PLZZZ HELP ME.I WOULD RLLY APPRECIATE IT

Mathematics
1 answer:
tamaranim1 [39]2 years ago
7 0

Answer:

$2

Step-by-step explanation:

x = daylily

y = geranium

1x + 5y = 22

13x + 1y = 30

Multiply second equation by 5 and subtract the two equations.

1x + 5y = 22

- (65x + 5y = 150)

-64x = -128

x = 2

So one daylily costs 2 dollars

Find the equation of an exponential function in the form y = ab^x, given the points (0, 3) and (2, 108/25). Please simplify your
lilavasa [31]

We have the equation:

y=a\cdot b^x

We know two points and we will use them to calculate the parameters a and b.

The point (0,3) will let us know a, as b^0=1.

\begin{gathered} y=a\cdot b^x \\ 3=a\cdot b^0=a \\ a=3 \end{gathered}

Now, we use the point (2, 108/25) to calcualte b:

\begin{gathered} y=3\cdot b^x \\ \frac{108}{25}=3\cdot b^2 \\ 3\cdot b^2=\frac{108}{25} \\ b^2=\frac{108}{25\cdot3}=\frac{108}{3}\cdot\frac{1}{25}=\frac{36}{25} \\ b=\sqrt[]{\frac{36}{25}} \\ b=\frac{\sqrt[]{36}}{\sqrt[]{25}} \\ b=\frac{6}{5} \end{gathered}

Then, we can write the equation as:

y=3\cdot(\frac{6}{5})^x

PLEASE HELP ME IM BEGGING YOU IT IS EASY Consider the two groups listed below. Which statement describes the sets? (2 points) ho
miskamm [114]
Note that mailing address is unique, but houses are not, meaning that you can't have house A and house B both referencing the same address.

So, in order to have a valid function, any two points on the function cannot have the same x value that lands on different y.

With this property mentioned, it's clear to see that
(house, address) is NOT a function; however, (address, house) is a function, since same x lands on multiple y values is a valid onto function. (a house that have multiple addresses)

If all of the angles of a hexagon are congruent, then what is the measure of each angle?
Nastasia [14]
<span>he total number of internal degrees is (n-2)*180 = 4*180 = 720 degrees.
-----
let a = one of the congruent angles.
you have:
angles 1, 2, and 3 = a.
-----
if a = 2 * angle 4, then angle 4 = 1/2 * a
-----
if a = 1/2 * angle 5, then angle 5 = 2 * a
-----
we have:
angle 1 = a
angle 2 = a
angle 3 = a
angle 4 = 1/2 * a
angle 5 = 2 * a
angle 6 = 115
</span><span>-----
since the sum of the angles is equal to 720, we have:
3*a + 2*a + 1/2*a + 115 = 720
combine like terms to get:
5.5 * a + 115 = 720
subtract 115 from both sides to get:
5.5 * a = 720 - 115 = 605
divide both sides by 5.5 to get:
a = 720/5.5 = 110
-----
angle 1, 2, and 3 are each 110 degrees.
angle 4 = 55 degrees
angle 5 = 220 degrees
angle 6 = 115 degrees
-----
the question is:
What is the measure of the smallest angle?
the answer is:
55 degrees.</span>
