How do I solve for x? -3x+7=1

Mathematics

Answer:

x=8/-3 or 2.6

Step-by-step explanation:

You have to isolate the "x" so move the +7 to the other side of the equation and you get this:

-3x=1+7

Now you can simplify and add 7 plus 1 which is 8

the equation should looks like this now:

-3x=8

Then to have x by itself you divide -3 on both sides.

-3 divided by -3x just leaves the x there and -3 divided by 8 is just 8/-3 or in decimal form it's 2.6

-3x/-3= x

8/-3= 8/-3 or 2.6

x= 8/-3

I'm not really good at explaining but I hope it helped :/

Answer:

x=2

Step-by-step explanation:

              -3x+7=1

subtract 7 from both sides: -3x+7-7=1-7

simplify: -3x=-6

divide both sides by -3:  \frac{-3x}{-3}=\frac{-6}{-3}

simplify: x=2

Use the given function to find the indicated value(s) of x. (Enter your answers as a comma-separated list.)
Nady [450]

Answer:

For f(x) = √(2·x + 2) - √(x + 18), at f(x) = -1 the possible x-values includes;

-0.757, -17.5

Step-by-step explanation:

Given that the function is f(x) = √(2·x + 2) - √(x + 18)

The value of 'x' when f(x) = -1, is given as follows;

-1 = √(2·x + 2) - √(x + 18)

-1² = (√(2·x + 2) - √(x + 18))² = 3·x + 20 - 2·√(2·x + 2)×√(x + 18)

1 = 3·x + 20 - 2·√(2·x + 2)×√(x + 18)

2·√(2·x + 2)×√(x + 18) = 3·x + 20 - 1 = 3·x + 19

2·x² + 38·x + 36 = (3·x + 19)/2

2·x² + 38·x + 36 - (3·x + 19)/2 = 0

4·x² + 73·x + 53 = 0

From which we get;

x = (-73 ± √(73² - 4 × 4 × 53))/(2 × 4)

x ≈ -0.757, and x ≈ -17.5

Drag and drop the correct volume of the cylinder into the box to find the volume of the figure. Use 3.14
Furkat [3]

Answer:

2923.34 in^3

Step-by-step explanation:

Volume = Pi x (r) ^2 x height

PI =3.14,

, R = 7inch (d =radius /2 >> 14/2)

H =19 inch

Volume = 3.14 x 49in^2 x 19 inch

= 2923.34 in^3
