distance : 15 units
coordinates : (7,0) and (-8, 45)
slope:
equation:
the y-intercept of this function:
distance between both y-intercept :
21499 +12*x=22.75*x
21499=22.75x-12x
21499=10.75x
x=21499/10.75≈1999.9≈2000 books
Answer:
16
Step-by-step explanation:
Let the number = x
x + x/2 - 20 = 1/4 x
3/2 x - 20 = 1/4x Multiply by 4
3*2 x - 80 = x
6x - 80 = x
6x - x - 80 = 0
5x - 80 = 0
5x = 80
x = 16
Check
16 + 8 - 20 = 1/4 * 16
24 - 20 = 4
4 = 4
Answer:
linear equation for 2y+10x=60 is y=-5x+30 .. the other one is invalid
Step-by-step explanation:
Subtract 7 both sides
52-7=45
45 divide 5x = 9
X greater than 9 or equal 9
