Just go ahead and subtract 3/4x and bring it to the other side so it should look like this -2y=5-3/4x then go ahead and divide with negative two
<span>If this statement is a True or False question.
Then, TRUE. A "b" value of less than 1 produces a graph with exponential decay.
We consider this formula: y = a*b^x or f(x) =a*b^x
a is the initial value, b is the rate, x is the exponent.
If b has a value of less than 1, as the exponent increases the resulting value of y decreases.
f(x) = 20(0.90)^x
f(1) = 200(0.90)</span>¹ = 180
f(2) = 200(0.90)² = 162
f(3) = 200(0.90)³ = 145.80
f(4) = 200(0.90)⁴ = 131.22
f(5) = 200(0.90)⁵ = 118.10
Exponential decay is the decrease in a quantity. As you can see in the given example the value of f(x) decreases as the value of x increases because the value of b is less than 1.
Answer:
Step-by-step explanation:
Let the speed of faster plane be x
therefore ,
speed of slower plane = x - 20
As the time taken is same ,
therefore ,
faster plane travels at a speed of 190 miles/hr
while..
the slower plane travels at a speed = ( 190-20 ) miles/hr
=> 170 miles/hr
hope helpful~
