Which of these equations has a solution of x = 2? Select three that apply. A 6(2x – 1) = 4 + 7x B 10 – 3x = –2(x + 4) C –3(7 – 2x) = –1 – 4x D 7x + 12 = 2(4x – 5) E –5(x + 1) = –4 – 7x F 8x + 11 = 9(5 – x)

Answers

Answer 1

Answer:

x = 2 for a, c, and f

Step-by-step explanation:

a)

6(2x - 1) = 4 + 7x

12x - 6 = 4 + 7x

5x = 10

x = 2

b)

10 - 3x = -2(x + 4)

10 - 3x = -2x - 8

18 = x

c)

-3(7 - 2x) = -1 - 4x

-21 + 6x = -1 - 4x

10x = 20

x = 2

d)

7x + 12 = 2(4x - 5)

7x + 12 = 8x - 10

22 = x

e)

-5(x + 1) = -4 - 7x

-5x - 5 = -4 - 7x

2x = 1

x = 1/2

f)

8x + 11 = 9(5 - x)

8x + 11 = 45 - 9x

17x = 45 - 11

17x = 34

x = 2

A garden patio is covered wit grey slabs and yellow slabs .1/5 of the slabs are grey a)write down the ratio of grey slabs to yellow slabs give your answer in its simplest form b)there are 55 slabs in total work out the number of yellow slabs

Answers

Answer:

1:u

Step-by-step explanation:

Grey slabs = 1/5 of total slab

Say total slab = x

Then,

Grey slabs = 1x/5

We can represent

Yellow slabs = u/5

Then ratio of Grey to yellow would be;

Gray slabs / Yellow slabs = (1x/5)/(u/5)

=1/u

= 1:u

Since there are 55 slabs in total, then

Yellow slab would be = 55/5 = 11

Last four steps that could perform to solve the equation 4(3x-20)-x=16-x

Place the steps in correct order

Add x to both sides, add 20 to both sides, divide both sides by 3, add 16 to both sides, divide both sides by 4, divide both sides by 12, distribute 4 to get 12x-20

Distribute 4 to get 12x-20
Add x to both sides
Add 20 to both sides
Divide both sides by 12

9514 1404 393

Answer:

add x to both sidesdivide both sides by 4add 20 to both sidesdivide both sides by 3

Step-by-step explanation:

Your steps in order would be ...

add x to both sidesdivide both sides by 4add 20 to both sidesdivide both sides by 3

__

Executing these steps, we get ...

  4(3x -20) = 16 . . . . . add x

  3x -20 = 4 . . . . . . . . divide by 4

  3x = 24 . . . . . . . . . . .add 20

  x = 8 . . . . . . . . . . . . . divide by 3, giving the solution

_____

Additional comment

If you were to distribute the 4 first, you would have ...

  12x -80 -x = 16 -x

Now, you can add x and add 80 to get ...

  12x -80 = 16

  12x = 96

Then dividing by 12 gives ...

  x = 8

You will notice that these steps do not match steps available in your list.

Your Olympic team wins 48 medals in the spring. The medals are gold, silver, and bronze in a ratio of 2 : 1 : 5. How many of each medal did your team win?

Answers

Answer:

12, 6 and 30

Step-by-step explanation:

Step one:

given data

Number of medals = 48 medals

The given ratio is = 2:1:5

The total ratio is = 2+1+5= 8

Step two;

Applying the part to all method

for Gold we have

2/8=x//48

cross multiply

8x= 48*2

divide both sides by 8

x= 96/8

x= 12

gold is 12

for silver we have

1/8=x//48

cross multiply

8x= 48*1

divide both sides by 8

x= 48/8

x= 6

silver is 6

for bronze we have

5/8=x/48

cross multiply

8x= 48*5

divide both sides by 8

x= 240/8

x= 30

Bronze  is 30

The most important outcome of the Adams-Onis Treaty of 1821 was that Florida became a territory of the United States. Spain no longer had a US presence. Spain gave up rights to Alabama and Georgia. Florida became the twenty-seventh state to enter the Union.

Answers

Answer:

Florida became a territory of the United States.

