Answer:

The error with mark’s work is that a negative times a negative will give a positive. So -3 times -5 is +15 not -15. Then 15 times -2 will get you -30.

Find the value of r (5,9) (r,7) m=-4
jolli1 [7]

Answer:

r = 11/2

Step-by-step explanation:

m = slope

slope, m = (y2 - y1)/(x2 - x1)

-4 = (7 - 9)/(r - 5)

cross multiply

-4(r - 5) = 7 - 9

clearing brackets

-4r + 20 = -2

-4r = -22

r = 22/4 = 11/2

Can someone please help? the value of a plot of land increases 8% every year. the value is $350000 now, and the owner wants to s
Andre45 [30]

The value of b in the exponential function which is formed by Shanna for the price of land is 8% or 0.08.

<h3>What is percentage increase ?</h3>

Percentage increase is the amount added to the initial value in the percentage part.

The value of a plot of land which is increases 8% every year has the current value of $350000.

The final value owner wants is $570000.  Shanna writes an exponential function of the form, to model the value,v, of the land in t years as,

v(t)=a\times b^t

Here, in this exponential function the value of a is fixed or initial term which is $350000 and the value of b is the constant term which is change factor. Here, the value of b is 8%.

b=8%

b=8/100

b=0.08

Thus, the value of b in the exponential function which is formed by Shanna for the price of land is 8% or 0.08.

Which are rational and irrational? Thanks in advance :)
DochEvi [55]

Answer:

3\frac{1}{2}-rational

\pi -irrational

-\frac{2}{3}-rational

\sqrt{16} -rational

\sqrt{3} -irrational

18-rational

0.625-rational

0.987987987...-rational

Step-by-step explanation:

Rational numbers:

-are all numbers you can write as a quotient of integers  \frac{a}{b} , b\neq 0

-include terminating decimals. For example, \frac{1}{8}=0.125

-include repeating decimals. For example, \frac{1}{3} =0.33333....

Irrational numbers:

-have decimal representations that neither terminate nor repeat. For example, \sqrt{2}=1.414213....

-cannot be written as quotients of integers
