A)your equation for t-mobile would be
y=20x+100
Topar equation
y=30x
B) you’d set the two equation equal to each other
20x+100=30x
giving you the answer x=10
C) when x>13
D) when x<14
i’m a bit iffy on the last two but that’s the conclusion i came to
Answer:
i) k = 36.8
ii)y = 36.8/square root of x
iii)y = 1.4
Step-by-step explanation:
If y is inversely proportional to square root of x;
then the two variables are related by,
y = k/ square root of x
i)Value of k when...x = 8 and y = 13,
substitute into the equation above..so as to find the value of k
13 = k/square root of 8
;k = 13 × square root of 8
;k = 36.8
ii)Then substitute the value of k with...36.8
y = 36.8/square root of x
iii)If x = 27...then y =;
y = 36.8/27
y = 1.4
Answer:
Step-by-step explanation:
The Distributive Property states: a(b+c) = ab+ac.
5(6+12) is the expression.
5•6+5•12 is the product of the Distributive Property.
30+60 is the product of multiplication.
Therefore, 30+60 is the correct answer.
• We just distributed the 5 to the 6 and 12 because the entire expression of 6+12 is being multiplied by the 5, hence there are parentheses.
