The graph doesn't represent a function

f(x) 3 because D. Yes, because each x-value has exactly one corresponding y-value.

<h3>What is a function?</h3>

It should be noted that a function simply assigns the value of each element of a particular set to the other specific element of another set.

It can be seen that in the given graph, each specific value of x from the x-axis represents a value on the y-axis. Therefore, it can be concluded that the given graph is a function because each x-value has exactly one corresponding y-value.

What is (x − 3)(x − 5) = 35

JulijaS [17]

Answer:

x=10 x=-2

Step-by-step explanation:

(x − 3)(x − 5) = 35

FOIL

x^2 -5x-3x+15 = 35

Combine like terms

x^2 -8x+15 = 35

Subtract 35 from each side

x^2 -8x+15-35 = 35-35

x^2 -8x-20 =0

Factor

What 2 numbers multiply to -20 and add to -8

-10*2 = -20

-10 +2 = -8

(x-10)(x+2) =0

Using the zero product property

x-10 =0 x+2 = 0

x=10 x=-2

During winter, Detroit is colder than Boston but warmer than Minneapolis. Which inequality correctly compares the winter tempera

Nat2105 [25]

We will take one given at a time, the common place is "Detroit", so we will take it as a reference.

1- Detroit is colder than Boston, this means that:
Temperature in Detroit < Temperature in Boston .........> I

2- Detroit is warmer that Minneapolis, this means that:
Temperature is Minneapolis < Temperature in Detroit .........> II

From I and II, we can conclude that:
Minneapolis has the lowest temperature, followed by Detroit and then Boston.

Comparing this to the choices, we will find that the correct choice is:
2. Minneapolis's temperature < Detroit's temperature < Boston's temperature

Write a vector equation of the line that passes through point P(-4,11) and is parallel to a=[-3,8]. Then write parametric equati

Assoli18 [71]

Answer:

$\vec l = (-4, 11) + t\cdot (-3,8)$ , $x = -4 - 3\cdot t$ and $y = 11 + 8\cdot t$

Step-by-step explanation:

The vector equation of the line is:

$\vec l = \vec P + t \cdot \vec A$

$\vec l = (-4, 11) + t\cdot (-3,8)$

The parametric equations of the line are:

$x = -4 - 3\cdot t$ and $y = 11 + 8\cdot t$

(8x-7)+5 when x is 2

Irina-Kira [14]

Answer:

If X=2 then the equation would be solved starting with 8x2=16 then take 16 and subtract it by 7 which would equal 9, then you take 9 and add 5 to it and that would give you the answer of 14

Step-by-step explanation:

(8x-7)+5 x=2

(8x2-7)+5

(16-7)+5

9+5

Answer 14
