Answer:46 by 46 that is how much for two tshirts will cost
Answer:
Step-by-step explanation:
Answer: $418
Step-by-step explanation:
This is because you find 5% of $440 which is 22. Then you subtract 22 from 440 which is 418, thus the answer
Answer: 30
Step-by-step explanation: Start off by multiplying the two numbers.
3 x 10 = 30.
30 is a common multiple. Find any multiples below 30. Let’s start off using the biggest number of the two, which is 10, to see what other numbers can be multiples. 10, 20, and 30 can be. 3 can’t be divided into 10 or 20, so your least common multiple is 30.
Answer:
![y-7=3(x-9)](https://tex.z-dn.net/?f=y-7%3D3%28x-9%29)
Step-by-step explanation:
The form of equation of line given in the problem is the point-slope form of a line. That is given by:
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
We need
and m (denoted by boxes)
is the y coordinate of the first set of points.
The first coordinate pair is (9,7), so
would be 7
![y_1=7](https://tex.z-dn.net/?f=y_1%3D7)
Now, the slope (m).
It has formula
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
So, x_1 = 9
y_1 = 7
x_2 = 4
y_2 = -8
Substituting, we get the slope to be:
![m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{-8-7}{4-9}\\m=\frac{-15}{-5}\\m=3](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5Cm%3D%5Cfrac%7B-8-7%7D%7B4-9%7D%5C%5Cm%3D%5Cfrac%7B-15%7D%7B-5%7D%5C%5Cm%3D3)
Hence, the equation of the line in point-slope is:
![y-7=3(x-9)](https://tex.z-dn.net/?f=y-7%3D3%28x-9%29)
