Answer:
In math the binary logarithm (log2 n) is the power to which the number 2 must be raised to obtain the value n. That is, for any real number x, For example, the binary logarithm of 1 is 0, the binary logarithm of 2 is 1, the binary logarithm of 4 is 2, and the binary logarithm of 32 is 5.
145−5x(0.1)+0.5=14.5
Step 1: Simplify both sides of the equation.
145−5x(0.1)+0.5=14.5
145+−0.5x+0.5=14.5
(−0.5x)+(145+0.5)=14.5(Combine Like Terms)
−0.5x+145.5=14.5
−0.5x+145.5=14.5
Step 2: Subtract 145.5 from both sides.
−0.5x+145.5−145.5=14.5−145.5
−0.5x=−131
Step 3: Divide both sides by -0.5.
−0.5x
−0.5
=
−131
−0.5
x=262
Answer:
x=262
Answer:
y = (x – 6) / -3 = [2 – x/3]
Step-by-step explanation:
y = f(x) = -3x + 6
f⁻¹(x) → x = -3y + 6 → (x – 6) / -3 → x / -3 + -6/-3 → -x / 3 + 2 → 2 – x/3
Step-by-step explanation:
Step one:
We are told that the store offers off 10% of sales, this means that the store is offsetting the price down by 10% hence a price reduction.
Moreso, <em>a coupon is a voucher entitling the holder to a discount off a particular product</em>. the coupon is 40%, hence this is equal to a discount, that is price reduction by 40%.
Step two:
<em>Say the price of an item is $100, a coupon if 40% will entitle the holder to only pay $60, that is</em>
=40/100*100
=0.4*100
=$40 off
= 100-40
=$60
<u>The total percent of reduction 10+40= 50%</u>
<u>This is equal to a discount on the sales price</u>
