Answer:
128 = 80 + 64 t - 16 t^2
8 = 5 + 4 t - t^2
3 = t (4 - t)
Inspection shows the equation is solved if
t = 1 and t = 3
Plug into original equation to check
Answer:
20
Step-by-step explanation:
You basically just plug in the numbers given for the variables and solve.
2(7)+3(2) = 14+6= 20
Answer:
b.) -4
Step-by-step explanation:
rise/run so its 8/2
Answer:
8/3
Step-by-step explanation:
4x+1/3=11=33/3
4x=32/3
x=8/3
<span>identity is subtraction property of equality
equation is x + 8 = 6
</span><span>
Substitution Property of Equality; x + 8 = 6
</span><span>
Take the equation x + 8 = 6.
subtract 8 from both sides using the subtraction property of equality
x + 8 - 8 = 6 - 8
simplify
x + 0 = -2
x = -2</span><span>
