Answer:

\boxed {x = - \frac{9}{4}}

Step-by-step explanation:

Solve for the value of x :

-2(x + \frac{1}{4}) + 1 = 5

-Use Distributive Property:

-2(x + \frac{1}{4}) + 1 = 5

-2x + \frac{-2}{4} + 1 = 5

-Reduce the fraction \frac{-2}{4} to the lowest terms by canceling out 2 :

-2x + \frac{-2}{4} + 1 = 5

-2x - \frac{1}{2} + 1 = 5

- Convert the integer 1 to \frac{2}{2} :

-2x - \frac{1}{2} + 1 = 5

-2x - \frac{1}{2} + \frac{2}{2} = 5

-Since both fractions -\frac{1}{2} and \frac{2}{2} have the same denominator, you add the numerators together:

-2x - \frac{1}{2} + \frac{2}{2} = 5

-2x + \frac{1}{2} = 5

-Change the integer 5 to \frac{10}{2} and subtract \frac{1}{2} on both sides. Then, when both fractions have the same denominator, you subtract them, by subtracting the numerators:

-2x +  \frac{1}{2} -  \frac{1}{2} = \frac{10}{2}  -  \frac{1}{2}

-2x = \frac{9}{2}

-Divide by Multiplying 2 and -2 :

\frac{-2x}{-2} = \frac{9}{2 (-2)}

x = \frac{9}{-4}

-Rewrite the answer:

x = \frac{9}{-4}

\boxed {x = - \frac{9}{4}}

What is the slope of the line represented by 3x - 7y = 28?
olya-2409 [2.1K]
Answer: 3/7

Why?
Reorganize the equation 3x-7y=28 you get
Y=3/7x-4
Because y=mx+b and m=the slope this shows that the slope is 3/7

Hope this helps :D

Fatima plotted one side of a heptagon on a grid. the points (-8,1) and (-8,8) are joined to form a side of the heptagon. Fatima
Reil [10]

The general formula for the distance between two points is

d(A,B) = \sqrt{(A_x-B_x)^2 + (A_y-B_y)^2}

Anyway, if A and B have the same x or y coordinates, this formula can be simplified. For example, in this case the two points have the same x coordinate of -8, so the following part of the formula simplifies:

(A_x-B_x)^2 = (-8-(-8))^2 = (-8+8)^2 = 0^2 = 0

So, we're left with

d(A,B) = \sqrt{(A_y-B_y)^2}

but the square root of a square is the absolute value of the object being squared:

d(A,B) = \sqrt{(A_y-B_y)^2} = |A_y-B_y|

which is this case means |1-8| = |-7| = 7

which is the correct length of the side.