Step-by-step explanation:

i got it right on Edge

The correct option for the given statement is Florida became a territory of the United States.

Adams-Onís TREATY:-

The Adams-Onís Treaty between the United States and Spain was negotiated by Secretary of State John Quincy Adams and the Spanish Minister to the United States, Don Luis de Onís, and signed in February 1819.

The principal elements in the treaty were the acquisition of Florida by the United States and the establishment of a boundary line between Spanish territory and the United States.

After the Louisiana Purchase in 1803, Pres. Thomas Jefferson argued that Florida was included in Louisiana. In 1810 and 1812 the United States annexed sections of West Florida.

In the treaty Spain gave East and West Florida to the United States, and the United States agreed to assume claims by citizens of the United States against Spain.

Hence, the answer is Florida became a territory of the United States.

A line passes through the point (8,-9) and has a slope of -5/4.
Write an equation in point-slope form.

Answers

Answer:

 y=-5/4x-19

Step-by-step explanation:

y=-5/4(x(-8))-9

y=-5/4x-10-9

y=-5/4x-19

1. Slope
M = -5/4

2. Y- intercept
Y = mx + b
-9 = (-5/4)(8) + b
-9 = -10 + b
-9 + 10 = -10 + 10 + b (the ten cancels out and we are just left with our b)
1 = b

So, therefore, the equation is:

Identify the asymptotes, domain, and range
f(x)=-1/x+4

Just do number 2 at the least, if you want to do more ill give brainliest

Answers

Domain is -1 and the range is 4.

1.

[tex]f(x)=\dfrac1{x-1}=\dfrac1{x-1}+0[/tex]

x-1 = 0  for  x = 1

so:

Vertical asymptote: x = 1

Domain:  Dom f = R\{1}  {or: Dom f = (-∞, 1)∪(1, ∞)}

Horizontal asymptote:  y = 0

Range:    Ran f=R\{0}  {or: Ran f = (-∞, 0)∪(0, ∞)}

2.

[tex]f(x)=\dfrac{-1}{x}+4=\dfrac{-1}{x-0}+4[/tex]

x-0 = 0  for  x = 0

so:

Vertical asymptote: x = 0

Domain:  Dom f = R\{0}  {or: Dom f = (-∞, 0)∪(0, ∞)}

Horizontal asymptote:  y = 4

Range:    Ran f=R\{4}  {or: Ran f = (-∞, 4)∪(4, ∞)}

3.

[tex]f(x)=\dfrac{1}{x+3}-3[/tex]

x+3 = 0  for  x = -3

so:

Vertical asymptote: x = -3

Domain:  Dom f = R\{-3}  {or: Dom f = (-∞, -3)∪(-3, ∞)}

Horizontal asymptote:  y = -3

Range:    Ran f=R\{-3}  {or: Ran f = (-∞, -3)∪(-3, ∞)}

4.

[tex]f(x)=\dfrac{-1}{x+5}-6[/tex]

x+5 = 0  for  x = -5

so:

Vertical asymptote: x = -5

Domain:  Dom f = R\{-5}  {or: Dom f = (-∞, -5)∪(-5, ∞)}

Horizontal asymptote:  y = -6

Range:    Ran f=R\{-6}  {or: Ran f = (-∞, -6)∪(-6, ∞)}

4.

[tex]f(x)=\dfrac{-1}{x+1}+3[/tex]

x+1 = 0  for  x = -1

so:

Vertical asymptote: x = -1

Domain:  Dom f = R\{-1}  {or: Dom f = (-∞, -1)∪(-1, ∞)}

Horizontal asymptote:  y = -6

Range:    Ran f=R\{3}  {or: Ran f = (-∞, 3)∪(3, ∞)}

5.

[tex]f(x)=\dfrac{1}{x+4}-2[/tex]

x+4 = 0  for  x = -4

so:

Vertical asymptote: x = -4

Domain:  Dom f = R\{-4}  {or: Dom f = (-∞, -4)∪(-4, ∞)}

Horizontal asymptote:  y = -2

Range:    Ran f=R\{-2}  {or: Ran f = (-∞, -2)∪(-2, ∞)}
