Answer:

D. (5, 0) and (4, 0)

Step-by-step explanation:

we know that

The x-intercepts are the values of x when the value of the function is equal to zero

Looking at the graph

The x-intercepts are the points (4,0) and (5,0)

Answer:

The value of f(1) is smaller than the value of f(3)

Step-by-step explanation:

<u><em>The correct question is</em></u>

Given the function f(x) = 2x^2 + 3x + 10, find f(1) and f(3). Choose the statement that is true concerning these two values.

The value of f(1) is the same as the value of f(3).

The value of f(1) cannot be compared to the value of f(3).

The value of f(1) is larger than the value of f(3).

The value of f(1) is smaller than the value of f(3)

we have

$f(x)=2x^{2}+3x+10$

step 1

Find out the value of f(1)

substitute the value of x=1 in the function f(x)

For x=1

$f(1)=2(1)^{2}+3(1)+10$

$f(1)=15$

step 2

Find out the value of f(3)

substitute the value of x=3 in the function f(x)

For x=3

$f(3)=2(3)^{2}+3(3)+10$

$f(3)=37$

step 3

Compare the values

37> 15

f(3) > f(1)

f(1) < f(3)

therefore

The value of f(1) is smaller than the value of f(3)

What is the solution to this system of equations?

vovangra [49]

3x + 2y=-10 equation 1

y=-x -4 equation 2

use the substitution method of elimination to get the answer to the question.

*using substitution

substitute equation 2 in one and we get

3x +2(-x-4)=-10

3x- 2x-8=-10

x=-2 and y=-2

The value of x varies directly with y, and when x= 1/3,y = 12. Write an equation to represent the direct variation.

shtirl [24]

Answer:

Equation: $y = 36x$

Step-by-step explanation:

The equation that represents a direct variation between variable x and variable y is given as $y = kx$ . Where, k is the constant of proportionality.

Find the value of k given that x = ⅓ and y = 12.

Plug the values into the equation.

$y = kx$

$12 = k\frac{1}{3}$

Multiply both sides by 3

$12*3 = k*1$

$36 = k$

Substitute the value of k into $y = kx$

$y = 36x$

Equation: $y = 36x$
