Answer:

= (x-y) (2x - y)

Step-by-step explanation:

(x–y)²–a(y–x)

= (x-y)(x-y) - a(y-x)

Factor out negative 1 from (y-x)

= (x-y)(x-y) - a(x-y)(-1)

Multiply the -1 by -a

= (x-y)(x-y) + a(x-y)

Factor out (x-y) from both terms

= (x-y) [(x-y) + a]

Remove brackets

= (x-y)(x-y+a)

Aleka and Helene both opened savings accounts that earn 2.5% interest a year. Aleka puts $2,500 into her account. Helene put $1,

Xelga [282]

Given:

Amount in Aleka and Helene accounts represented by the following function:

Aleka: $f(x) = 2500(1.025)^x$

Helene: $g(x) = 1500(1.025)^x + 200x$

To find:

The function represents the difference, $h(x) = f(x) -g(x)$ , between the value of Aleka's and Helene's total savings after x years.

Solution:

We have,

$f(x) = 2500(1.025)^x$

$g(x) = 1500(1.025)^x + 200x$

Now,

$h(x) = f(x)-g(x)$

$h(x) = 2500(1.025)^x-[1500(1.025)^x + 200x]$

$h(x) = 2500(1.025)^x-1500(1.025)^x - 200x$

$h(x) = 1000(1.025)^x - 200x$

Therefore, the correct option is C.

Help please! Geometry word problem!

mr Goodwill [35]

By applying reflection theory and constructing a geometric system of two proportional right triangles, the height of the stainless steel globe is approximately 140 ft.

<h3>How to estimate the height of the stainless steel globe</h3>

By physics we know that both the angle of incidence and the angle of reflection are same. Thus, we have a geometric system formed by two proportional right triangles:

5.6 ft / 4 ft = h / 100 ft

h = (5.6 ft × 100 ft) / 4ft

h = 140 ft

72 is equal to 80% of a number n. Write and solve and equation to find n. Write the percent as a decimal.

valentina_108 [34]

Well I'm not sure what the answer would be since I'm not that smart but I did get the answer of 90, I did this by dividing 72 by 80 which equals .9 and I multiplied that by 100 and got 90.
