You would need to add 7x to both sides.

Answer:

Option a) Adding 7x to both the sides

Step-by-step explanation:

Given is an equation linear in one variable x.

-7x -5= x + 3

To solve this equation we have to bring x terms on one side and constants on the other side.

Subtracting 5 from both sides will not eliminate the constant -5 hence wrong.

Adding x to both sides will make right side as 2x instead of eliminating x.

Combining like terms will give -7x-x not -7x+x hence incorrect

Adding 7x to both sides gets rid of x term on the left.

Hence this option is right answer

What are the coordinates of the point on the directed line segment from (-6, -6)(−6,−6) to (9, -1)(9,−1) that partitions the seg
GrogVix [38]

Answer:

(0, -4)

Step-by-step explanation:

The coordinates of the points from which the directed line segment extends = (-6, -6) to (9, -1)

The ratio the required point partitions the line = 2 to 3

The formula for finding the coordinate of a point that partitions a line AB into a ratio 'a' to 'b', where the coordinates of, A = (x₁, y₁) and B = (x₂, y₂) is given as follows;

\left(\dfrac{a}{a + b} \times (x_1 - x_2)+ x_1, \ \dfrac{a}{a + b} \times (y_1 - y_2)+ y_1 \right)

Therefore, the required point is located as follows;

\left(\dfrac{2}{2 + 3} \times (9 - (-6))+ (-6), \ \dfrac{2}{2 + 3}\times (-1 - (-6))+ (-6) \right) = (0, -4)

The coordinates of the point is (0, -4)

A + 2 ÷ -24 = -4 what does A equal​
sergeinik [125]

Step-by-step explanation:

A + 2 ÷ (-24) = -4

A - 1/12 = -4

A = -4 + 1/12

A = -48/12 + 1/12

A = -47/12

A ≈ -3,91
