Step-by-step explanation:

B

4(3x+2y)

12x + 8y

E

6x+6x+4y+4y

12x + 8y

F

5x+3x+3x+x+6y+y+y

5x+6x+x+6y+2y

12x+8y

Step-by-step explanation:

(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)

(y + 7)/(-4 + 7) = (x + 8)/(-4 + 8)

(y + 7)/3 = (x + 8)/4

4(y + 7) = 3(x + 8)

4y + 28 = 3x + 24

4y = 3x + 24 - 28

4y = 3x - 4

y = 3x/4 - 1

Answer:

Jorge's weight change was approximately 5%.

Marie's weight change was approximately 14%

Marie had the greater percent change.

Step-by-step explanation:

Solution:

Marie's former weight = 175

New weight = 150

Difference = 175 - 150 = 25

Percentage change = 25/175 × 100

= 1/7 × 100

= 14.2%

Jorge's former weight = 190

Jorge's new weight = 180

Difference = 190 - 180 = 10

Percentage change = 10/190 × 100

= 5.26%

From the above explanation, the following are right:

• Jorge's weight change was approximately 5%.

• Marie's weight change was approximately 14%

• Marie had the greater percent change.

Answer:

Step-by-step explanation:

Jorge’s weight change was approximately 5%.

Marie’s weight change was approximately 14%.

Marie had the greatest percent change.

Marie: 175-150 = 25

What percentage is 25 of 175 = x/100 = 25/175

= 14.29%

Jorge: 190-180= 10

What percent is 10 of 190? = x/100 = 10/190

= 5.3%

Answer:

solution 1: 5

solution 2: -4

Step-by-step explanation:

x²-x-20=0;

(x-5)(x+4)=0;

x₁=5; x₂=-4.

Answer:

Solution 1: [tex]x = 5[/tex]

Solution 2: [tex]x = -4[/tex]

Step-by-step explanation:

The first is organize the given equation to the next form

[tex]ax^2 + bx + c[/tex]

So you substract -20 in both sides of the equation

[tex]x^2 - x - 20 = 0[/tex]

Know you can use the quadratic formula or find two number that sum give us [tex]b[/tex] and multiplied [tex]c[/tex].

[tex]b = s + r\\c = sr[/tex]

Replacing with the given values we have:

[tex]-1 = s + r\\-20 = sr[/tex]

With a trial and error the numbers are -5 and 4. Then you change the equation to

[tex]x^2 - x - 20 = (x - 5)(x + 4)[/tex]

And the equation is equal to 0 when  [tex]x[/tex] is equal to 5 and -4.

Answer:

even

Step-by-step explanation:

the last digit is an even number

Hey there!

• Odd numbers are numbers that cannot be divided evenly

- EXAMPLE: 1, 3, 5, 7, & etc.

• Even numbers are numbers that can be divided evenly by 2

- EXAMPLE: 2, 4, 6, 8, & etc.

But that Without further ado lets answer the question

96 ÷ 2 = 48

96 is divisible of 2

So therefore, “96” is an EVEN NUMBER

Good luck on your assignment and enjoy your day!

Step-by-step explanation:

perpendicular to the x-axis means it is parallel to the y-axis.

and that means it is simply just a constant x value.

which x value ?

well, the point defines it (2).

Answer:

$131250

Step-by-step explanation:

Talia's earnings during one year are equal to her base yearly salary ($65000) added to her commission. Now, to know the commission it is necessary to find the 2.65% of her total sales ($2.5 million)

Step 1. Divide the total sales or 2,500,000 by 100 considering this represents the total or 100%

2,500,000 ÷ 100 = 25000

Step 2. Multiply this number by the specific percentage (2.65)

25000 x 2.65 = 66250

Now add the commission and the yearly salary

65000 + 66250 = 131250

Hence, total earnings of Talia were $131250

Step-by-step explanation:

I am not sure that you typed it all correctly.

but based on what is written here

f(x) = x²

g(x) = sqrt(x) + 2

so, g(f(2)) + f(1) = g(2²) + 1² = g(4) + 1 = sqrt(4) + 2 + 1 =

= 2 + 2 + 1 = 5

Answer:

  a) 56 shells in each jar

  b) 297 shells were picked

  c) 2, 8, 14, 20, ... shells were discovered (=2+6n); 47, 48, 49, 50, ... shells in each jar (=47+n); for n=0, 1, 2, 3, ...

Step-by-step explanation:

The first digit is given as 5. The second is 9 less than 3 times 5, so is

  3×5 -9 = 15 -9 = 6

The 2-digit number that is Sally's house address is 56.

Sally originally planned to put 56 shells in each jar.

__

If each of the 5 jars has 56 shells, and Sally collected 17 more than that, she originally picked ...

  5×56 +17 = 280 +17 = 297

Sally originally picked 297 shells.

__

We saw that the number of shells to go into jars is 280. That will fill 6 jars with ...

  280/6 = 46 4/6 . . . . shells in each jar

That is, Sally can fill 6 jars with 46 shells each, and have 4 shells left over. The number of additional shells to put the same number in each jar will be a number that makes a multiple of 6 when 4 is added to it. Already we know that adding 2 shells will bring the total to 6 "extra", so will allow 1 more shell to be added to each of the 6 jars.

  additional shells = 2 +6n . . . . . . for some whole number n

  number in each jar = 47 +n . . . . . for the same whole number n

Sally could have discovered, 2, 8, 14, ... shells in her pocket.

Answer:

Step-by-step explanation:

right triangle a² + b² = c²

                      9² + b² = 13²

                      81 + b² = 169

                            b² = 169 - 81

                            b² =  80

                            b  =[tex]\sqrt{80}[/tex]

   [tex]V = \frac{1}{3} \pi r^2h[/tex]

   [tex]V = \frac{1}{3} \pi (\sqrt{80} )^2 (9)[/tex]

  [tex]V = 3\pi (80)[/tex]

   [tex]V = 240\pi[/tex]

    Using π = 3.14                      Using calculator value of π

      V = 753.6                                V  =  753.9822369
