Answer:

B

Step-by-step explanation:

We know that AB has endpoints at A(4, -3) and B(3, 7).

To find Line D, which is the perpendicular bisector of AB, we first need to find the slope of AB and its midpoint.

So, let's find the slope of AB using the slope formula:

Let (4, -3) be (x₁, y₁) and let (3, 7) be (x₂, y₂). Substitute them into the slope formula:

So, the slope of AB is -10.

Remember that the slopes of perpendicular lines are negative reciprocals of each other.

Therefore, the slope of our Line D is the negative reciprocal of -10. Which is -10 flipped and multiplied by a negative.

So, Line D has a slope of 1/10.

Now, since Line D is also the perpendicular bisector of AB, we need to find the midpoint of AB since Line D must pass through this point.

To find the midpoint, we can use the midpoint formula:

We can again let (4, -3) be (x₁, y₁) and let (3, 7) be (x₂, y₂). Substitute them into the midpoint formula to obtain:

Evaluate. So, the midpoint is:

Now, we can find the equation of our Line D. We know that its slope is 1/10, and that it must pass through (3.5, 2). So, we can use the point-slope form:

Where m is the slope. Let's let (3.5, 2) be (x₁, y₁) and substitute 1/10 for m. This yields:

This is the same as choice C. So, choice C is indeed an equation of Line D.

We can distribute the right to obtain:

Add 2 to both sides to acquire:

This is the same as choice D. So, choice D is indeed an equation of Line D.

Moreover, we can put this into standard form by multiply everything by 10, which gives:

Subtracting x from both sides yields:

This is the same as A. So, choice A is also an equation of Line D.

There is no way to acquire choice B. So, B is not an equation of Line D.

Therefore, our answer is B.

And we're done!

I took it and got 5 out of 5 right ✅

Answer:

Step-by-step explanation:

If the value of x will be 11 degrees. Then the measure of angle ∠AEB will be 72 degrees.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Vertically opposite angle - When two lines intersect, then their opposite angles are equal.

Two lines AC and BD are intersecting each other at point E.

The angle ∠AEB = 7x - 5 and the angle ∠CED = 2(4x - 8).

Then the measure of angle ∠AEB will be

We know the angle ∠AEB and ∠CED are the vertically opposite angle. Then they both are equal.

∠AEB = ∠CED

7x - 5 = 2 (4x - 8)

7x - 5 = 8x - 16

16 - 5 = 8x - 7x

      x = 11

Then the measure of angle ∠AEB will be

∠AEB = 7x - 5

∠AEB = 7 (11) - 5

∠AEB = 77 - 5

∠AEB = 72°

Answer:

15cm

Step-by-step explanation:

150 meters are too long since 1 meter is about one big step.

15 meters would also be too long.

150 centimeters is the same as 1.5 meters, which is also too long.

volume is lwh

volume is 3*3*10

volume is cubic cm

volume is 90

volume is 90 cubic cm

Answer:

90cm^2

Step-by-step explanation:

3x3=9

9x10=90

Reason:

The tree is already 48 inches tall. We add on 3x to represent the idea the tree is growing 3 inches per month. Therefore, the total height is 48+3x or 3x+48 inches.

Let's say x = 5 months have elapsed as an example.

The tree would have grown 3*x = 3*5 = 15 inches to get 48+15 = 63 inches tall. In other words, y = 3x+48 will have y = 63 when x = 5.

Answer:

x < 0

( x is less than 0 )

Explaination:

That open circle point means the answer will not be equal to, which would be options including <(less than) or >(greater than).

If the circle was closed you would use these symbols, ≤(less than or equal to) and ≥(greater than or equal to)

The open circle lands on 0 and the arrow points to the left into the negative numbers. The answer should be x<0 or x is less than 0.

A way to help remember less than vs greater than on a line like this is that the arrow points in the same direction as the symbol! For example, your question shows an arrow going to the left, and the symbol used for it is less than (<) which also looks like a left pointing arrow.

The length of arc JL is 24.46 units see attachment for diagram.

An arc is a part of the circumference of a circle that meets two radii of a circle to form a sector.

Analysis:

From bigger triangle, if we bisect 144, the line meets JL at 90°.

To find AL,

sin 72 = AL/6

AL = 6 sin 72 = 5.71

To find the angle at O

∠O = 2∠K ( twice angle at circumference is equal to angle at center)

∠O = 2 (144) = 288°

For smaller right-angled triangle,

sin 144 = AL/OL

sin 144 = 5.71/OL

OL = radius of circle =  5.71/0.587 = 9.73 unit

length of arc JL = ∅/360 x 2πr

= 144/360 x 2 x 3.142 x 9.73 = 24.46 units

In conclusion, the length of arc JL is 24.46 units

Answer:

1) 45%

2) 24%

Step-by-step explanation:

1) Total number of people surveyed = 26 + 84 + 72 + 34 = 216

    number of people who own a smartphone = 26 + 72 = 98

           ∴ relative frequency = [tex]\frac{98}{216}[/tex]   ˣ   100 = 45%

2) Total number of elementary school students = 26 + 84 = 110
