Which statement about the solution to the following system of equations is true?3x - 2y = 4
-6x + 4y = -8

A) There is no solution because the equation represents the same line
B) There is no solution because the equations have the same slope
C) There are infinitely many solutions because the lines have the same slope and different y-intercepts.
D) There are infinitely many solutions because the equations represent the same line

Answers

Answer 1

Answer: Let's solve and find out.

3x - 2y = 4
-6x + 4y = -8

To solve by elimination, multiply the top equation by 2 to cancel out y-terms.

2(3x - 2y = 4)
6x - 4y = 8

Now, add the equations together.

6x - 4y = 8
-6x + 4y = -8
+___________
0 - 0 = 0

Since we get that 0 = 0, this system has infinitely many solutions. Only graphs that represent the same line have infinitely many solutions, so...

Answer:
D) There are infinitely many solutions because the equations represent the same line

What's the conversion factor used to convert miles to yards

Answers

The required, formula for converting miles to yards: yards = miles x 1760.

The conversion factor used to convert miles to yards is 1760. This means that 1 mile is equal to 1760 yards.

To convert from miles to yards, simply multiply the length in miles by 1760. For example, 5 miles is equal to 8800 yards (5 x 1760 = 8800).

Here is the formula for converting miles to yards:

yards = miles x 1760

Here are some examples of converting miles to yards:

1 mile = 1760 yards

2 miles = 3520 yards

3 miles = 5280 yards

4 miles = 6960 yards

5 miles = 8800 yards

Angle x is the largest angle in triangle xyz. Angle y is the smallest angle. How does the sum of the measures of angles y and z compare to the measure of angle x

Answers

Knowing that the angles of the triangle has a total of 180 degrees, so we can have the following:

x + y + z = 180
y + z = 180 - x
or
x = 180 - y - z

In this approach, we can't give the actual values since there are no values presented.

Write a linear equation that passes through the point (2,-9) and has a slope of -5

Answers

Answer:

y = -5x + 1

Step-by-step explanation:

Given:

The slope m = -5 and point (2, -9)

Use point slope form:

y - y₁ = m(x - x₁), where (x₁, y₁) is the given point

So the equation is:

y - (-9) = -5(x - 2)
y + 9 = -5x + 10
y = -5x + 1

Answer:

Step-by-step explanation:

Given in the number of hours a group of contestants spent preparing for a quiz

The list shows as follows:

60 25 86 56 45 48 90 75 30 67 90 36 80 15 32 65 61

In ascending order this becomes

x 15 25 30 32 36 45 48 56 60 61 65 67 75 80 86 90

F 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2

Thus we have mode =90

All other entries have frequency 1 except 90
