Answer:

yes.

Step-by-step explanation:

D.   a = ( y - k ) / ( x - h )^2

y = a ( x - h )^2 + k

=> y - k = a ( x - h )^2

=> ( y - k ) / ( x - h )^2 = a

the answer is x8

Answer:

y = -2x

Step-by-step explanation:

The appropriate "direct variation" rule (formula) is y = kx.

Since y = 4 when x = -2, 4 = k(-2), or k = -2

Then the specific formula relating x and y is y = -2x

Answer:

m = 7

Step-by-step explanation:

2(m + 2) = 18

the first step is to distribute the 2 so we don't have parenthesis

2 x m = 2m and 2 + 2 = 4

now we're left with 2m + 4 = 18

we want to get m alone on one side so we have to subtract 4 from both sides

2m + 4 = 18

       -4    -4

we are left with 2m = 14

the last step is to divide and since we want m alone, we have to divide 2 from both sides

2m/2 = m

14/2 = 7

so m = 7

If you are asking for the total land surface but if you are asking for the total including the water it is, 196.9 million mi²

Answer:

150 million square kilometres and 51 million square kilometres

Step-by-step explanation:

1. 15 million square kilometres is approximately 10% of the world's land surface and the total land surface of the world is 100%, so we can multiply 15 million km² by 10 to get 100% which is 150 million km².

2. 34% of the world's land surface is covered by some form of desert so we would have to find 34% of 150 million km² which is 51 million km² (150 million × 0.34)

Answer:

100.8 cm

Step-by-step explanation:

Area of square= side * side

let,

side=x

Substitute values in above formula:

635 [tex]cm^{2}[/tex]=x*x

[tex]x^{2}[/tex]=635 [tex]cm^{2}[/tex]

Taking square root on both sides:

x=25.2cm

side=25.2cm

Now, Permiter=4* side

Perimeter=4*25.2cm

Perimeter=100.8 cm

Answer:

The base angles of an isosceles triangle are the angles formed by the base and one leg of the triangle. The base angles theorem converse states if two angles in a triangle are congruent, then the sides opposite those angles are also congruent.

In an isosceles triangle that has exactly two equal sides, the equal sides are called legs and the third side is called the base.

Two polygons are congruent if their corresponding sides and angles are congruent. Note: Two sides are congruent if they have the same length and angles are congruent if they have the same measure. Congruent polygons necessarily have to have the same shape and the same size.

Congruent triangles are triangles that have the same size and shape. This means that the corresponding sides are equal and the corresponding angles are equal. We can tell whether two triangles are congruent without testing all the sides and all the angles of the two triangles.

corollary is a proposition that follows from (and is often appended to) one already proved.

In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.

Legs of a Right Triangle. The legs of a right triangle are the two sides that intersect to determine the right angle. The remaining side is called the hypotenuse. Sometimes it is required to solve a right triangle to find the length of one or both of the legs of the right triangle.

The equal sides of an isosceles triangle are known as the 'legs.' The third and unequal side of an isosceles triangle is known as the 'base. The angles situated opposite to the equal sides of an isosceles triangle are always equal.

Every triangle has 180 degrees. An isosceles triangle has one vertex angle and two congruent base angles. Thus, 65 is the base angle and 50 is the vertex angle.

Answer:

Vertex is the answer they are correct

Step-by-step explanation:

(i)

that is really simple. for each point go vertically and horizontally to the x and y axis and see at what numbers you hit the axis.

A is -2 on x and +3 on y. so, it's coordinates are (-2, 3).

B is (4, 6).

(ii)

the gradient is also called the slope. it describes the "tilt" of the line.

the gradient or slope is expressed as ratio y/x indicating how many units y changes, when x changes a certain amount of units when going from one point to another.

from (-2, 3) to (4, 6) :

x changes by +6 units (from -2 to 4).

y changes by +3 units (from 3 to 6).

so, the gradient/slope = 3/6 = 1/2

(iii)

the general line equation is

y = ax + b

a is the gradient/slope and is always the factor of x.

b is the y-intercept (the y value when x = 0, meaning the point the line crosses the y-axis).

we have already the gradient or slope.

we get b either by reading that point from the chart (it looks like (0, 4)) or by using the coordinates of one of the known points as x and y values in the equation and solve for b. I just picked (4, 6) :

6 = (1/2)×4 + b = 2 + b

b = 4

hey, we were right before !

so, the full line equation is

y = (1/2)x + 4 or simple x/2 + 4

Answer:

b

Step-by-step explanation:

6/2 = 3

because the triangle is halved

use pythagorus 3²+4²=25

√25 = 5

so x=5

Answer:

yes

Step-by-step explanation:

1, 7, 13, 19, 25, ...

a = 1

common difference = d = 7 - 1 = 6

13 - 7 = 6

nth term is

a(n) = a + (n - 1)d

= 1 + (n - 1)6

= 1 + 6n - 6

= 6n - 5

6n - 5 = 331

6n = 331 + 5

6n = 336

n = 56

as n is an integer

331 is 56th term

Answer:first one infinently

Step-by-step explanation:

The solution of the equation are:

1. 6(x-3)+4x=5(2x-4)-2 → No solution.

2. 2 − 6 − 3 = 5 − (4 + 2) → No solution.

3. 6(x - 2) + 8 = 3(2x - 4) → No solution.

4. 4x + 8 - 6x + 12 = 3(x + 7) - 5x - 1 → One solution.

1. 6(x-3)+4x=5(2x-4)-2

Step 1: Distribute the numbers outside the parentheses:

[tex]\(6x - 18 + 4x = 10x - 20 - 2\)[/tex]

Step 2: Combine like terms:

[tex]\(10x - 18 = 10x - 22\)[/tex]

Step 3: Isolate the variable on one side:

10x - 10x = -22 + 18

0 = -4

The equation 0 = -4 is not true.

It means that the variable x has canceled out, and both sides of the equation are not equal.

So, there is no solution for this equation.

2. 2 − 6 − 3 = 5 − (4 + 2)

Step 1: Perform operations inside parentheses and simplify:

2 - 6 - 3 = 5 - 6

Step 2: Continue simplifying:

-7 = -1

The equation -7 = -1 is not true.

So, there is no solution for this equation.

3. [tex]\(6(x - 2) + 8 = 3(2x - 4)\)[/tex]

Step 1: Distribute the numbers outside the parentheses:

[tex]\(6x - 12 + 8 = 6x - 12\)[/tex]

Step 2: Combine like terms:

6x - 4 = 6x - 12

Step 3: Isolate the variable on one side:

6x - 6x = -12 + 4

0 = -8

The equation 0 = -8 is not true.

So, there is no solution for this equation.

4. [tex]\(4x + 8 - 6x + 12 = 3(x + 7) - 5x - 1\)[/tex]

Step 1: Combine like terms on each side of the equation:

-2x + 20 = 3x + 20 - 1

Step 2: Continue simplifying:

-2x + 20 = 3x + 19

Step 3: Isolate the variable on one side:

-2x - 3x = 19 - 20

-5x = -1

Step 4: Solve for x:

[tex]\(x = \dfrac{-1}{-5} = \dfrac{1}{5}\)[/tex]

The equation  [tex]x = \dfrac{1}{5}[/tex] is true, which means that the variable x has a unique value that satisfies the equation.

So, there is one solution for this equation.

Answer:

120 Yards

Step-by-step explanation:

42 feet is equal to 14 yards.

So if 14 yards is walked in 7 seconds then 2 yards are walked in 1 second.

So if 2 yards are walked in 1 second and there are 60 seconds in a minute, then 120 yards are walked in one minute.

So the answer is 120 yards.
