Answer:

Step-by-step explanation:

1 Solve:

8r + 4 = 10 + 2r

We will collect the variable terms on the left hand side of the equation and constants on the right hand side of the equation

8r - 2r = 10-4

6r = 6

r= 6/6 = 1

2 Solve:

-2(x + 3) = 4x - 3

-2x -6 = 4x - 3

We will collect the variable terms on the left hand side of the equation and constants on the right hand side of the equation

-2x - 4x = -3 + 6

-6x = 3

x = 3/-6

x = -1/2

3 Solve

5 + 3(q - 4) = 2(q + 1)

5 + 3q - 12= 2q+2

We will collect the variable terms on the left hand side of the equation and constants on the right hand side of the equation

3q - 2q = 2 +12 - 5

q = 9

4. Solve

7x - 4 = -2x + 1 + 9x - 5

We will collect the variable terms on the left hand side of the equation and constants on the right hand side of the equation

7x +2x-9x = 1 - 5 +4

0= 0

5 Solve:

8x + 6 - 9x = 2 - x -15

We will collect the variable terms on the left hand side of the equation and constants on the right hand side of the equation

8x -9x + x = 2 - 15 -6

0x = -19

0= 19

Function f is shown on the graph below where two points are marked. If function f is horizontally compressed by a factor of 2, p
lilavasa [31]

Answer:

If you have    

f(x) = x^2

The point  (2,4)   would be transformed to (1,1)

Step-by-step explanation:

If your compression is horizontal then the transformation you are making is the following

g(x)  = f(x/2)

Therefore, if you have    

f(x) = x^2

The point  (2,4)   would be transformed to (1,1)

Heyy!!
rosijanka [135]

<u>Answer:</u>

6^{10}

<u>Step-by-step explanation:</u>

We can use the following rule of surds to solve the problem:

\boxed{a^m \times a^n = a^{m + n}},

which means that when multiplying two numbers with the same bases, we can simply add their powers while keeping the base the same.

Applying this rule:

6^2 \times 6^8

⇒ 6^{2 + 8}

⇒ \bf 6^{10}

CINDY made costume decorations. She used 1/10 of a meter of ribbon for each decoration which she got by cutting 3/10 of a meter
Brilliant_brown [7]

Answer:

Cindy made 3 decorations with the ribbons

Step-by-step explanation:

Since Cindy used 1/10 of a metre of ribbon to make just one decoration that she obtained by dividing 3/10 of a meter of ribbon into equal parts, then we can calculate the number of decorations that Cindy made. In this scenario, all we need is an idea on how to divide fractions and we are good to go.

If Cindy used 1/10 of a metre obtained by dividing 3/10 of a metre of ribbon to make decorations, then the number of decorations she made can be gotten by dividing 3/10 by 1/10

i.e 3/10 ÷ 1/10

= 3/10 × 10/1

= 3 decorations.

That is she used 1/10 + 1/10 + 1/10 = 3/10 to make (3 decorations).
