Answer:
i am not to positive but i think its C
Step-by-step explanation:
You subtract the intial from the final. your answer is0.94grams
Well the +7 also effects your graph but the coefficient 4 determines the stretch or compression of your graph. A higher coefficient compresses your graph more.
4x + 3y = 26
x = 3/2y + 2
solving for y:
4 (3/2y + 2) + 3y = 26
6y + 8 + 3y = 26
9y + 8 =26
9y = 18
y = 2
solving for x:
x = 3/2(2) + 2
x = 3 + 2
x = 5
done.
