Answer:

Option D

Y=2.6x

Step-by-step explanation:

When y=10.4 and x=4, these two can be related by the equation

10.4=4x

Making x the subject of the formula then x=10.4/4=2.6

Relating x and y then we have the equation

Y=2.6x

For example, when x is 4 then y=2.6x=2.6(4)=10.4 as given in the question. Therefore, the right option is D

Y=2.6x

EASY POINTS Find the domain of the graphed function.

Vladimir [108]

Using it's concept, it is found that the domain of the graphed function is given as follows:

D. $-4 \leq x \leq 2$

<h3>What is the domain of a function?</h3>

It is the set that contains all possible input values for the function. In a graph, it is given by the values of x.

In this graph, x assumes values between -4 and 2, inclusive due to the closed circle, hence the domain is given by:

D. $-4 \leq x \leq 2$

It is estimated that 28.5% of automobile crashes are caused by driver distraction, such as texting. If there are 16,370 automobi

frez [133]

Answer:

4665 approx

Step-by-step explanation:

Given data

Total number of crashes= 16,370 automobile crashes

Percentage caused by distraction =28.5%

Let us find the number of crashes caused by distraction

=28.5/100* 16,370

=0.285* 16,370

=4665.45

Hence the number of crashes caused by distraction is 4665 approx

13. The perimeter P (in yards) of a soccer field is represented by the formula P = 24 + 2w,

rjkz [21]

Answer:

$w = \frac{1}{2}(P - 24)$

$w = 153\ yards$

Step-by-step explanation:

Given

$P = 24 + 2w$

Require

Solving (a):

$P = 24 + 2w$

Subtract 24 from both sides

$P-24 = 24-24 + 2w$

$P-24 = 2w$

Divide both sides by 2

$\frac{1}{2}(P - 24) = \frac{2w}{2}$

$\frac{1}{2}(P - 24) = w$

$w = \frac{1}{2}(P - 24)$

Solving (b):

Substitute 330 for P un the expression in (1)

$w = \frac{1}{2}(330 - 24)$

Evaluate the bracket

$w = \frac{1}{2}(306)$

$w = 153\ yards$
