If 4x = 28 , find the value of 29-5x

Levart [38]

First you would solve 4x=28. Divide both sides by 4 and you'll get x= 7. Then you plug in the 7 in replacement for the x in the equation, 29-5x and you'll get as an answer -6!!

Solve x -2/3(3x - 4) + 3x = 5/6 is x -19/6, 11/6, 21/6, 29/6

Tanzania [10]

Answer:

x=-11/12

Step-by-step explanation:

Given an equation for x

x -2/3(3x - 4) + 3x = 5/6

We are asked to find the value of x.

We use equation rules to solve

To get rid of denominator in fraction, let us multiply the whole equation by 6.

6x-4(3x-4) +18x = 5

Simplify:

-6x+18x+16 =5

12x = 5-16 = -11

x = -11/12

Find parametric equations through point P=(2,2,7) in the direction of the vector v = (44, 14, -20)?

ycow [4]

9514 1404 393

Answer:

(x, y, z) = (2+44t, 2+14t, 7-20t)

Step-by-step explanation:

One way to write parametric equations for line L is ...

L = P + t·<em>v</em>

where P is the given point and <em>v</em> is the given direction vector. Using that form, we have ...

(x, y, z) = (2+44t, 2+14t, 7-20t)

If you like, you can remove a common factor of 2 from the coefficients of t.

(x, y, z) = (2+22t, 2+7t, 7-10t)

Is the answer to this math problem A?

jarptica [38.1K]

The inverse of any function is when you switch the position of the 'y' and 'x' variables, like such:

$x = \sqrt[3]{y+10} \\x^3=y+10\\y = x^3-10\\f^{-1} (x)=x^3-10$

Hope that helps!

Help help help somebody please. I don’t know what to don

KatRina [158]

Answer:

-5

Step-by-step explanation:

f(x)=x-8

f(x)=-13

We know that f(x)=y for some number y so we have x-8=-13.

add 8 to both sides to obtain

x=-5
