Answer:

d is 90, angles on a straight line

e is 147, vertically opp angles

f is 33, any of the above rules.

Answer:

If two angles are vertical angles, then they are congruent.

Step-by-step explanation:

If two angles are vertical angles, then they are congruent- this  justifies why ∠FBE measures 50°.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

We know that, a ray is a line that continues on forever inn one direction with a point at it's start.

Here, given that,

angles ABD and DBC are complementary

Now, we get,

Hence,  If two angles are vertical angles, then they are congruent- this  justifies why ∠FBE measures 50°.

The area of the floor required to cover using carpet is equal to 24 square yards .

To calculate the area of the room in square yards,

convert the dimensions from feet to yards and then find the product of the length and width.

1 yard (yd) = 3 feet (ft)

Room length in yards

= 18 feet / 3 feet/yd

= 6 yards

Room width in yards

= 12 feet / 3 feet/yd

= 4 yards

Now, find the area of the room in square yards:

Area = Length × Width

Area = 6 yards × 4 yards = 24 square yards

Therefore,  24 square yards of carpet area required to cover the floor of the room.

Answer:

For question one, your answer is that the daily change in the stock market is 13 points

(You would basically be dividing for both answers)

For question two, the answer is around 6 feet in depth

Step-by-step explanation:

Answer:

1.) 13

2.)either 600 or -600

Step-by-step explanation:

For #1, you would Divide 5 from 65 which equals 13.

For #2, all you practically do is multiply 60 by 10 which equals 600 but since u are going underwater (depth) it would most likely be -600

Answer:

y=-3x+9

Step-by-step explanation:

The slope of the line through two points (x1,y1) and (x2,y2) can be found by using the formula below.  Don't forget slope is rise over run: subtract the y-values in the numerator to get the rise and subtract the x-values in the denominator (in the same order!) to get the run. Once you know the slope (m), you're halfway there.  Now all that's left to find is the y-intercept (b).  To find the y-intercept, choose one of the points on the line.  It does not matter which point you choose (just pick the one that looks easiest to you).  Plug in the values for x and y into the equation and solve for b.

Answer:

y = x + 5

Step-by-step explanation:

Find any two points:

(1, 6)

(2, 7)

Slope = (y2 - y1) / (x2 - x1)

S0:

7 - 6 / 2 - 1

1 / 1

So slope = 1

Equation:

y = mx + b

Plug in the numbers using the x and y of any points:

7 = m * 2 + b

Add m (which is the slope):

7 = 1 * 2 + b

7 = 2 + b

Subtract two from both sides:

5 = b

So our equation is:

y = x + 5

Please let me know if I've done anything wrong!

Answer:

y = x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (0, 5) ← 2 points on the line

m = [tex]\frac{5-0}{0+5}[/tex] = [tex]\frac{5}{5}[/tex] = 1

The line crosses the y- axis at (0, 5 ) ⇒ c = 5

y = x + 5 ← equation of line

Answer:

C. An arithmetic sequence with a common difference of 6.

Step-by-step explanation:

A is incorrect because the common difference is not -9 (not constant).

B is incorrect because the common difference is not 3 (not constant).

C is the correct answer because the common difference is 6 (constant).

D is incorrect because this is an arithmetic sequence.

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

-9 + 6 = -3

-3 + 6 = 3

3 + 6 = 9

9 + 6 = 15

The common difference is +6 (positive 6).

Hope that helps!

Please give me Brainliest!?!?

The progression −9, −3, 3, 9, 15 is an arithmetic sequence with a common difference of 6. The correct option is C.

The sequence in which every next number is the addition of the constant quantity in the series is termed the arithmetic progression.

Given series is −9, −3, 3, 9, 15.

The common difference is calculated as,

-9 + 6 = -3

-3 + 6 = 3

3 + 6 = 9

9 + 6 = 15

As above it is observed that with the common difference of 6 we found the series,  −9, −3, 3, 9, 15.

Therefore, the progression −9, −3, 3, 9, 15 is an arithmetic sequence with a common difference of 6. The correct option is C.

Answer:

-2

Step-by-step explanation:

Rearrange:4*x+12-(-2*x)=0

Pull out like factors:6x + 12  =   6 • (x + 2)

Solve:x+2=0

Subtract 2 from both sides of the equation:x = -2

Answer:

x = -2

Step-by-step explanation:

4x + 12 = -2x

4x + 12-12 = -2x - 12

4x = -2x - 12

4x + 2x = -2x - 12 + 2x

6x = -12

x = -2

Answer:

147 gallons per hour

Step-by-step explanation:

Given:

36 3/4 gallons = 15 minutes

Determine the water rate in gallons per hour

1 hour = 60 minutes

60 minutes / 15 minutes = 4

Multiply both a of the proportion by 4

36 3/4 × 4gallons = 15 minutes × 4

147/4 × 4 gallons = 60 minutes

147 gallons = 60 minutes

147 gallons per hour

The correct answer = 147 gallons per hour

The correct value of x is 4.

It is required to find the solution.

A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.

Given:

The equation is

1 – (2x + 4) = –4x + 5,

we have to find the correct solution of the equation;

According to given question we have,

Step 1: Open the parenthesis we  get,

1 – (2x + 4) = –4x + 5

1-2x-4 = -4x + 5

1-4-2x = -4x +5

-3-2x = -4x + 5

Step 2: Collect like terms we  get,

-2x + 4x = 5 + 3

2x = 8

Step 3: divide both sides by 2 we  get,

2x/2 = 8/2

x = 4

Hence the correct value of x is 4.

Answer: Plz mark me brainlest

Step-by-step explanation:

You can factor out a 2, so do that first

2(x^2 - 13x + 30) = 0

Now look at x^2 - 13x + 30.  Since you have a positive last term and a negative middle term, then you're looking for something in the form of (x - ?)(x - ?).  We have to find two numbers whose product is 30 and whose sum is 13.  The numbers must be 10 and 3:

2(x-3)(x-10) = 0

82 is the value of the expression when z = 3

Step-by-step explanation:

Plug in 3 to the expression.

[tex]10z^{2} -2z - 2\\ 10(3)^{2} - 2(3) - 2[/tex]

Then solve the expression.

90 - 6 - 2 = 82

We got 90 when we squared 3 and multiplied that number (9) by 10, resulting in 90.

YOU SUBTRACT -4 ON BOTH SIDES SO YOU'LL GET X= 1/4

Answer:

x= 1/4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3/2(2−6x)+1=3−5x

(3/2)(2)+(3/2)(−6x)+1=3+−5x (Distribute)

3+−9x+1=3+−5x

(−9x)+(3+1)=−5x+3 (Combine Like Terms)

−9x+4=−5x+3

−9x+4=−5x+3

Step 2: Add 5x to both sides.

−9x+4+5x=−5x+5x+3

−4x+4=3

Step 3: Subtract 4 from both sides.

−4x+4−4=3−4

−4x=−1

Step 4: Divide both sides by -4.
