First we need to know both the formula of A and B.
The formula of A is
C = 5 + 0.25p
with C representing total cost and p representing the amount of checks.
The formula of B is
C = 6 + 0.15p
with C representing total cost and p representing the amount of checks.
To find the point where A and B cost the same, we solve the following equation:
5 + 0.25p = 6 + 0.15p
Collecting terms gives us
-1 = -0.1p
Now we have to divide by -0.1 and we get.
10 = p
p = 10
So our answer: after 10 checks both accounts cost the same amount of money. Answer A.
The answer is y = x-4.
<u>Step-by-step explanation</u>:
- The given expression is x-y=4
- Keep y alone on one side and move remaining terms to the other side.
⇒ -y = 4-x
- To have y alone, Multiply the above expression with -ve sign on both sides.
⇒ y = x-4
Answer:
774 lb
Step-by-step explanation:
weight = volume * density
radius = diameter/2
volume = (4/3)πr^3
volume = (4/3)(3.14)(4.7/2 ft)^3
weight = (4/3)(3.14)(4.7/2 ft)^3 * 14.25 lb/ft^3
weight = 774 lb
Answer: 1/(Y^2) or if you want in y^n is y^2
apply exponents law (a^b) ^c = a^b c
take off the parenthesis
1/2 · 4
1 · 4/(2)
4/2
divide it
4/2= 2, nevertheless it become -2
y^-2
1/(y^2)
Hello!
To write this equation, let's first find the slope using the formula

.
Plug in the values

Now solve to find our slope.

<u />Your slope is -3.
Plug that into slope-intercept equation.

Now we find our y-intercept by plugging in a y-coordinate for the y value in the equation. I'll use 6

Your y-intercept is -2.
Your equation is y = -3x - 2
