Answer:
C. 5/2
Step-by-step explanation:
Two points that the graph passes through are (-5, -4) and (-3, 1). This tells us that the graph goes up 5 units at the same rate that it goes right 2 units. Since the slope of a graph is simply the movement of the y values over the movement of the x values, the slope of this graph is 5/2, which is option C.
Answer: If you need to find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem if you know the length of the other two sides. Square the length of the 2 sides, called a and b, then add them together. Take the square root of the result to get the hypotenuse
Answer:
x=-20
Step-by-step explanation:
1. Expand 3(x+8) : 3x+24
2.Expand -3(7-1/4x): -21*3/4x
3. 3x+24= -21*3/4x
4.<em>Subtract 24 from both sides</em>
3x+24-24= -21*3/4x-24
5.3x= 3/4x-45
6.<em>Subtract 3/4 from both sides</em>
3x-3/4= 3/4x-45-3/4
7.9/4x=-45
8<em>.Multiply both sides by 4</em>
9/4x*4=-45*4
9.9x=-180
10.<em>Divide both sides by 9</em>
9x/9=-180/9
11. x=-20
