Writing equations of lines

Mathematics
1 answer:
Valentin [98]3 years ago
7 0

Step-by-step explanation:

Equation of straight line is y=mx+c

choose any two points on straight line

for me I choose:(-3,11) and (3,-1)

use these two points to find gradient,m.

m= (-1-11)/(3-(-3))

m= -2

now, y=-2x+c

choose any point on the straight line

I choose point (3,-1)

sub the point into the equation to find c

-1=-2(3)+c

c=5

equation: y=-2x+5

canada has a population that is about one tenth as large as the united states. if canada's population is about 32 million about
trapecia [35]
In this problem it states that one tenth or only 10% is Canada’s population to the United States. Hence with the steps we can identify the population of the United States.
<span><span>1.       </span>10 % = 32 million or 0.1 = 32 million</span>
<span><span>2.       </span>Then 32 million / 0.1 = 320, 000, 000 million</span>

Therefore there are 320, 000, 000 million living in the United States
Adding one zero. Why the zeroes? It is the result because of the power of 10 in a hundred percent population coming from the Canada’s population. Take note that 100% = 320, 000, 000 million of the USA while 10% of it is Canada so we divide it by 0.1 which is 32, 000, 000 (the power of ten)

The segments shown below could form a triangle?
Leni [432]

Answer:

<em>Option B; False</em>

Step-by-step explanation:

Consider a Triangle Inequality to prove that these segments could form a triangle;

| a - b | < c < a + b,\\| c - a | < b < a + c,\\| c - b | < a < b + c, Considering - a - segment AC ( 8 units ) - b - BC ( 7 units ), -  c - BC ( 15 units )\\\\| 8 - 7 | < 15 < 8 + 7,\\1 < 15 < 15, Now 15 is not < 15, it is =, thus ;\\Solution ; False

<em>These segments could not form a triangle</em>
