(4x-1) /2=x+7
4x-1 all over 2 = x +7​

Answers

Answer 1

Answer:

x = [tex]\frac{15}{2}[/tex]

Step-by-step explanation:

Given

[tex]\frac{4x-1}{2}[/tex] = x + 7 ( multiply both sides by 2 to clear the fraction )

4x - 1 = 2(x + 7) ← distribute

4x - 1 = 2x + 14 ( subtract 2x from both sides )

2x - 1 = 14 ( add 1 to both sides )

2x = 15 ( divide both sides by 2 )

x = [tex]\frac{15}{2}[/tex]

Which linear equation matches this graphed line?
y = 2x + 5
y = 1/2x-5
y = 2x+5
y = 1/2x + 5

Answers

The equation is y=2x+5 and there are two options like that so yea

Answer:

I think one of the choices was entered incorrectly. You have y=2x+5 listed twice. I believe the answer is y=-2x+5

Step-by-step explanation:

5 is the y-intercept and it is a +5 because it is above the x-axis. Slope = rise/run. In this case the slope should be negative thus -2x. Hope this helps.

1.) What is the relationship between angles 1, 2, and 3?b

Answers

Answer:

Exterior Angle Property of a Triangle

Step-by-step explanation:

According to exterior angle property of a triangle , the measure of any one exterior angle of a triangle is equal to the the sum of measure of it's opposite interior angles.

The relationship between angles 1, 2 and 3 is that they follows exterior angle principle. Therefore, ∠3 = ∠2 + ∠1

Exterior angle theorem

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.

In other word, the measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles

Therefore, the angle 3 is related to angle 1 and 2(remote interior angles) by the exterior angles theorem. Mathematically, this can be represented as follows:

∠3 = ∠2 + ∠1

Look at the rectangle and the square
Ada says that the length of diagonal SQ is two times the length of diagonal OM.
Is Ada correct? Justify your answer and show all your work. Your work should state the theorem you used to find the lengths of the diagonals

Answers

Answer:

NO. Ada is not correct.

Step-by-step explanation:

Using Pythagorean Theorem, find the length of the diagonal of the rectangle and the square, respectively.

✔️Diagonal of the Rectangle:

[tex] a^2 + b^2 = c^2 [/tex]

Where,

a = 8 in.

b = 16 in.

c = hypotenuse (longest side of a right ∆)

Plug in the values into the equation

[tex] 8^2 + 16^2 = c^2 [/tex]

[tex] 64 + 256 = c^2 [/tex]

[tex] 320 = c^2 [/tex]

Take the square root of both sides

[tex] \sqrt{320} = \sqrt{c^2} [/tex]

[tex] 17.9 = c^2 [/tex] (nearest tenth)

Length of diagonal SQ = 17.9 in

✔️Diagonal of the Rectangle:

[tex] a^2 + b^2 = c^2 [/tex]

Where,

a = 8 in.

b = 8 in.

c = hypotenuse (longest side of a right ∆)

Plug in the values into the equation

[tex] 8^2 + 8^2 = c^2 [/tex]

[tex] 64 + 64 = c^2 [/tex]

[tex] 128 = c^2 [/tex]

Take the square root of both sides

[tex] \sqrt{128} = \sqrt{c^2} [/tex]

[tex] 11.3 = c^2 [/tex] (nearest tenth)

Length of diagonal OM = 11.3 in.

SQ is not two times the length of OM.

Therefore, Ada is not correct.

Answer:

No Ada is not correct

Step-by-Step Explanation:

The length of diagonal SQ is not two times the length of diagonal OM. When you split the rectangle using the diagonal you can make a right triangle and use the Pythagorean Theorem to the rest of it. 

This would be the Rectangle:

a^2+b^2=c^2

8^2+16^2=c^2

64+256+c^2

320=c^2

√320

17.8

This would be the Square: 

a^2+b^2=c^2

8^2+8^2=c^2

64+64=c^2

128=c^2

√128

11.3

Now when I divide these answers that I came up with I get 1.7 which is not equal to 2 therefore SQ is not two times bigger than OM. 

I hope this helped :3
