its 60
4 x 12 = 48
3 x 4 = 12
48 + 12 = 60
yeeeet
the answer is a.
step-by-step explanation:
in three games of golf, alex shot two under par four times.
let y equal to
the total fare and x is the mile of taxi ride. so the equation is
y = 0.55x + 1.75
since susie has
$10 to spend for a taxi cab, so he can have
10 = 0.55x +
1.75
x = 15 miles of
taxi ride
so the system of
inequality is
10 < 0.55x +
x > 2
"standard form:
3x2 + 14x β 10 = 0
solutions based on quadratic formula:
x1 = β14 β β 142 β 4Γ3Γ(β10) / 2Γ3 = β14 β 2 Γ β 79 / 6 β β5.296
x2 = β14 + β 142 β 4Γ3Γ(β10) / 2Γ3 = β14 + 2 Γ β 79 / 6 β 0.629
