Answer:x + 3y = 5
3y = -x + 5
y = -(1/3)x + 5/3
slope = -1/3 Parallel lines have the same slope.
Now, you have a point and a slope, so use the Point-Slope form of the equation of a line.
y - y1 = m(x - x1)
y - 4 = (-1/3)(x + 2)
y - 4 = (-1/3)x - 2/3
y = (-1/3)x + 3 1/3 Slope-intercept Form
(1/3)x + y = 10/3 Multiply both sides by 3.
x + 3y = 10 Standard form
Hope this helps and don't yell at me in the comments if I am wrong
plz mark me brainliest if I am correct
Answer:
<h2>
y = 16/25x³</h2>
Step-by-step explanation:
If y is inversely proportional to a^3, this is expressed as;
y∝1/a³
y = k/a³ where k is the proportionality constant
Given a=2, y=10, then 10 = k/2³
k = 10*2³
k = 80
Substituting k = 80 back into the formula;
y = 80/a³ ............. 1
Similarly, if a is directly proportional to x, then a ∝ x i.e a = kx
If x=4, a=20 then;
20 = 4k
k = 20/4
k = 5
Substituting k = 5 back into the formula;
a = 5x ....... 2
Substitute equation 2 into 1;
y = 80/a³
y = 80/(5x)³
y = 80/125x³
y = 16/25x³
<em>Hence the formula for y in terms of x is y = 16/25x³</em>

Answer:
D and yes
Step-by-step explanation:
+ 1 = -3 If we multiply both sides of the equation by 4 will will get the second equation
(4) + (4) 1 = (4) -3
x + 4 = -12 We solve this for x by subtracting 4 from both sides.
x = -16
Plug -7 into both equations and you will see that it is a solution
+ 1 = -3
+ 1 = -3
-4 + 1 = -3
-3 = -3
x + 4 = =12
-16 + 4 = -12
-12 - -12
Step-by-step explanationdomain and range of 1/(4-9x) is second one.
The first (and most typical) way to find distance of two points is by using the distance formula.
One alternative is the Manhattan metric, also called the taxicab metric. This option is much more complicated, and rarely used in high school math. d(x,y)=∑i|xi-yi|
