If BC = 3x, CD = 7x, and BD = 10, what is BC?

Answers

Answer 1

Answer:

BC= 3

Step-by-step explanation:

Suppose a line BD is 10 and it has a point C somewhere on the  line. It is given that BC is  3times and CD is 7 times  or algebraically  if we take x as a variable then according to the given information

BC+ CD= BD

3x+ 7x= 10

10x= 10

x= 10/10

x= 1

3x would give 3 (1)= 3

Hence the Line BC = 3

and the line CD= 7

If BC = 3x, CD = 7x, And BD = 10, What Is BC?

Step-by-step explanation:

We can solve using proportions.

[tex] \frac{9 \: laps}{27 \: minutes} = \frac{20 \: laps}{x} \\ \\ \frac{540}{9} = \frac{9x}{9} \\ \\ 60 = x[/tex]

What pair of points have a slope of -3/5

Answers

Answer:

(5,0) and (0,3) have a slope of -3/5

Step-by-step explanation:

Here, we want to state a pair of points that have a slope of -3/5

Mathematically, we can have the slope of a straight line calculated as;

m = y2-y1/(x2-x1)

This could give points like (5,0) and (0,3)

The X coordinate of a point P on X axis is 4 and the y coordinate of a point Q on y axis is 3. Find the distance of PQ.​

Answers

Answer:

5 units

Step-by-step explanation:

Since The X coordinate of a point P on X axis is 4 and the y coordinate of a point Q on y axis is 3 the points are

P (4 , 0) and Q(0 , 3)

The formula to calculate distance between two points

[tex]PQ=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\PQ=\sqrt{(0-4)^2+(3-0)}\\PQ=\sqrt{(4)^2+(3)^2}\\PQ=\sqrt{16+9} \\PQ=\sqrt{25} \\PQ=5\ units\ \\[/tex]

IMPORTANT!

As we take the square root of 25 we get two values +5 and -5 we always take the positive value because distance can never be negative.

Step-by-step explanation:

Given: g(x) = Vx – 4 and h(x) = 2x – 8.
What is g(h(10))?

Answers

Answer:

g(h(10)) = 43

Step-by-step explanation:

Given: g(x) = 4x – 4 and h(x) = 2x – 8.

We are to find g(h(10))

First we need to get g(h(x))

g(h(x)) = g(2x-8)

Replace x in g(x) with 2x-8 as shown:

g(2x-8) = 4(2x-8)-4

g(2x-8)= 8x-32-5

g(2x-8) = 8x-37

Hence g(h(x)) = 8x-37

g(h(10)) = 8(10)-37

g(h(10)) = 80-37

g(h(10)) = 43

Hence g(h(10)) is 43

"A number x increased by 6, and then doubled."
A)
2x + 6
B
B)
2x - 6
2(x + 6)
D)
246 - x)

Answers

Answer:

(X + 6 ) ×2

It is given in the question that the no. is increased by 6 so if we take the no. as X the new no. formed is X + 6 now on doubling it the answer we get is. 2(X+6)

The correct algebraic expression is option C) 2(x + 6) matches the expression that represents the number x increased by 6, and then doubled.

Given that : "a number x increased by 6, and then doubled," perform the operations in the correct order.

To represent the given scenario of "a number x increased by 6, and then doubled," required to follow the steps:

Step 1:

Let the number be x.

Increase the number x by 6:

x + 6.

Step 2 :

Double the result by multiply the expression:

(x + 6)2,

Remove brackets by BODMASS gives:

2* x + 2 *6

On multiplying gives:

2x+12

ON taking common factors 2 gives:

2(x+6)

Therefore, the correct expression is 2(x + 6).

Option C) 2(x + 6) matches the expression that represents the number x increased by 6, and then doubled.
