What is the difference? StartFraction x 5 Over x 2 EndFraction minus StartFraction x 1 Over x squared 2 x EndFraction StartFract
Troyanec [42]

The difference of the given fraction is expressed as \frac{x^2+4x-1}{x(x+2)}

Given the expression:

  • \frac{x+5}{x+2}-\frac{x+1}{x^2+2x} \\

Take the LCM of the fraction to have:

=\frac{x+5}{x+2}-\frac{x+1}{x(x+2)} \\=\frac{x(x+5)-(x+1)}{x(x+2)} \\=\frac{x^2+5x-x-1}{x(x+2)}\\=\frac{x^2+4x-1}{x(x+2)}

Hence the difference of the given fraction is expressed as \frac{x^2+4x-1}{x(x+2)}

What is the measure of n?
horsena [70]

The value of n is 32 if the total; base length is 12(8+4) and n is the length of the perpendicular.

<h3>What is a right-angle triangle?</h3>

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

We can use the altitude rule:

8/n = n/4

n² = 32

n = √32

Thus, the value of n is 32 if the total; base length is 12(8+4) and n is the length of the perpendicular.

Write the equation of the linear relationship in slope-intercept form, using decimals as needed.
Vedmedyk [2.9K]

Answer:

y = -0.3x + 103

Step-by-step explanation:

✔️Find the slope (b):

Slope = ∆y/∆x

Using, (25, 95.5) and (35, 92.5),

Slope (m) = (92.5 - 95.5)/(35 - 25) = -3/10 = -0.3

✔️Find the y-intercept (b):

Substitute (x, y) = (25, 95.5) and m = -0.3 into y = mx + b

95.5 = -0.3(25) + b

95.5 = -7.5 + b

95.5 + 7.5 = b

103 = b

b = 103

✔️To write the equation, substitute m = -0.3 and b = 103 into y = mx + b

Thus:

y = -0.3x + 103
