Answer:
<u>Proportional relationship:</u>
<u>Use a pair of points (0.14, 0.7) to find the value of k:</u>
- 0.7 = 0.14k
- k = 0.7/0.14
- k = 5
<u>The function is:</u>
<u>Fill in the table:</u>
- x = 3.1 ⇒ y = 5*3.1 = 15.5
- x = 2.5 ⇒ y = 5*2.5 = 12.5
- x = 1.2 ⇒ y = 5*1.2 = 6
- x = 0.9 ⇒ y = 5*0.9 = 4.5
- y = 0.3 ⇒ x = 0.3/5 = 0.06
- y = 0.1 ⇒ x = 0.1/5 = 0.02
Answer:
x = 5/7
Step-by-step explanation:
Here, we want to get the value of x
Firstly, according to indices;
(a^m)^n = a^(m * n) = a^mn
Also;
a^m * a*n = a^(m + n)
a^0 = 1 (any number raised to zero as its power is 1)
And lastly;
a^m divided by a^n = a^(m-n)
So using these we can have;
7^4x = 7^( 2 + 3)/7^3x
7^4x = 7^5/7^3x
7^4x = 7^(5-3x)
Since we have the same bases, we have to equate the powers
4x = 5-3x
4x + 3x = 5
7x = 5
x = 5/7
