Answer:
518 / 3.
Step-by-step explanation:
(74 / 3) * 7 = (74 * 7) / 3 = 518 / 3 = 172 and 2/3 = 172.6666666667.
Hope this helps!
Answer:
(-4;2)
Step-by-step explanation:
1. if y=1/2 x+4, then 2y=x+8; it is possible to re-write as x-2y+8=0;
2. if x+4y=4, it is possible to re-write it as x+4y-4=0;
3. if x-2y+8=0 and x+4y-4=0, then x-2y+8=x+4y-4; ⇒ -2y+8=4y-4; ⇒ 6y=12; ⇔ y=2.
4. if y=2, then it is possible to substitute its value into any equation given in the condition:
x+4y=4 (substitution y=2); ⇒ x+8=4; ⇒ x= -4.
5. finally x= -4; y=2. It means (-4;2)
PS. the suggested solution is not the only way to resolve this task.
I would estimate 29 miles because 57-28=29 and y is in the middle. It would also be a good idea to write this kind of problem out on paper.

Answer:
For x=1 substituting in f(x) the value of x
f(1)=-3(1)+1 = -2
For x=0 substituting in g(x) the value of x
g(0)=3^(0) =1
Finally, we have to find for what value of x the function f(x) gives -8
f(x) = -8
-8 = -3x+1
-3x=-9
x=3
