Answer:

es 3

Step-by-step explanation:

Para encontrar el mcd de 9 y 57:

Los factores de 9 son 9, 3, 1.

Los factores de 57 son 57, 19, 3, 1.

Los factores en común de 9 y 57 son 3, 1, los cuales intersectan los dos conjuntos arriba.

En la intersección de los factores de 9 ∩ factores de 57 el elemento mayor es 3.

Por lo tanto, el máximo común divisor de 9 y 57 es 3.

Answer:

3

Step-by-step explanation:

9's multiples are 1, 3, and 9. 57's multiples are 1, 3, 19, and 57. The greatest common factor is 3 since that is the highest factor they share.

Answer: The cat's weight is 4.33 pounds

• The dog's weight is 17.32 pounds.

Step-by-step explanation:

Let the weight of the cat be represented by a.

Devi’s dog weighs 4 times as much as her cat. This can be written as:

= 4 × a

= 4a

Her dog also weighs 13 pounds more than the cat. This can be written as:

= a + 13

We then equate both equations. This will be:

4a = a + 13

4a - a = 13

3a = 13

a = 13/3

a = 4.33 pounds

The cats weight is 4.33 pounds

Since the dog's weight = 4a = 4 × 4.33 = 17.32 pounds

Given:

The measure of the first angle is 40° less than the measure of the second.

To find:

The measures of the complementary angles that satisfy the given condition.

Solution:

Let the measure of first angle be x°.

According to the given condition,

First angle = Second angle - 40°

[tex]x^\circ =\text{Second angle}-40^\circ [/tex]

Add 40° on both sides.

[tex](x+40)^\circ =\text{Second angle}[/tex]

We know that, sum of complementary angles is 90°. So,

First angle + Second angle = 90°

[tex]x^\circ +(x+40)^\circ =90^\circ [/tex]

[tex]2x^\circ +40^\circ =90^\circ [/tex]

[tex]2x^\circ =90^\circ -40^\circ [/tex]

[tex]2x^\circ =50^\circ [/tex]

Divide both sides by 2.

[tex]x^\circ =25^\circ [/tex]

So, the measure of first angle is 25°.

[tex](x+40)^\circ =(25+40)^\circ =65^\circ[/tex]

So, the measure of second angle is 65°.

Answer:

He does not divide the numerator and the denominator by the same number. Nicholas divides 20 by 5 and 30 by 6. He ought to have divided 30 by 5 as well and then simplified.

P.S. Nicholas should have just divided both 20 and 30 by 10 to simplify in one step

Answer:

The slope is 2/3

Step-by-step explanation:

you need to use the equation y=rise over run, so the equation would be 2-4 over -2-1 and that would equal 2/3 and to graph you just need to find the y-intercept and put it together with the slope y=2/3+b

Answer:

y =  -2

Step-by-step explanation:

To find the answer, use property of inequality:

10-5y=20
Undo the +10, so - 10 to the other side
so,
-5y= 10, or -5xY.

so divide by -5 from both sides:

10/-5=-2
so, the remain of the equation is:
y = -2
which is the answer

The solution of   [tex]\rm log(2t+4)=log(14-3t)[/tex]  is t=2

It is given that:

[tex]\rm log(2t+4)=log(14-3t)[/tex]

It is required to find the value of 't'.

It is another way to represent the power of numbers ie.

[tex]a^b=c\\log_ac=b[/tex]

We have:

[tex]\rm log(2t+4)=log(14-3t)[/tex]   [tex]\rm (Taking \ log_1_0 \ base \ and \ removing \ the \ log_1_0 \ from \ both \ the\ side)[/tex]

We will get:

[tex]\rm 2t+4=14-3t\\\rm 5t=10\\\rm t=2[/tex]

Therefore the solution of   [tex]\rm log(2t+4)=log(14-3t)[/tex]  is t=2

f(x) = 2 ( x² + 8x ) - 7

     = 2 [(x + 4)² - 4²] - 7

     = 2 (x + 4)² - 32 - 7

(x+4)² = x² + 2*x*4 + 4² = x² + 8x + 4²

it's why

x² + 8x = (x + 4)² - 4²

2 software packages + 5 months of gameplay = $130

$40 + 5 months of gameplay = $130

5 months of gameplay = $90

1 month of gameplay = $18

Answer:

18 dollars

Step-by-step explanation:

m = months of game play

130 = (20 + 1m) + (20 + 4m)

130 = 40 + 5m

90 = 5m

18 = m

Answer:

[tex]y=-\frac{3}{2}+2[/tex]

Step-by-step explanation:

First subtract 6 from both sides:

[tex]6x+4y=8[/tex]

-6            -6

New equation becomes:

[tex]4y-6=8[/tex]

Divide all by 4:

4     -6      8

---    ---      ---

4       4       4

[tex]y=-\frac{3}{2}+2[/tex]

Hence, the final answer is [tex]y=-\frac{3}{2}+2[/tex]

Step-by-step explanation:

If you combine the you just need to add them using the amount under weekly 584+987.19= 1571.19 weekly

Simple interest formula:

Total = start value x (1 + (rate x time))

Total = 13000 x 1.282

Total = £16,666

Answer:  see below

Step-by-step explanation:

#5 - 7: Domain are the x-values and Range are the y-values.

5) Coordinates are: (-2, 3), (0, 3), (2, 3), (4, 3)

   Domain: x = {3}         Range: y = {-2, 0, 2, 4}

6) All points on the curve between -4 and 2 (x-values) & 3 and 6 (y-values). Endpoints are included.

Domain: -4 ≤ x ≤ 2         Range: 3 ≤ y ≤ 6

7) All points on the curve between 2 and 7 (x-values) & 1 and 6 (y-values). Endpoints are not included.

Domain: 2 < x < 7         Range: 1 < y < 6

#8 - 11: Choose points for x. Plug them into the equation to solve for y.

To graph the equation, plot the points and connect the dots.

8)                  x         y = x

                   -2             -2

                    -1             -1

                     0             0

                     1              1

                     2             2

9)                  x         y = 2x+1

                   -2             2(-2)+1 = -3

                    -1             2(-1)+1 =  -1

                     0            2(-0)+1 =  1

                     1             2(1)+1 =   3

                     2            2(2)+1 =  5
