Answer:

Step-by-step explanation:

−5x+15<−2x+6

Step 2: Add 2x to both sides.

−5x+15+2x<−2x+6+2x

−3x+15<6

Step 3: Subtract 15 from both sides.

−3x+15−15<6−15

−3x<−9

Step 4: Divide both sides by -3.

Solve each of the following equations for the missing variable.

2x – 14 = -9

x = 10

x = 2.5

x = -2.5

x = -10

Answers

Answer: x = 2.5

Step-by-step explanation: Add 14 to both sides. After that take the number left on the right side (5) and divide it by 2. That leaves you with x = 2.5

the answer to the question is 2.5

Which statement best explains whether △ABC is congruent to △DEF?

△ABC is congruent to △DEF because △ABC can be mapped to △DEF by a reflection across the y-axis followed by a translation 5 units down.

△ABC is congruent to △DEF because △ABC can be mapped to △DEF by a rotation of 90° counterclockwise about the origin followed by a reflection across the y-axis.

△ABC is congruent to △DEF because △ABC can be mapped to △DEF by a translation 5 units down followed by a reflection across the x-axis.

△ABC is not congruent to △DEF because there is no sequence of rigid motions that maps △ABC to △DEF.

Answers

Answer: △ABC is congruent to △DEF because △ABC can be mapped to △DEF by a translation 5 units down followed by a reflection across the x-axis.

Step-by-step explanation: By moving the shape down 5 units, you are met with DEF. You then mirror it (reflect) across the y axis.

Answer:

y = - 1 and x = 8

Step-by-step explanation:

The equation of a horizontal line parallel to the x- axis is

y = c

where c is the value of the y- coordinates the lune passes through.

The line passes through (8, - 1) with y- coordinate - 1, thus

y = - 1 ← equation of horizontal line.

--------------------------------------------------------------------

The equation of a vertical line parallel to the y- axis is

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (8, - 1) with x- coordinate 8 , thus

x = 8 ← equation of vertical line

Answer:

20.75(8)+0.42(15)

Step-by-step explanation:

I did 0.42 because that is the cost per one pansy. While she is getting 8 trees so you multiply the cost of one tree by the number of trees total to get the total cost for all of the trees together. Then 0.42*15 is the total amount of money she will spend on pansies. Once she knows how much she will spend on pansies then she can by the six packs but if she was to buy 2 six packs she would still need to get half a pack of pansies to get 15 because 15 does not go into 6 evenly.

Sally buys a shirt of 5.00. New York's sales tax is 8.200. What is the final price?

Show your work and explain or I report and delete answer.

Answers

Answer: $5.40

Sales tax is a price you add to every 100 cents purchased.

Sally purchased a shirt of 5.00, and New York's sales tax is 8.200.

So, we multiply 8 by 5. We get the number 40, right?

You now add 0.40 to 5.00.

The answer totals at 5.40 because 5.00 + 0.40 = 5.40.

HELP PLSSSSS AAAAAAAAAAAAAAAAAAAAAA ILL GIVE BRAINLIEST B(

Answer:

a(n) = (3/5)a(n-1), where a(1) = 10 and n is 2 or greater.

Step-by-step explanation:

determine the common factor...The first term (10) by 3/5 results in the given second term (6); the third term is 3/5 of the second term (6), resulting in 18/5 (equivalent to 36/10 or 3.6/1, or just 3.6. Resulting in a(n) = (3/5)a(n-1).

the third term is 3.6, which, if mult. by (3/5), produces 2.16, as expected.

Thus, the recursive formula for this geometric sequence is a(n) = (3/5)a(n-1).

This is good only for a(1) = 10 and n = 2, 3, ....
