Answer: 1. True 2. False
Step-by-step explanation: In question 1 they both equal 0.25 (5/20 and 7/28) but in question 2 they equal different values. 11/22=0.5 and 13/25 = 0.52.
Answer:
x>-4
Step-by-step explanation:
divide both sides by -6 without changing the sign
Answer:
<em>Exponential growth function</em>
Step-by-step explanation:
The table below represents some function between x and y:
x - 4 - 5 - 6 - 7
y - 15 - 90 - 540 - 3240
We are required to find if it's exponential growth, decay, or neither.
An exponential function is identified because each term is calculated as the previous term multiplied by a constant factor.
The values of x grow in increments of 1 and the values of x grow by a factor of 90/15 = 6, 540/90 = 6, 3240/540 = 6
Since there is a common factor and it's greater than 1, the function is exponential growth.
Answer:
<em>m∠EBC = 34° </em>
Step-by-step explanation:
m∠DBC = m∠DBE + m∠ EBC
m∠DBC - m∠DBE = m∠EBC
(12x - 3)° - (5x + 12)° = (3x + 13)°
12x - 5x - 3 - 12 = 3x + 13
4x = 28
x = 7
<em>m∠EBC </em>= (3(7) + 13)° <em>= 34° </em>
Answer:
Step-by-step explanation:
The grouping of the multiplicands has changed, but the end result will be the same.
