Answer:

The value of A is 4.

Step-by-step explanation:

Consider the provided quadratic equation.

4x^2-20x+3=0

Subtract 3 from both sides.

4x^2-20x+3-3=-3

4x^2-20x=-3

Now take 4 common from the left side of the above equation.

4(x^2-5x)=-3

Compare the above equation with A(x^2 - 5x) = -3

By the comparison it is clear the value of A is 4.

Hence, the value of A is 4.

Determinewhether the two lines areparallel, perpendicular, neither.X-3=6Y = 3x +4
Brums [2.3K]

we have the lines

x-3=6

x=6+3

x=9

this is a vertical line (parallel to the y-axis)

The slope is undefined

and

y=3x+4

The slope is m=3

Compare their slopes

1) Their slopes are not equal -----> are not parallel lines

2) Their slopes are not negative reciprocal -----> are not perpendicular lines

therefore

Which value of c would make the following express completely factored? 8x+cy
Artist 52 [7]
The answer is B, 7.

\sf 8x+2y

We can factor a 2 out of this: \sf 2(4x+y)

\boxed{\sf 8x+7y}

We can't factor anything.

\sf 8x+12y

We can factor a 4 out of this: \sf 4(2x+3y)

\sf 8x+16y

We can factor an 8 out of this: \sf 8(x+2y)

So your answer is B, 7.

Inessa [10]

Answer:

1. 30

Step-by-step explanation:

First, place the numbers from least to greatest.

11,13,23,37,45,58

Then, find the middle number (or two middle numbers).

In this case, the middle numbers are 23 and 37.

Third, we find the mean of these numbers.

23+37=60

60/2=30

So your answer is 30.

Repeat this method for the other problems.
