Answer:
We simplify the equation to the form, which is simple to understand
5x+25=10
We move all terms containing x to the left and all other terms to the right.
+5x=+10-25
We simplify left and right side of the equation.
+5x=-15
or this is another way
Simplifying
5x = 25 + -10
Combine like terms: 25 + -10 = 15
5x = 15
Solving
5x = 15
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '5'.
x = 3
Simplifying
x = 3
We divide both sides of the equation by 5 to get x.
x=-3

Answer:
The length is 2.5 units
Step-by-step explanation:
Before we find the value of the length of the side, we need the measure of the coordinates after dilation
B’ = 1/2 B = 1/2(3,2) = (1.5, 1)
C’ = 1/2 C = 1/2( 0,-2) = (0,-1)
The measure of the length is the distance between the two points
Mathematically, that would be;
D = √(x2-x1)^2 + (y2-y1)^2
D = √(0-1.5)^2 + (-1-1)^2
D = √(2.25 + 4)
D = √6.25
D = 2.5 units
Answer:
The second option (choice b)
Step-by-step explanation:
At -1 is the line starts going up so its increasing. 2 shows that the line is starting to decrease so it would be between -1 and 1 where the line is increasing on the graph.
