Answer:

x = 3/5

Step-by-step explanation:

After substituting each option into the equation, we find that the only option that makes the equation true is x=3/5, since 4/5 - 3/5 = 1/5.

The function f(x) = 2x2 + 3x + 5, when evaluated, gives a value of 19. What is the function’s input value?
iren2701 [21]
F(x)......ur output = 19

19 = 2x^2 + 3x + 5
2x^2 + 3x + 5 - 19 = 0
2x^2 + 3x - 14 = 0
(2x + 7)(x - 2) = 0

2x + 7 = 0
2x = -7
x = -7/2

x - 2 = 0
x = 2

I believe there is 2 possible answers......x (ur input value) = -7/2 or 2

Is 3x^2 + 2x + 10 = 0 written in standard form?
Nataly_w [17]

Answer:

in the US, yes

in some other English-speaking countries, no

Step-by-step explanation:

"Standard form" depends on where you live. In the UK, the "standard form" of a quadratic equation is what is called "vertex form" in the US. That form is ...

3(x +1/3)^2 +29/3 = 0

In the US, the equation you show is in standard form.

The sum of three consecutive even numbers is one hundred sixty - two.
Alenkasestr [34]

Answer:

 52

Step-by-step explanation:

Let x represent the smallest of the three numbers. Then the other two are (x+2) and (x+4). Their sum is ...

  x + (x+2) +(x+4) = 162

  3x = 156 . . . . . . . . . . . .subtract 6

  x = 156/3 = 52

The smallest of the three numbers is 52.

___

I like to work problems like this by considering the average number. Here, the average of the three numbers is 162/3 = 54, the middle number of the three. Then the smallest of the three consecutive even numbers is 2 less, or 52.
