question down below thanks

Answer:

(2)

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 line passes through.

The line passes through (1, - 2) with y- coordinate - 2, thus

y = - 2 ← is the equation of the line

Answer:

3) Midpoint is (-4,0.5)

Option A is correct.

4) Midpoint is (2.5,0)

Option B is correct.

5) The factors are (x+4)(x-7)

Option C is correct.

6) The factors are (x+4)(x+2)

Option A is correct.

Step-by-step explanation:

Question 3

Find midpoint of the following:

(2,-7), (-10,8)

The formula used to find midpoint is: [tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )[/tex]

We have [tex]x_1=2, y_1=-7, x_2=-10,y_2=8[/tex]

Putting values and finding midpoint

[tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )\\Midpoint=(\frac{2-10}{2},\frac{-7+8}{2} )\\Midpoint=(\frac{-8}{2},\frac{1}{2} )\\Midpoint=(-4,0.5 )[/tex]

So, Midpoint is (-4,0.5)

Option A is correct.

Question 4

Find midpoint of the following:

(2,-10), (3,10)

The formula used to find midpoint is: [tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )[/tex]

We have [tex]x_1=2, y_1=-10, x_2=3,y_2=10[/tex]

Putting values and finding midpoint

[tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )\\Midpoint=(\frac{2+3}{2},\frac{-10+10}{2} )\\Midpoint=(\frac{5}{2},\frac{0}{2} )\\Midpoint=(2.5,0 )[/tex]

So, Midpoint is (2.5,0)

Option B is correct.

Question 5

Factor each completely

[tex]x^2-3x-28[/tex]

We will break the middle term and find factors

[tex]x^2-3x-28\\=x^2-7x+4x-28\\Taking\:common\\=x(x-7)+4(x-7)\\=(x+4)(x-7)[/tex]

So, the factors are (x+4)(x-7)

Option C is correct.

Question 6

Factor each completely

[tex]x^2+6x+8[/tex]

We will break the middle term and find factors

[tex]x^2+6x+8\\=x^2+4x+2x+8\\=x(x+4)+2(x+4)\\=(x+4)(x+2)[/tex]

So, the factors are (x+4)(x+2)

Option A is correct.

Answer:

It would be $ 564,300 so C

Step-by-step explanation:

just took the test

She made 564300 dollars in total when she sells the apartment.

An equation consists of terms and variables on both sides of the equality sign and they are equal.

Given Rosalyn is planning to sell her apartment complex.

She bought this apartment 10 years for 420000 dollars and every year the apartment gains 2.2% in value.

∴ After 10 years the value of the apartment is,

A = P( 1 + r/100)ⁿ.      where n is time in years.

A = 420000( 1 + 2.2/100)¹⁰.

A = 420000( 1.022)¹⁰.

A = 420000×1.243 dollars.

A = 522105.48 dollars.

She charges a monthly rent of 720 dollars for each room and has 8 rooms in it.

∴ Monthly earnings from the apartment are (720×8) = 5760 dollars.

And we know 10 years is 120 months.

∴ In 10 years her earnings from rent are

= 5760×120 dollars.

= 691200 dollars.

The upkeep cost is 22900 dollars per year therefore it is 229000 dollars for 10 years.

∴ The profit she will have selling her apartment is (522105.48 - 420000 + 691200 - 229000) dollars.

= 564305.48 dollars.

= 564300 dollars.

Answer:

-9.1r + 3.9

Step-by-step explanation:

-6.2r - 4.6 -2.9r + 8.5

-6.2r and -2.9r are alike, so we combine.

-6.2r + -2.9r = -9.1r

-4.6 and 8.5 are alike, so we combine.

-4.6 + 8.5 = 3.9

Answer:

x = 17.5

Step-by-step explanation:

[tex] \triangle ABC \sim \triangle DEF... (given)[/tex]

[tex] \therefore \frac{AB}{DE} = \frac{BC}{EF} [/tex]

[tex] \therefore \frac{10}{4} = \frac{x}{7} [/tex]

[tex] \therefore 2.5 = \frac{x}{7} [/tex]

[tex] \therefore 2.5\times 7= x[/tex]

[tex] \therefore 17.5= x[/tex]

Answer:

  SAS

Step-by-step explanation:

Count the number of sides marked congruent. One is marked with a single hash mark, and one is marked with a double hash mark, for a total of two.

That means the chosen congruence theorem will have S appear twice in its name, excluding AAS, ASA, and SSS.

We also note that the angles between the marked sides are vertical angles, hence congruent. The theorem that depends on two sides (SS) and the angle between them (_A_) is the SAS theorem.

Answer:

h(t)=3/2t+59

h(t)=2/3(15)+64                        h(t)=2/3(30)+64

74=  10+64                              84=20+64

74=74                                      84=84

when a number is raised to the power of a rational number it becomes a root of the denominator's order and the number inside the root is raised by the power of the numerator

for example

[tex]x^{\frac{a}{b} }=\sqrt[b]{x^a}[/tex]

in this case

[tex]32^{\frac{3}{5} }=\sqrt[5]{32^3}[/tex]

[tex]=\sqrt[5]{32768}[/tex]

Answer:

9. By every 10 seconds, the meters traveled increase by a constant of 8.5 meters.

10. (1,2), (2,4), (5,10), (8,16)

Step-by-step explanation:

For question 9, here is an example. You can find the constant of proportionality by dividing 85 by 10, which is 8.5. So every 10 seconds, the distance traveled in meters by the object will have multiplied by 8.5. You can also do 170 divided by 20, which is also 8.5 thus verifying our answer. Hope this helps you, sorry I couldn’t explain it better.

50miles

Step-by-step explanation:

Answer:

500 miles

Step-by-step explanation:

80% is converted to its decimal form 0.8

Multiply 0.8 times "x" which is the unknown total distance of the trip (80% of the total trip) to get 400 because 80% of the trip is 400 miles. Then find x

0.8x = 400

400/0.8 = x

500 = x

Answer:

B

Step-by-step explanation:

-3/4y - 1/5y = 380 can be simplified to -19/20y = 380.

In order for the student to incorrectly get 361, they likely just multiplied the 380 by 19/20 rather than multiplying by the reciprocal (which would be -20/19).

This means the best answer should be B.

Step-by-step explanation:

Given

f(x) = 2x + 6

g(x) = 3x²

f(g(-3)) = ?

Now

g(-3) = 3 * (-3)²

= 3* 9

=27

Also,

f(g(-3)) = f(27)

= 2* 27 + 6

= 60
