Answer:

By "small numbers" you probably mean exponents. The exponent just represents how many times you multiply the number by itself. For example, 4^{3} means 4 x 4 x 4, which equals 64.

The "letters" are called variables. They represent an unknown value. The most common variables you'll see are x and y, which are used a lot in graphing. Variables are often used in equations. For example:

<em />

<em>"Maria wants to buy cupcakes, at $2.50 each. She only has 10 dollars. How many cupcakes can she buy?" </em>

You would use an exponent to solve this problem. If you make cupcakes "C" then you can say:

C (the # of cupcakes) times 2.50 (cost per cupcake) = 10.

(in shorter terms, 2.50c=10.)

You can then solve for "c" by dividing by 2.50 on both sides and you can then see that Maria has enough money to buy 4 cupcakes.

Hope this helps! :)

The small numbers in math shows that you have to mutiplies how much the power is. For Example, 5 with a power of 2 → 5² that's what it looks like.

Answer:

27,36,45

Step-by-step explanation:

Pythagorean theorem

a^{2} +b^{2} =c^{2}

6^{2}+ 9^{2}\\ =117\\\neq 12^{2}

7^{2}+ 10^{2}\\ =149\\\neq 12^{2}

16^{2}+ 18^{2}\\ =580\\\neq 25^{2}

27^{2}+ 36^{2}\\ =2025\\= 45^{2}

Contains the x intercept of 4x-y=8 and the point (-4,3)
nydimaria [60]
<span>1.       </span><span>4x –y = 8, the point (-4, 3)
Let’s say y = 0
=> 4x – 8
=> 4x / 4 = 8 /4
=> x = 2
So the point is (2 , 0).
Now, we have 2 forms, the (2,0) and the (-4, 3)
=> (y2 – y1)(x2 – x1) = m
=> m = (0 - 3)(2-(-4))
=> m = (0 - 3)(2+4)
=>  m = (-3)(6)
=> m = -1/2
Thus,
y = -1/2x + a
=> 0 = -1 + a so a = 1
y = -x/2 + 1</span>
