k(x)=6x-12; k(x)=18
please help idk what the answer is

Answers

Answer 1
ok so you would plug in 18 for the x so it would be 6(18)-12 and then 6x18 is 108 and 108-12=96 so your answer is 96

write the linear equation from the given information in slope intercept form passing through (-2,8) and perpendicular to y=2x+5​

Answers

Answer:

y  =  [tex]-\frac{1}{2}[/tex] x + 9

Step-by-step explanation:

Given parameters:

  Coordinates = (-2,8)

Equation of the line  y  = 2x + 5;

Unknown:

Linear equation of a line perpendicular = ?

Solution:

From the given expression, a line perpendicular will have a negative inverse of the slope given.

           y  = 2x + 5

Equation of a line  is y = mx + c;

y and x are the coordinates

  m is the slope

   c is the intercepts

    y  = 2x + 5 ;

 The slope is 2;

  A line perpendicular will have a slope of [tex]-\frac{1}{2}[/tex]  

 Since y = 8 and x  = -2, let us find c;

     8  = 2 x [tex]-\frac{1}{2}[/tex]  + c

    8 = -1 + c

     c  = 8+1 = 9

The equation of the line is;

       y  =  [tex]-\frac{1}{2}[/tex] x + 9

Find f(-2)

Answers

Step-by-step explanation:We are given with two functions: f(x) = 9x - 2 and g(x) = -x + 3. In this problem, the expression of f(g(x)) is asked. We first substitute g(x) to f(x) resulting to f(-x + 3) = 9 (-x + 3) - 2  equal to -9x + 27 -2 or f(g(x)) = -9x + 25.

The answer is -9x+25 hope this helps

Find the value of x.

Answers

Answer:

I'm not sure but I think that x= 53. All

Here I will explain you friend
So we know the exterior angle is 127
I am marking this triangle ABC
So 127+angle B=180( Linear pair)
So angle B = 180-127
Angle B =53
Also in this question it is AB = AC
So it is an isosceles triangle
So angle B = Angle X ( angles opposite to the equal side of the triangle are also equal)
So Answer is x =53
Hope it helps you!

Answers

Answer:

−1.01

Step-by-step explanation:

Simplify the expression!

Answer: -1.01

Step-by-step explanation:

a double negative equals a positive. -(-1.9) = 1.9

-0.85 + 1.9 = 1.05

when you have a positive number and add a negative number you just subtract the negative number from the positive.

1.05 + - 2.06 = 1.05 - 2.06

1.05 - 2.06 = -1.01

the answer is -1.01

find z and x

please help i’ll mark the first one or whoever right brainliest

Answers

Answer:

z=97 x=21

Step-by-step explanation:

so straight angles always equal 180°

And assuming that your lines are parallel, the angle under angle z should be 83° just like the angle above angle z

There for to solve for x, first subtract 83 from 180 because that's what that angle is equal to.

Now that you have the equation 4x+13 and you know that it's equal to 97 you can solve it just like a normal inequality.

4x+13=97

4x=84

x=21
