Answer:

x= -8

collect like term than divide both sides

6x-4x = -20+4

2x= -20+4

2x=-16

x= -8

Answer:

Step-by-step explanation:

6x-4=4x-20 Solve for X

6x-4x = -20+4

2x = -16

x = -8

proof

6(-8) - 4 = 4(-8) - 20

-52=-52

Answer:

y = 2x

Step-by-step explanation:

Coordinates:

(1, 2)

(0, 0)

Slope = 2/1 = 2

y = mx + b

2 = 1 * 2 + b

2 = 2 + b

b = 0

So:

y = 2x

Answer:

It will take 3 days for their bird feeders to contain the same amount of bird seed

Step-by-step explanation:

Let the number of days it will take their bird feeder to contain the amount of bird seed be x

For Edith, the amount of birdseeds that will be left after x days will be;

4 1/2 - 3/4(x)

= 9/2 - 3x/4

For June, the amount of birdseeds that will remain after x days will be;

3 - 1/4(x)

= 3 - x/4

Since after x days, the amount of birdseeds will be equal;

Mathematically;

9/2 - 3x/4 = 3 - x/4

Let’s work with decimals to make things easier;

4.5 - 0.75x = 3 - 0.25x

4.5 -3 = -0.25x + 0.75x

1.5 = 0.5x

x = 1.5/0.5

x = 3

Answer:

$4,351.48

Step-by-step explanation:

This is because if you take 6,000 and use the part over whole method, 6,000 x 100 = 600,000 divided bt 105.5 = 5,687.20, continue that with the same numbers, except you replace the part with the last answer you got.

6,000 after 6 months

5,687.20 after 5 months

5,390.72 after 4 months

5,109.68 after 3 months

4,843.30 after 2 months

Answer:

See Below

Step-by-step explanation:

Ok, so you got:

The sum of twice a number and 5 is at most 15

Sum means we are going to add two things together, soo . .

___+___

Is at most means we are going to have:

___+___≤ ___

Twice a number  and 5= 2x(a variable)  + 5

(I'm going to use a as my variable, use whichever you like or are given)

2a + 5 ≤ __

Which will result in being greater than or equal to 15

So, your final equation would be:

2a + 5 ≤ 15

Answer:

Answer: image below is the answer

Step-by-step explanation:

$1.80 + $1.20 = $3.00  <  $1.86 + $1.23  <  $2.00 + $1.50 = $3.50

Double these supplies will cost between 2 × $3.00 and 2 × $3.50.

2 x $1.23 = $2.46

Think about more items Kira could buy so that her total cost is more than $4 but less than $6.

$1.80 + ($1.10 x 2) = $4.00  <  $1.86 + ($1.23 x 2)  <  $2.00 + ($1.25 x 2) = $4.50

Think about more items Ida could buy so that her total cost is more than $8 but less than $9.

the total angle of a straight line like this hypotenuse would be 180. So it's 180-118=62

Answer: No solutions (C)

Explanation: The two lines have the same slope but different Y intercept this means they will increase/decrease at the same rate but since they start at different locations on a graph, they will never touch making it parallel

Answer:

[tex]d = 10[/tex]

Step-by-step explanation:

[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Simply plug in the 2 coordinates into the distance formula to find distance d:

[tex]d = \sqrt{(-2-6)^2+(4-(-2))^2}[/tex]

[tex]d = \sqrt{(-8)^2+(4+2)^2}[/tex]

[tex]d = \sqrt{64+(6)^2}[/tex]

[tex]d = \sqrt{64+36}[/tex]

[tex]d = \sqrt{100}[/tex]

[tex]d = 10[/tex]

Answer:

10 units

Step-by-step explanation:

( x1, y1) =A(6,-2)

(x2, y2) =B(-2,4)

Using distance formula,

AB ^2 = (x2-x1) ^2 +(y2-y1) ^2

=(-2-6)^2 +(4+2)^2

=64+36

=100

Therefore, AB=10 units

Answer:

yes

Answer:

3 hours

Step-by-step explanation:

Let the number of hours worked = x

Delicious Doing caterers events at a flat rate $500 plus $100 per hour after the first 2 hours.

$500 + $100 × x

500 + 100 × 1

After the first 2 hours = $500 + $100

= $600

After the first 3 hours = $500 + $100 × 2

= $700

Cathy's Catering has a flat rate of $620 per event plus $70 per hour after the first three hours.

$620 + $70 × x

620 + 70x

After the first 3 hours

= $600 + $70

= $670

What is the most amount of hours you could hire Cathy's Catering for and it cost less than Delicious Doings?

The Inequality is given as:

Cathy's Catering for < Delicious Doings

620 + 70x < 500 + 100x

Collect like terms

620 - 500 < 100x - 70x

120 < 30x

120/30 < x

4 < x

Therefore, the most amount of hours the most amount of hours you could hire Cathy's Catering for and it cost less than Delicious Doings is 3 hours
