Answer:

no solution.

Step-by-step explanation:

We have been given the system of equations

6x-3y=5...(i)

y-2x=8...(ii)

Write both equations in slope intercept form y = mx +b

For equation (i)

6x-3y=5\\-3y=-6x+5\\\\y=2x-\frac{5}{3}

The slope is 2 and the y- intercept is -5/3

For equation (ii)

y-2x=8\\\\y=2x+8

The slope is 2 and the y-intercept is 8

Since, both the equations have equal slope and different y - intercepts. Hence, the lines are parallel.

Therefore, we can say that the system have no solution.

Answer: Annie has 49 Quarters

Explanation:
Sarah has 21 more quarters than Annie.
As shown, It says That Sarah has 28 quarters.
So, if Sarah has 21 more, it means you add 21 + 28
Resulting in 49.

Hope this helps you! If available please give me a Branliest. It is much appreciated!

What is the length of the diagonal of a square with a side that measures 11 centimeters
timofeeve [1]
A square has 4 equal sides
use pythagroeas theorem since a square has 4 right angles

a^2+b^2=c^2
a=b because the sides are equal (11)

11^2+11^2=c^2
242=c^2
square root both sides
11√2=c

the diagonal legnth is 11√2 centimiters

State the equation of the line described.
nikdorinn [45]

Answer:

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes. This means that when you multiply the slopes of the perpendicular lines, its product = -1.

Given the linear equation, y = -9x - 1, and the point, (-3, 7):

Since the slope of the given linear equation is: m1 = -9, then it means that the slope of the other line (m2) = 1/9:

m1 × m2 = -1

-9 × 1/9 = -1

Next, we need to find the y-intercept of the other line. The y-intercept is the point on the line where it crosses the y-axis, and has coordinates (0, <em>b</em>). It is also the value of the y-coordinate when its corresponding x-coordinate = 0.

Using the given point, (-3, 7), and the slope of the other line, m2 = 1/9:

We need to substitute these values into the slope-intercept form, y = mx + b, to solve for the y-intercept, (b):

y = mx + b

7 = 1/9(-3) + b

7 =   -1/3 + b

Add 1/3 to both sides of the equation to solve for b:

7 + 1/3  = 1/3 -1/3 + b

22/3 = b

Therefore, the y-intercept (b) = 22/3.

The linear equation of the other line is: y = 1/9x + 22/3
