Answer:
And if we rewrite this expression we got:
If the system have just one solution then we need the slope different and for this reason we can discard the options:
y = 4x-5
-2y = -8x - 10 equivalent to y =4x+5
2y = 8x - 10 equivalent to y = 4x -5
And then the correct answer would be:
y=-4x + 5
Step-by-step explanation:
For this case we have the following equation given:

Answer:
F is not a function
Step-by-step explanation:
There is more than 1 corresponding y coordinate per x coordinate

Answer:
9
Step-by-step explanation:
For studs 16" O.C., Chalberg will need 9: one at the beginning of each of the 16" spaces in the 96" width of the wall, and one at the end. That's a total of 6+1 = 7 studs.
The top and bottom edges of the wall are each 8', so will require 1 more board each.
The total number of boards Chalberg needs is 9.
Answer:
x=3
Step-by-step explanation:
Solve for x by cross multiplying.
Answer:
11 pounds of Guatemala Antigua coffee
9 pounds of Arabian Mocha coffee
Step-by-step explanation:
Guatemala Antigua coffee - $10.20 per pound
Arabian Mocha coffee - $13.00 per pound
First find the total profit from the 20 pounds of the new coffee blend.
20 × $11.46 = $229.20
Now set up an equation.
$10.20g + $13.00a = $229.20
Use guess and check to find the number of pounds of each type of coffee.
$10.20g + $13.00a = $229.20
$10.20(11) + $13.00(9) = $229.20
$112.20 + $117 = $229.20
$229.20 = $229.20
It checks out. So, they should mix 11 pounds of Guatemala Antigua coffee and 9 pounds of Arabian Mocha coffee.
Hope that helps.
