Answer:

slope = [tex]\frac{12}{7}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 7, - 8) and (x₂, y₂ ) = (0, 4)

m = [tex]\frac{4+8}{0+7}[/tex] = [tex]\frac{12}{7}[/tex]

Step-by-step explanation:

6=2(y+2)

Distribute 2

6=2y+4

-4    -4

2=2y

______

2

y=1

Answer:

y = 1

Step-by-step explanation:

First, you need to use the distributive property to simplify:

6 = 2y + 4

Then, subtract 4 from both sides, so you get the numbers on one side and the variables on the other.

2 = 2y

Divide both sides by 2, and . . .

y = 1

Answer:

2 hours

Step-by-step explanation:

Distance = Rate * Time

If we replace these with the numbers in the problem and use "t" as the variable, it becomes:

30 miles = 15 mph * t

Now, to solve:

30 = 15t

divide both sides by 15

t = 2

add the units

time = 2 hours

Answer:

a). Perimeter = (5r + 9) cm

b). r = 8

Step-by-step explanation:

Property of isosceles triangle:

- Two sides of an isosceles triangle are equal.

- Opposite sides of the equal angles are equal in measure.

  From the figure attached,

  PQ = QR = (2r + 3)

a). Since perimeter of a polygon = sum of all sides of the polygon

                                                 = PQ + QR + PR

                                                 = (2r + 3) + (2r + 3) + (r + 3)

                                                 = 5r + 9

    Perimeter of the given triangle = (5r + 9) cm

b). Perimeter of the given triangle = 49 cm

    (5r + 9) = 49

     5r = 40

      r = 8

Answer:

28 ft

Step-by-step explanation:

Since the shadows were cast at the same time of the day, both triangular images formed would be similar to each other.

Therefore, the ratio of their corresponding sides would be equal.

That is, the height of the tree / the height of the alien = the shadow of the tree / the shadow of the alien

Height of the tree = x ft

Height of the alien = 7 ft

Shadow of the tree = 48 ft

Shadow of the alien = 12 ft

Plug in the values into the proportional equation stated earlier.

Thus, the ratio of their corresponding sides would be:

[tex] \frac{x}{7} = \frac{48}{12} [/tex]

Cross multiply

[tex] x*12 = 48*7 [/tex]

[tex] 12x = 336 [/tex]

Divide both sides by 12

[tex] x = \frac{336}{12} [/tex]

[tex] x = 28 [/tex]

The height of the tree = 28 ft

Answer:

slope is m = 2

Answer:

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]

From the question we have

[tex]m = \frac{ - 5 - 5}{ - 3 - 2} = \frac{ - 10}{ -5 } = \frac{10}{5} = 2\\ [/tex]

Answer:

I have not come across this particular mathematical topic lol. Social media influences people and people influence government. Unless you leave in a non-democracy, the government cares about public opinion to some extent.

Step-by-step explanation:

What is the equation of the line that is parallel to the

given line and passes through the point (-2, 2)?

O y = x +4

O y = kx + 12

O y=-5x + 4

O y = -5x + 12

The result of five ninths minus two sixths is two - ninths.

Let us first write the words in figures so that we can perform the required calculation;

five ninths = 5/9

two sixths = 2/6

This means that we are simply asked to subtract 5/9  from 2/6

Hence;

5/9 - 2/6, we have to take LCM. The LCM of 5/9 and 2/6 is 18. The term LCM actually means lowest common multiple of 9 and 6.

So;

[tex]\frac{10 - 6}{18} = \frac{4}{18} = \frac{2}{9}[/tex]

8^6 ÷ 4^3

8^6 = 262,144

4^3 = 64

So, 262,144 ÷ 64 = 4,096.

Done!

Answer:

2^12 = 4096

Step-by-step explanation:

Assuming that the problem is:

8^(6) / 4^(3)

1. Convert all numbers to the same base

In other words, rewrite the problem such that all the bases (the numbers under the exponent) are the same.

8 can be rewritten as 2^3

4 can be rewritten as 2^2

Hence the problem is:

((2^(3))^(6)) / ((2^(2))^(3))

2. Combine the exponents on the numerator and denominator

((2^(3))^(6)) / ((2^(2))^(3))

Simplify, remember an exponent to the power of another exponent is the same as multiplying the two exponents, applying this:

(2^(18)) / (2^(6))

3. Simplify the fraction and solve

(2^(18)) / (2^(6))

Dividing two exponents, with the same base is the same as subtracting the exponents, hence:

(2^(12))

= 4096

Answer:

v=5

Step-by-step explanation:

you are trying to make 4v into v right ?

so simply divide it by 4 - the same if it was 4a or 7a or 9k, always start by dividing by the number

then you need to balance the two sides - so whatever number you divide the letter by (which is the 4 in this case) , you do the same with the other side , so whatever number is after the equal sign , divide it by 4

PART ONE                                      ↓ 4v  =   20  

           DIVIDE BY 4                       →  v   =    20

PART TWO                                          v   =   20 ↓

                                                            v   =     5 ←           DIVIDE BY 4

Answer:

y - intercept = 8

Step-by-step explanation:

Given

y = (m - 2)(m - 4)

To find the y- intercept, let m = 0 in the equation and solve for y, that is

y = (0 - 2)(0 - 4)

  = (- 2)(- 4)

  = 8 ← y- intercept or in coordinate form as (0, 8 )

Answer:

i am pretty sure :)

Answer:

d=rt is basically y=mx+b but with different variables. B is where the line intercepts the y axis and since this line intercepts at 0, 0 b can automatically be deleted from the equation. therefore d=rt is equivilent to y=mx

The slope is 6. I know this by looking at the first point of the line (0, 0) and finding the next point on the line (1, 6). To get from 0, 0 to 1,6 you need to go up 6 and over 1. Since rise/run is the slope of a line 6/1 or 6 is the slope.

At 1, 6 we see that in 1 hour, joseph went 6 miles. Therefore the constant rate is 6 miles per hour (6 mp/h.)

The slope, already found, is 6 and therefore if d=rt is equivilent to y=mx we can write our equation as d=6t

6 mp/h

d=6t
