Line A; y=3x +6 Line B: y =6-3x
Line C: y=17-x/3 Line D: y= 3x-1/3​


Please I need help!!!!

Answers

Step-by-step explanation:

line A and D are parallel because they have the same koeficient 3=3

line C is perpendicular to line A because

k1*k2=-1

3*(-1/3)=-1

which is a true statement

Answer:

a) Line D is parallel to line A

b) Line C is perpendicular to line A

Step-by-step explanation:

Line A has a slope of 3 and y intercept of 6

Line C is perpendicular to A as perpendicular lines have negative reciprocal slopes. Slope of C is -1/3

Line D is parallel to A as parallel lines have identical slopes but different y intercepts. Slope of D is 3 and y intercept is -1/3

Line B mirrors Line A over the y axis. It's slope is the negative of A and it has an identical y intercept.

1.3 x 9.16? Multiplying decimals​

Answers

One option (that I would use):

Ignore the decimals and multiply 13 x 916.

    9 1 6

  x    1 3

 2 7 4 8

 9 1 6 0

1 1 9 0 8

OK, now take into account there were a total of three digits to the right of decimal points (3, 1, and 6), so your answer also needs three digits to the right of your decimal point.

Find the value of x in the isosceles triangle shown below.

Answers

Answer:

Step-by-step explanation:

ΔABD ≅ ΔACD    {A S A congreunt}

∠ADB ≅ ∠ADC   {CPCT}

∠ADB + ∠ADC = 180   {linear pair}

2∠ADB = 180

∠ADB = 180/2

∠ADB = 90

∠ADB = ∠ADC = 90.

So, now we can use Pythagorean theorem to find x

x² = 8² - 2²

   = 64 - 4 = 60

x = √60

Write an equation for a line parallel to y = − 2 x + 4 and passing through the point ( 2 , 1 )

Answers

Answer:

x=2y

Step-by-step explanation:

y=-2x+4 is perpendicular to the line which passes through (2,1). We know that we can use the formula y=mx+c to find the gradient of the line with the equation y=-2x+4, which will give you -2. The product of the gradient of two perpendicular lines is always -1. So the gradient of the line which passes through (2,1 ) is -½.

Now,to find the equation of the line,we use the formula y-y1=m(x–x1)which will give you the answer 2y=x when solved.

Step-by-step explanation:

Identity used: [tex]a^{2}-b^{2} = (a + b)(a -b)[/tex]

81 = 9*9 = 9²

a = x^2 and  b =9

Then again 9 = 3*3.In this way, (x² - 9 ) can be again factored

[tex]x^{4} - 81 = (x^{2})^{2}-9^{2}\\\\=(x^{2} + 9)(x^{2} - 9)\\\\=(x^{2}+9) (x^{2} -3^{2})\\\\= (x^{2} + 9}(x+3)(x-3)[/tex]
