-4x + 6y = 12
x + 2y = -10
First solve for x in the second equation
x + 2y = -10
x = -10 - 2y
Now we have a value for x so we can substitute it into the other equation
-4 (-10 - 2y) + 6y = 12
Now solve for y
40 + 8y + 6y = 12
40 + 14y = 12
14y = -28
y = -2
Now we have a value for y that we can plug into one of the original equations so we can solve for x
x + 2y = -10
x + 2(-2) = -10
x - 4 = -10
x = -6
Your solution set is
(-6, -2)
Answer:
120 lb of soybean meal
200 lb of cornmeal
Step-by-step explanation:
S = pounds of soybean meal
C = pounds of cornmeal
S + C = 320 → C = 320 – S
0.16S + 0.08C = 0.11 × 320 = 35.2
16S + 8C = 3520
16S + 8(320 – S) = 3520
16S + 2560 – 8S = 3520
8S + 2560 = 3520
8S = 960
S = 120
C = 320 – 120 = 200

Answer:
7 and 6
Because in math, a coefficient is a number used to multiply a variable. Here, the variable is M and R therefore the coefficient is 7 and 6.
Solution:
Given:
To get the product of the polynomial; we use the distributive property of multiplication.
Therefore, the product of the polynomials is;
