Vertex is (-3,0)
Axis of symmetry=x=-3There is only one x intercepts
Only one real root is -3Answer:
vertex = (-3, 0)
axis of symmetry: x = -3
one real root at x = -3
Step-by-step explanation:
The vertex is the turning point of the curve (so the maximum point for parabolas that open downwards, and the minimum point for parabolas that open upwards)
The axis of symmetry is the vertical line that goes through the vertex of a parabola. So this will be the line of the x-value of the vertex.
The roots of a parabola are the points where the curve intersects (or touches) the x-axis.
First graph
vertex = (3, -4)
axis of symmetry: x = 3
roots: x = 1, 5
Second graph
vertex = (-3, 0)
axis of symmetry: x = -3
one real root at x = -3
A rental car company charges $42.72 per day to rent a car and $0.10 for every mile driven. Zoey wants to rent a car, knowing that:
She plans to drive 200 miles.
She has at most $350 to spend.
Which inequality can be used to determine xx, the maximum number of days Zoey can afford to rent for while staying within her budget?
Answer:
7 Days
Step-by-step explanation:
Miles cost:
$0.10 * 200 = $20
Daily Cost
Her budget at this point is $330 because $350 - $20 (the miles)
$330 / 42.72 = Roughly 7.72
Therefore Zoey can drive for 7 days before her budget runs out.

You divide two polynomials and obtain the result 5x2−13x+47−102x+2. What is the dividend?
Answer:
5x2−115x+49
Step-by-step explanation:
hope it helps
5x²-115x+49 is the required dividend.
What is dividend?A dividend is a number that is being divided, if 2x is a dividend and 2 is a divisor, then it gives remainder 2, when 2x is divided by 2.
The given polynomial is,
5x²-13x+47-102x+2
To find dividend, simplify this polynomial,

write an equation of a line passing through the point (-4,11) and perpendicular to the line 4x + 5y = -45
Answer:
y = 5/4x - 6
Step-by-step explanation:
First, put 4x + 5y= -45 in y = mx + b form
4x + 5y= -45
5y = -4x - 45
y = -4/5x - 9
So, the slope is -4/5. Perpendicular lines have a opposite reciprocal slope, so the line's slope will be 5/4 right so to find the equation of the perpendicular line in this question, plug in the slope and given point into y = mx + b, and solve for b
y = mx + b
-11 = 5/4(-4) + b
-11 = -5 + b
-6 = b
so you should Plug in b and the slope into y = mx + b
y = 5/4x - 6
So, the equation is y = 5/4x - 6

A couch and coffee table cost a total of $996. The cost of the couch is two times the cost of the coffee table. Find the cost of each item.
Answer: the cost of the couch is 664 and the cost of the coffe table is 332
Step-by-step explanation:
X is the cost of the coffee table and 2x is the cost of the couch (which is two times more than the coffee table)
2x + x = $996
3x = $996
x = 996/ 3
x = $332 (this is what the coffee table cost)
2x => 2(332)
2x => $664 (the cost of the couch which is two times the cost of the coffee table)
together, $332 + $664 = $996 total
A box has 3 one-dollar bills, 2 five-dollar bills, 2 ten-dollar bills, and 1 twenty-dollar bill. A student selects one bill from the box at random.
PART A Develop a probability model to compare the probability of selecting $5 to the probability of selecting $10. Explain.
PART B how does the probability of selecting $1 compare to the probability of selecting $20? explain
Answer and explanation:
There's 3 one dollar bills
2 five dollar bills
and 2 ten dollar bills
and 1 twenty dollar bill
3+2+2+1=8
Part A: The probability of selecting 5 is 2/8 and the probability of selecting 10 is also 2/8 and both of them are the same, 1/4.
Part B: The probability of selecting a one dollar bill is 3/8 and the probability of selecting a twenty dollar bill is 1/8 because there are 3 one dollar bills in 8 bills and 1 twenty one dollar bill in 8 bills only.
WILL GIVE BRAINLIEST The mass of a substance, which follows a continuous exponential growth model, is being studied in a lab. A sample increases continuously at a relative rate of 7% per day. Find the mass of the sample after four days if there were 123 grams of the substance present at the beginning of the study.
Do not round any intermediate computations, and round your answer to the nearest tenth.
Then we know that we originally had 38 grams of the substance, the rate of growth is 18%, and that the time it was allowed to grow is 6 days. Then we have using the exponential growth model that the amount of the sample after 6 days will be S = P e^rt where P is the initial sample amount, r is the rate of growth, t is the time, and S is the final sample amount. S = 38 e^ .18*6 = 38 e ^ 1.08 = 111.8978 Thus if there were 38 grams of the substance present at the beginning of the study the mass of the sample would be 111.8978 grams after the study.

Simplify the expression. 2y−5(y−3)=
Answer:
-3y -15
Step-by-step explanation:
2y - 5(y-3) = 2y -5y - 15
= -3y -15
Your welcome, and feel free to comment if you need have any questions!
The simplified value of the expression, 2y−5(y−3) using the Distributive property is 15- 3y.
Given Expression:
2y−5(y−3)
Using Distributive property
[tex]{\text} a *(b+c) = (a *b) + (a*c)[/tex]
So, applying the Distributive property in the expression 5(y - 3) gives
5(y - 3) = 5y - 15
Substituting the value 5y - 15 in 2y−5(y−3) as
2y−5(y−3) = 2y - (5y-15)
= 2y - 5y + 15
Now, operating the simplified value is
2y−5(y−3) = 15 - 3y
Thus, the simplified expression is -3y + 15.

What is the exact area of the following circle?
Answer:
56.25 pi cm^2
Step-by-step explanation:
To find the area of the circle,
we use the formula
A = pi r^2, where r is the radius
We know the diameter is 15 so we can find the radius from
r = d/2 where d is the diameter
r = 15/2
A = pi ( 15/2) ^2
A = pi ( 225/4)
A = 56.25 pi cm^2
Answer:
2nd option
› 56.25π cm²
Step-by-step explanation:
we know ,
area of circle is πr²
so,
given,
diameter,d = 15cm
radius,r = d/2 = 15/2 = 7.5 cm
so,
area = πr²
= (7.5×7.5)π
= 56.25π cm²
