What is the answer to this

olasank [31]

Three times the variable m minus four is equal to fourteen.

Another way could be:

Four less than three multiplied by m is equivalent to fourteen.

The first way I put it is simpler but if you really want to impress your teacher then I suggest going with the second way.

Also if you are looking to solve the equation then it would be:

3m - 4 = 14

+4 +4

------------

3m = 18

----- -----

3 3

m = 5

Hope that helped :-)

Solve by completing the square 3x^2-7x-1

docker41 [41]

Answer:

$x=\frac{7+\sqrt{61}}{6},\:x=\frac{7-\sqrt{61}}{6}$

Step-by-step explanation:

$a=3,\:b=-7,\:c=-1:\quad x_{1,\:2}=\frac{-\left(-7\right)\pm \sqrt{\left(-7\right)^2-4\cdot \:3\left(-1\right)}}{2\cdot \:3}$

$x=\frac{7+\sqrt{61}}{6},\:x=\frac{7-\sqrt{61}}{6}$

If f(x) = g(x) - 2 , then * g(x) = f(x) - 2 f(x) = g(x) + 2 g(x) = f(x) + 2

shusha [124]

Answer:

g(x) = f(x) + 2

Step-by-step explanation:

To move the two to the other side of the equation, you have to add the two to both sides of the equation. The 2 cancels out on the g(x) side, and a 2 is added to the f(x) side.

How do i solve this

NISA [10]

Both angles equal 73, according to the vertical angle conjecture. To solve for x:

(1+2x)=73
2x=72
x= 36

(a) Solve 7( k - 3 ) = 3k - 5

babymother [125]

A) $7(k-3)=3k-5\\ 7k-21=3k-5\\ 7k-3k=-5+21\\ 4k=16\\ k=\frac { 16 }{ 4 } \\ k=4$

b) $(2x+3)(x-8)\\ 2{ x }^{ 2 }-16x+3x-24\\ 2{ x }^{ 2 }-13x-24$

c) $\frac { 7-3f }{ 4 } =2\\ 7-3f=4\cdot 2\\ 7-3f=8\\ -3f=8-7\\ -3f=1\\ f=-\frac { 1 }{ 3 }$
