The input value that gives an output of 19 is not listed in the answer choices. None of the options are correct.
What are the factors?A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.
Here,
We can start by setting up the equation:
2x² + 3x + 5 = 19
Subtracting 19 from both sides:
2x² + 3x - 14 = 0
(2x - 7)(x + 2) = 0
Using the zero product property, we can solve for x:
2x - 7 = 0 or x + 2 = 0
2x = 7 or x = -2
x = 7/2 or x = -2
Therefore, the input value could be either 7/2 or -2.
The answer choices do not include 7/2, but we can check both input values to see which one gives an output of 19:
f(7/2) = 2(7/2)^²+ 3(7/2) + 5 = 19.25
f(-2) = 2(-2)² + 3(-2) + 5 = 3
Thus, the input value that gives an output of 19 is not listed in the answer choices.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as D
Now , the value of D is
Substituting the values in the equation , we get
Let the total distance ran by Johnny be D = ran 2 miles north, 6 miles west, 3 miles north, 10 miles south, 8 miles east, and then 2 miles
So , D = 2 + 6 + 3 + 10 + 8 + 2
On simplifying the equation , we get
D = 31 miles
Hence , the distance is D = 31 miles

Suppose y is directly proportional to x. If y= 24 when x=2, what is the value of x when y= 144?
Answer:
12
Step-by-step explanation:
Because y=24 and x=2 you do the following:
144/24=6
Then, 6x2=12 because it is proportional
Or you could do 24/2=12 and 144/12=12

What value of x makes the equation below true? −2x=−36 A x=−34 B x=−38 C x=−18 D x=18
Answer:
D x = 18
Step-by-step explanation:
Given equation:
−2x = −36
Divide both sides by -2 to find x
−2x / -2 = −36 / -2
x = −36 / -2
x = 18
x = 18 makes the equation −2x = −36 true
