An inequality to model this would be
7x + 8y ≥ 336.
We multiply the number of minutes running, x, by the number of calories burned each minute by running, 7. We multiply the number of minutes swimming, y, by the number of calories burned each minute by swimming, 8. Adding these together, it needs to be greater than or equal to 336, since she wants to burn at least that many calories.
Answer:
43
Step-by-step explanation:
48/(2^3+4)*10.75
48/(8+4)*10.75
48/12*10.75
4*10.75
43

We need to put ur equation in y = mx + b form ...and the m will be ur slope and the b will be ur y int
so basically, we solve for y...
2x + y = 3....subtract 2x from both sides
y = -2x + 3
y = mx + b
y = -2x + 3......slope(m) = -2 and y int (b) = 3 <==
You can reword the equation 6x+y=9 to
Y=6x+9
Then plug-in y=6x+9 into the equation 2x+3y=-5
Plug this 2x+3(6x+9)=-5
2x+18x+27=-5
Then solve it from there
