Which of the following is not a quadratic equation * x²+ 4x 11 X² X² 4x 5x² 90 2x X² X² 5?

Answers

Answer 1

A quadratic equation is an equation of the form ax² + bx + c = 0, where a, b, and c are real numbers and a ≠ 0. So , x + 4x 11 cannot be solved as a quadratic equation.

A quadratic equation is an equation of the form ax² + bx + c = 0, where a, b, and c are real numbers and a ≠ 0. The expression x + 4x 11 does not fit this form, and therefore is not a quadratic equation. In the equation, x is an unknown variable, and 4x 11 is a linear expression. Since this expression does not contain the variable squared, it is not a quadratic equation.

x + 4x 11 cannot be solved as a quadratic equation.

The measure of central angle LOP is °. The length of LP is units. The length of MP is units.

Answers

Answer:

2.87units

Step-by-step explanation:

Find the diagram attached

The length of MP can be gotten using the pythagoras theorem

LP² = LM² + MP²

8.5² = 8² + MP²

72.25 = 64 + MP²

MP² = 72.25 - 64

MP² = 8.25

MP = √8.25

MP = 2.87units

Hence the length of MP is 2.87units

The measure of central angle LOP is 180°. The length of LP = 17 units. The length of MP = 15 units.

What is Pythagoras's theorem?

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

The given is given in the question, as shown.

As per the question, we can see that

The measure of central angle LOP is 180°.

LM = 8 units

LP = 2OP

LP = 2(8.5)

LP = 17 units

So the length of LP = 17 units.

As we know that the Pythagorean Theorem,

LP² = LM² + MP²

17² = 8² + MP²

289 = 64 + MP²

MP² = 289 - 64

MP² = 225

MP = 15 units

Thus, the length of MP = 15 units.

PT=y,TR=x+3,QT=2y,TS=3x-1 I'm confused and u really need help. My teacher isn't the greatest and wasn't much help.

Answers

Answer:

y=10, x=7

Step-by-step explanation:

Since the diagonals of a parallelogram bisect each other, PT should be equal to TR and QT should be equal to TS. So, y=x+3 and 2y=3x-1. Multiplying the first equation by 3 gives you 3y=3x+9. Using elimination to subtract these two equations gives you y=10. And since y=x+3, substitute y=10 there. 10=x+3, x=7.

Respuesta:

Alfredo = 59 pegatinas

Ivan = 23 pegatinas

Explicación paso a paso:

Dejar :

Pegatinas de Alfred = a

Pegatinas de Ivan = b

a = b + 36 - - - (1)

a + 10 = 3b- - - (11)

De 1)

a = b + 36

Ponga a = b + 36 en (11)

b + 36 + 10 = 3b

b + 46 = 3b

46 = 3b - b

46 = 2b

b = 23

a = b + 36

a = 23 + 36

a = 59

Alfredo = 59 pegatinas

Ivan = 23 pegatinas

Parker needs to buy bouquets for table centerpieces. Her client has a budget of $250. If the bouquets cost $14.95 each, which direct variation equation can you use to determine the number of flower bouquets Parker can purchase?
A. x=14.95y
B. y=250x
C.250=14.95x
D. y=250(14.95)

Answers

Answer:

C

Step-by-step explanation:

as stated by the questions, the client has a budget of $250, which means we can't exceed $250. This will be our y (dependent variable, as the cost for y depends on how many bouquets we will purchase).

the bouquets cost 14.95 each, so if we have x bouquets , that means that the cost will be 14.95x (independent variable, as this gives the value of y).

therefore, the equation is 250=14.95x, which is C

but let's do process of eliminiation to double check:

if we look at the options, B and D are out (the cost of the bouquets isn't $250 each and also we can't have 250 bouquets , that would be too expensive for the client).

that leaves A and C

A isn't the correct answer. At first glance, it looks like we just switched x and y around. However, it cannot work because x is always the independent variable while y is the dependent variable (the value of y depends on the value of x, while the value of x doesn't depend on y).

Also, there's no mention of the $250 budget in A

by process of elimination and by the explanation above C is the correct answer.

The value of the machinery after 5 years is $236.20

Step-by-step explanation:

Generally, we have the depreciation exponential expression as;

V(t) = I (1 - r)^t

V(t) is the value of the machinery at a point in time

I is the initial value or the cost of the machinery when bought which is $400

r is the rate of decrease which is 10% and is same as 10/100 = 0.1

t is the time which is 5 years

Substituting these values;

V(5) = 400( 1 - 0.1)^5

V(5) = 236.196

to the nearest vent, this is $236.20

Roxanne set a goal o drinking 2.5 liters of water each day.By 10:00 a.M., she drank 3/4 liter, and at lunch she had another 600 ml. In the afternoon. She purchased a ottle of water of water that contained 1.1 liters

Answers

Answer:

She has to drink 0.05 liters more

Step-by-step explanation:

She has to drink 2.5 liters of water each day.

The total amount of water she  drank  is

3/4 liters + 0.6 liters + 1.1 liters + x liters = 2.5 liters

0.75 liters + 0.6 liters + 1.1 liters + x liters = 2.5 liters

2.45 liters + x liters = 2.5 liters

x liters = 2.5 liters - 2.45 liters

x liters = 0.05 liters

She has to drink 0.05 liters more  or has not drunk 0.05 liters.

If she drinks 0.05 liters more she will reach her set goal.

3/4 liters

1 liter= 1000ml

3/4 liters= 3* 1000/4 ml

3/4 liters= 3000/4 ml

3/4 liters= 750  ml

750 ml/ 1000ml = 0.75 liters

On Sunday, they traveled one-third of the remaining distance.

Suppose the total distance is x

Distance traveled on Saturday is  [tex]\dfrac{5x}{8}[/tex]

Remaining distance is

[tex]x-\dfrac{5x}{8}=\dfrac{3x}{8}[/tex]

On Sunday, they travel
