Answer:

4(3x+y)^2

Step-by-step explanation:

36x^2+24xy+4y^2

=9*4x^2+6*4xy+4y^2

=4(9x^2+6xy+y^2)

=4(3x+y)*(3x+y)

=4(3x+y)^2

KIM [24]
You substitute the given value of y into the equation
8x+4(3x+8)=12
Solve the equation for x
x= -1
Substitute the given value of x into the equation y=3x+8
y=3x (-1)+8
Solve the equation for y
y=5


Answer: (x= -1) (y= 5)

Elina [12.6K]

Answer: English is the preferred one.

Step-by-step explanation:

When you are dealing with percentage problems you just have to do a simple rule of three to answer the question, we have that our 100% is the total number of students:40, and 40% of them report that keyboarding is their favorite class, while 24 students say that English is their favorite class, now we just have to convert:

We clear the X and our function would look like this:

Now we know that 16 kids prefer keyboarding over the 24 that prefer English, since there are more kids that prefer English that is the favorite class.

Which of the following lines is parallel to the line y=(-1/4)x+5?
Blizzard [7]

Answer: y=(-1/4)x -3

Step-by-step explanation:

Which of the following lines is parallel to the line y=(-1/4)x+5

Two lines are parallel to each other if they have the same slope,

Slope of line 1 = slope of line 2

Looking at y=(-1/4)x+5,

we will compare it with the slope-intercept equation, y= mx+c

Slope of y=(-1/4)x+5 = -1/4

Now let's examine the options to see the one such that has the same value with our slope , -1/4

1) y=4x+7

From this equation, slope = 4

4 × -1/4= -1

This means lines (-1/4)x+5 and y=4x+7 are not parallel to each other since their slopes are unequal

2)y=-4x-5, slope = -4

This means lines (-1/4)x+5 and y=4x-5 are not parallel to each other since their slopes are unequal.

3)y=(-1/4)x-3

slope = -1/4

This means lines (-1/4)x+5 and y= (-1/4)x-3 are parallel to each other since their slopes are equal. This means equations y=(-1/4)x-3 and y=(-1/4)x+5

are parallel.

In conclusion, line y=(-1/4)x-3 is parallel to y=(-1/4)x+5
