2. How many solutions to the equation 2x +2 = 2(x+3)
O 1 solution
O Infinitely many solutions
O No solution

Answers

Answer 1

Answer:

O No solution

Step-by-step explanation:

2x +2 = 2(x+3)

Distributer the 2 on the right side.

2x + 2 = 2x + 6

Subtract 2x from both sides.

2 = 6

2 = 6 is a false statement.

Since we did two legal steps to solve the equation, and we ended up with a false statement, that means this equation has no solution.

Answer: O No solution

find the distance between the two given points. O(-3,-2) and P(-3,4)​

Answers

Answer:

[tex]\boxed {\boxed {\sf d= 6}}[/tex]

Step-by-step explanation:

Distance can be found using this formula:

[tex]d=\sqrt {(x_2-x_1)^2+(y_2-y_1)^2[/tex]

Where (x₁, y₁) and (x₂, y₂) are the points.

We are given the points O (-3, -2) and P(-3,4). Therefore,

[tex]x_1= -3 \\y_1= -2 \\x_2= -3 \\y_2=4[/tex]

Substitute the values into the formula.

[tex]d=\sqrt {(-3--3)^2+(4--2)^2[/tex]

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

Solve inside the parentheses first.

(-3--3)= -3+3=0(4--2)= 4+2=6

[tex]d= \sqrt {(0)^2+ (6)^2}[/tex]

Solve the exponents.

(0)²= 0*0=0 (6)²= 6*6=36

[tex]d=\sqrt {0+36[/tex]

Add.

[tex]d= \sqrt {36[/tex]

Take the square root.

[tex]d=6[/tex]

The distance is 6.

Answer:

A=35, B=55, and C=25

Step-by-step explanation:

Angle A and the angle next to it are linear pairs, so you can subtract 145 from 180.

if you already know Angle A, and that the other angle is 90 degress, you can add 90+35 and subtract it from 180 to get Angle B

Angle C is paired with the angle across from it (I forgot what the term is called) so it is 25 degrees.

A line is parallel to y = 4x + 1 and
intersects the point (-2,-5). What is the
equation of this parallel line?
y = [?]x + [

Answers

Answer:

y = 4x+3

Step-by-step explanation:

The equation in point slope form is expressed as y - y0 = m(x-x0)

m is the slope

(x0, y0) is the point on the line

If a line is parallel to y = 4x + 1, the slope of the line m = 4

Substitute m = 4 and the point (-2, -5) into the equation above;

y - (-5) = 4(x - (-2))

y+5 = 4(x+2)

y+5 = 4x+8

y = 4x+8-5

y = 4x + 3

Hence the equation of the line is y = 4x+3

The measure of the largest triangle is 72.

Step-by-step explanation:

Set up an equation to find the angle. note that angles in a triangle sum to 180.

With this information, we can set up an equation:

24x + 21x + 15x = 180

(add the x terms)

60x = 180

(divide both sides by 60)

x = 3

We now know what x equals. Now, we can multiply 3 by the largest angle of all- 24.

24 * 3 = 60.
