Answer:
y=6/5x+11
Step-by-step explanation:
Perpendicular lines have the opposite sign and reciprocal of the original line. Since the y-intercept is 11 we know that it is 6/5x+11
The pair of equations:
y = x + 4
y = -2x - 2
To solve the system of equation by substitution, you would substitute one variable for it's equivalent expression. Combining the pair of equations into one equation in only one variable. The easiest way to do this is by substituting out the variable y because it is already alone on one side of the equal sign. Substitute the y in the second equation for: x+4
x+4 = -2x - 2
solve for x
x + 2x = -2 -4
3x = -6
x = -2
now use the value for x to find y by putting into either equation.
y = x + 4
y = (-2) + 4
y = 2
solution is: (-2, 2)
Answer:
see the explaination
Step-by-step explanation:
let x be 3:3:5
3x:3x:5x
3x is splice cookies
3x is snickerdoodle cookies
5x is no bake cookies
where 5x is equal to 45
x is equal to 45÷5=9
so x is equal to 9
now,
3x = 3×9=27
3x = 3×9=27
5x = 45 (given)
now add all, total cookies =27+27+45
=99 cookies
so there are total 99 cookies in a cookie mix
