Answer:
4 in^2
Step-by-step explanation:
The rate is 1:5
<span>y -3x = 2
y = 3x + 2 so slope = 3
parallel lines, slope is the same so slope = 3
</span><span>passes through (6,1)
</span>y = mx + b
b = y - mx
b = 1 - (3)(6)
b = 1 - 18
b = -17
equation
y = 3x - 17
hope it helps
Answer:
5 years
Step-by-step explanation:
The formula for the amount of simple interest (I) at rate r on principal P for t years is ...
I = Prt
Filling in the given numbers and solving for t, we have ...
3150 = 7000·0.09·t
3150/630 = t = 5 . . . . . divide by the coefficient of t
The loan was for 5 years.
X^2 + 2x - 15
factors into (x+5)(x-3)
set this equal to 0 and get that x=-5 and x=3
<span>The
<u>correct answer</u> is:
350 ml.
Explanation<span>:
Let x be the amount in the fifth container.
The mean is found by adding all of the amounts together and dividing by the number of containers (in this problem, 5). We know that the total from the other 4 containers is 2750; add this to x, our unknown number. Then we divide by 5 to arrive at our answer of 620.
Algebraically,

<span><span>
To solve, multiply both sides by 5:
</span></span>
<span><span>
Subtract 2750 from both sides:
2750+x-2750=3100-2750
x=350.
There are 350 ml in the fifth container.</span></span>
