Answer:

x = 3, y = 11

Step-by-step explanation:

Given

2x + 3xi + 2y = 28 + 9i

Compare coefficients of like terms on both sides.

Comparing i terms

3x = 9 ( divide both sides by 3 )

x = 3

Comparing constant terms

2x + 2y = 28 ← substitute x = 3

2(3) + 2y = 28

6 + 2y = 28 ( subtract 6 from both sides )

2y = 22 ( divide both sides by 2 )

y = 11

If p(x)=2x^2-4x and q(x)=x-3 what is (p*q)(x)
Tanya [424]

Answer: 2x³-10x²+12x or 2x(x²-5x+6)

Step-by-step explanation:

(p*q)(x) means p(x) and q(x) multiplied together.

(2x²-4x)(x-3)

2x³-6x²-4x²+12x

2x³-10x²+12x

You can also factor this by taking out a 2x.

2x(x²-5x+6)

Write an equation for the line parallel to the given line that contains C<br> C(2,6); y= -4x + 7
MrRa [10]

Answer:

y=-4x+14

Step-by-step explanation:

step 1

Find the slope of the given line

we have

y=-4x+7

This is the equation of the given line in slope intercept form

The slope is m=-4

step 2

Find the slope of the line parallel to the given line

we know that

If two lines are parallel, then their slopes are the same

therefore

The slope of the line parallel to to the given line is m=-4

step 3

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=-4

C\ (2,6)

substitute

y-6=-4(x-2)

step 4

Convert to slope intercept form

y-6=-4(x-2)

isolate the variable y

y-6=-4x+8

y=-4x+8+6

y=-4x+14
