Answer:

the answer is 3,680

Step-by-step explanation:

Answer:

from 0 to t1

Airplane A travels at a speed that is increasing.

Airplane B travels at a speed that is constant but not 0.

from t1 to t2

Airplane A travels at a speed that is  constant, but not 0

Airplane B travels at a speed that is  0.

The airplane A is travelling at a faster and faster rate from 0 to t₁, and airplane B moves at a steady but not zero speed from 0 to t₁

A line graph is a graph made up of segments of straight lines that connect the depicted data points.

We have a graph for Airplane A shows the speed at which it travels as a function of time. The graph for Airplane B shows the distance it travels as a function of time.

From the graph A and B

From 0 to [tex]\rm t_1[/tex]

Airplane A is travelling at a faster and faster rate.

Airplane B moves at a steady but not zero speed.

From [tex]\rm t_1[/tex] to [tex]\rm t_2[/tex]

Airplane A moves at a constant speed, but not at zero.

Airplane B is travelling at a speed of 0.

Thus, the airplane A is travelling at a faster and faster rate from 0 to t₁, and airplane B moves at a steady but not zero speed from 0 to t₁

Answer:

• Let's first assign identifications to the equations given:

[tex]{ \rm{8x + 9y = {}^{ - }3 \: - - - \{equation \: (a) \} }} \\ { \rm{6x + 7y = 1 - - - \{equation \: (b) \}}} \\ [/tex]

• There are various methods to solve this system of equation, namely;

1. Graphical method

→ You'll have to draw a graph, demacate it very well following the suitable scale.

→ Get values to plot from both equation (a) and equation (b).

→ Draw respective lines of each equation. The point of intersection of the lines is the answer of the values of x and y.

→ It'll be in coordinate format i.e; (x, y)

2. Substitution method

→ Lemme first consider equation (a)

[tex]{ \rm{8x + 9y = {}^{ - }3 }}[/tex]

• make x the subject of the equation (a):

[tex]{ \rm{8x = - 3 - 9y}} \\ \\ { \rm{x = \frac{ - 3}{8} - \frac{9}{8}y }} \: { \rm{- - - \{equation \: (c)}} \}[/tex]

→ Considering equation (b) next

[tex]{ \rm{6x + 7y = 1}}[/tex]

• substitute x in equation (b) with x in equation (c)

[tex]{ \rm{6( \frac{ - 3}{8} - \frac{9}{8}y ) + 7y = 1 }} \\ \\ { \rm{ - \frac{9}{4} - \frac{27}{4} y + 7y = 1}} \\ \\ { \rm{ \frac{1}{4} y = \frac{13}{4} }} \\ \\ { \underline{ \rm{ \: \: y = 13 \: \: }}}[/tex]

• then find x using equation (c)

[tex]{ \rm{x = \frac{ - 3}{8} - \frac{9}{8} y }} \\ \\ { \rm{x = \frac{ - 3}{8} - \frac{9}{8} (13)}} \\ \\ { \underline{ \rm{ \: \: x = - 15 \: \: }}}[/tex]

3. Elimination method:

→ Here, we have to align the equations so that if we use addition or subtraction operations we remain with one term giving us zero [ eliminated ]

→ Multiply equation (a) by 6 and multiply equation (b) by 8. In order to eliminate x

→ Then we subtract equation (a) with equation (b)

[tex]{ \underline{ \rm{ - \binom{6(8x + 9y = - 3)}{8(6x + 7y = 1)} }}} \\ { \rm{ 0x \: - 2y = - 26 }} \\ \\ { \rm{ - 2y = - 26}} \\ \\ { \underline{ \rm{ \: \: y = 13 \: \: }}}[/tex]

• find x using equation (c)

[tex]{ \rm{x = \frac{ - 3}{8} - \frac{9}{8} y}} \\ \\ { \underline{ \rm{ \: \: x = - 15 \: \: }}}[/tex]

4. Calculator synthetic method:

→ To use this method, you must have a scientific calculator.

→ If you have it, follow the steps below;

Answer:

18

Step-by-step explanation:

Let the number be x.

1/3 of itself is 1/3 x or x/3.

x = x/3 + 12

3x/3 - x/3 = 12

2x/3 = 12

3/2 * 2x/3 = 3/2 * 12

x = 18

Answer: 18

The equation is formed as x - x/3 = 12. Then the solution of the equation will be 18.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The number is 12 more than 1/3 of itself.

