Total units of ratio = 1+4+5 = 10
Value of 1 unit = 180/10 = 18
It would be 1(18), 4(18), 5(18) = 18, 72 & 90
-4 or
Rise 4 and run 1 to the left (that's what makes it negative)
Answer:
C
Step-by-step explanation:
y=-3x+5
Let's try A: 14=-3*3+5=-9+5=-4 (NOT TRUE)
Let's try B: 17=-3*4+5=-12+5=-7 (ALSO NOT TRUE)
Let's try C: 17=-3*(-4)+5=12+5=17 (TRUE)
Let's try D: 23=-3*6+5=-18+5=-13 (NOT TRUE)
Hope this helps!
Answer: 20.48
Step-by-step explanation:
use the pythagorean theorem for the diagnal sides
3^2+3^2=c^2
9+9=c^2
18=c^2
this gives you 4.24
now add 6+6+4.24+4.24 to get 20.48
Answer:
x=4, y=-2
Step-by-step explanation:
-5x+8y=-36
5x+7y=6
eqn 1+ eqn 2 gives
15y=-30
divide both sides by 15
y=-2, put in eqn 2
5x+7(-2)=6
5x=20 divide both sides by 5
x=4
