12-y=9
3x-y=21
4y-10=2
1/4xy=6
Answer:
(0,-3) will give the maximum value
Step-by-step explanation:
To know the vertex, we have to substitute the coordinates in the options
we have this as follows
a) (1.5,0)
T = 1.5-3(0) = -1.5
b) (3.5,4)
T = 3.5 - 1)4)
= 3.5 - 4 = -0.5
c) (0,-3)
we have
T = 0-3(-3) = 0 + 9 = 9
d) (0,4)
we have this as:
T = 0 - 3(4) = -12
Answer:
39°
sum of triangle's interior angles: 180°
180°-90°-51°=39°
Answer:1375
Step-by-step explanation:
X= 15 is given
X squared is 15x15 = 225
1600 - 225= 1375
Well 3 feet=1 yard
so the conversion factor is 3ft/1yd
so 12 yards converted to feet is
12yd times 3ft/1yd
the yd will cancel and you will be left with 36 feet
each banner is 1 foot so 36/1=36
she can make 36 banners
