Answers

Answer 1

Answer:

To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. This is the value of m in the equation. Next, find the coordinates of the y-intercept--this should be of the form (0, b). The y- coordinate is the value of b in the equation.

1.Factor: 4x^2+28x-36

2.Factor: 125x^6-27y^15

3.Multiply: (4x-7)(5x-8)

Answers

Answer:

1.   4(x² + 7x - 9)2.  (5x² - 3y⁵) (25x⁴ + 15x²y⁵ + 9y¹⁰)3.  20x² - 67x + 56

Step-by-step explanation:

1.  factor 4x^2+28x-36

= 4x² + 28x - 36

re-write 36=4*9,  and 28=4*7

= 4x² + 4 * 7x - 4 * 9

factor out common term:

= 4(x² + 7x - 9)

2.  factor 125x^6-27y^15

= 125x⁶ - 27y¹⁵

=(5x²)³ - (3y⁵)₃

apply difference of cubes: x³-y³ = (x-y)(x²+xy+y²)

= (5x² - 36y⁵)(5²x⁴ + 5 * 3x²y⁵ + 3²y¹⁰)

refine:

= (5x² - 3y⁵) (25x⁴ + 15x²y⁵ + 9y¹⁰)

3. multiply (4x-7)(5x-8)

apply the FOIL method

= 4x * 5x + 4x (-8) + (-7) * 5x + (-7) (-8)

= 20x² - 67x + 56

How do i get A and B ?

Answers

Answer:

a=60°

b=300°

Step-by-step explanation:

the triangle is equilateral so all angles are 60 °

a = 60°

b=360 - 60 =300°

Answer:

A is 60°, B is 300°

Step-by-step explanation:

If you look closely, you can tell that this circle is divided into 6 triangles, but there is only one showing. This triangle is 1/6 of the circle.

You can find B by find 1/6 of 360° and subtracting that from 360, (a full circle is 360°)

1/6 of 360° is 60°

360° - 60° = 300°, so B is 300°

Now lets find A. Triangles are 180°. This triangle is obviously an equilateral triangle, so the measurements will all be the same.

180 ÷ 3 is 60, so A is 60°

I hope this helped, please mark Brainliest, thank you!

Solve for value of y.

Answers

Answer:

y = 6

General Formulas and Concepts:

A box at an angle signifies a 90° angle.

The 2 angles that add up to 90° are called Complementary Angles

Step-by-step explanation:

Step 1: Set up equation

The 2 angles are Complementary Angles. They must add up to 90°.

(6y + 5) + (8y + 1) = 90

Step 2: Solve for y

Combine like terms:                         14y + 6 = 90Subtract 6 on both sides:                 14y = 84Divide both sides by 14:                    y = 6

Answer:

y = 6

Step-by-step explanation:

So, the two angles sum up to 90 degrees.

Based on that, form an equation;

6y + 5 + 8y + 1 = 90

simplify,

6y + 5 + 8y + 1 = 90

14y + 6 = 90

inverse operations,

14y + 6 = 90

      -6     -6

14y = 84

/14     /14

y = 6

simplify 5(b – 4) + 12

John works at a factory and makes $11.25 an hour. This week he worked 45 hours
and last week he worked 39 hours. How much money did John make in the past 2
weeks?

Answers

Answer: $945

Step-by-step explanation: 11.25x39 is 438.75 and 11.25x45 is 506.25 and you add them together which is 945

So if he works for 45 hours and per hour he gets 11.25 then you would do 11.25x45=506.25 so then 11.25x39=438.75
So 506.25+438.75 so he made 945.00

Answers

Step-by-step explanation:

Hey there!

Given; The points are; (19,14) and (21,19).

Note: Use slope formula.

[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]

Put all values.

[tex]m = \frac{19 - 14}{21 - 19} [/tex]

Simplify it.

[tex]m = \frac{5}{2} [/tex]

Therefore, slope(m)= 5/2.

Hope it helps...

Answer:

slope = 5/2

Step-by-step explanation:

[tex]m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }[/tex]

[tex]\frac{19-(14)}{21-(19)}[/tex]

m=[tex]\frac{5}{2}[/tex]
