Mathematics
1 answer:
oee [108]1 year ago
5 0

Answer:

(a): 26.1

(b): 27.9

Please see below for the steps.

Step-by-step explanation:

(a):

Use points (0,0) and (3, 78.3)

Use slope formula. The slope formula is also used to find average rate of change (just so you know).

y2-y1/x2-x1

78.3-0/3-0=78.3/3=26.1

Answer for (a) is 26.1

(b):

Use points (4, 147.6) and (9, 287.1)

Use slope formula.

y2-y1/x2-x1

287.1-147.6/9-4=139.5/5=27.9

The answer for (b) is 27.9

Hope this helps!

Please mark as brainliest if correct!

Have a great day!

Write a rational inequality with the solution: (-2,-1)U(1, oo)
serg [7]

Answer:

\displaystyle \frac{x^2+3x+2}{1-x}

Step-by-step explanation:

<u>Rational Inequality</u>

We are given the solution of rational inequality:

(-2,-1) U (1,∞)

The first set suggests a limited zone than can be obtained by a quadratic equation of the form:

(x-a)(x-b)

Where a and b are the roots of the equation, which coincide with the endpoints of the interval. Thus, to get the interval, we can use:

(x+2)(x+1)

Operating:

x^2+3x+2

The second set is an open infinite interval, that can be modeled as a third binomial that changes signs in x=1 and is in the denominator, so x=1 is not included.

Thus, one possible inequality is:

\mathbf{\displaystyle \frac{x^2+3x+2}{1-x}

PLEASE HELP!!!<br> THIS IS DUE SOON
Hoochie [10]

Answer:

It's 65

Step-by-step explanation:

The reason is because the whole thing needs to be 180 right.

So one of the sides is 67

D would have to be 65 because of the angle and also it is less then F.

E is 48 because it is cut.

So the answer would be 65

I hope this helps!

Please show step by step <br> I don’t know how to do this
Pepsi [2]

Answer:

4=1

Step-by-step explanation:

2(n + 2) = 4n + 1 - 2n

2n + 4 =4n - 2n + 1

2n + 4 = 2n + 1

<em>add -2n to each side</em>

2n-2n+4=2n-2n+1

0+4=0+1

4=1

idk if this is right myself but this is want i found on internet, i searched it up for 1 hour and this is the ans they gave me...
