Let the amount invested at 4% be = x
Let the amount invested at 3% be = y
Given is:
or
.... (1)
As, total income for the two investments is $194, so equation is:
....(2)
Putting value of x from (1) in (2)




And x=5200-y

Hence, money invested at 4% is $3800 and money invested at 3% is $1400
T=(h*5)+6.5 should be it because it is the number of hours multiplied by 5 days and then you add the 6.5 hours
Answer:
no 1 answer is 24
Step-by-step explanation:
no 2 answer is -5
To find the answer you could do 256 divided by 4 and that gives you the answer which is 64 to check the math you can multiply 64 times 4 and if it comes out as 256 then you have your answer.
Hope this answers your question!
Answer:
B
Step-by-step explanation:
let equation be y = mx + b.
2x + 4y = 6
1/2x + y = 3/2
y = -1/2x + 3/2
since perpendicular, their gradients produced equals neg 1.
so,
m = -1/(-1/2) = 2
sub (6, 4):
4 = 2(6) + b
b = -8
therefore, eqn is y = 2x - 8
