I think the 3 is an exponent so we can write the expression as
18 * 4y^3
= 72y^3
Answer:
$16.25
Step-by-step explanation:
9.75/3 = 3.25
So therefore 1 bag costs $3.25.
$3.25 × 5 = $16.25

Answer:
y = -0.50x -2.50
Step-by-step explanation:
The perpendicular line will have a slope that is the opposite reciprocal of the slope of the given line:
m = -1/2
The given point can be used with this slope in the point-slope equation for a line:
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y +5 = -1/2(x -5)
y = -1/2x +5/2 -5
y = -0.50x -2.50
Answer:
y=2x-3
Step-by-step explanation:
4x-2y=3
-2y=3-4x
2y=4x-3
y=4x/2-3/2
y=2x-1.5 m1=2 (the number near x)
If the searched line is parallel to the line 4x−2y=3, m1=m2= 2
y=m2x+b - the searched line
1=2*2+b
b=-3
y=2x-3
Answer:
(-6,17)
Step-by-step explanation:
-2x-y=-5,
3x+y=-1
Add the two equations together to eliminate t
-2x-y=-5
3x+y=-1
-------------------
x = -6
Now that we know x, we can substitute it into one equation to find y
3x+y = 1
3(-6) +y = 1
-18 +y = -1
Add 18 to each side
-18+18 +y = -1+18
y = 17
(-6,17)
