What do you need if you have to write the equation of a parabola?
This straight line outside the parabola is called the directrix. For parabolas that open either up or down, the standard form equation is (x - h)^2 = 4p(y - k). For parabolas that open sideways, the standard form equation is (y - k)^2 = 4p(x - h). The vertex or tip of our parabola is given by the point (h, k).

Solve the equation. Identify any extraneous solutions.
h = sqrt 3h
-3 is a solution of the original equation. 0 is an extraneous solution.
0 and 3 are solutions of the original equation.
3 is a solution of the original equation. 0 is an extraneous solution.
0 is a solution of the original equation. 3 is an extraneous solution.
Answer:
It's the second option:
0 and 3 are both solutions.
Step-by-step explanation:
h = √(3h) Square both sides:
h^2 = 3h
h^2 - 3h = 0
h(h - 3) = 0
h = 0, 3.
If we plug h = 0 into the original equation:
0 = √(3*0) = 0 so this is a root.
x = 3:
3 = √(3*3) = 3 so this is also a root.
Answer:0 and 3 are solutions of the original equation.
Step-by-step explanation:
What is the Y-intercept and The slope of the equation?
2x+7y=14
Can someone please help me with this!!!
Slope choice:
A. 2/7
B. 7/2
C. -2/7
D. -9
Y-intercept choices
A. 2
B. 7
C. -2
D. 0
Answer:
Slope = -2/7; Y intercept = +2
Step-by-step explanation:
First, for this particular question - we want to convert the equation to slope intercept form! You may recognize it already, it looks like this:
y = mx + b
Here's how:
[tex]2x+7y=14\\2x+7y - 2x = -2x+14\\7y=-2x+14\\\frac{7y}{7} =\frac{-2x+14}{7} \\y = \frac{-2}{7}x+2[/tex]
The above shows this equation in slope intercept form: y = -2/7x + 2.
The slope of this line is -2/7 while the y intercept is 2!
*Note*: In the slope-intercept formula, m stands for the slope, and the b is the intercept!
Hope I was of assistance! Algebra can be a little difficult but you'll get it! Have a nice day and spread the love! <3

A box of crayons costs $1.75, including tax. Mr. Valentino wants to purchase boxes of crayons for his class and has a $25 budget. Write an inequality to solve for the number of boxes of crayons Mr. Valentino can purchase.
NEED HELP PLZZZ :( WILL GIVE BRAINIEST IF RIGHT
A $1.75x ≤ $25
B $1.75x ≥ $25
C $25x ≤ $1.75
D $25x ≥ $1.75
Answer:
A ) $1.75 x ≤ $25
Step-by-step explanation:
the cost of x boxes of crayons = 1.75x dollars
If there is a budget of only $ 25,
So, the cost of x boxes of crayons ≤ $25
Answer:
Since his budget is 25, it's less than or equal to ( ≤ 25). That means your answer would be A $1.75x ≤ $25 because 1.75 times the amount of crayons can't go over the $25 budget.

Kelly inherits land which had a basis to the decedent of $95,000 and a fair market value of $50,000 on August 4, 2018, the date of the decedent’s death. The executor distributes the land to Kelly on November 12, 2018, at which time the fair market value is $49,000. The fair market value on February 4, 2019, is $45,000. In filing the estate tax return, the executor elects the alternate valuation date. Kelly sells the land on June 10, 2019, for $48,000. What is herrecognized gain or loss? ($1,000) ($2,000) ($47,000) $1,000 None of the above
Answer:
The correct option is;
Her recognized loss is ($1,000)
Step-by-step explanation:
The given information are;
The basis of the land to the decedent = $95,000
The land's market value on 4th of August 2018 when the decedent died = $50,000
The alternate valuation date = 6 months + The date of death of the decedent = 4th February, 2019
The value filed by the executor on the tax return using the alternate valuation date = The market value of the estate on 4th of February 2019
The market value of the land on 4th of February 2019 = $45,000
∴ The value filed by the executor on the tax return using the alternate valuation date = $45,000
The value of the land on November 12, 2018 when the executor distributed the land to Kelly = $49,000
The value at which Kelly sells the land on June 10, 2019 = $48,000
Given that, recognized gain is the profit made from selling an asset based on the value of the asset when it was obtained, we have;
Kelly's recognized gain or loss = (The value at which Kelly sells the land) - (The value of the land when the executor distributed the land to Kelly)
Kelly's recognized gain or loss = $48,000 - $49,000 = -$1,000 = ($1,000)
Therefore, Kelly's recognized loss = ($1,000).

you are a contractor installing a brick sidewalk. The portion of the sidewalk will occupancy and area of 100 feet long by 4 feet wide. Each brick will occupy and area 8 inches long by 4 inches wide what is the minimyn nuber of bricks will you need to occupy this area
Answer:
1800 bricks
Step-by-step explanation:
Given
Sidewalk = 100ft by 4ft
Brick = 8 inches by 4 inches
Required
Determine the minimum number of bricks
First, we need to determine the area of both;
[tex]Sidewalk = 100ft * 4ft[/tex]
[tex]Sidewalk = 400ft^2[/tex]
[tex]Brick = 8in * 4in[/tex]
[tex]Brick = 32in^2[/tex]
Number of bricks is calculated as follows;
[tex]Number = \frac{Sidewalk}{Brick}[/tex]
[tex]Number = \frac{400ft^2}{32in^2}[/tex]
Convert ft^2 to in^2
[tex]Number = \frac{400 * 144in^2}{32in^2}[/tex]
[tex]Number = \frac{57600in^2}{32in^2}[/tex]
[tex]Number = 1800[/tex]
Complete the sentence about the relation. There is x and y columns. The x column contains two, eight, thirty, and forty six values. The y column contains minus one, nine, and sixteen values. The first arrow starting from value two of column x and ended at the value minus one in column y. The second arrow started from value eight of column x and ended at sixteen in column y. The third arrow starting from value thirty of column x and ended at value nine in column y. The forth arrow starting from point forty six and ended at value sixteen in column y. The domain of the relation is Choose... and the range is Choose... .
Answer:
Domain is [tex]\{2,8,30,46\}[/tex]
Range is [tex]\{-1,9,16\}[/tex]
Step-by-step explanation:
The relation refers to the collection of ordered pairs, which contains an element from one set to another set.
Domain of a relation [tex]y=f(x)[/tex] is all the values [tex]x[/tex] that go into a function, and the range is a set of all the values [tex]f(x)[/tex] that are obtained for the given domain.
The given relation is [tex]\{(2,-1),(8,16),(30,9),(46,16)\}[/tex]
Here, domain is [tex]\{2,8,30,46\}[/tex]
Range is [tex]\{-1,9,16\}[/tex]

An animal shelter has $2500 in its reserve fund. The shelter charges $40 per animal placement and would like to have at least $4000 in its reserve fund. Write an inequality to represent this situation.
Answer:
if you search the Question up the fist thing to pop up should say Gr7_Math_Revision_T2. on the 7th page your answer, I think. is there
Step-by-step explanation:
Step 1
Write and solve the inequality:
2,500 + 40a ≥ 4,000, or 40a ≥ 1,500
a ≥ 37.5
Step 2
If the shelter places 30 cats and 10 dogs,
or 40 animals, that will be enough to meet
its goal, because a = 40 is a solution to the
inequality a ≥ 37.5.
