The following equation represents the total distance (d) that the Benson family has traveled from their home, after traveling 10

Oksanka [162]

The distance from their house the Bensons' after 412 hours will be 18, 640 miles

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

A function is an expression or rule that explains the relationship between a dependent and independent variable.

Given the function;

d= 45 t + 100

Where;

d is the total distance
t is the time taken

If t = 412 hours

Substitute into the formula

d = 45 ( 412) + 100

d = 18540 + 100

d = 18, 640 miles

Thus, the distance from their house the Bensons' after 412 hours will be 18, 640 miles

Graph this function:<br> y = 2x

77julia77 [94]

Graph is attached below.

Step-by-step explanation:

We have to graph function y = 2x,

From equation, we can see a linear relationship between the values of x and y. This equation shows that the value of y is double than the value of x.

For example,

<u>x = 0</u>

y = 2(0)

y = 0

So, point would be (0,0)

<u>x = 1</u>

y = 2(1)

y = 2

So, point would be (1,2)

<u>x = 3</u>

y = 2(3)

y = 6

So, point would be (3,6)

<u>x = -1</u>

y = 2(-1)

y = -2

So, point would be (-1,-2)

<u>x = -3</u>

y = 2(-3)

y = -6

So, point would be (-3,-6)

By matching these points, a linear graph can easily be drawn. I have also attached the graph pic below.

If s(x)=x-7 and t(x)=4x^2-x+3 which expression is equivalent to (txs)(x)?

gogolik [260]

For this case we have by definition that:

$(f * g) (x) = f (x) * g (x)$

In this case we must find $(t * s) (x),$ so:

( $(t * s) (x) = t (x) * s (x) = (4x ^ 2-x + 3) * (x-7) =$

We must apply distributive property that states that:

$(a + b) (c + d) = ac + ad + bc + bd$

So:

$(4x ^ 2-x + 3) * (x-7) = 4x ^ 3-28x ^ 2-x ^ 2 + 7x + 3x-21 = 4x ^ 3-29x ^ 2 + 10x-21$

Answer:

$4x^3-29x^2+10x-21$

A shuttle bus leaves from my office at a speed of 32 miles per

vesna_86 [32]

Answer:

2.6 hours

Step-by-step explanation:

use distance formula: d = r * t

83 = 32t

83/32 = t

2.6 = t

2.6 hours is 2 hours, 36 minutes
