Answer:

Look below

Step-by-step explanation:

So you know a point and the slope, now you can substitute the values of the point for the equation.

Answer: y = (5/2)x + 7

Step-by-step explanation:

Plug in given numbers into the following equation:

y = mx + b

Solve for b:

-3 = (5/2)(-2) + b

-3 = -10 + b

b = 7

Answer:

what? do you want them to be added?

Answer:

1. 14 = 2 + 12

2. 16 = 4 + 12

3. 18 = 6 + 12

4. 20 = 8 + 12

Step-by-step explanation:

Super easy. All you do is replace the numbers in your table with the corresponding letter. In this case we have a table of s and f.

Example for row two: f = s + 12. Replace s with 4 ( 4 is from your s column so you would replace it with that) then solve and plug in your answer (When you solve your answer, it will go under f column).16 = 4 + 12 . f = 16, s = 4.

Formula = f = s + 12.

1. 14 = 2 + 12

2. 16 = 4 + 12

3. 18 = 6 + 12

4. 20 = 8 + 12

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]

Answer:

3x³ + 12x² - 7x - 28

Step-by-step explanation:

(f • g)(x) = f(x) × g(x)

= (x + 4)(3x² - 7)

Each term in the second factor is multiplied by each term in the first factor, that is

x(3x² - 7) + 4(3x² - 7 ) ← distribute both parenthesis

= 3x³ - 7x + 12x² - 28

= 3x³ + 12x² - 7x - 28

Answer:

y=x+3

Step-by-step explanation:

The slope is 1 and the y-intercept is (0,3).

Answer:

84

Step-by-step explanation:

180-51-45=84

I think this would be the answer since triangles add up to be 84 and we are just finding the last missing angle.

hope this helps :)

Answer:

the answer is c - 84

Step-by-step explanation:

every triangle adds up to 180, so if you subtract 51 and 45 from 180, you will get 84

i hope this helps, have a great day :)

Answer:

[tex]f(x) = \frac{24}{25} * \frac{5}{6}^x[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (2,\frac{2}{3})[/tex]

[tex](x_2,y_2) = (3,\frac{5}{9})[/tex]

Required

Write the equation of the function [tex]f(x) = ab^x[/tex]

Express the function as:

[tex]y = ab^x[/tex]

In: [tex](x_1,y_1) = (2,\frac{2}{3})[/tex]

[tex]y = ab^x[/tex]

[tex]\frac{2}{3} = a * b^2[/tex] --- (1)

In [tex](x_2,y_2) = (3,\frac{5}{9})[/tex]

[tex]y = ab^x[/tex]

[tex]\frac{5}{9} = a * b^3[/tex] --- (2)

Divide (2) by (1)

[tex]\frac{5}{9}/\frac{2}{3} = \frac{a*b^3}{a*b^2}[/tex]

[tex]\frac{5}{9}/\frac{2}{3} = b[/tex]

[tex]\frac{5}{9}*\frac{3}{2} = b[/tex]

[tex]\frac{5}{3}*\frac{1}{2} = b[/tex]

[tex]\frac{5}{6} = b[/tex]

[tex]b = \frac{5}{6}[/tex]

Substitute 5/6 for b in (1)

[tex]\frac{2}{3} = a * b^2[/tex]

[tex]\frac{2}{3} = a * \frac{5}{6}^2[/tex]

[tex]\frac{2}{3} = a * \frac{25}{36}[/tex]

[tex]a = \frac{2}{3} * \frac{36}{25}[/tex]

[tex]a = \frac{2}{1} * \frac{12}{25}[/tex]

[tex]a = \frac{24}{25}[/tex]

The function: [tex]f(x) = ab^x[/tex]

[tex]f(x) = \frac{24}{25} * \frac{5}{6}^x[/tex]

Answer:

they both use y^2-y^1 and x^2 - x^1, one is to find the slope the other is to find the y intercept

Step-by-step explanation:

Slope-intercept is when you have a graph and a equation such as y=mx+b

y = y coordinate

m = slope

x = x coordinate

b = y intercept

point-Slope is when you have this equation and you use (x1, y1) as the coordinates to graph.

y - y1 = m * (x - x1)
