Answer 1

Answer:

see explanation

Step-by-step explanation:

A column vector has the form [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]

Following the direction of the arrow , the x- displacement = - 3 and y- displacement = 2 , then column vector is

[tex]\left[\begin{array}{ccc}-3\\2\\\end{array}\right][/tex]

h + k

= [tex]\left[\begin{array}{ccc}4\\-3\\\end{array}\right][/tex] + [tex]\left[\begin{array}{ccc}-2\\-1\\\end{array}\right][/tex] ← add corresponding elements from each vector

= [tex]\left[\begin{array}{ccc}4-2\\-3-1\\\end{array}\right][/tex]

= [tex]\left[\begin{array}{ccc}2\\-4\\\end{array}\right][/tex]

Step-by-step explanation:

Answer:

Write - 1.5y = 4.5x - 9 in standard form .​

Answers

The standard from of the equation - 1.5y = 4.5x - 9 is 3x + y = 6.

What is an equation?

A mathematical equation is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given equation is - 1.5y = 4.5x - 9. The standard form of an equation is given as:-

ax + by = c

Reduce the equation -1.5y = 4.5x - 9 in standard form:-

-1.5y = 4.5x - 9

4.5x + 1.5y = 9

3x + y = 6

Therefore, the standard from of the equation - 1.5y = 4.5x - 9 is 3x + y = 6.

You would write it as 29^w :) mark me brainliest!

Answer:

I would assume that there is more to this question somewhere on the paper. w seems to be the variable you have to find. Check if you have any more info near that question that would help you find the value of w, so that you can find out what 29 to the power of w is.

There should be an equation somewhere to solve for the value of w.

If that is the only information provided for that question, then it seems like a typo, I guess.
