Answer:
y + 9 = - 10(x - 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (1, - 9) and (x₂, y₂ ) = (- 10, 101)
m = 
= 
= - 10
Using (a, b) = (1, - 9), then
y - (- 9) = - 10(x - 1), that is
y + 9 = - 10(x - 1)
Answer: Each blueberry pie costs $14 and each blackberry pie costs $18.
Step-by-step explanation:
If X is the price of a blueberry pie and Y is the price of a blackberry pie we have that:
3*X + 12*Y = $258
4*X + 3*Y = $110
We have a system of equations, to solve it first we can isolate one of the variables in one of the equations, let's isolate X in the first equation.
3*X = $258 - 12*Y
X = $258/3 - (12*Y)/3 = 86 - 4*Y
now we can replace it in the second equation and get:
4*(86 - 4*Y) + 3*Y = 110
344 - 16Y + 3Y = 110
344 - 13Y = 110
13Y = 344 - 110 = 234
Y = 234/13 = 18
So each blackberry pie costs $18.
And we can replace it in the equation for X and get the value of X.
X = 86 - 4*Y = 86 - 4*18 = 14
So the price of a blueberry pie is $14.
You can't write it as a fraction.

Answer:
There is no solution for x.
Step-by-step explanation:
We are given that 
and we have to solve for x.
Let us assume that 
then 
........ (1)
Now, we know that for any value of x the value of cos x lies between 1 to - 1.
Hence, 
for all x.
⇒ 
Now, for , the value of 
can never be equal to 1.
Hence, there is no solution for x. (Answer)
