a) 2x -1.5 = 2x - 1.5
-
b) 2v + 4 = -1

Answers

Answer 1

Answer:

a) all real numbers

b) v = -2.5

Step-by-step explanation:

a) 2x - 1.5 = 2x - 1.5

subtract 2x from both sides of the equation

2x - 1.5 - 2x = 2x - 1.5 - 2x

1.5 = 1.5

since 1.5 will always equal 1.5 regardless of what x is,

the solution is all real numbers

b) 2v + 4 = -1

subtract 4 from both sides of the equation

2v + 4 - 4 = - 1 - 4

2v = -5

divide both sides of the equation by 2

2v/2 = -5/2

v = -2.5

Find the distance between (-1,2) and (4,0)

Answers

The distance between the two points would be the square root of 29. The decimal for that number would be 5.4

Answer:  The distance between (-1,2) and (4,0) is about 5.4 units

Step-by-step explanation:  You can use the Pythagorean Theorem to calculate the distance.

The difference in x-values is one side of the triangle  4- (-1) = 5  Side a

The difference in y-values is the other side  0- 2 = -2  Side b

The distance you are looking for is the hypotenuse, side c

Pythagorean Theorem : substitute the numbers we found for a and b

c² = a² + b²

c² = 5² + -2²

c² = 25 + 4

c² = 29    

29  is the "square on the hypotenuse."  So take the square root (use a calculator)

√29 = 5.385

You can round that to 5.4 units

Rectangle RSFT has vertices R(3,10), S(5,10), F(5,6) and T(3,6). RSFT was reflected over the line
y = x, to form R'S'F'T'. What are the coordinates of the vertices of the image?

Answers

Answer:

The coordinates of the vertices of the image are R' (10, 3), S' (10, 5), F' (6, 5), T' (6, 3)

Step-by-step explanation:

If the point (x, y) reflected across the line y = x, then its image is (y, x)If the point (x, y) reflected across the line y = -x, then its image is (-y, -x)

Let us use the first rule above to solve the question.

∵ Rectangle RSFT has vertices R (3, 10), S (5, 10), F (5, 6), and T(3, 6)

∵ RSFT was reflected over the line, y = x

→ To find its image switch the coordinates of all the vertices

∵ R = (3, 10)

R' = (10, 3)

∵ S = (5, 10)

S' = (10, 5)

∵ F = (5, 6)

F' = (6, 5)

∵ T = (3, 6)

T' = (6, 3)

The coordinates of the vertices of the image are R' (10, 3), S' (10, 5), F' (6, 5), T' (6, 3)

Step-by-step explanation:

The new rate is just [tex]\$ \ 175[/tex] per month, let's call it rate A:

[tex]\to A = 175[/tex]

The new price is [tex]\$ \ 94[/tex] plus[tex]\$ \ 4.50[/tex] per device and let us name it rate B:

Ashley has 5 bags of flour. She has two smaller bags with .75 ounces in each and 3 bigger bags which has 1.14 ounces in each. How much flour does she have in total?

Answers

Answer:

4.92 ounces

Step-by-step explanation:

Ashley has 5 bags of flour

She has two smaller bags with .75 ounces in each

= 2 × 0.75 ounces

= 1.5 ounces

3 bigger bags which has 1.14 ounces in each.

= 3 × 1.14 ounces

= 3.42 ounces

How much flour does she have in total?

This is calculated as

1.5 ounces + 3.42 ounces

= 4.92 ounces

Therefore she has 4.92 ounces of flour in total.

A football team needs to move the ball at least 10 yards forward from the original starting point in order to get a first down. Angel runs for 6 yards on the first play. On the second play, he is sacked for −9 yards. At least how many yards does his team need on the third play to get a first down?

Answers

Answer:

13 yards

Step-by-step explanation:

Given that:

To get a first down, ball needs to be moved 10 yards forward from original starting point.

Distance on first play = 6 yards

on second play = - 9 yards

Hence to get a first down, distance on third play should be:

Let distance needed on third play = d

Hence,

Sum of distance on all three plays should be = 10

6 + (-9) + d = 10

6 - 9 + d = 10

-3 + d = 10

d = 10 + 3

d = 13 yards

Kevin moved from a city to a small town. The population of the city is 8*10^4 is about 20 times as great as the small town. What is the approximate population of the small town?

Answers

Given:

Population of city = [tex]8\times 10^4[/tex]

It is about 20 times as great as the small town.

To find:

The approximate population of the small town.

Solution:

Population of city is about 20 times as great as the small town. It means,

[tex]\text{Population of city}=20\times \text{Population of small town}[/tex]

[tex]\dfrac{\text{Population of city}}{20}=\text{Population of small town}[/tex]

On substituting Population of city = [tex]8\times 10^4[/tex], we get

[tex]\text{Population of small town}=\dfrac{8\times 10^4}{20}[/tex]

[tex]\text{Population of small town}=\dfrac{8\times 10\times 10^3}{20}[/tex]

[tex]\text{Population of small town}=4\times 10^3[/tex]

Therefore, the population of the small town is [tex]4\times 10^3[/tex].
