Answer:
A bracelet cost $446
Step-by-step explanation:
3 Watch : 3(x + 120)
2 Bracelet : 2x
We have the equation:
3(x + 120) + 2x = 2590
3x + 360 + 2x = 2590
5x + 360 = 2590
5x = 2230
x = 446
For this case we have the following equation:
We want to solve the equation for the letter c.
To do this, we apply the distributive property:
Then, applying addition property of equality we have:
Then applying division property of equality we have:
Answer:
The value of c is:
Answer: x=0
Step-by-step explanation: there isnt an explanation
This graph has its maximum at 4. There is no minimum while the inflection is at 2, 10/3.
<h3>How to solve for the maximum of the graph</h3>
We have ( x-2²) (x-4)
x-2²) = 0, or x - 4
x - 2 = 0, x = 2
Hence we can see that the graph has its minimum at x = 4
b. The graph here does not have a local maximum
<h3>c. Next we have to find the point of inflection</h3>
To do this you have to differentiate the equation
Use the product rule of differentiation in order to solve for the solution.
(x-2)²[ (x-4) 2 (x-2)]
This would then give us
x -2, 3x -10
In both equations we have to make x the subject of the equation
X = 2, x = 10/3
Hence the point of inflection is 2 and 10/3

Answer:
x+3y=14
Step-by-step explanation:
Standard form for an equation of a line is ax+by=c . Some books have restrictions on a,b, and c.
So first thing I'm going to do is state the equation I'm going to use to get there.
I'm going to use the point-slope form because we are given a point (2 really) and we can find the slope using two points (we have).
Line up points and subtract. You will then put second difference over the first difference. This will give you the slope. You could just use (y2-y1)/(x2-x1).
( -1 , 5)
-( 2, 4)
-----------
-3 1
So the slope is 1/-3 or -1/3 .
So the equation in point-slope form, y-y1=m(x-x1), is y-4=-1/3 (x-2) .
y-4=-1/3 (x-2)
First step: I'm going to get rid of the fraction by multiplying both sides by 3.
3y-12=-1(x-2)
Second step: Distribute
3y-12=-x+2
Third step: add x on both sidfes
x+3y-12=2
Fourth step: add 12 on both sides
x+3y=14.
