which of the value of x satisfies the equation below -2x-7=12

A: x= -9.5

B: x= -9

C: x=9

d:x=9.5

Answers

Answer 1
Answer is A.
You start by adding the 7 to the opposite side. Giving you 19. You divide both sides by -2 which gives you x on one side and -9.5 on the other.

-2x-7=12
-2x=12(+7)
-2x=19
x=19/-2
x=-9.5

[tex]y = 40000(1.02)^8[/tex]

Step-by-step explanation:

Given

[tex]a = 40000[/tex] -- Initial population

[tex]r = 2\%[/tex] --- Rate

Required

Determine the population in 8 years

The question shows an exponential distribution and the final population will be calculated using:

[tex]y = a(1 + r)^x[/tex]

Where x is the number of years.

So, we have:

[tex]y = 40000(1 + 2\%)^8[/tex]

Convert % to decimal

[tex]y = 40000(1 + 0.02)^8[/tex]

[tex]y = 40000(1.02)^8[/tex]

A gift card stores data using a black, magnetic stripe on the back of the card. Find the width w of the stripe.

Answers

The width of w is 0.90 cm.

Find the length of the sides:

The first step to solve this problem is to find how long is each side.  About this, we know one side is 8 1/2 cm or 8.5 but the other side is not exactly given (4cm + w + 2/3 w). To determine the length of this size, use the area formula:

A = side a x side bSide b = A / side aSide b = 46.75 / 8.5Side b 5.5

Find the length of w:

The total length of the side - known side

5.5 - 4 = 1.5

This means w + 2/3 w (0.66 w) is equal to 1.5

Find w:

w + 2/3 w = 1.5w + 0.66w = 1.51.66 w = 1.5w = 1.5/ 1.66w =  0.90 cm
