Can someone help me<br> 7 + 2h = 3 + 4h

STALIN [3.7K]

h = 2

$7 + 2h = 3 + 4h$

You must isolate the variable to solve using the order of operations, or PEMDAS.

$4 = 2h$

Subtract 3 from both sides of the equation, and subtract 2h from both sides of the equation.

$\frac{4}{2} = h$

Divide both sides of the equation by 2.

$h = 2$

F(x) = 4x^2+2x+6 what is the discriminant of f? How many distinct real number zeros does f have?

Sunny_sXe [5.5K]

Answer:

The discriminant of f is 92, and it has no real zeros

Step-by-step explanation:

The discriminant of a quadratic is $b^2-4ac$ , where the quadratic is in the form $ax^2+bx+c$ . The discriminant of this one is therefore:

$2^2-4(4)(6)=4-96=-92$

Since the square root of a negative number is imaginary, this quadratic has no real number zeros. Hope this helps!

During a recent snowstorm, Boston got 2.8

ipn [44]

New York got 4.64 times more snow than Boston did.

If Boston got 2.8 feet of snow and New York City got 13 feet, the amount of feet that New York got more than Boston is:

= Amount of snow New York got / Amount of snow Boston got

= 13 / 2.8

= 4.64 more than Boston

New York therefore got about 4.64 more snow than Boston did
