1/6 Book

GalinKa [24]

Given:

$\frac{1}{6} \text{ book in } \frac{2}{3} \text{ hours}$

To find:

Number of books per hour

Solution:

We have to calculate the book read in one hour.

$\frac{1}{6}\text{ book }\rightarrow\frac{2}{3}\text{ hour}\\\\\text{we have to multiply both the side with 2/3}\\\\\frac{1}{6}\times\frac{3}{2}\text{ book }\rightarrow\frac{2}{3}\times\frac{3}{2}\text{ hour}\Rightarrow\frac{1}{4}\text{ book }\rightarrow1\text{ hour}$

Therefore, we can conclude that the answer is $\bold{\frac{1}{4}\text{ book }\rightarrow1\text{ hour }}$ which is option B.

Distributive property Use the distributive property to remove the parentheses .{y+10}12=

malfutka [58]

Answer:

12y + 120

Step-by-step explanation:

First of, what is the distributive property?

The distributive property is the property that helps distribute numbers under the parenthesis.

For example, lets use {x+1}4. You distribute the 4 towards the x and the one like this:

4(x) + 1(4)

4x + 4

Now, let's go back to your problem

Solution:

{y+10}12

12(y) +12(10)

= 12y + 120

Hope this helps! Make sure to give me the brainliest answer since it would be greatly appreciated! Thank You!

I need help on solving this math problem.

son4ous [18]

Answer:

f(1)=-3

f(-4)=-11

f(6)=0

Step-by-step explanation:

Use the correct formula depending on what (x) equals.

When (x=1) you use the second formula because 1 is greater than -2 but less than 4

When (x=-4) you use the first formula because -4 is less than -2

When (x=6) you use the third formula because 6 is greater than 4

Help asap! Thanks in advance! There's two questions btw:)

lutik1710 [3]

Answer:

[1].

Option A and D are correct.

[2].

Option A is correct

Step-by-step explanation:

[1].

Quadratic function states that it is an equation of second degree i.,e it contains at least one term that is squared.

The standard form of the quadratic equation is; $ax^2+bx+c = 0$

A.

$y(y+4)-y = 6$

Using distributive property: $a\cdot (b+c) = a\cdot b + a\cdot c$

$y^2+4y-y=6$

Combine like terms;

$y^2+3y = 6$

or

$y^2+3y -6=0$ which represents a quadratic equation.

B.

$3a-7 = 2(7a-3)$

$3a-7 = 14a-6$

or

$11a+1 = 0$ which is not a quadratic equation.

C.

(3x+2)+(6x-1) = 0

Combine like terms;

9x +1 = 0 which is not a quadratic equation.

D.

4b(b) = 0

$4b^2 = 0$ which represents the quadratic equation.

[2].

Given the parent function: $y=x^2$

The reflection rule over x axis is given by;

$(x, y) \rightarrow (x, -y)$

then

the function become: $y = -x^2$

Vertical shift:

If c is a positive real number, the graph y=f(x)+c is the graph of y =f(x) shifted upward c units.

If c is a positive real number, the graph y=f(x)-c is the graph of y =f(x) shifted downward c units.

then;

The graph $y=-x^2-3$ is the graph of $y=-x^2$ shifted 3 units down.

Therefore, the translation of the graph of $y=x^2$ to obtain $y=-x^2-3$ is, reflect over the x-axis and shift down 3

Complete the following conversions. i) 1 m2 = a cm2 ii) 1 cm2 = b mm2 iii) 1 km2 = c m2

Fofino [41]

The values that complete the conversions are

a = 10000

b = 100

c = 1000000

<h3>Conversion of units </h3>

From the question, we are to complete the given conversions

i)

1 m² = a cm²

NOTE: 1 m² = 10000 cm²

∴ a = 10000

ii)

1 cm² = b mm²

NOTE: 1 cm² = 100 mm²

∴ b = 100

iii)

1 km² = c m²

NOTE: 1 km² = 1000000 m²

∴ c = 1000000

Hence, the values that complete the conversions are

a = 10000

b = 100

c = 1000000
