Answer:

x = −1/13 and y = 33/13 or 2 7/13

Step-by-step explanation:

x+2y=5

x+2(6x+3)=5

x+12x+6=5

13x+6=5

-6 -6

13x= -1

/13 /13

x= -1/13

y=6x+3

y=6(-1/13)+3

y= 33/13

y= 2 7/13

Determine whether theses lines are parallel, perpendicular or neither

belka [17]

Answer:

Lines 2 and 3 are parallel with slope (-2/3) and different y intercepts, and both are perpendicular to line 1 (-1) / (3/2) = (-2/3)

Step-by-step explanation:

Parallel lines have the same slope

Perpendicular lines have negative reciprocal slopes

line 1: 6x - 4y = 2

line 1: 4y = 6x - 2

line 1: y = (3/2)x - 0.5

line 2: y = (-2/3)x - 6

line 3:3y = -2x + 4

line 3: y = (-2/3)x + 4/3

Factorize 8x²+10x-12 = ??? Juste tell me if(4x-3) (x+2) is the right answer please.

MrMuchimi

No it is wrong
the product of it is
4x²+5x-6
so you have to multiply by 2
the naswer is 2(4x-3)(x+2)

6. a) Calculate the areas of the three squares. b) Is the triangle a right triangle? Explain. 3 cm 4 cm 2 cm

viktelen [127]

Answer

The total area of the squares = 29 square cm

The triangle is not a right-angled triangle

Step-by-step explanation:

We are given three squares

The first square has a length of 4cm

The second square has a length of 3cm

The third square has a length of 2cm

Part A

Total area = Area of square 1 + Area of square 2 + Area of square 3

Area of a square = l^2

Where l is the length of the square

Area of a square 1 = 4^2

Area of a square = 16 square cm

Area of square 2 = 3^2

Area of square 2 = 9 square cm

Area of square 3 = 2^2

Area of square 3 = 4 square cm

Total area of the square = 16 + 9 + 4

The total area of the square = 29 square cm

Hence, the total square of the figure is 29 square cm

Part B

$\begin{gathered} \text{ To proof if the triangle is a right angled triangle} \\ \text{ We n}eed\text{ to appy Pythagora's theor}em \\ \text{Hypotenus}^2=perpendicular^2+base^2 \\ \text{Hypotenus = 4}cm \\ \text{Perpendicular =3cm} \\ \text{Base = 2cm} \\ 4^2=3^2+2^2 \\ 16\text{ = 9 + 4} \\ 16\text{ }\ne\text{ 13} \\ \text{ Since the hypotenus is not equal to the summation of the perpendicular and base} \\ \text{Hence, the triangle is a not right angled triangle} \end{gathered}$
