Answer to question 1 is D
answer to question 2 is A
Answer:
x = 6
y = 4
Step-by-step explanation:
Let the two numbers be x and y
<u><em>Condition 1:</em></u>
7x+3y = 54 -----------(1)
<u><em>Condition 2:</em></u>
x = 2+y -----------------(2)
<em>Putting (2) in (1)</em>
=> 7(y+2)+3y = 54
=> 7y+14+3y = 54
=> 10y = 54-14
=> 10y = 40
<em>Dividing both sides by 10</em>
=> y = 4
<em>Now putting y = 4 in eq(2)</em>
=> x = 2+4
=> x = 6

Your x-intercept is (12/5,0) and your y-intercept is (0,-4)
Answer:
f(3)= 156
Step-by-step explanation:
f(x)=12(3x+4)
f(x)=12(3(3)+4) =12(9+4) = 12(13) = 156
f(3)= 156
