Answer:
To get an expression relating to x you need to have x alone on one side of your equation. ie x =
Try this:
rx - st = r
remove st from the rx side
rx = r + st
now divide by r
x = (r + st)/r
You now have your expression relating to x

A cube has an edge of 3 feet. The edge is increasing at the rate of 4 feet per minute. Express the volume
of the cube as a function of m, the number of minutes elapsed.
Hint: Remember that the volume of a cube is the cube (third power) of the length of a side.
Answer:
so it increases by 4 per minute
the volume of a cube is v=side^3
so the side length be 5+4m where m is the number of minutes
therefor the volume can be expressed as V(m)=(5+4m)³
Step-by-step explanation:
The volume of the cube can be expressed as a function of m, the number of minutes elapsed as V(m) = (3 + 4m)³ feet³.
What do we mean by volume?The volume of an object is the total space occupied by the object in the three-dimensional space.
How do we solve the given question?In the question, we are asked to express the volume of a cube as a function of m, the number of minutes elapsed. We are given that the initial length of the edge of the cube was 3 feet, and it increases at a rate of 4 feet per minute.
∴ We can say that the length of the edge after m minutes = 3 + 4m
As 4 feet is the increase per minute and m minutes have elapsed.
We know, that the volume of a cube is the cube of the length of the edge.
∴ The volume = (3 + 4m)³.
Hence, the function of the volume of the cube in m can be written as,
V(m) = (3 + 4m)³ feet³.

Answer:
8 2/3
Step-by-step explanation:
Y=a|x-h|+k
11. how does the value of k affect the graph?
12. how does the value of h affect the graph?
13. how do the sign and absolute value of A affect the graph?
Step-by-step explanation:
Given the general form of the absolute value function, y = a|x - h| + k
11. How does the value of k affect the graph?The value of k determines how far up or down the parent function is translated. If k is positive, the function is translated k units up. If k is negative, the function is translated |k | units down.
12. How does the value of h affect the graph?The value of h determines how far left or right the parent function is translated. If h is positive, the function is translated h units to the right. If h is negative, the function is translated |h | units to the left.
13. How do the sign and absolute value of A affect the graph?The value of a determines whether the graph opens up or down.
If a is positive, the graph opens up.If a is negative, the graph opens down.The value of a also makes the parent function wider or narrower.
If 0 < a < 1, the graph is wider than the parent function.If a > 1, the graph is narrower than the parent function.Just pls give an answer ._.||

One side of a triangle is X another is X+3 and the third is 2X-1. If the perimeter is 66 inches what is the length of each piece
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
Perimeter of a triangle is equal to the sum of measures of its three sides, that is :
[tex]x + x + 3 + 2x - 1 = 66[/tex][tex]4x + 2 = 66[/tex][tex]4x = 64[/tex][tex]x = 16[/tex]so, the three sides are :

Line w is parallel to line v and passes through point (–6, 10). Which is the equation of line w in slope-intercept form?
A: y= 3/4x+2
B: y=-3/4x+2
C: y=-4/3x+2
Answer:
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes.
Parallel lines have identical slopes
As our original line has a slope of 3/4, both lines v and w have slope of -4/3
This means that
C: y = -4/3x + 2
is the only possible option.
Let's check that the given point fits on this line.
10 = -4/3(-6) + 2
10 = 10
So our answer is correct.
