Answer:
Step-by-step explanation:
You want to reverse the algebra and solve for y. First you want to subtract the 'a' to both sides.
x - a = -2by^2
Divide by -1 on both sides
-x + a = 2by^2
Divide by 2b on both sides
(-x + a)/2b = y^2
Take the square root of both sides
[tex]\sqrt{(-x+a)/2b}=y[/tex]

A line passes through the points (0, 14) and (18, 15) . What is its equation in slope-intercept form?
Answer:
y= 1/18x + 14
Step-by-step explanation:
Well we can first right the equation like : to find the slope
14- 15
____ = -1/-18 = 1/18
0-18
Now we know the slope is 1/18
we can substitute one point in the equation and the slope to find the equation
let's take 0,14
14= 1/18 ( 0 ) + b
14=b
so b= 14
the y-intercept is 14
the equation is
y= 1/18x + 14
Identify the y-intercept and slope in each graph or table below
Answer:
y - intercept: (0,1) slope: 2
Step-by-step explanation:
The y - intercept is simply where the line touches the y - axis.
In this case, the line touches the y - axis at (0,1)
Our slope can be found out by finding two points on the line and using the formula, or rise over run. Nevertheless, your slope for this line should be 2.

(6x - 6.3) divided by 3
Step-by-step explanation:
We can represent the terms like this:
6x = 3 * 2x6.3 = 3 * 2.1Therefore, (6x - 6.3) / 3
= [(3)(2x) - (3)(2.1)] / 3
= 2x - 2.1.
Answer:
Terms of the equation is :---
6x/3 = 2x and 6.3/3 = 2.1
According to the given problem,
[tex] \frac{(6x - 6.3)}{3} = \frac{3(2x - 2.1)}{3} = \boxed{2x - 2.1} ✓\\ [/tex]

A store selling art supplies finds that they can sell x sketch pads each week at a price of p dollars each, according to the formula x = 1000 − 400 p. What price should they charge (in interval notation and rounded to the nearest cent) if they want to sell
a . At least 625 pads each week? b . More than 300 pads each week?
c . Less than 200 pads each week? d . At most 475 pads each week?
Answer:
c and b and a
Step-by-step explanation:
The store should charge a price between ($0, $0.94] to sell at least 625 pads each week. The store should charge a price between ($0, $1.75) to sell more than 300 pads each week. The store should charge a price between ($2.00, $2.50) to sell less than 200 pads each week. The store should charge a price between [$1.31, $2.50) to sell at most 475 pads each week.
a)
In order to solve part a of the problem, we need to set our equation as an inequality. Part a asks us to find the price the store should charge to sell at least 625 pads each week. The word at least gives us a clue on what symbol to use. In this case we should use the [tex]\leq[/tex] symbol, like this:
[tex]625\leq 1000-400p[/tex]
and now we can solve the inequality, we can start by switching places between the 625 and the 400p so we get:
[tex]400p\leq 1000-625[/tex]
[tex]400p\leq 375[/tex]
and we divide both sides into 400, so we get:
[tex]p\leq \frac{375}{400}[/tex]
[tex]p\leq $0.94[/tex]
So this can be rewritten in interval notation like this:
($0, $0.94] The price they should charge can be located between those two values.
b)
In order to solve part b of the problem, we need to set our equation as an inequality. Part b asks us to find the price the store should charge to sell at more than 300 pads each week. The word more than gives us a clue on what symbol to use. In this case we should use the < symbol, like this:
[tex]300< 1000-400p[/tex]
and now we can solve the equation, we can start by switching places between the 300 and the 400p so we get:
[tex]400p< 1000-300[/tex]
[tex]400p< 700[/tex]
and we divide both sides into 400, so we get:
[tex]p< \frac{700}{400}[/tex]
[tex]p< $1.75[/tex]
So this can be rewritten in interval notation like this:
($0, $1.75) The price they should charge can be located between those two values.
c)
In order to solve part c of the problem, we need to set our equation as an inequality. Part c asks us to find the price the store should charge to sell less than 200 pads each week. The word less than gives us a clue on what symbol to use. In this case we should use the > symbol, like this:
[tex]200> 1000-400p[/tex]
and now we can solve the inequality, we can start by switching places between the 200 and the 400p so we get:
[tex]400p> 1000-200[/tex]
[tex]400p> 800[/tex]
and we divide both sides into 400, so we get:
[tex]p> \frac{800}{400}[/tex]
[tex]p> $2.00[/tex]
at this point we need to know what the maximum price the store can charge is. We can do so by setting the equation equal to zero and solve for p, so we get:
0<1000-400p
so we can now move the 400p to the other side of the equation, so we get:
400p<1000
and divide both sides into 400 so we get:
[tex]p<\frac{1000}{400}[/tex]
which simplifies to:
p<$2.50
if the store charges more than $2.50 they will not sell any item at all.
So this can be rewritten in interval notation like this:
($2.00, $2.50) The price they should charge can be located between those two values to sell less than 200 pads each week.
d)
In order to solve part d of the problem, we need to set our equation as an inequality. Part d asks us to find the price the store should charge to sell at most 475 pads each week. The word at most gives us a clue on what symbol to use. In this case we should use the [tex]\geq[/tex] symbol, like this:
[tex]475\geq 1000-400p[/tex]
and now we can solve the inequality, we can start by switching places between the 475 and the 400p so we get:
[tex]400p\geq 1000-475[/tex]
[tex]400p\geq 525[/tex]
and we divide both sides into 400, so we get:
[tex]p\geq \frac{525}{400}[/tex]
[tex]p\geq $1.31[/tex]
So this can be rewritten in interval notation like this:
[$1.31, $2.50) The price they should charge can be located between those two values to sell 475 pads at most each week.
