Answer:
a.<55, -27>
Step-by-step explanation:
The given vectors are u = <7, -3>, v = <-9, 5>.
We want to find 4u - 3v.
We substitute the vectors and multiply by the scalars.
4u - 3v=4<7, -3>-3 <-9, 5>.
4u - 3v=<28, -12>- <-27, 15>.
4u - 3v=<28--27, -12-15>
4u - 3v=<55, -27>

Answer:
square
Step-by-step explanation:
A line that has a 0 slope is a horizontal line.....it is represented by y = a number.....so a line with a zero slope WILL touch the y axis.....it will touch the y axis at y = 1
just so u know...it is a vertical line that does not touch the y axis
so ur answer is y = 1.....this line has no slope but it touches the y axis

2.923----> move the decimal three times to the left because that is how many spaces you have to the right on the actual equation until the next decimal.
The product of 0.79x 3.7 is 2.923. And, the decimal was moved three times to the right of the equation because of the number of spaces until the next decimal which then allows you to move the decimal three times to the left on the product.
