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

\bf \cfrac{x}{5}-\cfrac{x}{7}=3\impliedby &#10;\begin{array}{llll}&#10;\textit{let's multiply both sides by }\stackrel{LCD}{35}\\&#10;\textit{to do away with the denominators}&#10;\end{array}&#10;\\\\\\&#10;35\left( \cfrac{x}{5}-\cfrac{x}{7}\right)=35(3)\implies 7x-5x=105&#10;\\\\\\&#10;2x=105\implies x=\cfrac{105}{2}

I need help plzzzz!!!!!!!!:)
Mila [183]

Answer:

B: y = -2/3x - 10/3

Step-by-step explanation:

The point is at (-2,-2), therefore when you input -2 into the desired equation, it should yield -2 as our output. If we use the equation B, the equation becomes

-4/3 - 10/3 which is -6/3. After dividing it we get -2 as the output.

To find the line yourself we use the point slope formula

y - y1 = m(x - x1)

The line is parallel to the one on the graph so the slope or <em>m</em> is equal to -2/3

We input the coordinates we want for y1 and x1.

y - (-2) = -2/3 (x - (-2))

y + 2 = -2/3x - 4/3

y + 6/3 = -2/3x - 4/3

y = -2/3x - 10/3
