A pet shelter maintains a ratio of 5 cats to 8 dogs. If there are 117 total animals in the shelter, how many are dogs? Set up and solve a proportion.
Answers
Given:3x-4=8 prove x=4
Answers
Hi!
Okay, so to prove that x = 4, all you have to do is insert 4 into the equation by replacing x with 4.
3x-4=8
3(4)-4=8
Now solve:
12-4=8
8=8
This is true, so x does equal 4.
does the equation 4(2x+3)=16x+12-8x have one solution, infinitely many solutions, no solution, or two solutions.
Answers
Answer:
Infinite number of solutions
Step-by-step explanation:
Use distributive property to eliminate the parenthesis on the left:
8 x + 12 = 16 x + 12 - 8 x
combine like terms on the right:
8x+ 12 = 8 x + 12
subtract 12 from both sides
8 x = 8 x (notice both sides are identical)
subtract 8 x from both sides
0 = 0
This is a true statement that takes place for whatever x-value we use in the original equation. Therefore, the equation has infinite number of solutions (any real number "x")

The weights, in pounds, of the cats in an animal adoption center are normally distributed. If a random sample of cats is taken and the confidence interval is (7.9,12.7), what is the margin of error?
Give a numerical response for your answer. For example, if you found that the margin of error was 2, you would enter 2.
Answers
Answer:
2.4
Step-by-step explanation:
Given that :
The confidence interval = ( 7.9 , 12.7 )
The Margin of error M.O.E = Interval width/2
where;
The interval width = UCL - LCL
The interval width = 12.7 - 7.9
The interval width = 4.8
∴
The Margin of error M.O.E = 4.8/2
The Margin of error M.O.E = 2.4

Answer:
23, 15, 7, 3
Step-by-step explanation:
Answer:
x = 1 y =23
x = 3 y = 15
x = 5 y = 7
x = 6 y = 3
Step-by-step explanation:
what the x is saying when it says it equals 1, 3, 5, and 6 its basically saying anytime you see an x in the problem hence the y =27 - 4x you replace the x with the number that x equals for example if x = 3 I plug three in every time I see an x in the equation like the equation y = 27 - 4x so it would be y = 27 - 4(3) (parentheses meaning 4 times 3) so it would be now y = 27 - 12 and that would be y = 15 hope this helps :)

Find the equation of the tangent line. y=(x^2+x-2)^2 at (-1,4)
Answers
Compute the derivative of y = (x² + x - 2)² using the chain rule:
dy/dx = 2 (x² + x - 2) d/dx [x² + x - 2]
dy/dx = 2 (x² + x - 2) (2x + 1)
Evaluate the derivative at x = -1 :
dy/dx (-1) = 2 ((-1)² + (-1) - 2) (2 (-1) + 1) = 4
This is the slope of the tangent line to the function at (-1, 4).
Use the point-slope formula to get the equation for the tangent line:
y - 4 = 4 (x - (-1)) → y = 4x + 8
