find the value of x and y​

Answer:

BD measures 20 units.

Step-by-step explanation:

We are given that Point C is on the line segment BD, where:

[tex]BD = 5x, BC = 4x \text{ and } CD = 4[/tex]

And we want to determine the numerical length of BD.

Since C is somewhere on BD, BD is the sum of BC and CD:

[tex]\displaystyle BD = BC + CD[/tex]

Substitute:

[tex](5x) = (4x) + (4)[/tex]

Solve for x. Subtract:

[tex]x = 4[/tex]

Hence, the value of x is 4.

BD is given by 5x. Therefore:

[tex]BD = 5(4) = 20\text{ units}[/tex]

In conclusion, BD measures 20 units.

Answer: 6m+4n=32

Step-by-step explanation:

m=4

n=2

From this, we can deduce that m+n=32.

6*4=24 and 4*2=8. 24+8=32

So, 6m+4n=32. Hope this was what you were looking for!

Answer:

[tex]s = \frac{9± \sqrt{ - 39} }{4} [/tex]

Step-by-step explanation:

[tex] \frac{3(s - 5)}{4 - 3} = \frac{4s \times (s - 3)}{2} [/tex]

➡️ [tex] \frac{3(s - 5)}{1} = 2s \times (s - 3)[/tex]

➡️ [tex]3s - 15 = 2 {s}^{2} - 6s[/tex]

➡️ [tex]3s - 15 - 2 {s}^{2} + 6s = 0[/tex]

➡️ [tex]9s - 15 - 2 {s}^{2} = 0[/tex]

➡️ [tex] - 2 {s}^{2} + 9s - 15 = 0[/tex]

➡️ [tex]2 {s}^{2} - 9s + 15 = 0[/tex]

➡️ [tex]s = \frac{ - ( - 9)± \sqrt{( - 9 {)}^{2} - 4 \times 2 \times 15} }{2 \times 2} [/tex]

➡️ [tex]s = \frac{9± \sqrt{81 - 120} }{4} [/tex]

➡️ [tex]s = \frac{9± \sqrt{ - 39} }{4} [/tex]

➡️ [tex]s∉ℝ[/tex]

Answer

(3.5 times 5.25) times 4

Step-by-step explanation:

then convert the decimal to a fraction.

We have that The height as a linear function of time is

[tex]x=-27.5T+500[/tex]

From the Question we are told that

Time t=8 minutes

Height h=500

Descended height h_d= 280 feet.

Generally the equation for the linear function  is mathematically given as

Let

Height as a linear function =x

[tex]x=\frac{h_d-h}{t}*T+h[/tex]

[tex]x=\frac{280-500}{8}*T+500[/tex]

[tex]x=-27.5T+500[/tex]

In conclusion

The height as a linear function of time is

[tex]x=-27.5T+500[/tex]

Answer:

b = 10

Step-by-step explanation:

Expand the left side and compare the coefficients of like terms

(2x + a)(4x - 1) ← expand using FOIL

= 8x² + 4ax - 2x - a = 8x² + x(4a - 2) - a

Compare coefficients of like terms with

8x² + bx - 3

Then a = 3 ( constant term )

b = 4a - 2 ( coefficients of the x- term )

b = 4(3) - 2 = 12 - 2 = 10

Answer:

b = 10

Step-by-step explanation:

We can break those parenthesis like this

[tex](2x + a)(4x - 1) \\ = 2x(4x - 1) + a(4x - 1) \\ = 8{x}^{2} - 2x + 4ax - a[/tex]

And then combine the terms end with x we get

[tex]8 {x}^{2} - 2x + 4ax - a \\ = 8 {x}^{2} + 4ax - 2x - a \\ = 8 {x}^{2} + (4a - 2)x - a[/tex]

Now by comparing 2 expressions, we can see that a is 3, and b = 4a-2 = 12-2 = 10

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.p explanation:

Q.3 It takes 490 seconds for light to get from the sun to the earth should light travel at the above-mentioned speed.

Answer:

50

Step-by-step explanation:

x + 30 = 180 - 2x   [vertically opposite angles]

x = 180 - 30 - 2x

x = 150 - 2x

x + 2x = 150

3x = 150

x = 150/3

x = 50

Answer:

48

Step-by-step explanation:

In this problem, you need to find out how many total legs 8 ants would have together. Each ant has 6 legs; this means that to solve you must add 6 together 8 times. However, there is an easier way to do this. You can also multiply 6 by 8 to get the same answer. The answer is 48.

Answer:

they would each get 6 and there would be 2 left over

Step-by-step explanation:

3x6=18

20-18=2

=2 leftovers

Answer:

Each of the friends will get 6 with 2 small prizes remaing

Step-by-step explanation:

20 ÷ 6 = 18 remainder of 2

Ignore the 2 because you cannot split 2 evenly from 3 people.

So each friend gets 6, while there is a 2 remainder

To check our work just do 6 × 3 = 18 and 20 - 18 = 2

So, in conclusion, each friend get 6 while there are 2 small prizes left

Step-by-step explanation:

(16-8)x(2+4)

= 8x(6)

= 8x6

= 48
