Which are possible first steps in solving the equation 4x + 3 = 187

Mathematics

wariber [46]3 years ago

Answer:

Step-by-step explanation:The only one you probably can never do is B. It get's you no where. The way A is written, it is not much help to write 18 in base 2. So A and B both won't work. The common logs and the natural logs will both work

Log(4^(x + 3)) = Log(18)

(x + 3) Log(4) = log (18)

(x + 3) * 0.6021 = 1.2553

x + 3 = 1.2553/0.6021

x + 3 = 2.08496

Now all you need do is subtract 3 from both sides. The natural logs will give you the same answer.

You could take base-4 logs of both sides and it is a possible first step, but d and e are much more efficient. You have to change both sides to base 4 before you can proceed. This one is kind of iffy.  It does say possible first steps.

6. – 4y + 8x = 32 for y
MatroZZZ [7]

Answer:

The answer is: y=2x−8

Step-by-step explanation:

Step 1: Add -8x to both sides.

8x−4y+−8x=32+−8x

−4y=−8x+32

Step 2: Divide both sides by -4.

−4y−4=−8x+32−4

y=2x−8

Let the number be x.

"Two less than 3/2 of a number (x)"   means    (3/2)x - 2

"is no more than"  means     "≤"

  5 1/2

* Hopefully this helps:) Mark me the brainliest:)!!!

Y=-4x-41 that passes through (-2,7)
dalvyx [7]

Answer:

Parallel: y=-4x-1

Perpendicular: y=-4x+13/2

Step-by-step explanation:

For the equation y=-4x-41, the slope is -4. Writing a line related to this equation has two options:

  • If the line will be parallel to it then this is the slope of the new line as well. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.

(y-7)=-4(x--2)


y-7=-4x-8


y=-4x-1

  • If the line will be perpendicular to it then the slope is the negative reciprocal of the previous slope. It is 1/4.

(y-7)=1/4(x--2)


y-7=1/4x-1/2


y=-4x+13/2
