Answer:
A
Step-by-step explanation:
The equation representing a proportional relationship is
y = kx ← k is the constant of proportion
The only equation in this form is
y = 24x ( k = 24 ) → A
Y - y₁ = m(x - x₁)
y - 5 = -4(x - (-2))
y - 5 = -4(x + 2)
y - 5 = -4(x) - 4(2)
y - 5 = -4x - 8
+ 5 + 5
––––––––––––
y = -4x - 3
Answer:
Step-by-step explanation:
Subtract 1 from both sides:
Divide both sides by -7:
Answer:
712
Step-by-step explanation:
400+6.5%of 4800
312+400=712
Using the formula S = ut +1/2at²
S=h= 20ft, u = 2ft/s, and a = 10m/s²
Thus; 20 =2t + 20t²
Therefore; 20t²+2t-20=0
Solving the equation quadratically for the value of t,
we get; t = 1.057 or t=-1.182
But t can not be negative,
Therefore, t= 1.1 seconds (to the nearest tenth)
