What is the slope of a line that goes through 0,0 and 5,-1

djyliett [7]

Answer:

slope = -1/5

Step-by-step explanation:

The slope of a line between two points is ...

slope = (change in y)/(change in x)

= (-1 -0)/(5 -0) = -1/5

The slope of the line is -1/5.

What's 7/9 times something equals 640

aksik [14]

We'll use 'x' to represent that 'something.
7/9x=640.
Divide each side by 7/9 to isolate 'x'.
x = 822 6/7.

A marvellous spatuletail is flying at an elevation of 4294 \dfrac294924, start fraction, 2, divided by, 9, end fraction meters.

user100 [1]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as what is required is not stated.

However, since it deals with height of different elevations and these heights are represented by fractions, a possible question could be to calculate the difference between both elevations

Represent Marvellous Spatuletail with M and Asian crested ibis with A.

$M = 4\frac{2}{9}$

$A = 10\frac{1}{4}$

Calculating the difference (D).

To do this, we make use of absolute difference as follows:

$D = |M - A|$

Substitute values for M and A

$D = |4\frac{2}{9} - 10\frac{1}{4}|$

Convert fraction to improper numbers.

$D = |\frac{38}{9} - \frac{41}{4}|$

Take LCM

$D = |\frac{38*4-41*9}{36}|$

$D = |\frac{152-369}{36}|$

$D = |\frac{-217}{36}|$

Remove the absolute sign

$D = \frac{217}{36}$

$D = 6\frac{1}{36}$

Hence, the difference between both elevations is: $6\frac{1}{36}\ meters$

Another possible question is to determine which of the two is flying at a higher elevation or lower elevation

We have.

$M = 4\frac{2}{9}$

$A = 10\frac{1}{4}$

Compare the integer parts of both fractions.

10 > 4

So, A flies at a higher elevation.

Hence: Asian crested ibis flies at a higher elevation and Marvellous Spatuletail flies at a lower elevation.

3. The following are the values of a, b, and c that Edna, Luisa,

Kay [80]

Answer:

a = 2

b = 3

c = -5

Step-by-step explanation:

We are given Algebraic expression:

5-3x = 2x²

We rewrite it in standard form

2x² + 3x - 5

Algebraic form :

ax² + bx + c

Hence, the values of a, b, c is given below:

a = 2

b = 3

c = -5
