Answer:

see explanation

Step-by-step explanation:

To calculate 2f , multiply each of the components of f by the scalar 2

To add/ subtract, add/ subtract corresponding components

(a)

2f = \left[\begin{array}{ccc}2(4)\\2(1)\\\end{array}\right] = \left[\begin{array}{ccc}8\\2\\\end{array}\right]

(b)

f + g = \left[\begin{array}{ccc}4+5\\1+3\\\end{array}\right] = \left[\begin{array}{ccc}9\\4\\\end{array}\right]

(c)

2f - g = \left[\begin{array}{ccc}8-5\\2-3\\\end{array}\right] = \left[\begin{array}{ccc}3\\-1\\\end{array}\right]

What is the difference between a two step equation and a multi-step equation?
Step2247 [10]

Answer:

When solving a multi step equation, you use PEMDAS (parentheses, exponents, multiplication, division, add, subtract), and you also use PEMDAS when solving a multi step inequality. However, inequalities are tricky in the fact that if you multiply or divide by a negative number, you must flip the sign. And while normally there are 1 or 2 solutions to a multi step equation, in the form of x= #, you'll have the same thing, but with an inequality sign (or signs).

A two-step equation is an algebraic equation that takes you two steps to solve. You've solved the equation when you get the variable by itself, with no numbers in front of it, on one side of the equal sign.

hope it helped

Answer:

Width = 40ft

Step-by-step explanation:

Area of a rectangle = Length x Width

=> 1600 = 40 x W

=> 1600 = 40W

=> 1600/40 = 40W/40

=> 40 = W

So, the width is 40 ft

Find the value of each variable.
kap26 [50]

Answer:

EF = 18 in. & m∠F = 134 °

Step-by-step explanation:

Hi there,

In order to find the length of side EF, you should realize that this is an <u>isosceles triangle</u>. We know that two sides and two angles of this type of triangle are equal to each other. We also know that the lengths of the sides opposite of the congruent angles are equal to each other. Thus, we proved that length of side EF is equal to the length of side FG.

Therefore, EF is 18 inches because FG is 18 inches.

In order to find m∠F, you need to know that the sum of the angles in a triangle add up to 180°. You add all of the known angle values and subtract it by 180°.

m∠E + m∠G + m∠F = 180°

23° + 23° + m∠F =  180°

46° + m∠F = 180°

m∠F = 134°

Hope this explanation helps you understand this problem. Cheers.
