y=-3x-4 is your answer because the line is parrell

We can rearrange 3x+y=9 to look more conventional by subtracting 3x from both sides and making it y= -3x+9.

Now we want to find a line that is parallel to this and goes through the point (0,-4). We know that -3 is the slope. With this in mind, if we want the other line to be parallel then it must have the same slope so that they never intersect. This gives us one of the numbers we need for the second line.

This means our second equation is looking like; y= -3x+b. This means we need to find b (the y-intercept) but we are also given a point it must go through and this is (0,-4). We simply plug this in into our new equation we need to solve and we get ; -4 = -3(0) + b . "since 0 is the x and -4 is the y" . From this we get that b= -4. This means the equation of a line parallel is:

y = -3x-4

If you have a vertical angle and the side angles are 83 and 83 whats the other one?

Hoochie [10]

Answer:

97°

Step-by-step explanation:

you do $83*2=166$ and then $360-166=194$ which is the total sum of the two unknown vertical angles. once you have that, divide it by 2 to get $194/2=97°$ as the measure of each individual unknow vertical angle

A hockey player strikes a hockey puck. The height of the puck increases until it reaches a maximum height of 3 feet, 55 feet awa

MariettaO [177]

Answer:

The maximum height of the second pluck is greater than that of the first pluck, hence the second pluck travels further

Also the distance of the maximum height of first pluck from the player is less than the distance of the second pluck from the player hence the second pluck travels further

Step-by-step explanation:

From the question we are told that

The maximum height of the first pluck is $h_1 = 3 \ ft$

The height of the second height is mathematically represented as

$$y=x\left(0.15-0.001x\right)$

=> $y=0.15x -0.001x^2$

Generally at maximum height $y' = 0$

$y'=0.15 -0.002 x = 0$

=> $x = 75 \ ft$

Here 75 ft is the horizontal distance the second pluck traveled at maximum height

So the maximum height of the second pluck is mathematically represented as

$y=0.15(75) -0.001(75)^2$

=> $y= 5.625 \ ft$

So comparing the maximum height of the first and the second pluck we see that the maximum height of the second pluck is greater than that of the first pluck, hence the second pluck travels father

Could anyone please help me find k divided by 9 = 12 as well as 84n = 504 and 6 = m over 148? I need explanations...

Lana71 [14]

k / 9 = 12
Multiply each side of the equation by 9 : k = 108

84 n = 504
Divide each side of the equation by 84 : n = 6

6 = m / 148
Multiply each side of the equation by 148 : 888 = m
