Answer:

B *second one down.

Step-by-step explanation:

EF = 1/2(AB + CD)

x+5 = 1/2 (2x + 2 + 2x+4)   Combine the like terms on the right.

x+5 = 1/2 (4x + 6)                Remove the brackets.

x+5 = 1/2*4x + 1/2*6

x+5 = 2x + 3                       Subtract x from both sides

5 = 2x-x + 3

5 = x + 3                            Subtract 3 from both sides

5-3 = x

x = 2

EF = x + 5

EF = 2 + 5

EF = 7

The answer is B

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:

Your answer is A, or -200.

Since your slope is going down, you know that the number is going to be a negative value. Then, check where the line hits a direct point. You would notice that it hits every 200 number values, which means that your answer is A.

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)

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]
