Answer:
The range of the equation is y ≥ 9 ⇒ C
Step-by-step explanation:
The quadratic equation y = ax² + bx + c, represents by a parabola of vertex (h, k), where h = [tex]\frac{-b}{2a}[/tex] and k is the value of y at x = h
The range of the quadratic if it has a minimum vertex is y ≥ k, and y ≤ k if it has a maximum vertexThe parabola has a minimum vertex if the value of a is positive and a maximum vertex if the value of a is negative∵ The equation is y = x² + 9
→ Compare it with the form above to find a and b
∴ a = 1 and b = 0
∵ a is a positive number
∴ The parabola has a minimum vertex
→ By using the 1st rule above
∴ The range is y ≥ k
→ Use the rule of h above to find it
∵ h = [tex]\frac{-(0)}{2(1)}[/tex] = [tex]\frac{0}{2}[/tex]
∴ h = 0
→ To find k substitute x by the value of h and y by k
∵ k = (0)² + 9
∴ k = 0 + 9
∴ k = 9
∴ The range of the equation is y ≥ 9

You cross multiply 5 and 5 and 2 and 6 to create a new fraction
Answer:
12/25
Step-by-step explanation:
so what you would do is keep the first fraction (2/5) then change the symbol then flip the last fraction (5/6). so then you would multiply 2*6= 12 and 5*5=25. so the answer would be 12/25.

help me please
Answer:
difference = 3, first term = 4
Step-by-step explanation:
given, a2 = 7
a9 = 28
wkt, a2 = a + d = 7
a9 = a + 8d = 28
- 7d = - 21
therefore d = 3
and wkt, d = a2 - a
a = 7 - 3 = 4

Help I need help this is a question I don’t understand
Answer:
Triangle ADB is an isosceles triangle that has been split in half. Isosceles triangles are triangles whose base angles are equal and has 2 equal side lengths. For example triangle ADB has AD and DB equal along with m<a and m<b equal
Therefore, if we split this triangle into two half's then they are congruent (the same)
Right triangles have a 90° angle, usually marked by a square
this means that m<DCA is 90°;AD=DB=14m; CB=AC=11; AB=AC+CB=22

Your thrteater company sells tickets to their holiday showing off the nutcracker. Tickets cost $5 each. Tickets for adults cost $8 each. The total sales on opening night is $720. Write an equation to show the total sales as a combanation of kid tickets and adult tickets sold.
Answer:
5x + 8y = 720
Step-by-step explanation:
Let the :
Number of kid tickets sold = x
Number of adult tickets sold = y
Hence:
Tickets for kids cost $5 each.
Tickets for adults cost $8 each.
The total sales on opening night is $720.
The equation to show the total sales as a combanation of kid tickets and adult tickets sold is:
$5 × x + $8 × y = $720
5x + 8y = 720
Therefore, the equation to show the total sales as a combanation of kid tickets and adult tickets sold is
5x + 8y = 720
Which of these best describes the location of (9,0) on a coordinate grid? Question 12 options: In Quadrant I In Quadrant II On the x-axis On the y-axis
Help quick!
Step-by-step explanation:
Quadrant I: Both values are positive.
Quadrant II: x-value is -ve, y-value is +ve.
On the x-axis: y-value is 0.
On the y-axis: x-value is 0.
The point (9, 0) has a y-value of 0.
=> It lies on the x-axis.
When plotting points on the coordinate plane below, which point would lie on the x-axis?
Answer:
If you plot the points you can easily find the answer. (X,Y) The x-axis is the horizontal line and the y-axis is the vertical line.

ken eats 4 plums each day. How many plums would he eat in TWO weeks?
Answer:
56 (plums)
Step-by-step explanation:
There's 7 days a week, 14 in two weeks, so if Ken eats 4 plums each day, he will eat 14 times that in two weeks.
x = 4 × 14
x = 56
Answer:
56
Step-by-step explanation:
4 plums a day, with 7 days in a week. 4*7=28 plums a week. He eats 4 plums a day for two weeks, so we multiply 28 by 2. 28*2=56.

What are the zeros of the function (x) = x2 – 3x+2?
Step-by-step explanation:
f(x) = x² - 3x + 2 = (x - 2)(x - 1).
When f(x) = 0, (x - 2)(x - 1) = 0.
=> x = 2 or x = 1.
Explain the similarities and differences in the steps used to solve the equation and inequality.

Composition of functions~
Answer:
option D
Step-by-step explanation:
First you must find g(n) given that n is -3n:
g(-3n) = -3n - 1
Then plug that in f(n) as the new n:
f(n) 3( -3n - 1) + 5
= -9n -3 + 5
= -9n + 2
So option D

–5x + 4 – x –1 a. terms: -5x, 4, -x, -1; like terms: -5x, -x; 4, -1; coefficients: -5, -1; constants: -1 b. terms: -5x, 4, -x; like terms: -5x, -x; 4, -1; coefficients: -5, -1; constants: 4, -1 c. terms: -5x, 4, -x, -1; like terms: -5x, -x; 4, -1; coefficients: -5, -1; constants: 4, -1 d. terms: -5x, 4, -x, -1; like terms: -5x, -x; 4, -1; coefficients: 4, -1; constants: -5, -1
Given:
The expression is
[tex]-5x+4-x-1[/tex]
To find:
The terms, like terms, coefficients and constants.
Solution:
We have,
[tex]-5x+4-x-1[/tex]
It can be written as
[tex]=(-5x)+4+(-x)+(-1)[/tex]
So, terms are [tex]-5x,4,-x,-1[/tex].
It two terms have same variable of same degree, then they are called like terms.
[tex]-5x,-x[/tex] are likes terms because degree of variable is 1 and 4, -1 are like terms because degree of variable is 0.
In the product of a number and a variable, the number is called coefficient.
Variable terms are [tex]-5x,-x[/tex]. So, coefficients are -5 and -1.
Constant terms are free from variable. So, constant terms are 4 and -1.
Terms: [tex]-5x,4,-x,-1[/tex];
Like terms: [tex]-5x, -x;4, -1[/tex];
Coefficients: -5, -1;
Constants: 4, -1
Therefore, the correct option is c.
1. If the point (-5, -3) is translated 4 units to the right and 3 units down, what are the coordinates
of the new point? Write the algebraic expression that represents the translation.
Answer:
(-5 + 4, -3 - 3)
Step-by-step explanation:
"4 units to the right" requires ADDING 4 to the x-coordinate of (-5, -3):
(-5 + 4, -3).
"3 units down" requires SUBTRACTING 3 from the y-coordinate:
(-5 + 4, -3 - 3), or (if simplified) (-1, -6)
The equation of the line graphed below could be which of the following?
Please help ASAP
Answer:
4.
Step-by-step explanation:
First, you have to decide whether the slope is negative or positive. Since the line is going diagonally upward, it is positive.
That means the answer has to be either 3 or 4.
Next, you have to decide whether the y-intercept is negative or positive, on the graph, you can see that it is positive.
Answer choice 4 is the only equation where both the slope and the y-intercept are positive, so it is the answer.
Isaac invested $77,000 in an account paying an interest rate of 4.6% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest cent, would be in the account after 12 years?

The amount of the money to the nearest cent, would be in the account after 12 years is $133,307.18.
Calculation of the amount:Since the invested amount is $77,000
The rate of interest is 4.6% compounded continuously
And, the number of years is 12
So,
= $77,000 * (1 + 0.046/12)^48
= $133,307.18
hence, The amount of the money to the nearest cent, would be in the account after 12 years is $133,307.18.
