Write the slope-intercept form equation of a line that goes through the point (4, -4) and is parallel to y = -7x + 5.

Answers

Answer 1

Answer:

y=7x-32

Step-by-step explanation:

Since the line is parallel to y=-7x+5, it will have the same slope

use the slope-intercept form to find b, y=7x+b

plug the points into the equation

(-4)=7(4)+b

simplify

-4=28+b

subtract 28 from both sides

b= -32

plug b into the equation

y=7x-32

What’s the Solutions

Answers

Solve equation [2] for the variable y

[2] y = x + 6

// Plug this in for variable y in equation [1]

[1] (x +6) - 5x = 2
[1] - 4x = -4
// Solve equation [1] for the variable x

[1] 4x = 4

[1] x = 1
// By now we know this much :

y = x+6
x = 1
// Use the x value to solve for y

y = (1)+6 = 7

The cost price of a boat is marked up by 8%.
a. Calculate the cost price if the marked up price is $43200.

Answers

Answer:

$40000

Step-by-step explanation:

The formula is x*1.08 = 43200. If you want to find the original price then isolate x. x*1.08 = 43200 -> x = 40000.

the table below shows the speed of a falling object that every second within the first 5 seconds of its downward motion based on the relationship between speed and time that the same will suggest which equation can be used to find the speed of the object at t seconds A. 8=t/32 B. S=32t C. S=32-t D. s=t+32

Answers

Answer:

B. s = 32t

Step-by-step explanation:

The equation would be in the form of s = mt.

Where, m = rate of change

Find rate of change using any two values given in the table, say (1, 32) and (2, 64)

Rate of change (m) = ∆s/∆m = (64 - 32)/(2 - 1) = 32/1 = 32

✔️To write the equation, substite m = 32 into s = mt

s = 32t

x + 3y = 1
5x +6y = 14

Answers

Answer:

1. X = 1 - 3y

2. -5/6x + 7/3

Those are the answers to the problems

(x,y) = (4,-1)

x + 3y = 1 subtract 5 from both sides you get -5x -15y =-5

now sum it up
-5x -15y =-5
5x +6y = 14
you get -9y = 9
divide both sides by -9

you get y=-1

NOW substitute y for x + 3 times (-1)= 1

solve for x and get x=4

therefore your answer is (4,-1)

The equation of line L is 2x+y=3

Line M is parallel to line L and passes through
(1,−6)

Work out the equation of line M.
Give your answer in the form
y=ax+b

(3 marks)

Answers

Answer:

y = -2x - 4

Step-by-step explanation:

We transform the line equation of L:

2x + y = 3 --(-2x)--> f(x) = y = -2x + 3

We now know that L intersects the y-axis at 3 and it has a slope of -2.

In order to construct a parallel line M, it needs to have an identical slope to L.

All we need to do now is to move one step from the given point (1,-6) towards 0 with the predetermined slope of -2, resulting in the point (0,-4).

Since we know slope and intersection with the y-axis (0,-4), we can construct the line equation:

f(x) = y = -2x - 4 for line M.
