X - the number
To decrease the number by 3% you subtract 3% of the number from the number.
The multiplier you would use is
0.97.
Answer:
X = -1, y = 1
( -1 , 1 )
Step-by-step explanation:
You can set them equal to each other since they both equal y
3x + 4 = x + 2
subtract x from both sides to get all the x’s on one sides
2x + 4 = 2
subtract 4 from both sides
2x = -2
divide by 2
x = -1
plug -1 into either equation to get y
-1 + 2 = 1
Answer:
3 1/8 packages of beads
Step-by-step explanation:
We know that Darnell uses 1 1/4 packages of beads to make 10 bracelets. In order to find how many packages of beads he'll need for 25 bracelets, we set up a proportion:
, where x is the number of packages needed
Cross-multiply:
25 * 1 1/4 = 10x
1 1/4 is just 1.25 in decimal form, so:
25 * 1.25 = 10x
31.25 = 10x
x = 3.125 = 3 1/8
So, Darnell will use 3 1/8 packages of beads.

The complete question is
find the slope of the tangent line and the equation of the tangent line at the given point, at the point (3,1).
Answer:
Tangent = 1/23 , equation of tangent = 23y - x = 20
Step-by-step explanation:
We are given the equation
upon differentiation the given function we get
d () /dt
=
upon substituting x=3 ,y=1 we will get
dy/dx = 1/23
now the equation of the tangent will be
y-1 = 1/23 (x-3)
23 (y-1) = x- 3
23y - 23 = x -3
23y - x = 20
