Answer:

(7/2, 27/2) or (3.5, 13.5)

Step-by-step explanation:

The x-coordinate of the midpoint is the average of the x-coordinates of the endpoints.

The y-coordinate of the midpoint is the average of the y-coordinates of the endpoints.

x-coordinate of the midpoint:

(-3 + 10)/2 = 7/2

y-coordinate of the midpoint:

(9 + 8)/2 = 27/2

Answer: (7/2, 27/2) or (3.5, 13.5)

Answer:

  x -2y = 14

Step-by-step explanation:

The x- and y-coefficients can be the same. The constant needs to change to make the given point satisfy the equation.

  x -2y = (2) -2(-6) . . . . . use (x, y) = (2, -6) to find the constant

  x -2y = 14

Answer:

Number 2: -3/10 (I think)

Number 4: 10a-5b-4

Number 6: x=5/2

Number 8: x=6

Step-by-step explanation:

Number 2:

3ysquared/2y-4x2

3(-1)squared/2(-1)-4x2

3x1/2(-1)-4x2

3x1/-10

-3/10

(I might be wrong with this one though)

Number 4:

10a-3b-4-2b

10a-5b-4

Number 6:

2(-3x+8)=4x-9

-6x+16=4x-9

-6x+16-16=4x-9-16

-6x=4x-25

-6x-4x=4x-25-4x

-10x=-25

-10x/-10=-25/-10

x=5/2

Number 8:

1(4x-8)/4=-x+10

4x-8/4=-x+10

4x-8/4+x=-x+10+x

8x-8/4=10

4x8x-8/4=4x10

8x-8=4x10

8x-8=40

8x-8+8=40+8

8x=48

8x/8=48/8

x=6

#a

m<5=40°

#b

m<2=140

#c

<5 and <2 are linear pair(looked properly in diagram) Hence they are supplementary.

#d

<5 and 2 are same side interior angles (Clearly shown on diagram .

#e

a||b

Let's verify

Let the angle below <1 be <3

Now

<2+<3=180

<5+<4=180

[tex]\\ \sf\longmapsto <5+<2=180[/tex]

Hence verified

Answer:

Below (correct me if i am wrong, mark me as brainliest if right)

Step-by-step explanation:

Let's narrow this down, shall we?

It could not be A, because AB and AD are not the same length, AD is a longer line

It is B, because AC an AD seem to be equal lengths

It is C because of B!  They are of equal length meaning ACD is a equilateral triangle

it could not be D because it appears to be a scalene triangle and have left as a longer side

It is E because CDE is a isosceles triangle

Answer Let me ask my brother

Step-by-step explanation:he would know

The required algebraic expression is c+4

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.

Given that a statement 4 plus c as an algebraic expression

We need to convert it into an expression,

4 = 4

plus = +

c = c

Therefore, arranging it = c+4

Hence, the required algebraic expression is c+4
