Using the point

we can write the equation of the line in point slope form as:

where the slope
m
=

.
That is:
y

(

)
To get point intercept form, first expand the right hand side so...
y
−
7
=
11
x

(

⋅

=

x

Then add

to both sides to get:
y

x

=

This is point intercept (

2x-y=10 y=-4x+2 substitution method
Answer:
the solution is (2, -6)
Step-by-step explanation:
Substitute the second equation into the first, replacing y in the first:
2x - (-4x+2) = 10
Simplifying, we get:
2x + 4x - 2 = 10, or:
6x = 12, which yields x = 2.
Substituting 2 for x in the second equation yields y = -4(2) + 2 = 0, or y = -6
Then the solution is (2, -6).

4x + 8y = 20 and -4x + 2y = -30
Step-by-step explanation:
Given :-
4x + 8y = 20 -4x + 2y = -30Adding the equations :-
[tex]: \implies[/tex] 10y = -10
[tex]: \implies[/tex] y = -1
Put it (i) :-
[tex]: \implies[/tex] 4x - 8 = 20

Answer:
24
Step-by-step explanation:
if A is a point between B and C, then'
BA + AC = BC

AB = 26 and BC = 50
BA = 26
Substitute
26 + AC = 50
AC = 50 - 26

The transportation department predicts that about 800,000 cars will be registered in a certain state by year 2012. Their license plates are made using and two letters followed by and three digits from 0 to 9. Will there be enough possible arrangements?
Answer:
There won't be enough arrangement
Step-by-step explanation:
Given
[tex]Letters = 2[/tex]
[tex]Digits= 3[/tex]
[tex]Cars = 800000[/tex]
Required
Determine if the possible arrangement will be enough
The 2 letters can be selected from any of the 26 alphabets without restriction.
So, the selection of letters is:
[tex]Letters = 26 * 26[/tex]
The 3 digits can be selected from any of the 10 digits without restriction.
So, the selection of digits is:
[tex]Digits = 10*10*10[/tex]
The total arrangement is:
[tex]Total = Letters * Digits[/tex]
[tex]Total = 26*26*10*10*10[/tex]
[tex]Total = 676000[/tex]
By comparison:
[tex]Total < Cars[/tex]
i.e.
[tex]676000 < 800000[/tex]
Hence, the arrangement will not be enough
