Answer:

The equation of the line is y - 6 = -14/11(x + 4)

Step-by-step explanation:

To find the equation of this line, we first need to find the slope. To do that, we use the slope equation.

m(slope) = (y2 - y1)/(x2 - x1)

m = (6 - -8)/(-4 - 7)

m = (6 + 8)/(-4 - 7)

m = 14/-11

m = -14/11

Now that we have the slope, we can use it and either point in point-slope form and solve for the equation.

y - y1 = m(x - x1)

y - 6 = -14/11(x + 4)

PART A

If 4 pounds = 10 dollars...

4/2 = 2

10/2 = 5

So for 2 pounds, it would cost $5.00

Now for the 1 pound one

4/1 = 4

10/4 = 2.5

For the 1 pound one, it would cost $2.50

PART B

We know that 4 pounds = 10 bucks

Since 1 is 1/10 of 10 (in the cost section), we have to apply this to the pounds section. 4/10 = 0.4. Therefore, $1 = 0.4lb

Now for the last blank...

Since $1 = 0.4, we multiply that by 9. 0.4 x $9 = 3.6lb

The equation of line L is y=5x+1

vovikov84 [41]

Answer:

see explanation

Step-by-step explanation:

Parallel lines have equal slopes.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

L₁ is y = 5x + 1 ← in slope- intercept form

with slope m = 5

L₂ is 2y - 10x + 3 = 0 ( subtract - 10x + 3 from both sides )

2y = 10x - 3 ( divide all terms by 2 )

y = 5x - $\frac{3}{2}$ ← in slope- intercept form

with slope m = 5

Since L₁ and L₂ have equal slopes then they are parallel lines

What is the coefficient of y in the expression 3 ⋅ 4 + 5y?

ZanzabumX [31]

<h3>Answer: 5</h3>

The coefficient is the term just to the left of the variable. So for the term 5y, the number to the left of y is 5.

extra info: 5y is the same as 5*y or "5 times y", where y is a placeholder for some unknown number.

Find the function value f (6) if f(x) = 4x-10

Olenka [21]

So first you plug 6 into the equation which is 4(6)-10.
Using PEMDAS, you solve what’s in the parenthesis first and you get 24-10.
24-10=14
f(6)=14
