Create an equation that has exactly one real solution. 6(3x+4)-x=_x+3

OleMash [197]

Answer:

$x(x+5)=x^2-3x+8$

Step-by-step explanation:

There are infinite cases of equations with exactly one real solution. To create something worth the space, this one should suffice

$x(x+5)=x^2-3x+8$

Operating

$x^2+5x=x^2-3x+8$

Simplifying

$5x=-3x+8$

Joining like terms

$8x=8$

Solving

x=1

Testing the result

$1(1+5)=1^2-3(1)+8=>6=6$

The difference of a number multiplied by 2 tens and 3 sevens is 119. What is the number?

Elan Coil [88]

Your question is not clearly stated. Do you mean the difference between 10 * 10 * x, and 7 * 7 * 7 *x ? Then the number is x = 119/243. That's about 0.48971... in decimal form.

It's confusing when you say the "difference of a number". Differences are BETWEEN two numbers. See what I mean?

If f(x)=3x+2and g(x)=x^2-9 find (f-g)(x)

mel-nik [20]

Step-by-step explanation:

If f(x)=3x+2and g(x)=x^2-9

find (f-g)(x)

f(x)- g(x) = [3x + 2] - [x^2 - 9]

= -x^2 + 3x + 11

ABC is reflected across x = 1 and y = -3. What are the coordinates of the reflection image of B after both reflections?A. (-7, -

Dima020 [189]

Answer:

The correct option is C.

Step-by-step explanation:

From the given figure it is noticed that the coordinates of B are (-5,-7).

If ABC is reflected across x = 1, then

$(x,y)\rightarrow(1-(x-1),y)$

$(x,y)\rightarrow(2-x,y)$

$(-5,-7)\rightarrow(2+5,-7)$

$(-5,-7)\rightarrow(7,-7)$

If ABC is reflected across y =-3.

$(x,y)\rightarrow(x,-3-(y-(-3)))$

$(x,y)\rightarrow(x,-6-y)$

$(7,-7)\rightarrow(7,-6-(-7))$

$(7,-7)\rightarrow(7,1)$

Therefore option C is correct.
