Answer:

The numbers that meet these conditions are -3, -2 and -1.

This means that the wording of the question is somewhat ambiguous:

The <em>lowest</em> of the three numbers is -3.

The <em>smallest</em> however is -1.

You may need clarification on which of those is being asked for.

Step-by-step explanation:

Let's call those numbers a, b and c, with a the smallest and c the largest. We're told two key things here:

1) The sum of the smaller two integers is two more than seven times the largest integer.  In other words a + b = 7c + 2

2) We're looking for three consecutive integers, which means that we can define them with a single variable.  If the smallest one is a, then the others are a + 1 and a + 2.

We can take those and put them together, giving us the equation:

a + (a + 1) =  7(a + 2) + 2

Which we can then solve for a:

a + (a + 1) =  7(a + 2) + 2

2a + 1 = 7a + 14 + 2

2a - 7a = 14 + 2 - 1

-5a = 15

a = -3

Since a is -3 and also the smallest, we can then say that the numbers are -3, -2 and -1.

If you're asking for extrema, like the previous posting

well

\bf f(x)=\cfrac{-x}{x^2+5}&#10;\\\\\\&#10;\cfrac{df}{dx}=\cfrac{(x^2+5)+2x^2}{(x^2+5)^2}\implies \cfrac{df}{dx}=\cfrac{5+3x^2}{(x^2+5)^2}\impliedby &#10;\begin{array}{llll}&#10;using\ the\\&#10;quotient\ rule&#10;\end{array}

like the previous posting, since this rational is identical, just that the denominator is negative, the denominator yields no critical points

and the numerator, yields no critical points either, so the only check you can do is for the endpoints, of 0 and 4

f(0) = 0        <---- only maximum, and thus absolute maximum

f(4) ≈ - 0.19  <----  only minimum, and thus absolute minimum

zzz [600]

Answer:

Sasha can look at the graph and check to see that when she plots the points on the graph, they end up as a straight line. She can also draw a table to test the values and see if when you divide y/x you get the same answer for all of them.

0.75y-1.5y+0.5=5 I need answers to this asap
Mnenie [13.5K]

Answer:

y = -6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

0.75y−1.5y+0.5=5

0.75y+−1.5y+0.5=5

(0.75y+−1.5y)+(0.5)=5(Combine Like Terms)

−0.75y+0.5=5

−0.75y+0.5=5

Step 2: Subtract 0.5 from both sides.

−0.75y+0.5−0.5=5−0.5

−0.75y=4.5

Step 3: Divide both sides by -0.75.

Hope this helps!

:)

Drupady [299]
Mu=80, sigma=39, X=85
Z=(X-mu)/sigma = 5/39=0.128=0.13
P(X<=85)= 0.5517 (from Z-table)
so, P(X>85)=1-0.5517=0.4483 approx. thats 44.8% probability.
