Answer:
(-2, -4.5)
Step-by-step explanation:
We can solve this equation with substitution.
x=2y+7
3x-2y=3
We can "substitute" 2y+7 for x into the second equation:
3(2y+7)-2y=3
Distribute the 3
6y+21-2y=3
Add like terms
4y+21=3
Subtract 21 from both sides
4y=-18
Divide both sides by 4 to isolate y
y=-4.5
Plug -4.5 back in for y:
x=2(-4.5)+7
x=-9+7
x=-2
(x,y)=(-2,-4.5)
Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The number of members is n = 15
Generally the number of ways of selecting two member from the fifteen members is mathematically represented as

Here C stands for combination hence we will be making use of the combination functionality in our calculator

=> 
=> 
Gnerally the number of outcome that matches the outcome required by the committee(Which is reselecting the member who where the chairman and vice chairman of the board ) is m = 1
Generally the probability of randomly selecting the two members who currently hold the positions of chairman and vice chairman and assigning them to their current positions is mathematically represented as

=> 
=>
=>
Is there another part to this question? What should we answer?
Answer:
(Slope intercept form)
(Slope point form)
Step-by-step explanation:
The slope of the line can be calculated as following:

The the equation of the line in slope point form is:

Where (
,
) is a point of the line.
Then you must susbtitute the point given and the slope and you obtain:

The intercept form is:

Where b is the y-intercept.
Solve for y from the equation of the line in slope point form obtained above, then:
