a 75 inch boars is cut into 2 pieces one piece is 4 times the length of the other find the lengths of the 2 pieces the short piece is _inches long

Answers

Answer 1

Answer: Length of the long piece = 4 times the length of the short piece
Length of the short piece = 1 times the length of the short piece.
Total length of both pieces = (4 + 1) = 5 times the length of the short piece.

5 times the length of the short piece = 75 inches

The length of the short piece =75 / 5 = 15 inches

Length of the long piece = 4 times the length of the short piece = 60 inches

Check: 15 + 60 = 75 inches
yay

Answer 2

Answer: The shorter piece is 15 inches, and the longer piece is 60 inches.
This would be a system of equations problem. If x is the shorter piece and y is the longer piece, then your two equations would be:
x + y = 75
y = 4x
Since the second equation tells you what y is, you can substitute the y in the first equation with 4x to get the equation x + 4x = 75. x + 4x is 5x, so you'll have 5x = 75. To get x by itself, divide off the 5 on both sides. 75 ÷ 5 = 15, so x = 15. The shorter piece would be 15 inches long.
Now that you know x, go to the second equation and plug it in: y = 4·15. 4·15 is 60, so that makes the longer piece 60 inches long.
Sorry if this was confusing; I'm really bad at giving written directions :/

How do i solve log6(25)-log6(5)

Answers

There's nothing there to solve. But you can simplify the expression.

-- The difference of two logs is the log of the quotient.

log₆(25) - log₆(5)

= log₆(25/5) = log₆(5) .

That may be all you can do with it.
If they want you to go ahead and actually find the value of log₆(5) ...
I don't remember how to do that. If it was log₁₀(5) or ln(5) ,
those would be easy, because they're right on your calculator.
But the log to the base of (anything else other than 10 or 'e') takes
an additional step, which I don't remember.

The equation of a line is y = -3x - 2. What are the slope and the y-intercept of the line? slope = -3 and y-intercept = 2 slope = 3 and y-intercept = -2 slope = 3 and y-intercept = 2 slope = -3 and y-intercept = -2

Answers

Answer:

slope -3 and y-intercept -2

Step-by-step explanation:

The slope:

the general linear function is y=mx+n where m is the slope

so slope = -3

y intercept is when x=0

y=-3*0-2

y=-2
