The fucntion f(x)=2x^2+3x+5 when evaluated, gives a value of 19. What is the functions input value?
BlackZzzverrR [31]

Answer:

x1= 14/4 and X2 = -2

Step-by-step explanation:

To find the values of "X" for which when the function is evaluated gives 19 we need to equal the function to 19, as follows:

2x^2+3x+5 = 19

2x^2+3x+5-19=0

2x^2+3x-14=0

Then, solving for "x" we need to use the quadratic formula (Attached), where a, b, and c, are the following:

a: 2 b: 3 c: 14

Using the quadratic formula, we get:

x1= 14/4 and X2 = -2

HELPP!!
Mamont248 [21]

Answer:

Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6.

What is Y equals negative 2X plus 6 in standard form
Sergio039 [100]

Answer:

2x + y - 6 = 0

OR 2x + y = 6

Step-by-step explanation:

First write the equation given in the problem:

y = -2x + 6        This is in slope-intercept form (y = mx + b).

Standard form is written Ax + By + C = 0. When C is a negative number, you might also see it as Ax + By = -C.

The main difference between the two forms in that slope-intercept form isolates the 'y' whereas standard form equates to 0. Don't confuse the 'b' in standard from with the 'B' in slope-intercept form.

To convert from slope-intercept form to standard form, <u>move everything over to the side with 'y'</u>. When you move something, you do its reverse operation to the whole equation. (The reverse of addition is subtraction, the reverse of multiplication is division.)

y = -2x + 6         Do the reverse operations for -2x and +6

y + 2x - 6 = -2x + 2x + 6 - 6      Add 2x and subtract 6 on both sides

y + 2x - 6 = 0            Right side cancels out to be '0'.

2x + y - 6 = 0       Rewrite with the 'x' in front of the 'y'

Here you can see the new equation and what each variable in Ax + By + C = 0 is.

A = 2

B = 1              When a number is not written with the variable, it is 1.

C = -6

Some teachers ask it to be rewritten as Ax + By = -C when 'C' is a negative number.

2x + y = 6
