Answer:
Step-by-step explanation:
Population(pop) = 800,000 people
Growth rate=7℅
Pop growth in a year= ((100+7)÷100) × 800000 =856000people
Pop in 20 years = 856000×20
=17,120,000 people
Answer:
2
Step-by-step explanation:
The slope of the line is 2. The slope is rise over run, or change in y over change in x. So to find the slope count how much each value changes, in this graph y changes +2 and x changes +1. So the slope is 2/1 or just 2. One way to visually check the slope is to remember fraction slopes will make the line flatter and other whole numbers make the line steeper.
Answer:
x=8/9
Step-by-step explanation:
5x+2(x-3)=-2(x-1)
5x+2x-6=-2x+2
7x-(-2x)-6=2
7x+2x=2+6
9x=8
x=8/9
Answer:
Equation 2 is non-linear, Equation 1 is linear.
Step-by-step explanation:
A linear equation is an equation with a constant gradient and can be expressed in the form y = mx + c. Hence Equation 1 Satisfies this as it is in that form and has a constant gradient of 4. Equation 2 is not in the form y = mx + c since there is a square and hence its non-linear.
