         What is the S.I. form of the equation that passes through (-6,3) and is parallel to y=2x-3?

[tex]\diamond\large\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}[/tex]

    Parallel lines have the same slope.

[tex]\bigstar[/tex] The line y=2x-3 has a slope of 2, therefore, the line parallel to it has a slope of 2.

Now let's write the equation of the new line in point-slope form:-

[tex]\sf{y-y_1=m(x-x_1)}[/tex]

Replace y1 with -3, m with 2, and then write -6 in lieu of x1:-

[tex]\sf{y-(-3)=2(x-(-6)}[/tex]

On simplification,

[tex]\sf{y+3=2(x+6)}[/tex]

On further simplification,

[tex]\sf{y=2x+12-3}[/tex]

Which results in:-

[tex]\sf{y=2x-9}[/tex]

Answer:

12

Step-by-step explanation:

22n + 17(20 - n) = 400 ← distribute parenthesis and simplify left side

22n + 340 - 17n = 400

5n + 340 = 400 ( subtract 340 from both sides )

5n = 60 ( divide both sides by 5 )

n = 12

The length of the side DA from secant theorem is; 10

From the cyclic diagram attached;

Since CA = 12.5 and CB = 4.5, it means that;

BA = 12.5 - 4.5 = 8

From the secant theorem, we know that;

The product of the secant and its exterior segment is equal to the square of the tangent segment.

Thus;

Length of DA = √(8 * 12.5)

Length of DA = 10

The conditional probabilities that are correct are P(D | F) =  6/34, P(E | D) = 7/25 and P(F | E) = 8/18

The formula to compute the conditional probability P(A|B) is:

P(A | B) = P(A and B)/P(B)

The above means that the probability of event A such that the event B has already occurred

When the above formula is applied to the give data in the complete, we have:

P(D | F) = 6/34

P(E | D) = 7/25

P(D | E) = 7/18

P(F | E) = 8/18

P(E | F) = 8/34

Hence, the conditional probabilities that are correct are P(D | F) =  6/34, P(E | D) = 7/25 and P(F | E) = 8/18

A function assigns the value of each element of one set to the other specific element of another set. The number of centenarians in the country in 2013 is 9.4175×10⁴⁵.

A function assigns the value of each element of one set to the other specific element of another set.

The exponential function that can be used to project the number of centenarians in a certain country is [tex]H(t) = 80,030.83(1.0481)^t[/tex].

Now, the number of centenarians in the country in 2013 is,

[tex]H(t) = 80,030.83(1.0481)^t\\\\H(2013) = 80,030.83(1.0481)^{2013}\\\\H(2013) = 9.4175 \times 10^{45}[/tex]

Also, the number of centenarians in the country in 2038 is,

[tex]H(t) = 80,030.83(1.0481)^t\\\\H(2038) = 80,030.83(1.0481)^{2038}\\\\H(2038) = 3.048 \times 10^{46}[/tex]

Step-by-step explanation:

m(arc)JL = 2 × 49° = 98°

m(arc)MJ = 360° - 120° - 98° = 142°

m<KJM = (120° + 46°)/2 = 83°

Answer:

No, this isn't a right triangle.

Step-by-step explanation:

To check if the triangle is right we can use Pythagorean Theorem. If the equation turns out as true, the triangle is right.

Pythagorean Theorem

[tex]c^2 = a^2 + b^2[/tex]

c ... hypotenuse

a ... one leg

b ... another leg

The longest side in a right triangle is always hypotenuse, therefore we use the side which is 13 cm long as hypotenuse.

[tex]c^2 = a^2 + b^2\\13^2 = 4^2 + 12^2\\169 = 16 + 144\\169 = 160[/tex]

Number 169 isn't equal to 160 so the equation is false. That means that the triangle is not right.

Step-by-step explanation:

9 + 4 + 7 = 20

1 out of 20 = 5%

4 plums = 20%

Answer:

4/5 or 80%

Step-by-step explanation:

So u add up all the fruits which is 20. And then then u make a fraction which is all fruits but not plums over all fruits. So it is 16/20. The 16 came from not having the plums bc there are 4 plums and 20 - 4 = 16. Simplified of 16/20 is 4/5 or %80.

Step-by-step explanation:

The expected number of flips from that point until the number of heads flipped in total equals the number of tails is 2

The given parameters are:

P(Head) = 70%

The expected number of flipping a head is:

E(x) = 70% * x

The expected number of flipping a tail is:

E(x) = (1 - 70%) * x + 1

Where 1 represents the first flip

When both values are equal, we have:

70% * x = (1 - 70%) * x + 1

Evaluate

0.7x = 0.3x + 1

Evaluate the like terms

0.4x = 1

Divide both sides by 0.4

x = 2.5

Remove the decimal

x = 2

Hence, the expected number of flips from that point until the number of heads flipped in total equals the number of tails is 2

Step-by-step explanation:

No integer ratio with 8 in the denominator can be equal to any integer ratio with 3 in the denominator.

The denominators 8 and 3 are relatively prime, so equivalent fractions using them cannot be formed with integers.

The equivalent to 4/3 has a mixed-number numerator that is greater than 8.

  x² = 65² -56² = 4225 -3136 = 1089

  x = √1089 = 33
