If we have the equation of a line: y=ax+b
How to find a if with only the x<span>-intercepts (called m)</span> and y-intercepts (called n)
+ First we have y=0 and x=m or 0=a*m+b or b= -a*m
+ Then we have x=0, y=n or n=a*0+b or b=n
And if m≠0 we have a= -n/m
and if m=0 this line has no slope
Answer:
the number of cakes sell is 5
Step-by-step explanation:
The computation of the number of cakes sold is shown below;
Let us assume
The cake be C
And, the pie cost be P
Given that
There is two types of baked goods sold
The cost of the cake is $4
And, the cost of the pie cost is $64
Now the store sold 9 baked goods for a total of $44
So, the equation would be
C + P = 9
P = 9 - C ...... (1)
4C + 6P = 44............(2)
Now put the value of P in equation 2
4C + 6(9 - C) = 44
4C + 54 - 6C = 44
-2C = -10
C = 5
And, P = 4
hence, the number of cakes sell is 5
Answer:
The answer is: the second one
Step-by-step explanation:
(2x + 2)/y = 4w + 2
pass y to the right side 2x + 2 = y(4w + 2)
expand 2x +2 = 4wy + 2y
pass 2 to the right 2x = 4wy + 2y -2
pass 2 to the right x = (4wy + 2y - 2)/2
simplify x = 2wy + y - 1 or = 2yw + y -1
The mean is: 7.6
The range is: 7
The median is: 7
The mode is: 5
:)
Solution set is: (
)
Option B is correct
Step-by-step explanation:
We need to find the solution to system of equations
Let:
Putting value of y from eq(2) into eq(1)
So, value of x=7
Putting value of x into equation 1 to find the value of y:
So, value of y = 
Solution set is: ()
Option B is correct
