A quadratic equation has equal roots if and only if the discriminant

is zero.
So, we have to impose

Since p is non-zero, the only possible value for p is 4/9.
Hi!
So it starts with 1.50.
1.50 +
0.50 for each mile
1.50 + 0.50x
She has $25 to spend, so the amount has to be less than or equal to $25.
1.50 + 0.50x ≤ 25
^the answer
Hope this helps! :)
7x+1 = (1/3)
2x + 2y = 28
Systems of equations.
Solve equation with single variable first.
7x+1 = (1/3) , x = (-2/21)
Substitute the value of x in second equation and solve for y.
2(-2/21) + 2y = 28, y = (296/21)
I’m assuming that isn’t the correct answer because you wrote the first equation incorrectly.
Answer:
<em>p</em><em>=</em><em>-</em><em>7</em>
Step-by-step explanation:
11+2p=p+4
2p-p=-11+4
p=-7
Product rule:


Power rule:

The exponential function is its own derivative:

Assuming the base of
is
, its derivative is

But if you mean a logarithm of arbitrary base
, we have



So we end up with
