Explain why you can use subtraction to solve a division problem.

Subtraction is finding the difference between two numbers whereas division is putting numbers into equal pairs or undoing multiplication ( if that helps ) So... If they say divide 6 by 2 they mean put six into equal pairs of 2 which would equal 3 E.g.:- ( there are 3 pairs of six cars in twos ) You can't use subtraction because that will just find the number difference of 6 and 2 which is 4 Hope that wasn't complicated

the length of a rectangle is 13 centimeters less than its width. What are the dimensions of the rectangle if it’s area is 114 sq

Novosadov [1.4K]

Answer:

w = 19

L = 6

Step-by-step explanation:

L = w - 13

a = lw

114 = w(w - 13)

114 = w² - 13w

w² - 13w - 114

(w - 9) (w + 6)

w ≠ -6 (a length cannot be negative)

w = 19

L = 19 - 13

L = 6

I(t) = 27, 992 * (1.017) ^ t covert to log

klemol [59]

Answer:

By 2034 Texas per capita income would reach at least $50,000

Step-by-step explanation:

Given;

$I(t) = 27,992(1.017)^t$

Converting the given function to log;

$I(t) = 27,992(1.017)^t \\\\\frac{I(t)}{27,992} = (1.017)^t\\\\Log_{1.017} ( \frac{I(t)}{27,992} )= t \\\\(Based \ on \ log \ rule; if \ a = b^y , in \ log \ it \ will \ be \ written \ as, Log_b \ a = y)$

(B) When I(t) = $50,000, the time "t" will become;

$Log_{1.017} ( \frac{I(t)}{27,992} )= t\\\\Log_{1.017} ( \frac{50,000}{27,992} ) = t\\\\Log_{1.017} (1.7862) = t\\\\34.4 \ years = t$

Thus, by 2034 Texas per capita income would reach at least $50,000

Find the value of b that makes <img src="https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20%2Bbx%2B%5Cfrac%7B9%7D%7B4%7D%20" id="TexFormu

Perfect square trinomial is like

(x+4)^2=x^2+8x+16
they are represented as such
ax^2+bx+c
so to solve for b you do
(√c) times 2=b so

c=9/4
square root=3/2 because 3/2 times 3/2=9/4
(√(9/4)) times 2=(3/2) times 2=6/2=3
so b=3

x^2+3x+(9/4)
if factored, it gives
(x+(3/2))(x+(3/2)) or
(x-(3/2))(x-(3/2))

if this equation is equal to 0 then x=-3/2 or 3/2

the value is 3
