Propportinal
means that the points are inproportion
ratios
1:3=2:6=3:7
1/3=2/6=3/7
1/3=1/3=3/7
false
therefor it is not poropoortional
another way is to graph the points and see if a straight line can go though all of them
it can go thoruhg the first 3 but not eh 4th pont (3,7)
not proportional
Answer:
X = -5
Step-by-step explanation:
Subtract one from both sides
- 3 = 3x / 5
multiply by 5 to remove fraction
-15 = 3x
divide by 3
x = -5
Let the digits be x and y
Given that- xy= 18 and x+y=9
SO y= 18/x
And x+(18/x)=9
x^2 -9x+18=0
(x-6)(x-3)=0
So x=6,3
(x-3)(x+7) —> multiply them together I do it by FOIL which stands for Firsts Inners Outers Lasts
x’(squared)+7x-3x-21 —> simplify
x(squared)+4x-21
V = sqrt (64h)
V = sqrt (64 * 23)
V = sqrt 1472
V = 38.366 rounds to 38.37 ft <==
