How do you add single digit numbers

Mathematics

Hi there!

This question isn't too hard.

To add with single digit numbers you just need to count.

You can regroup too, depending on what numbers you're using. I can give you some examples if you'd like!

1 + 2 = 3 because you need to just count. If I have one apple and you have two, count to see how many apples we have altogether. In this case, we have three apples.

What about 9 + 9? You would regroup because our answer is bigger than ten. If I have nine pennies and you have nine pennies, and we put them all together you'd have 18. Just count like before ^

Hope this helps!

Find a symbolic representation for f ^-1​(x).
Alexus [3.1K]

y = (9x) ^ (1/3)

exchange x and y  then solve for y

x = (9y) ^ (1/3)

cube each side

x^3 = 9y

divide each side by 9

1/9 x^3 = y

the inverse function is 1/9 x^3

Find all x-intercepts and y-intercepts of the graph of the function.<br> F(x)=x³-4x² - 4x + 16
Lady bird [3.3K]

Answer: (0;16)  (4;0)  (2;0)  (-2;0).

Step-by-step explanation:

Y-intercepts of the graph of the function F(x)=x³-4x² - 4x + 16:

x=0\\F(x)=0^3-4*0^2-4*0+16\\F(x)=16.\\Hence,\  (0;16).

X-intercepts of the graph of the function F(x)=x³-4x² - 4x + 16:

F(x)=0\\0=x^3-4x^2-4x+16\\0=(x^3-4x^2)-(4x+16)\\0=x^2*(x-4)-4*(x-4)\\0=(x-4)*(x^2-4)\\0=(x-4)*(x^2-2^2)\\0=(x-4)*(x-2)*(x+2)\\x-4=0\\x_1=4.\\Hence,\ (4;0)\\x-2=0\\x_2=2.\\Hence,\ (2;0)\\x+2=0\\x_3=-2.\\Hence,\ (-2;0).

Triangle ABC is reflected over the line y = x to produce triangle A'B'C'. What will be the coordinates of A'? A (2,−1) B (−2,−1)
zheka24 [161]

Answer:

when P(x,y) is reflected in y=x line then

P(x,y) = P(y,x)

A(2, -1)= A(-1, 2)

B(-2, -1) = B(-1, -2)

C(2, 1)= C(1, 2)

D(1,2)= D(2,1)
