Solving systems of equations by substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
x = 2y - 5
-2x + 5y = 11
Step 2: Solve for y
Substitution
Substitute in x: -2(2y - 5) + 5y = 11Distribute -2: -4y + 10 + 5y = 11Combine like terms: y + 10 = 11Isolate y: y = 1Step 3: Solve for x
Define original equation: x = 2y - 5Substitute in y: x = 2(1) - 5Multiply: x = 2 - 5Subtract: x = -3Determine weather the following graph represents a function
Answer:
it doesn't because there are places where there are two y values which just doesn't work out.

Find the derivation of y=sin (2x2 + 3x-4)<br />a. -cos (4x +3) b. -(6x2+3) cos (2x3+3x-4) c. Cos (2x3+3x-4)<br />d. (6x3+3) cos (2x3+3)<br />
Let y = f(x)
f(x) = sin x
g(x) = (2x^2 + 3x - 4)
Use the chain rule.
We want y' = f' (g(x)) • g'(x).
y' = cos(2x^2 + 3x - 4) • (4x + 3)
Done.

How much fertilizer containing 30% nitrogen should be mixed with a fertilizer containing 10% nitrogen to get 10L of a fertilizer containing 12% nitrogen?
Answer:
1L of 30% fertilizer and 9L of 10% fertilizer
Step-by-step explanation:
Let x = the amount of fertilizer containing 30% nitrogen.
Let y = the amount of fertilizer containing 10% nitrogen
x + y = 10 because the two fertilizers together will be 10L
0.3x will be the amount of nitrogen in the 30% nitrogen fertilizer, and 0.1y will be the amount of nitrogen in the 10% fertilizer. If you add those together, you will get 12% of the nitrogen in the 10L mixture. This makes this equation:
0.3x + 0.1y = 0.12(10)
0.3x + 0.1y = 1.2
Now we have our two equations.
x + y = 10
0.3x + 0.1y = 1.2
We can use substitution to solve this system of equations.
x = 10 - y
Substituting this into the second equation, we have:
0.3(10-y) + 0.1y = 1.2
3 - 0.3y + 0.1y = 1.2
3 - 0.2y = 1.2
1.8 = 0.2y
9 = y
10 - 9 = 1L
There will be 9L of 10% nitrogen fertilizer and 1L of 30% nitrogen fertilizer.

Which description explains how the graph of f(x)=√x could be transformed to form the graph of g(x) = √x-6
horizontal shift of 6 units left
horizontal shift of 6 units right
vertical stretch by a factor of 6
vertical shift of 6 units up
Which equation represents the transformation of f(x)=|x| when effected by a vertical stretch of 3, a horizontal shift to the right 4 units, and a vertical shift up 2 units?
g(x)= 1/3 |x−4| + 2
g(x)= 1/3 |x+4| − 2
g(x)= 3 |x−4| + 2
g(x)= 3 |x+4| + 2
Answer:
b
c
Step-by-step explanation:
First question: x - 6 means there is a shift to the right.
Second Question: substitute the given values into the original equation for appropriate transformations.
Answer: 3 |x-4| + 2, because vertical stretch multiplies x, horizontal shifts are subtracted or added to x, and vertical shifts are added or subtracted to the entire function.
The movement of the curve in the graph is shifting of the curve in vertical or the horizontal direction.For the first function the graph horizontal shift of 6 units right and for the second function when it is vertical stretch of 3, a horizontal shift to the right 4 units, and a vertical shift up 2 units the transformation function is,
[tex]g(x)=3|x-4|+2[/tex]
Given-
The equation of the graph given in the problem is,
[tex]f(x)=\sqrt{x} [/tex]
Translation of the graphThe movement of the curve in the graph is shifting of the curve in vertical or the horizontal direction.
a) The equation of the graph when it is transferred is given as,[tex]g(x)=\sqrt{x-6} [/tex]
There is no change with the constant value. Thus the graph will not move in vertical direction. The change in variable of a unit result in the graph shift in horizontal direction.
As it shift -6 thus graph horizontal shift of 6 units right.
b) The given function is,[tex]f(x)=|x|[/tex]
Vertical stretch of 3 means multiply the function with unit 3.
[tex]g(x)=3|x|[/tex]
Horizontal shift to the right 4 units means the difference of 4 units in the variable,
[tex]g(x)=3|x-4|[/tex]
Vertical shifts up with 2 units means the addition of the constant 2.
[tex]g(x)=3|x-4|+2[/tex]
Hence, for the first function the graph horizontal shift of 6 units right and for the second function when it is vertical stretch of 3, a horizontal shift to the right 4 units, and a vertical shift up 2 units the transformation function is,
[tex]g(x)=3|x-4|+2[/tex]
