remember. y=mx+b

mx= slope

b= y intercept

the slope is positive and the slope is rise over run. the y intercept is when the line the y axis (doesn't matter if it is negative or positive). this makes it a positive two

Answer:

Both ate 52 degrees

Step-by-step explanation:

You can find the measure of angle 5 by subtracting 128 from 180, which equals 52. From there you can deduct that angles 3 and 1 are congruent to 5, making them both 52 degrees.

Answer:

2 to the power of six times 3 cubed times seven.

Step-by-step explanation:

The prime factors of 56 are 2 cubed times 7 and the prime factors of 18 are 2 times 3 squared The prime factors of 12 are 2 squared times 3.

A factor is a number that divides another number, leaving no remainder

The highest common factor of 18, 12, and 56 using prime factors is 2.

A factor is a number that divides another number, leaving no remainder

Example: 12 = 4 x 3 where 4 and 3 are the factors of 12.

We have,

18, 12, and 56

The factors of each number are:

18 = 2 x 9, 3 x 6, 18 x 1

So the factors of 18 are 2, 3, 6, 9, and 18.

12 = 2 x 6, 3 x 4, 12 x 1

So the factors of 12 are 2, 3, 4, 6, and 12.

56 = 2 x 28, 4 x 14, 7 x 8, 14 x 4

So the factors of 56 are 2, 4, 7, 8, 14, and 28.

Thus,

The highest common factor of 18, 12, and 56 using prime factors is 2.

Answer:

Step-by-step explanation:

15x+5y=8-3x

18x+5y=8⇒eqn 1

15x+5y=20y

15x-15y=0⇒eqn 2

eqn 1 * 3

 54x + 15y=24⇒eqn 3

eqn 3 + eqn 2

69x=24

x=24/69=0.3478

eqn  1⇒

    5y=8-18(24/69)

     y=1.7391/5

     y=0.3478

The solution to the system of equations is (10/3, -2).

Two or more expressions with an equal sign are defined as an equation.

The given equations are 15x + 5y = 20 and y = 8-3x.

15x + 15y = 20

Substitute y = 8-3x into the above equation:

15x + 15(8-3x) = 20

15x + 120 - 45x = 20

45x - 15x = 120 - 20

30x = 100

x = 10/3

Substitute x = 10/3 in y = 8 - 3x:

y = 8 - 3 (10/3)

y = 8 - 10

y = -2

Hence, the solution to the system of equations is (10/3, -2).

Perimeter of his fence = 120 m

Step-by-step explanation:

Given:

Area of square land = 3,600 m²

Find:

Perimeter of his fence

Computation:

Area of square land = 3,600 m²

4a² = 3,600 m²

a² = 900 m²

a = 30 m

Perimeter of his fence = 4a

Perimeter of his fence = 4 x 30

Perimeter of his fence = 120 m

Answer:

No, the student did not check the solution to the derived equation in the original equation.

No, a possible solution is a = –2, but it does not check in the original equation because it makes two of the denominators equal to zero.

No, a = –2 is an extraneous solution, and there is no solution to the original rational equation.

Step-by-step explanation:

just did on edge good luck!

The student is wrong in his answer to the equation

3/a + 2 − 6a/2a − 4 = 1/a − 2 is - 2, the correct answer is 2/3.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, 3/a + 2 − 6a/2a − 4 = 1/a − 2.

3/a + 2 - 3 - 4 = 1/a - 2.

3/a - 1/a = 3.

2/a = 3.

a/2 = 1/3.

a = 2/3.

Answer:

Step-by-step explanation:

Assuming that spoke refers to the radius (r) of the wheel, you can determine the circumference of the wheel using 2(pi)(r).

2 x (22/7) x 35cm

As this answer is in cm, it needs to be converted to m to be a correct answer. As 1m = 100cm, 220cm x 0.01 = 2.2m

Answer:

A"(-1, -3), B"(-2, -6), C"(1,-7)

Step-by-step explanation:

y= -4 is a horizontal line that cuts y-axis at (0, -4)

A'(-4, -5), B'(-5,-2), C'(-2,-1) are given on thhe graph

first we reflect over the line m, y= -4

A"(-4, -3), B"(-5, -6), C"(-2,-7) because the line m is the bisector of what conects the image and preimage points

second we translate T(3,0) so you add a 3 to the x coordinate of each point

A"(-4+3, -3), B"(-5+3, -6), C"(-2+3,-7)

A"(-1, -3), B"(-2, -6), C"(1,-7)

By definition of tangent,

tan(x) = sin(x) / cos(x)

so if tan(x) < 0, and we're given cos(x) = -1/4 < 0, then it follows that sin(x) > 0.

Recall the Pythagorean identity:

cos²(x) + sin²(x) = 1   →   sin(x) = + √(1 - cos²(x))

Then

sin(x) = √(1 - (-1/4)²) = √(15/16) = √(15)/4

Recall the double angle identity:

sin(2x) = 2 sin(x) cos(x)

Then

sin(2x) = 2 • √(15)/4 • (-1/4) = -2√(15)/16 = -√(15)/8
