Answer:
The Y intercept is where the line touches the axis (Black Line)
Step-by-step explanation:
So, The y intercept (-1,0)
To find slope, just divide your change in the y-values but the change in the x-values.
Answer:
Below in bold.
Step-by-step explanation:
(a) Using the Pythagoras theorem:
30^2 = 21^2 + p^2
p^2 = 30^2 - 21^2 = 459
p = √459
= 21.4 cm to nearest tenth.
(b) cos P = 21/30 = 0.70
m < P = 45.57 degrees to nearest hundredth.
Answer:
12:25
Step-by-step explanation:
Número de alunos matriculados: 2.500
Número de alunos selecionados: 1.200
A proporção que representa o número total de alunos selecionados em relação ao número de alunos matriculados é dada como:
Número de alunos selecionados: Número de alunos matriculados
= 1200: 2500
= 12 : 25
Answer:

Step-by-step explanation:
When two lines are parallel means that their slopes are equal. Therefore the line AB will have same slope to a parallel second line,
.
To obtain the slope from the line AB, we need two points, so the general equation will be:

The typical equation of a line is written as y = mx + b
The second line will pass through point (2, -1), so we can substitute:
y2 = mX2 + b
-1 =
(2) + b
then the interception is 
Now to obtain a general equation for the second parallel line will be:
y =
X + b
y =
X -
(2)-1
Finally we get:
y =
(x-2)-1
