Answer:
Step-by-step explanation:
[1] 3x - 4y = -24
[2] -x - 16y = -52
Graphic Representation of the Equations :
-4y + 3x = -24 -16y - x = -52
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -16y + 52
// Plug this in for variable x in equation [1]
[1] 3•(-16y+52) - 4y = -24
[1] - 52y = -180
// Solve equation [1] for the variable y
[1] 52y = 180
[1] y = 45/13
// By now we know this much :
x = -16y+52
y = 45/13
// Use the y value to solve for x
x = -16(45/13)+52 = -44/13
Solution :
{x,y} = {-44/13,45/13}
<span>Last week, Rosa ran 6 1/4 laps around the lake. Clara ran 1/5 as many laps around the lake as Rosa did. How many laps around the lake did Clara run?</span>
Where is the graph but in this case the y intercept would be -2 and you slope is 6 so go up 6 and to the right one and go down six and to the left one and thats what the graph should look like
Answer:
B. 4
Step-by-step explanation:
The sign
means greater than or equal to
The sign > just means greater than
4 is a solution for x
4, because 4 is equal to 4, but not a solution for x>4, because 4 is not greater than 4
Hope this helps! :)
