The vertex, zeros, and y-intercept for the given quadratic equation f(x)=       -x² - 4x+5 are respectively,

Vertex- (2, 1)

Zeros-  (2 + i)

Y-intercept- 5

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

For example, 3x+2y=0.

Types of equation

1. Linear Equation

2. Quadratic Equation

3. Cubic Equation

Given that,

f(x) = y =  -x² - 4x+5

y = -x² - 4x+5

For making it perfect square, we can add and subtract square value of half of coefficient of x

So,  adding and subtracting +4 and -4 in the given equation

y = -x² - 4x+5+4-4

  = -x² - 4x+4+5-4

  = (-x +2)² +1

y-1 = (-x +2)²

So, for vertex

-x +2 = 0

x = 2

y-1 = 0

y = 1

For Zeros, y = 0

y-1 = (-x +2)²

(-x +2)² = -1

x = 2 + i,   -2-i

the zeros are imaginary

For y intercept, x = 0

y-1 = (-x +2)²

y   = 1 + (2)²

y   = 5

Hence,  vertex, zeros, and y-int. are respectively (2, 1), (2 + i), 5

Answer:

Step-by-step explanation:

You want to know the numbers of calories in a cheeseburger and an order of fries if 4 cheeseburgers and 3 fry orders have 4100 calories, and 5 cheeseburgers and 6 fry orders have 6250 calories.

If we let c and f represent the calories in a cheeseburger and an order of fries, respectively, then we can describe the calories in the two orders by ...

Subtracting the second equation from twice the first gives ...

  2(4c +3f) -(5c +6f) = 2(4100) -(6250)

  3c = 1950 . . . . . . . simplify

  c = 650 . . . . . . . divide by 3

Then the calories in the fries can be found by substituting in the first equation:

  4(650) +3f = 4100

  3f = 1500 . . . . . . . . . subtract 2600

  f = 500 . . . . . . . . divide by 3

There are 650 calories in one cheeseburger, and 500 calories in one order of fries.

__

Additional comment

The attachment shows solution of these equations using the matrix functions of a graphing calculator. It reduces the augmented matrix of coefficients of the equations to a form that makes the variable values apparent.

The method of solution shown above uses the "elimination" technique to eliminate the 'f' variable from the equations. We noticed that the coefficient of 'f' in the second equation was double that in the first equation, so subtracting 2 times the first from the second makes the 'f' coefficient zero. We chose that subtraction so the 'c' coefficient would end up positive.

Answer: cheeseburger: 650 calories     fries: 500 calories

Answer:

Tomo can make more one whole batch of brownies. Tomo can make exactly four batch(es) of brownies with the sugar he has.

Based on the information provided, we can logically deduce the following parameters:

Number of cups of sugar is equal to 4/3 cups of sugar.

Number of cups of sugar to make one whole batch of brownies is equal to 1/3 cup of sugar.

In order to determine the exact batches of brownies which Tomo can make based on the number of cups of sugar he has, we would divide the  number of cups of sugar by the number of cups of sugar that is required to make one whole batch of brownies as follows;

Batch of brownies = 4/3 ÷ 1/3

Batch of brownies = 4/3 × 3

Batch of brownies = 12/3

Batch of brownies = 4 batches of brownies.

A discounted surfing lesson costs $50, and a discounted parasailing trip costs $80.

Let x represent the discounted cost per person for a surfing class.

Let y represent the reduced cost per person for surfing instruction.

The cost of taking a surfing lesson and going parasailing is $130

x + y = 130--------------(i)

25 people take

Surfing lessons and 30 people go parasailing and a total of $3,650 is collected

25x + 30y = 3650--------------(ii)

We solve for y using equ (i):

y = 130 - x ------------(iii)

Substitute equ (iii) to equ (ii) and solve for x

25x + 30(130 - x) = 3650

25x + 390 - 30x = 3650

-5x = -250

-x = 50

We solve for y using equ (iii):

y = 130 - x

y = 130 - 50

y = 80

The solution of the equation 8x + 3y = 5 and 3x + 2y = 5 is x = -5/7 and y = -7/24

In math the term called equation is defined as a mathematical statement that shows that two mathematical expressions are equal

Here we have given that the equation 8x + 3y = 5 and 3x + 2y = 5 and we need to solve the equation to find the values of x and y.

in order to solve the equation we have to multiply 2 with the equation (1), then we get,

=> 16x + 6y = 10

And then we have to multiply 3 with the equation (2), then we get,

=> 9x + 6y = 15

Now, we have to subtract these two equation then we get,

=> 7x = -5

=> x = -5/7

Then the value of y is calculated as,

=> 8(-5/7) + 3y = 5

=> -40/7 + 3y = 5

=> 3y = -35/40

=> 3y = -7/8

=> y = -7/24

Therefore, the solution is found.

The circumcenter of the triangle is at the point (22, 36). This is the point where the three thin strips of wood cross and where Mike attached the kite's string.

The point of concurrency of the lines perpendicular to the sides of a triangle is known as the circumcenter of the triangle. To find the circumcenter of a triangle with vertices at (x1, y1), (x2, y2), and (x3, y3), you can use the following formula:

x = (x1 + x2 + x3) / 3

y = (y1 + y2 + y3) / 3

Plugging in the coordinates of the three vertices, we get:

x = (0 + 44 + 0) / 3 = 22

y = (58 + 36 + 0) / 3 = 36

The probability that both cards are sevens is 0.0044
What is probability?

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

There are 52 cards, 4  are sevens.  

So the probability of picking the first 7 is 4/52.  

If you don't replace the card, then there are only 51 cards left, 3 of which are sevens.

So the probability of picking a seven on the second draw is 3/51.

Vertex form of parabola is y = a(x-h)^2 + k

where (h,k) is the location of the vertex.

Here, h= -1 and k = -4
