Answer:

Part A: One.

Part B: (3, 5)

Step-by-step explanation:

Part A: A solution to a pair of equations is generally where the two functions intersect. As we can see, a graph is provided, so things are facilitated. We can see that they only intersect once, which means only one answer.

Part B: The solution, which as we have learned is where the two lines intersect, is (3, 5), as that is, again, the point of intersection.

Answer:

For f(x) = √(2·x + 2) - √(x + 18), at f(x) = -1 the possible x-values includes;

-0.757, -17.5

Step-by-step explanation:

Given that the function is f(x) = √(2·x + 2) - √(x + 18)

The value of 'x' when f(x) = -1, is given as follows;

-1 = √(2·x + 2) - √(x + 18)

-1² = (√(2·x + 2) - √(x + 18))² = 3·x + 20 - 2·√(2·x + 2)×√(x + 18)

1 = 3·x + 20 - 2·√(2·x + 2)×√(x + 18)

2·√(2·x + 2)×√(x + 18) = 3·x + 20 - 1 = 3·x + 19

2·x² + 38·x + 36 = (3·x + 19)/2

2·x² + 38·x + 36 - (3·x + 19)/2 = 0

4·x² + 73·x + 53 = 0

From which we get;

x = (-73 ± √(73² - 4 × 4 × 53))/(2 × 4)

x ≈ -0.757, and x ≈ -17.5

Answer:

x = 3.

Step-by-step explanation:

(∛44x - 7) - 5 = 0

Cube the expression.

44x - 7 - 125 = 0

Subtract.

44x - 132 = 0

Add 132 to both sides.

44x = 132

Divide by 44.

x = 3.

Proof:

(∛44x - 7) - 5 = 0

(∛44(3) - 7) - 5 = 0

(∛132 - 7) - 5 = 0

(∛125) - 5 = 0

5 - 5 = 0

0 = 0

Answer:

-2

Step-by-step explanation:

To find the slope of a line with 2 given points, you use the formula

m=y2-y1/x2-x1

Now you plug in the points which would be m=3-(-1)/2-4 which equals m=4/-2

4/-2 equals -2

The slope is -2

Answer:

A Lucia le sobró dinero y la cantidad que sobró es: 488 pesos.

Step-by-step explanation:

Para determinar si le faltó o le sobro dinero, debes determinar el costo total de lo que compró multiplicando el precio de cada artículo por la cantidad comprada y sumando estos valores:

(60*12)+(156*7)+(350*2)=720+1092+700=2512

Dado que pagó con 3000 pesos y el costo total de lo que compró es de 2512 pesos y este valor es menor que 3000 en 488 pesos, la respuesta es que le sobró dinero.

Answer: 4.9 ft

Step-by-step explanation:

Given

Length of wire [tex]l=7\ ft[/tex]

Stake is at a distance of [tex]5\ ft[/tex] from the base of tree

suppose wire is attached y ft  above the base of tree

from the figure, we can write

Answer:

201.1

Step-by-step explanation:

πx8²=201.1

One way to find the midpoint is to start at either endpoint (A or B), and count how many spaces it takes to get to the other endpoint. You should count exactly 5 spaces. This means that the midpoint will have us travel 5/2 = 2.5 spaces when we start at either endpoint and walk to the other side.

If we start at point A and move 2.5 units up, then we'll arrive at (-2, 1.5)

If you start at point B (where the red x is) and move 2.5 units down, you'll get to (-2, 1.5)

The midpoint is located at (-2, 1.5)

------------------------------------------

Another method is to use the coordinates of A and B. Point A is located at (-2, -1) and point B is located at (-2, 4)

Focus on the x coordinates for now only. The x coordinates are -2 and -2, so they are the same in this case. Adding them up leads to -2+(-2) = -4. Then we divide by 2 to get -4/2 = -2. It turns out that if the coordinates are the same, then adding them up and dividing by two leads to the same coordinate value.

Now move onto the y coordinates. Points A and B have y coordinates of -1 and 4 respectively. They add to -1+4 = 3 and that cuts in half to 3/2 = 1.5

The results of -2 and 1.5 we got in the previous two paragraphs then immediately lead to the midpoint's exact location of (-2, 1.5)

Answer:

-1/8

Answer:

negative 1/8 or 0.125

Step-by-step

-1/2 cancells out the plus, so it is just 3/8 - 4/8 = -1/8

Answer:

x = number of cards that cost $2.50 each = 5

y = number of cards that cost $3.25 each = 1

Step-by-step explanation:

The equations are:

x + y = 6 (1)

2.5x + 3.25y = 15.75 (2)

From (1)

x = 6 - y

Substitute x = 6 - y into (2)

2.5x + 3.25y = 15.75 (2)

2.5(6 - y) + 3.25y = 15.75

15 - 2.5y + 3.25y = 15.75

- 2.5y + 3.25y = 15.75 - 15

0.75y = 0.75

y = 0.75/075

y = 1

Substitute y = 1 into (1)

x + y = 6

x + 1 = 6

x = 6 - 1

x = 5

Therefore,

x = number of cards that cost $2.50 each = 5

y = number of cards that cost $3.25 each = 1

The roles and relationships that exist amongst the producers, consumers, and decomposers in an ecosystem is described by the food chain.

The meaning of ecosystem is the complex of a community of organisms and its environment functioning as an ecological unit.

Producer is an organism that produces its own food e.g. photosynthesis in plants. Also known as the base of the food-chain.

Consumer is an organism that consumes (eats) either a producer or another consumer e.g. animals will solely eat plants (herbivore), solely animals (carnivore), or a combination of both (omnivore).

Studies are showing that most animals are omnivores. Even pre-concluded herbivores or carnivores are found to eat a small variety of both plants and animals in a pinch. E.g. a deer would eat a baby bird if it found it on the ground.

Decomposers are organisms that 'eat' and break up dying/decaying material e.g. earthworms and fungi.

All of this together is the food cycle.
