Question
Find the equation of the line with slope m
=
2 that contains the point (8,19).

Answers

Answer: y= 2x + 3

Step-by-step explanation:

Point slope formula: y = mx + b

Since the given point is (8,19), 19 is our y, and 8 is our x. Since the slope is 2, our m is 2.

Sub in values.

y = mx + b

19 = 2(8) +b

19 = 16 + b

b = 19-16

b = 3

Now that we have m and b, we can make the equation.

y = mx + b, sub in 2 for m and 2 for b

y = 2x + 3

19 = 2(8) + 3

19 = 16 + 3

19 = 19

So the answer is y = 2x+3

A triangle has a perimeter of 48 feet. If the three sides of the triangle are n, 4n−2, and 4n−4, what is the length of each side?

Answers

Answer:

6; 22; 20 (ft.)

Step-by-step explanation:

1) if the length of the each side are: n; 4n-2 and 4n-4, then the expression of the perimeter can be written: P=n+4n-2+4n-4 or P=9n-6.

2) if according to the condition perimeter is 48 (ft.), then

9n-6=P; ⇔ 9n-6=48; n=6.

3) if n=6, then the required lengths of the sides are:

n=6 (ft.);

4n-2=22 (ft.);

4n-4=20 (ft.)

Find the area of this figure. Round your answer to the nearest hundredth. Use 3.14 to approximate

Answers

Step-by-step explanation:

Area of a Triangle:

bh/2

8 ft is the given height

6 ft is the given base (or width)

(8)(6)/2

48/2

= 24 ft²

In addition to this, we will have to find the area of the semicircle.

Area of a Semicircle:

πr²/2

The question tells us to use 3.14 in place of π.

3.14r²/2

The diameter is 8 ft as it is given to us in the diagram, but in the formula we would have use the radius, and because the radius ia half of the diameter we will divide 8 by 2.

8/2

= 4

3.14(4)²/2

Solve...

3.14(16)/2

50.24/2

= 25.12 ft²

Now that we have found the area of both the triangle and the semicircle, we can add them together to find the area of the figure.

24 ft² + 25.12 ft²

= 49.12 ft²

Our final answer is A=49.12 ft² because it is already in the hundredths place.

C. -36
D. 1/36

Answers

Answer:

Positive 1 over 6 raised to the 2nd power 1/62 or 1 over 36 which is 1/36. To find -6-2, take the inverse of -62.

(first find -62) -62 = -6 * -6 = 36

(then take the inverse of 36, which is 1 over 36) = 1 / 36 = 0.0277

so, -6-2 =0.0277

Step-by-step explanation:

There are 5 red marbles out of 8.

P(r1) = 5/8

Now we have 7 total marbles and 4 of them are red.

The probability of the second red:

P(r2) = 4/7

Find the sides of a rectangle whose area is given as x2 +15x +56.

Answers

(x+7) (x+8) so the sides of the rectangle is 7 and 8

x^2 + 15x + 56

Good way to factor quadratic functions:

In a function x^2 +bx + c

Find two number that when multiplied together will form c (in our case 56) and that when added together form b (in our case 15)

Number 1 x Number 2 = 56

Number 1 + Number 2 = 15

Number 1 = 8

Number 2 = 7

(It'll be easier to find these numbers with practice)

Now in the function instead of bx, split it and use (number 1)x + (number 2)x

It's allowed because it's the same value since N1 + N2 = bx already

x^2 + 15x + 56

Now is:

x^2 + 8x + 7x + 56

Now you can factor this function much easily because it can transformed into:

(x + 8)(x) + (x + 8)(7)

x + 8 is the common factor

it can become:

(x + 8) (x + 7)

The sides of the rectangle are 8 and 7

Hope this helps you with factoring :)

(28-31 in the picture)

Answers

Answer:

28. 120 degrees

29. 30 degrees

30. 56 degrees & 124 degrees

31. 72 degrees, 108 degrees, and 18 degrees

Step-by-step explanation:

We assign variable x for the answer we are looking for (28-29).

28.

Supplement means x + y = 180 degrees. We also know x = 2y. Substitution gives us 3y = 180 degrees, so y = 60 degrees and x = 120 degrees.

29.

Complement means x + y = 90 degrees. We are given 2x = y. Substitution brings us 3x = 90 degrees, x = 30 degrees.

30.

Supplement means x + y = 180 degrees. We are told that y = 2x + 12, so we substitute. This gives 3x + 12 = 180 degrees, x = 56 degrees. Substituting that back into the equation for y, we get 124 degrees.

31.

Supplement means x + y = 180 degrees. Complement means x + z = 90 degrees.  Using our given info, we know y = 6z. We can substitute that in to get x + 6z = 180. Subtracting our second and third equations, we get 5z = 90, z = 18 degrees.  Therefore, x = 72 degrees, y = 108 degrees.
