$10.22 this is the answer for you..............
Answer:
0.8
Step-by-step explanation:
4/5 which is 0.8, or cross multiply to get the answer.
U just add one more zero to the as many 1 hundred
Since interest=investment*interest rate*time in years for simple interest, we know that there are 2 separate investments. If the amount invested at 6% simple interest is x dollars and the amount invested at 8% is y dollars, then we know that x+y=6000 since she spent all 6000 dollars on only 2 separate investments. Subtracting y from both sides, we get that 6000-y=x. In addition, we know that her interest for the 6% interest rate is x*0.06*1 as well as y*0.08*1 for the 8% simple interest. Since the total interest is 410$, we know that x*0.06*1+y*0.08*1=410. Since y=6000-x, we plug that in to get x*0.06+(6000-x)*0.08=410. Using the distributive property to expand, we get x*0.06+480-0.08x=410=-0.02*x+480. Subtracting 480 from both sides, we get -0.02*x=-70. After that, we can multiply both sides by -50 (since -0.02 times -50 is 1) to get x=3500=amount invested at 6%. Since the amount invested at 8% is 6000-x, that equals 6000-3500=2500
Answer:
B
Step-by-step explanation:
Hey There!
they are asking for the equation in slope intercept form
Slope intercept form is y=mx+b
where m equals slope and b equals y intercept
to find the slope we do change in y over chang in x
as y goes up 2 x goes down 5 so the slope would be -2/5
the y intercept is at (0,4) so the y intercept is 4
now we add everything together and get that the equation in slope intercept form is
y=-2/5x+4
so we can conclude that the answer is B
