X is the number of songs and Y the number of pics
1:X+y=11
2:4x+2y=24
1: x=11-y
Lets replace x in 2:
4(11-y) +2y=24
44-4y+2y=24
44-24= 4y-2y
20= 2y
Y=20/2
Y=10
Lets replace y in 1
X+10=11
X=11-10
X=1

Answer: The slope is 4/9 or -4/-9.
Step-by-step explanation:
(1,5)
(10,9) Find the difference in the y values and divide it by the difference in the x values.
5-9= -4
1- 10= -9
-4/-9= 4/9
so the slope is 4/9
Using the slope we could also find the y-intercept and write the equation.
5=4/9 (1) + b where b is the y-intercept
5= 4/9 + b
-4/9 -4/9
b= 41/9
Now we will have the equation y= 4/9 + 41/9
Answer:
Option D. − 8/5
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
we have the points
(−1, 7) and (4, −1)
substitute in the formula
years because it’s longer than any of those
Answer:
Kenya’s equation has infinitely many solutions
Step-by-step explanation:
we have
Solve for x
Eliminate the parenthesis
Group terms that contain the same variable
Combine like terms
---> is true for any value of x
therefore
Kenya’s equation has infinitely many solutions
