Answer:

x=56

Step-by-step explanation:

number = x

7/8x=8/7x-15

Add 15

15+7/8x=8/7x

Subtract 7/8

15=15/56x

x=56

The number is 56

Answer:

84°

Step-by-step explanation:

Let the measures of the triangle be 5x, 7x, 3x.

By interior angle sum postulate of a triangle.

5x + 7x + 3x = 180°

15x = 180°

x = 180°/15

x = 12°

7x = 7*12°= 84°

Measure of the largest angle = 84°

Answer:

m = undefined

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

If the slope m was equal to 0, then it would be a horizontal line rather than a vertical line.

Using the Vertical Line Test, we also know that the graph is not a function.

Usually a vertical line has an undefined slope, as x equals a certain number, and m = unknown.

Answer: It's undefined, because it's vertical

Answer:

Equation of line in slope-intercept form is: y = -8x-39

Step-by-step explanation:

Given points are:

(-4, -7) and (-6, 9)

The slope-intercept form is given by the equation

[tex]y = mx+b[/tex]

Here m is the slope of the line and b is the y-intercept.

m is found using the formula

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Here

(x1,y1) = (-4-7)

(x2,y2) = (-6,9)

Putting the values in the formula

[tex]m = \frac{9+7}{-6+4} = \frac{16}{-2} = -8[/tex]

Putting slope in general equation

[tex]y = -8x+b[/tex]

Putting (-6,9) in the equation

[tex]9 = -8(-6)+b\\9 = 48+b\\b = 9-48\\b = -39[/tex]

Putting the value of b we get

[tex]y = -8x-39[/tex]

Hence,

Equation of line in slope-intercept form is: y = -8x-39

Answer:

x = 2

Step-by-step explanation:

[tex]37x + 2 = 38x\\=> 38x-37x=2\\=> x = 2[/tex]

Answer:

x=2

Step-by-step explanation:

37x + 2 = 38x

<=> 2 = 38x - 37x

<=> 2 = x

So x = 2
