H(x) = x2 + 1 k(x) = x – 2 (h + k)(3)

Elza [17]

Answer:

(h + k)(2) = 5

(h - k)(3) = 9

evaluate 3h(2) + 2k(3) = 17

Do przygotowania ćwierć litra soku potrzebne są 4 marchewki. Ile marchewek potrzeba żeby otrzymać pół litra soku, litr soku, 2li

Alina [70]

Answer:

Part 1) 8 carrots

Part 2) 16 carrots

Part 3) 32 carrots

Part 4) 48 carrots

Step-by-step explanation:

<u><em>The question in English is</em></u>

4 carrots are needed to prepare a quarter liter of juice. How many carrots do you need to get half a liter of juice, a liter of juice, 2 liters of juice, 3 liters of juice

Part 1) How many carrots do you need to get half a liter of juice?

we know that

4 carrots are needed to prepare 1/4 liter of juice

so

using proportion

Find out how many carrots do you need to get 1/2 liter of juice

$\frac{4}{(1/4)}=\frac{x}{(1/2)}\\\\x=4(1/2)/(1/4)\\\\x=8\ carrots$

Part 2) How many carrots do you need to get a liter of juice?

we know that

4 carrots are needed to prepare 1/4 liter of juice

so

using proportion

Find out how many carrots do you need to get 1 liter of juice

$\frac{4}{(1/4)}=\frac{x}{1}\\\\x=4(1)/(1/4)\\\\x=16\ carrots$

Part 3) How many carrots do you need to get 2 liters of juice?

we know that

4 carrots are needed to prepare 1/4 liter of juice

so

using proportion

Find out how many carrots do you need to get 2 liters of juice

$\frac{4}{(1/4)}=\frac{x}{2}\\\\x=4(2)/(1/4)\\\\x=32\ carrots$

Part 4) How many carrots do you need to get 3 liters of juice?

we know that

4 carrots are needed to prepare 1/4 liter of juice

so

using proportion

Find out how many carrots do you need to get 3 liters of juice

$\frac{4}{(1/4)}=\frac{x}{3}\\\\x=4(3)/(1/4)\\\\x=48\ carrots$

Write the equation of the line slope 2, through (3,1)

Arisa [49]

answer:

y = 2x - 5

work:

to write equations, we use the format y = mx + b.

m stands for the slope, and b stands for the y intercept.

this means that you should be able to enter the values for y and x and get a valid equation as a result.

in this equation, we are not given a y intercept value, but we do have a slope and x and y values, so we have to solve by substituting.

so, let's substitute in the values of y and x and the slope,

and solve for b, the y intercept.

1 = 2(3) + b (multiply 2 x 3)

1 = 6 + b (subtract 6 from both sides)

- 5 = b

b has a value of -5. let's place this into the equation.

y = 2x - 5.

the slope is 2, and the y intercept is -5, let's plug in our y and x values to verify that this is true.

1 = 2(3) - 5

1 = 6 - 5

1 = 1

so, this equation is correct. hope this helps and have a great day!

The table represents a function. What is the value of f(–1)?

Afina-wow [57]

Answer : C

we need to the value of f(–1)

Table is given in the question

From the table ,

f(x) = 4 when x= -5, that is f(-5) = 4

f(x) = 0 when x= -1, that is f(-1) =0

f(x)= -1 when x=6, that is f(6) = -1

f(x)= -3 when x=9, that is f(9) = -3

So, the value of f(–1) = 0
