3x+8=15 find try the value of x

bazaltina [42]

3x+8=15

move +8 to the other side

sign changes from +8 to -8

3x+8-8= 15-8

3x= 15-8

3x= 7

divide both sides by 3 to get x by itself

3x/3= 7/3

answer:

7/3 or 2 1/3

Forensic scientists use the following law to determine the time of death of accident or murder victims. If T denotes the tempera

Naddik [55]

Answer: He was killed 24.83 hours before the body was found.

Step-by-step explanation:

Since we have given that

$T=T_0+(T_1-T_0)(0.97)^t$

Here, T is the temperature of a body t hr after death, T = 82°F

T₀ is the air temperature , T₀ = 67°F

T₁ is the body temperature at the time of death = T₁ = 98.6°F

So, we will substitute all the values in the above equation.

$82=67+(98.6-67)(0.97)^t\\\\82-67=31.6(0.97)^t\\\\\dfrac{15}{31.6}=(0.97)^t\\\\0.474683544=(0.97)^t\\\\\text{Taking ln on both sides}\\\\\ln(0.474683544)=t\ln(0.97)\\\\-0.745=t\times -0.030\\\\t=\dfrac{0.745}{0.030}\\\\t=24.83\ hours$

Hence, he was killed 24.83 hours before the body was found.

19. Suppose Misty purchased the 10-Day Ticket Package that

Luda [366]

Answer:

Part a) The table in the attached figure (see the explanation)

Part b) see the explanation

Step-by-step explanation:

Let

y ----> the total cost of Lift Tickets

x ----> the number of days

we know that

The linear equation in slope intercept form is given by

$y=mx+b$

where

m is the slope or unit rate of the linear equation

b is the initial value or y-intercept pf the linear equation

In this problem we have

The slope is equal to

$m=\$20\ per\ day$

The y-intercept is equal to

$b=\$80$

substitute

$y=20x+80$

<u><em>Complete the table</em></u>

Find the value of y for each value of x

For x=0 day

$y=20(0)+80=\$80$

For x=1 day

$y=20(1)+80=\$100$

For x=2 days

$y=20(2)+80=\$120$

For x=3 days

$y=20(3)+80=\$140$

For x=4 days

$y=20(4)+80=\$160$

For x=5 days

$y=20(5)+80=\$180$

For x=6 days

$y=20(6)+80=\$200$

Part b) Explain how you know the data in the table above is linear

The data in the table is linear, because satisfy the equation of the linear equation

$y=20x+80$

where

x is the variable independent or input value (the number of days)

y is the variable dependent or output value (the total cost of Lift Tickets)
