Solve 12x^2+5x-4=12^2x+6
Answers
Answer:
okay so we need to solve for x.
--
FIRST STEP: 12x^2+5x-4=12^2x+6 would turn into x2 + 5x - 4 = 2x + 6 so it'd have equal bases.
SECOND STEP: move any number with "x" in it to the left side. it ends up as x2 + 3x - 4 = 6
THEN, we use the AC method to eliminate any unnecessary numbers.
you should end up with ( x - 2) (x + 5) = 0
SO, the answer is your third option. ( x = 2, x = -5)
Step-by-step explanation:
Answer:
x = 2, x = -5
Step-by-step explanation:
[tex] {12}^{ {x}^{2} + 5x - 4 } = {12}^{2x + 6} \\ (Bases\: are\: equal\: so\: exponents\: \\will\:also\:be \: equal) \\ \implies \: {x}^{2} + 5x - 4 = 2x + 6 \\ \\ \implies \: {x}^{2} + 5x - 4 - 2x - 6 = 0\\ \\ \implies \: {x}^{2} + 5x - 2x - 4- 6 = 0\\ \\ \implies \: {x}^{2} + 5x - 2x - 10 = 0\\ \\ \implies \:x(x + 5) - 2(x + 5) = 0\\ \\ \implies \:(x + 5)(x - 2) = 0 \\ \\ \implies \:x + 5 = 0 \: \: or \: \: x - 2 = 0 \\ \\ \implies \:x = - 5 \: \: or \: \: x = 2[/tex]

What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).
As per the given triangles M and M'.
If we take point B then the all vertices of triangle M and M' will make a straight line with point B as shown below.
Thus, point B will be the center of dilation.
Hence "The triangle M"s center of dilation will be at B".

Sixteen is five less than a number.
Which steps would you take to translate the statement?
Replace “is” with =, “less than” with –, and “a number” with n to get 16 = 5 – n.
Replace “is” with =, “less than” with +, and “a number” with n to get 16 = n + 5.
Replace “is” with =, “less than” with –, and “a number” with n to get 16 = n – 5.
Replace “is” with =, “less than” with ÷, and “a number” with n to get 16 = 5 ÷ n.

Answer:
The correct option would be the 3rd one
If you want to find 5 less than a number you are subtracting
so 5 less than 20 would be 15, so 20 - 5
since 16 is five less that means whatever the equation equals it will be 16 which is why 16 is in the first part

Answers
Answer:
5
Step-by-step explanation:
12/20 = 3/x
solve for x
x=5
Answer: x is 5
Step-by-step explanation: These two triangles are similar (meaning same shape but different size.) To find x, we must first decrease the scaling. The original triangle is 3 and x sides. Being scaled, it is now 12 and 20. 12 divided by 4 is 3, so that's the first side, and being equivalent, 20 divided by 4 is 5, so therefore the triangle has been scaled by 4 units. Therefore x side is 5.
Which of the following (x,y) pairs is the solution for the system of equations x + 2y = 2 and -2x
+y = 16?
Answers
Answer:
(-6,4)
Step-by-step explanation:
make sure x's or y's are the same and opposite signs
x + 2y = 2 and -2x +y = 16
multiply 2 with x + 2y = 2 so that there is 2x
2 * (x + 2y = 2) = 2x + 4y = 4
2x + 4y = 4
-2x +y = 16
--------------------
5y = 20
y = 4
put y = 4 back into one of the equations
-2x +y = 16
-2x + 4 = 16
-2x = 12
x = -6
