Answer:
x=1
Step-by-step explanation:
Simplifying
6x + 5 = 11x
Reorder the terms:
5 + 6x = 11x
Solving
5 + 6x = 11x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-11x' to each side of the equation.
5 + 6x + -11x = 11x + -11x
Combine like terms: 6x + -11x = -5x
5 + -5x = 11x + -11x
Combine like terms: 11x + -11x = 0
5 + -5x = 0
Add '-5' to each side of the equation.
5 + -5 + -5x = 0 + -5
Combine like terms: 5 + -5 = 0
0 + -5x = 0 + -5
-5x = 0 + -5
Combine like terms: 0 + -5 = -5
-5x = -5
Divide each side by '-5'.
x = 1
Simplifying
x = 1
Answer:
105m²
Step-by-step explanation:
15+6=21
21÷2=10.5
10.5x10=105
Answer:
128 m^2
Step-by-step explanation:
You have 5 sides of a cube on the bottom with length 4
5 * 4x4 = 80 m^2
then four triangles on top
area of triangle = 1/2 base * height base = 4 height = 6
4 * 1/2 ( 4)(6) = 48 m^2
summed = 128 m^2
RemarkThe very first thing you should do with a question like this is get the graph. Then you will know what you are looking for. I have provided you with such a graph. Your table should center around -2 ≤ x ≤ -1
So let's set up a table and see what we get. Start with y = x + 5
x x + 5
-1 4
-1.25 3.75
-1.5 3.5
-1.75 3.25
-2 3
Do the same thing for - (3)^x + 4 See below to see how this is entered your calculator
x -(3)^x + 4
-1 3.66
-1.25 3.75
-1.5 3.8
-1.75 3.85
-2 3.89
ConclusionWhen x = - 1.25 y = 3.75 for both graphs. <<<< Answer
FootnoteYou may not be familiar with how to put this in your calculator. This is the way I would do it. I'm only doing it for y = -(3^x) + 4
Let x = - 1.25
