Answer:

Infinite Solutions

Step-by-step explanation:

x + 2y = 10

6y = 3x - 30

To solve for x and y we use substitution method

Let's solve the first equation for x

x + 2y = 10

Subtract 2y on both sides

x = 10 - 2y

Now plug in x in second equation

6y = -3x + -30

6y = -3 (10-2y) - 30

6y = -30 + 6y - 30

6y = 6y

Both sides are the same, so both x and y have infinite solutions.

Answer:

#2024

Step-by-step explanation:

My greatest dream,

Is to spend the rest of my life with you.

Laughing and sharing,

Making wonderful memories in all that we do.

To grow together, to be strong as one,

To talk, to communicate,

To unite when things come undone.

Said I don't understand,

How you don't got a man,

You want me in your bed,

because I've been in your head.

To be your best friend,

And for you to be mine,

To support one another,

When we give things a try.

To be honest and faithful,

To be kind and comforting,

Generous and respectful.

For now and for always

A man on a 135-ft vertical cliff looks down at an angle of 16°13' and sees his friend.

iren2701 [21]

A) Use the trigonometric function and ratio cos(x) = A/H. (Adjacent/Hypotenuse)
1. cos(x) = 135/H
2. H*cos(16°) = 135
3. H = 135/cos(16°)
***Make sure calculator is in degree mode***
4. H = 140.44 ft (rounded to two decimal places)
________

b) Use the function and ratio tan(x) = O/A (Opposite/Adjacent)
1. tan(x) = O/A
2. tan(16°) = O/135
3. 135*tan(16°) = O
4. O = 38.71 ft (two decimal places)

Good luck!

What is the term of a 7-term geometric series if the first term is -11 the last term is -45,056 and the common ratio is -4

shutvik [7]

I assume you mean to ask how to find the sum of the seven terms?

You have

$a_2=ra_1$
$a_3=ra_2=r^2a_1$
$a_4=ra_3=r^3a_1$
...
$a_7=ra_6=r^6a_1$

So the sum is

$a_1+ra_1+r^2a_1+\cdots+r^6a_1=a_1(1+r+r^2+\cdots+r^6)=a_1\times\dfrac{1-r^7}{1-r}$

You know that $a_1=-11$ and $r=-4$ , so the sum is equal to

$-4\times\dfrac{1-(-4)^7}{1-(-4)}=-13108$

Which set of ordered pairs is not a functions?

Anit [1.1K]

Answer:

Step-by-step explanation:

X values cannot repeat in a function, 3 is used as an X value twice in A, and therefore cannot be a function.

If this is graphed, you can use the vertical line test, if a vertical line on any point goes through other points, it is not a function.

In this case, just check if X repeats.
