How do I know my multiples ​

Mathematics
1 answer:
Archy [21]3 years ago
5 0

One way to make it easier to multiply, pick a number from a multiplication problem. Then, add the amount of times of the other number.

Example:

6 x 8 = ?

8 = Chosen Number

So, add 8, 6 times.

8 + 8 + 8 + 8 + 8 + 8 = ?

? = 48

Which, 6 x 8 does equal 48.

The circle C has centre A(2,1) and passes through the point B(10,7). Find and equation for C
Semmy [17]
The equation of a circle:
(x-h)^2+(y-k)^2=r^2
(h,k) - the coordinates of the centre
r - the radius

A(2,1) - \hbox{the centre} \\
h=2 \\ k=1 \\ \\
(x-2)^2+(y-1)^2=r^2 \\ \\
\hbox{passes through B(10,7)} \\
x=10 \\
y=7 \\ \\
(10-2)^2+(7-1)^2=r^2 \\
8^2+6^2=r^2 \\
64+36=r^2 \\
r^2=100 \\ \\
\hbox{the equation:} \\ \boxed{(x-2)^2+(y-1)^2=100}

Y=kx+1 <br> M(2,-7) <br><br> What is K
Karo-lina-s [1.5K]

Answer:

K = 5m+y/x

Step-by-step explanation:

Let's solve for k.

y=kx+1m(2−7)

Step 1: Flip the equation.

kx−5m=y

Step 2: Add 5m to both sides.

kx−5m+5m=y+5m

kx=5m+y

Step 3: Divide both sides by x.

kx/x = 5m+y/x

Therefore, k = 5m+y/x