Let the number be 'x'. Then the equation is written as,

x = x/3 + 12

Simplify the equation, then the value of 'x' will be calculated as,

x - x/3 = 12

3x - x = 36

2x = 36

x = 36/2

x = 18

The equation is formed as x - x/3 = 12. Then the solution of the equation will be 18.

Answer:

lx-24l ≤ 8

Step-by-step explanation:

lx-24l ≤ 8

x ≤ 8 + 24

x ≤ 32

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

-x + 24 ≤ 8

24 - 8 ≤ x

16 ≤ x

The absolute value equation that represents the minimum and maximum lengths is 8 = |x - 24|.

Absolute value is defined as the magnitude or size of a number, no negatives are allowed. The distance a number is from 0 on the number line is known as the absolute value of the number.  

For example, |5| is 5 because it is 5 units away from 0.  Also, |-5| is also 5 because -5 is 5 units from 0.

We have been given that for a poetry contest the minimum length of a poem is 16 lines. The maximum length is 32 lines.

To determine the absolute value equation that represents the minimum and maximum lengths.

First,  we need to find the difference between both solutions.

⇒ 32 - 16 = 16

Then, divide it by 2.

⇒ 16/2 = 8

⇒ 8 = |x - 32 + 8|

we could also write: 8 = |x - 32 + 8|

⇒ 8 = |x - 24|

Therefore, the absolute value equation that represents the minimum and maximum lengths is 8 = |x - 24|.

The length of a rectangle is four times its width.

If the perimeter of the rectangle is 70 ft,

let the width =x

length =4width=4x

According to the question,

the perimeter of the rectangle is 70 ft

Therefore:-

Sum of the exterior angles of a pentagon = 360

              ⇒   115 + 2x + 3x + x + x = 360      

                                   [simplify the x terms and subtract 115 from both sides]

                                                  7x = 360 - 115   [divide both sides by 7]

brainliest and follow please

let the interior angles of the given triangle be angle a b c respectively.

116+a=180 (Sum of angles on a straight line.)

a=180-116

a=64

.......

112+b=180(Sum of angles on a straight line.)

Sum of angles on a straight line.)b=180-112

b=68

....

angle a +b+c=180 (Sum of angles of a triangle)

64+68+c=180

c=180-132

c=48

.,....

angle c +X =180(Sum of angles on a straight line.)

48+X=180

X=132

Therefore the value of X is 132.

2.

solution,

Let the remaining interior angle of the given triangle be y.

Then,

y+108=180(Sum of angles on a straight line.)

y=72

Again,

2x+X+y=180(Sum of angles of a triangle)

3x+72=180

3x=108

X=108÷3

X=36

Therefore the value of X is 36.

3.

solution,

let the remaining interior angle of the given polygon be a and b .

Then,

100+b=180(Sum of angles on a straight line.)

b=80

......

Again,

a+b+110+90=360(Sum of interior angle of the polygon)

a+80+200=360

a+280=360

a=80

.....

a+X=180(Sum of angles on a straight line.)

80+X=180

X=100

Therefore the value of X is 100.

4.

solution,

The given triangle is an isosceles triangle.So their base angles are equal .

43+43+X=180(Sum of angles of a triangle)

X=180-86

X=94

Therefore the value of X is 94.

5.

solution,

Opposite angles of a parallelogram is equal

So ,

X=125

Therefore the value of X is 125.

6.

solution,

Let the remaining interior angle of the triangle be a .

Then,

a+117=180 (Sum of angles on a straight line.)

a=63

Now,

a+X+83=180(Sum of angles of a triangle)

63+83+X=180

146+X=180

X=34

Therefore ,the value of X is 34.

Answer:

y = x² - 6x + 9

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k ) = (3, 0 ) , then

y = a(x - 3)² + 0

To find a substitute (1, 4) into the equation

4 = a(1 - 3)² = a(- 2)² = 4a ( divide both sides by 4 )

1 = a

y = (x - 3)² = x² - 6x + 9

Step-by-step explanation:

At first find two numbers, that if you multiply, you get +15x², and the same number, if you do addition, get -8x

Those numbers are: -5x and -3x.

Now replace the -8x with the -5x and -3x. (x² - 5x - 3x + 15)

Now factorise as normal. You should get (x-5) and (x-3)
