 or x=5
Step-by-step explanation:
x2−2x−15=0
Step 1: Factor left side of equation.
(x+3)(x−5)=0
Step 2: Set factors equal to 0.
x+3=0 or x−5=0
x=−3 or x=5
Answer:
For number 3 your answer would be the second function.

Answer:
Value of equation = 74
Step-by-step explanation:
Given:
-26x - y
And
x = -3
y = 4
Find:
Value of equation
Computation:
-26x - y
By putting value
-26(-3) - 4
78 - 4
74
Value of equation = 74
Answer:
The distance between the two points is 8 units
Step-by-step explanation:
In the given figure
∵ The coordinates of the 2 points are (4, 5) and (4, -3)
∴ x1 = 4 and y1 = 5
∴ x2 = 4 and y2 = -3
∵ Their x-coordinates are equal
→ That means the distance between them is vertical
∴ The length of the vertical distance between two points is
the difference between the y-coordinates of the points
∵ The distance between them = Iy2 - y1I
∵ y1 = 5 and y2 = -3
∴ The distance between them = I-3 - 5I
∴ The distance between them = I-8I
→ Remember absolute value gives always positive values
∴ The distance between them = 8 units
∴ The distance between the two points is 8 units
