Need help.
aev [14]

Answer:

1. y= 3x+7

2.y=1/2 x -1

Step-by-step explanation:

1.

Parallel lines have the same gradient.In the equation given,

y= 3x+5 , the slope is 3

So now, you find the equation of a line passing through point (-1,4) with m=3

m=Δ y/Δx

3= y-4/ x--1

3= y-4 /x+1

3(x+1) = y-4

3x+3 =y-4

3x+3+4=y

⇒⇒ y= 3x+7   is the equation.

2.

Two lines that are perpendicular to each other have the product of their slopes to be -1

Given equation to be y= -2x +8 then, m₁ = -2

Finding m₂ will be;

m₁ *m₂ = -1

-2 * m₂ = -1

-2 m₂ = -1

m₂ = -1/-2 = 1/2

So writing the equation of the perpendicular line with m₂ =1/2 , point (-4,-3)

will be;

m=Δy/Δx

1/2=y--3/x--4

1/2 = y+3/x+4

x+4 = 2( y+3)

x+4 = 2(y+3)

x+4 =2y+6

x+4-6=2y

x-2=2y

x/2 -2/2=y

y=1/2 x -1   is the equation.

If students sit 3 per bench, we are short 3 benches. If they sit 5 per bench,
Ksivusya [100]

An expression is defined as a set of numbers, variables, and mathematical operations. There are a total of 10 benches in the class.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Let the total number of benches be represented by x. If students sit 3 per bench, we are short 3 benches. Therefore, the total number of students can be written as,

Total number of students = 3x + 9

If they sit 5 per bench, 2 benches are left empty, and one bench only has 4 students.

Total number of students = 5(x-1) - 10 +4

Now, the total number of students can be written as,

3x + 9 = 5(x-1) - 10 +4

3x + 9 = 5x - 11

20 = 2x

x = 10

Hence, there are a total of 10 benches in the class.

What is the equation of the line in standard form?
madam [21]

Answer:

x+6y=9 - > y= (-1/6)x+(3/2)

x - 6y=-9 - > y= (1/6)x+(3/2)

-9x - 6y = -9 - > y = (-3/2)x +(3/2)

3x - y = - 6 - > y= 3x + 6

-63x - y = - 6 - > y = - 63x + 6

3x + y = 6 - > y = -3x +6

Step-by-step explanation:

The standard form of the equation of a line is: y=ax+b

You seperate y from x and the constant value(the number) and then devide tge equation with the coefficient of y. Obviously it mustnt be division by zero.
