Answer:

Step-by-step explanation:

Distribute:

2n-12-15=-6n+18-1

Combine like terms:

2n-27=-6n+17

Put -27 on other side and -6n on other side:

8n=44

Divide:

n=5.5

a.) y= 0.2x + 9 and y= 0.5x

b.) 30 emails

c.) the first plan

Step-by-step explanation:

a.) cost per email is a variable

b.) graph and find intersection of the lines

c.) plug in 500 for x in both equations

The number of email messages where both plans will cost the same will be 300 messages.

The system of equations to model the cost of the two internet plans based on the information given will be:

Internet provider 1 = 9 + 0.02m

Internet provider 2 = 0.05m

where m = number of mails

The number of email messages where both plans will cost the same will be:

9 + 0.02m = 0.05m

Collect like terms

0.05m - 0.02m = 9

0.03m = 9

m = 9/0.03

m = 300

When there's 500 messages for the month, the cost for each plan will be:

Internet provider 1 = 9 + 0.02m

= 9 + 0.02(500)

= 9 + 10

= 19

Internet provider 2 = 0.05m

= 0.05(500)

= 25

Therefore, based on the calculation, the first plan is cheaper.

Answer:

BAC = 58, CAD = 32

Step-by-step explanation:

The angle of BAD is 90 degrees, this is represented by the red outline of a square. This means that adding angles BAC and CAD will equal 90.

15x - 2 + 7x + 4 = 90

Combine common terms

22x + 2 = 90

Solve for x

22x = 88

x = 4

Now you can plug x into the equation for each angle to find its value.

Angle BAC

15x - 2 = 15(4) - 2 = 60 - 2 = 58 degrees

Angle CAD

7x + 4 = 7(4) + 4 = 28 + 4 = 32 degrees

Answer:

[tex]\displaystyle y=-\frac{1}{2}x+1[/tex]

Step-by-step explanation:

The equation of any line in slope-intercept form is:

y=mx+b

Being m the slope and b the y-intercept.

Assume we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Two points are given: (-6,4) and (-2,2). Calculating the slope:

[tex]\displaystyle m=\frac{2-4}{-2+6}=\frac{-2}{4}=-\frac{1}{2}[/tex]

The equation of the line is, so far:

[tex]\displaystyle y=-\frac{1}{2}x+b[/tex]

To calculate the value of b, we use any of the given points, for example (-6,4):

[tex]\displaystyle 4=-\frac{1}{2}(-6)+b[/tex]

[tex]\displaystyle 4=3+b[/tex]

Solving:

b = 1

The equation of the line is:

[tex]\boxed{\displaystyle y=-\frac{1}{2}x+1}[/tex]

We can see none of the choices is correct.

Step-by-step explanation:

This question is really asking for the perimeter of the rectangle. The two of the longest sides is 14 units, the other 2 are 11 units. 14 + 14 + 11 + 11 = 50 units/ 1 unit is 10m, so 50 by 10 is 500, 500 meters.

The length of three sides of triangle is,

               [tex]a=6.8m\\\\b=8.8m\\\\c=26.4m[/tex]

Perimeter is the sum of all three sides of triangle.

Let us consider that side b of triangle is x.

Given that, Side (a) is two less than side (b) and side (c) is triple side (b).

So that, sides of triangle are,

                    [tex]a=x-2\\\\b=x\\\\c=3x[/tex]

Perimeter of triangle are,

              [tex]x-2+x+3x=42\\\\5x=44\\\\x=44/5=8.8[/tex]

Side [tex]a=8.8-2=6.8m,b=x=8.8m,c=3x=3*8.8=26.4m[/tex]

Answer:

C. If an animal is a dog, then it is a golden retriever; false

Step-by-step explanation:

Logical reasoning is an important aspect of mathematics.

The conditional statements in the question are represented by the letters p and q. The if-then statement in which the statement p will lead to a conclusion in q is a glaring characteristic of conditional statements. A conditional will be held to be true unless a statement that is true has a false conclusion derived from it.

In the question above, the conditional statement is; If an animal is a dog, then it is a golden retriever. We can clearly see that this conclusion is false.

Answer:

For the first three situations, the sum is zero.

Step-by-step explanation:

As the expenses are negative of earnings, so assuming the earning amount is positive while the spending amount is negative.

Shawna spends $20 and she earns $20,

So, the sum of the total amount is

-20+20=0

A diver dove down 20.14 feet under-water and then descended 20.14 feet.

First, the diver ascends 20.14 feet then descends the same.

As the ascending and the descending are opposite to each other.

The sum of both is

+20.14-20.14=0

So, in this case, the diver has a sum of zero.

For shooting over par the golfer have +2 points while for shooting under par the golfer have -2 points,

So, the total points are

+2-2=0

So, in this case, the golfer has a sum of zero points.

In the last case, you already have $5.50 in your pocket and then you receive $5.50 for doing your chore.

This time, there is an addition of $5.50 to the money you already have.

So, the total money, after receiving the $5.50 is

$5.50+$5.50=$11

In this case, the sum of the total amount is not zero.

Hence, for the first three situations, the sum is zero.

The next three terms of Sequence is 2, 7, 12.

A grouping of numbers in a specific order is known as a sequence. On the other hand, a series is described as the accumulation of a sequence's constituent parts.

Each number in the sequence is called a term. In the sequence 1, 3, 5, 7, 9, …, 1 is the first term, 3 is the second term, 5 is the third term, and so on.

Given:

-18, -13, -8, -3,…

Now, the common difference = -13 - (-18)= -13 + 18 = 5

So, the formula for nth term will be

[tex]a_n[/tex] = -18 + 5(n-1)

Then,  n= 5th term

[tex]a_n[/tex] = -18 + 5(5-1)

[tex]a_n[/tex] = -18 + 5(4)

[tex]a_n[/tex] = -18 + 20

[tex]a_n[/tex] = 2

and, n= 6th term

[tex]a_n[/tex] = -18 + 5(6-1)

[tex]a_n[/tex] = -18 + 5(5)

[tex]a_n[/tex] = -18 + 25

[tex]a_n[/tex] = 7

and, n= 7th term

[tex]a_n[/tex] = -18 + 5(7-1)

[tex]a_n[/tex] = -18 + 5(6)

[tex]a_n[/tex] = -18 + 30

[tex]a_n[/tex] = 12

Hence, the next three terms are 2, 7, 12.
