You calculate slope by the rise over run. These people are confusing you a bit - do problem 2 then 1

the vertical change is -1 horizontal change is 3 so by rise/run=-1/3

-1/3 is the slope

for the second problem this is confusing but just read and try to analyze

vertical change/horizontal change = 5-4/0-3= 1/-3(or -1/3)

The y intercept is the point where the line hits the y axis, so at point (0, 5)

The function is y=mx+b

m is the slope

b is the y intercept

so y=-1/3x+5

Solve for x
-6x + 14 <-28
OR 9x + 15 < -12

Answers

Answer:

9x + 15 < -12 =x<−3

Step-by-step explanation:

Step 1: Subtract 15 from both sides.

9x+15−15<−12−15

9x<−27

Step 2: Divide both sides by 9.

1: -126=14k
2: -7+m=8
3: -17=x -15
4: -5=a/18

Answers

1. -9
2. 15
3. -2
4. -90

Answer:

1. k = -9

2. m = 15

3. x = -2

4. a = -90

Step-by-step explanation:

When doing these problems set them up as if the equal sign is a dividing line between two sides.

1. -126=14k

Divide both sides by 14 to get rid of the coefficient.

This gives you your answer -9=k

2. -7+m=8

Add 7 to both sides to isolate the variable.

This gives you your answer m=15

3. -17=x-15

Add 15 to both sides to isolate the variable.

This gives you your answer x=-2

4. -5=a/18

Multiply both sides by 18 to get rid of the denominator.

This gives you your answer of a=-90

Hope this helped!

Triangle ABC above has side a = 1 and side c = 2. What constraints does the triangle inequality theorem put on side b?

Answers

Answer:

[tex]3 > b[/tex]

Step-by-step explanation:

Given

[tex]a = 1[/tex]

[tex]c = 2[/tex]

Required

Inequality to measure the length of b

The triangle inequality theorem states that:

[tex]a + b > c[/tex]

[tex]a + c > b[/tex]

[tex]b + c > a[/tex]

On side b, we make use of:

[tex]a + c > b[/tex]

Substitute values for a ad c

[tex]1 + 2 > b[/tex]

[tex]3 > b[/tex]

The inequality is: [tex]3 > b[/tex]

25y^2-60y+36

Answers

Answer:

(5y-6)^2

Step-by-step explanation:

Note that the polynomial 25y^ 2  −60y+36 is a perfect square trinomial, so we will use the following formula.

A ^2 −2AB+B^2 =(A−B) ^2

 

In this example we have A=5y and B=6 so,

25y^2 −60y+36=(5y−6)^2

What is the area of this figure?

Answers

Answer:

58.5

Step-by-step explanation:

Split the figure into three shapes; square, trinagle, and rectangle.

Square is 3 ⋅ 3 = 9

Triangle's sides are 3 and 11 so...

(3 ⋅ 11)/2 = 16.5

Rectangle is 3 ⋅ 11 = 33

Once you have the area of all the figures, you just add them together so...

9 +16.5 + 33 = 58.5

Answer:

area of the figure= 58.3ft²

Step-by-step explanation:

area of the figure= area of trapezoid+ area of a rectangle

area of the figure= [½(a+b)*height]+ (length*breadth)

area of the figure= [½(3+14)*3]+ (11*3)

area of the figure=25.3+ 33

area of the figure= 58.3ft²
