Answer:

1/4

Step-by-step explanation:

the equation for slope is (y2 - y1) / (x2 - x1)

so the equation is (4-8)/(3-19)

= -4/-16

= 4/16

= 1/4, therefore, the slope is 1/4 or 0.25 as a decimal

avanturin [10]

Answer:

1. 88 - b

Since there is 88 birds and a few of them flew away. You know b represents the amount of birds present.

2. 73 + d

Since he is earning d (amount of dollars) so what you have to do is add the amount of dollars, d, to the orginial amount, which is 73.

3. 23 x g

Since Kurt has 23 miles. If he drives 23 miles to a gallon and we have g gallons then we would multiply to find how far he can drive.

H31 = -0.2

Step-by-step explanation:

The matrix sum H is the element-by-element sum of corresponding elements of F and G. For example, H31 = F31 +G31 = -4.7 +4.5 = -0.2.

For repetitive calculations using the same formula, it is convenient to do them using a spreadsheet.

Someone help please! D:

Dahasolnce [82]

Answer:

D) (10,22)

Step-by-step explanation:

based on given slope and point, the linear equation is <em>y = 9/5x + 2</em>

plugging in x-and-y values only results in a true statement for option D

example:

22 = 9/5(10) + 2

Does 22 = 18 + 2? Yes

What are the values the values of a and b?

Setler [38]

The segment marked 20 is the geometric mean of the two pieces into which it splits the hypotenuse. You get the proportion

$\frac{20}{a} = \frac{21}{20}$

Solving,

$21a =(20)(20) \\ 21a = 400 \\ a = \frac{400}{21}$

To find b, use the fact that b is the geometric mean of the whole hypotenuse, 21 + a, and the part that is attached to it, a.

$\frac{b}{a} = \frac{21+a}{b}$

A little arithmetic shows that $21+a = \frac{841}{21}$ .

$\frac{b}{\frac{400}{21}} = \frac{\frac{841}{21}}{b} \\ b^2 = \frac{336400}{441} \\ b=\frac{580}{21}$
