Answer:
y = 3x - 5
Step-by-step explanation:
The equation is given in the form
y = 3x + 4
that is
y = mx + b
So, we can say:
m = 3
This is the slope (m).
Parallel lines have equal slopes, so we can say the line parallel will have the equation:
y = 3x + b
We are given that it passes through (2,1), so we plug in respective values of x and y and solve for b:
y = 3x + b
1 = 3(2) + b
1 = 6 + b
b = 1 - 6
b = -5
So, the equation is:
y = 3x - 5
Answer:
x is the 9 multiple = 9x
Step-by-step explanation:
- Let x is the numbers of flour tortillas packages
- Let y is the numbers of corn tortillas packages
=> the total packages : x + y
Given that the ratio of the number of packages of corn tortillas to the total number of packages on the shelf was 7 to 16, it means:
<=> 
= 
<=> 16y = 7x+7y
<=> 9y = 7x
<=> x = 
since both x and y are integers y is in the form of 7k where k∈N so
x = 9k
So x is the 9 multiple.
Hope it will find you well.
Let the first number be x.
Therefore second number is (x+2).
Therefore third number is (x+4).
Therefore forth number is (x+6).
Hence,
(x+x+2+x+4+x+6+x+8)/4 = 15
(4x+12)/4 = 15
x+3 = 15
x = 12
So,
The number is 12, 14, 16, 18.
