6x – 3y = 8

Nat2105 [25]

Answer:

Step-by-step explanation:

The linear equation where:

$\large \boldsymbol {} \sf y=\underbrace{m}_{slope }x \ +\underbrace{b} _{y -intersept}$

Solution :

$\displaystyle \sf \#13. \\\\ 6x-3y=8 \\\\\ -3y=8-6x \\\\y=-\frac{8-6x}{3} \\\\ \boxed{\sf y=2x-2\frac{1}{3} }} \\\\ slope =2 \\\\ y-intersept =-2\frac{1}{3} \\\\-------------$

$\sf \#14 . \\\\\\ 7x=5y+2 \\\\5y=7x-2 \\\\y =\dfrac{7x-2}{5} \\\\ \boxed{\sf y=1,4x-0,4} \\\\slope = 1,4 \\\\y-intersept =-0,4 \\\\---------------$

$\dispalystye \sf \#15. \\\\ -6y+4x=8 \ |\div2 \\\\-3y+2x=4 \\\\ y=-\dfrac{4-2x}{3} \\\\ y=\boxed{\sf \frac{2x-4}{3} } \\\\slope = \dfrac{2}{3} \\\\ y-intersept = -\dfrac{4}{3 }\\\\ -----------------$

$\sf \#16 .\\\\ x+y=2x+3 \\\\y=2x-x+3 \\\\\boxed{\sf y=1\cdot x+3} \\\\slope =1 \\\\y-intersept =3$

4) If the area of a square is 48cm², What is the length of each side? Simplify your answer.

Talja [164]

Answer:

4 sqrt(3) cm

Step-by-step explanation:

The area of a square is

A = s^2 where s is the side length

48 = s^2

Take the square root of each side

sqrt(48) = sqrt(s)

sqrt(16*3) = s

4 sqrt(3) =s

Kitty [74]

Answer:

A dot plot is similar to histogram wherein they show the frequency of data. In this kind of plot, instead of bars, dots are stacked on their corresponding bin. The bins here are the number of pets, while the dots are the students. So, the 2 dots above number 3 signifies that, there are two students with three pets. The answer is A.

A triangle has side lengths of (2t + 2) centimeters, (6t – 7) centimeters,

Scorpion4ik [409]

A triangle is a three-sided polygon. The sum of angles in a triangle is 180 degrees.

Types of triangles

An equilateral triangle : the three sides are equal in length.
An isosceles triangle : two sides are equal in length
A right angled triangle : an angle measures 90 degrees

The perimeter of a triangle is (8t -7 + u) centimeters

The perimeter of a triangle is the sum of the three lengths of the triangle

2t +2 + 6t - 7 + u -2

Combine similar terms

(2t + 6t) + (2 - 7 - 2) + u

Add combined similar terms

8t -7 + u
