Let the number be Y .
Y is seven
less than 5 times another (let that other be X)
Y=7-5X
sum of both Y and X minus 4 gives one
Y+X-4=1
now solve both equations .

5x+3y=30 find the slope intercept form, slope, and y=intercept
nordsb [41]
You’d rewrite it in slope-intercept form, y=mx+b
So the answer is y=-5/3x+10
Then you can point out the slope and y-intercept after you put it in the form.
Slope = -5/3
Y-intercept = 10

Hopefully this helps!

Jude Enjoys Eating Potato Chips. He likes to place 3 chips together in a stack to make interesting flavours. If he only has one
frez [133]

Using the combination formula, it is found that he can make 4 different stacks.

The order in which the balls are selected is not important, as stated in the problem. hence the <em>combination formula</em> is used to solve this question. If the order was important, then the permutation formula would be used.

<h3>What is the combination formula?</h3>

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by:

C_{n,x} = \frac{n!}{x!(n-x)!}

In this problem, he has four flavors, and will choose three of them for the stacks, hence the number of different stacks is given as follows:

C_{4,3} = \frac{4!}{3!1!} = 4

He can make 4 different stacks.

What is the remainder when $2^3 \cdot 4^5 \cdot 6^7 \cdot 8^9$ is divided by 13?
Lorico [155]

Answer:Hint:

the remainder is 2.

Step-by-step explanation:

23≡1 mod 7 and 33≡−1 mod 7.

Edit: The only thing you need from the modular arithmetic is that

a⋅b mod 7=(a mod 7)(b mod 7) mod 7,

meaning the remainder of a product is the remainder of the product of remainders. This is self-evident as a⋅b must have the same remainder as (a−7k)⋅(b−7l).

Since exponentiation is just repeated multiplication, we can write

230⋅320=(23)10⋅(33)6⋅32≡110⋅(−1)6⋅9=9
