Answer:
-5x + y = -27
Step-by-step explanation:
Equation: y+8 = -5(x+3)
Standard form is (ax + by = c)
We have to get x and y and their coefficients over to the left side of the equation, and all the single numbers to the right side.
y + 8 = -5 (x + 3)
y + 8 = -5x -15
y = -5x - 27
THE ANSWER IS :
-5x + y = -27
Answer:
y = 9
Step-by-step explanation: this is because when x is 5 and is multiplied by -6 u get -30. from there u substratc -30 from -57 and get -27. so y is 9
To calculate the percent of something I always think of it in decimals. 100% is 150% is 1.5. So 200% of something is basically times 2. If it's something that says a 50% INCREASE/DECREASE(key word) you multiply by .5 then add to the original number. Hope I helped
Answer:
x = 5 y = -5
Step-by-step explanation:
-7x - 3y = -20
-3y = 7x - 20
y = -7/3x + 20/3
3x + 6(-7/3x + 20/3) = -15
3x - 14x + 40 = -15
-11x = -55
x = 5
-7(5) - 3y = -20
-35 - 3y = -20
-3y = 15
y = -5
