Let's Simplify X to equal 1 by dividing by 100. then we divide 420 by 100 to get 4.2, so y=4.2 when x=1, we then multiply by each by 11.

y = 46.2
x = 11

-6x-5y=-6<br>3x+6y=24<br>solve for x and y​
zhannawk [14.2K]

Answer:

x= -4 and y=6

Step-by-step explanation:

-6x-5y=-6     -equation 1

3x+6y=24       -equation 2

Solving the equation 1 to get the value of

To solve such type of equations that have two unknown variables, find the value of one variable in terms of the other from any one of the equation and put the value in the second equation which will give the value of both the variables

Solving Equation 2 to find x

3x+6y=24

3x=24-6y

x=(24-6y)/3     =8-2y              equation 3

Putting this value of x in the equation 1

-6x-5y= -6

-6(8-2y)-5y= -6

-48+12y-5y= -6

7y= -6+48

7y= 42

y= 42/7 = 6, y=6

Putting the value of y in equation 3 to find the value of x

x=8-2y= 8-2(6)

x= -4

Raphael graphed the functions g(x) = x + 2 and f(x) = x – 1. How many units below the y-intercept of g(x) is the y-intercept of
muminat
These functions are in the form y=mx+b
Therefore, we know that in g(x) = x+2, the y-intercept is 2. 
For f(x) = x-1, the y-intercept is -1. 
Now find the difference between them. 
2-(-1)= 3
The y-intercept for f(x) is 3 units below g(x)

The total amount is 12 ounces therefore you can use that as your denominator.
4 ounces out of it are vanilla and the other 8 are chocolate.
4 out of 12 is vanilla . This can also be written as 4/12.
4/12 can be your first fraction.
The second one can be a simplified version of 4/12.
The simplified version would be 1/3.
Your two fractions would be 4/12 and 1/3.

Hope This Helps You!
Good Luck Studying :)

grandymaker [24]
4.94 ounces because there are 0.035 ounces in 1 gram so 0.035 times 140 would give you 4.94 ounces
