Answer:

False

Step-by-step explanation:

4x-3(5x-1)\\=4x-15x+3\\=-11x+3\\\\-11x+3\neq 3+9x\\Hence, As\ LHS\ doesnt\ equal\ to\ RHS\ ,\\The\ Answer\ is\ False\ .

Answer:

False

Step-by-step explanation:

  1. 4x − 3(5x − 1) simplifies to 3 - 11x, which is not the same as 3 + 9x, so they are not equal.

I hope this helps!

navik [9.2K]

You would use the POINT SLOPE FORMULA and the Slope Formula

which is as follows ...

slope formula : \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

point slope formula:  y - y_{1} = m(x - x_{1} )

∠A and ∠B are vertical angles. If m ∠A=(2x+26)∘ and ∠B=(3x−29)∘, then find the measure of ∠A.
Leya [2.2K]

The measure of angle (m ∠A) is 136°

<h3>Vertical angles theorem</h3>

From the question, we are to find the measure of angle A

From the given information, we have that

∠A and ∠B are vertical angles

Thus

∠A = ∠B

and

Also, from the given information,

m ∠A=(2x+26)°

and

m ∠B= (3x−29)°

∴ (2x+26)° = (3x−29)°

Now, solve for x

2x + 26 = 3x - 29

26 + 29 = 3x - 2x

55 = x

∴ x = 55

But measure of angle A is given by

m ∠A=(2x+26)°

Put the value of x into the equation,

m ∠A=(2(55)+26)°

m ∠A=(110+26)°

m ∠A = 136°

Hence, the measure of angle (m ∠A) is 136°
