Option 1
because the x line is vertical and that’s the only one that crosses at 5
Answer:
D
Step-by-step explanation:
x(-3x+4)=x*(-3)+x*4=-3x^2+4x
Answer:
x = 2/3
DF = 10
scale factor of ΔDEF to ΔXYX is 1:3
Step-by-step explanation:
DF corresponds to XZ and DE corresponds to XY so we can set up a proportion:
6x+6/30 = 8/24
simplify 8/24 to be 1/3
6x+6/30 = 1/3
cross-multiply:
3(6x+6) = 30
18x + 18 = 30
18x = 12
x = 12/18 or 2/3
Answer:
$119.795 (aprox)
Step-by-step explanation:
Proportions:
$35 ⇔ 220 minutes
$C ⇔ 753 minutes
C = 753*35/220
C = $119.795 aprox.
