Find the value of x. 56° 57° 85 2x 4x

Mathematics
1 answer:
erma4kov [3.2K]3 years ago
8 0

Answer:

56

Step-by-step explanation:

Simplifying

x + 7x = 56 + 8

Combine like terms: x + 7x = 8x

8x = 56 + 8

Combine like terms: 56 + 8 = 64

8x = 64

Solving

8x = 64

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '8'.

x = 8

Simplifying

x = 8

What is the equation for the line in slope-intercept form? 20 18+ Enter your answer in the box. 16+ 14+ 112+ NO+ 6 4 2 - 20-18 -
sasho [114]

The slope of the line represents that the remainder of the goal decrease by 8 for each card sold.

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

The line passes through the point (1, 8) and (2, 16), hence:

y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-8=\frac{16-8}{2-1}(x-1)\\\\y=8x

The equation of the line is given by y =8x

How many solutions does this system have?
goblinko [34]

A system of equation may have one, zero or infinitely many solutions

The system of equation has no solutions

The systems of equation are given as:

y = -6x - 5

-2y +7 = 12x

Substitute -6x - 5 for y in -2y +7 = 12x

-2(-6x - 5) +7 = 12x

Open brackets

12x + 10 +7 = 12x

12x + 17 = 12x

Subtract 12x from both sides of the equation

17 = 0

The above equation is not true i.e.17 \ne 0

Hence, the system of equation has no solutions
