Answer:
I'm pretty sure it's B. compression but I'm not 100% sure not to good at that
A. The (x,y) coordinates where the equations y =4x and y = 2x - 1 intersect on a graph is the solution to that system of equations. When solving for this system of equations by substitution of y, the equation 4x = 2x -1 is obtained. So the x-coordinate obtained is both a solution to the equation 4x = 2x - 1 and the intersection point of the system of equations y = 4x and y = 2x - 1.
B. Idk about this part... Says to make a tables to solve for 4x = 2x - 1.
If you make a table for Eq. #1. y = 4x and Eq. #2. y = 2x -1 maybe..
#1. y = 4x
x ...... y
-4 .. -16
-3 .. -12
-2 .. -8
-1 .. -4
0 ... 0
1 ... 4
2 .... 8
3 ... 12
4 ... 16
the solution to 4x = 2x - 1 ; the x-coordinate is not an integer value so Idk what the point of this is.....
4x = 2x - 1
4x - 2x = -1
2x = -1
x = -1/2
not an integer..
C. You can solve the equation 4x = 2x - 1 graphically by graphing y = 4x and y = 2x - 1 and identifying the x-coordinate at the point of intersection.
Answer:
50 gallons of red
30 gallons of blue
Step-by-step explanation:
5 parts of the whole must be red, 3 parts of the whole must be blue, and there are 5+3=8 parts in total.
therefore, 1 part = 80/8 = 10 gallons
red : 5 parts
5×10 = 50 gallons
blue : 3 parts
3×10 = 30 gallons

Answer:
See below!
Step-by-step explanation:
1. 5g + h = g
4g = -h
g = ![-\frac{h}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7Bh%7D%7B4%7D)
2. y = mx + b
y - b = mx
m = ![\frac{y - b}{x}](https://tex.z-dn.net/?f=%5Cfrac%7By%20-%20b%7D%7Bx%7D)
3. 3y + z = am - 4y
7y = am - z
y = ![\frac{am - z}{7}](https://tex.z-dn.net/?f=%5Cfrac%7Bam%20-%20z%7D%7B7%7D)
4. km + 5x = 6y
km = 6y - 5x
m = ![\frac{6y - 5x}{k}](https://tex.z-dn.net/?f=%5Cfrac%7B6y%20-%205x%7D%7Bk%7D)
5. ![\frac{3ax - n}{5} = -4](https://tex.z-dn.net/?f=%5Cfrac%7B3ax%20-%20n%7D%7B5%7D%20%3D%20-4)
3ax - n = -20
3ax = n - 20
x = ![\frac{n-20}{3a}](https://tex.z-dn.net/?f=%5Cfrac%7Bn-20%7D%7B3a%7D)
6. ![\frac{by+2}{3}= c](https://tex.z-dn.net/?f=%5Cfrac%7Bby%2B2%7D%7B3%7D%3D%20c)
by + 2 = 3c
by = 3c - 2
y = ![\frac{3c-2}{b}](https://tex.z-dn.net/?f=%5Cfrac%7B3c-2%7D%7Bb%7D)
7. at + b = ar - c
at - ar = -b - c
a(t - r) = -(b + c)
a = ![-\frac{b+c}{t-r}](https://tex.z-dn.net/?f=-%5Cfrac%7Bb%2Bc%7D%7Bt-r%7D)
