Answer:

D. y = 2x + 3​

Step-by-step explanation:

Use the table to answer the question.

x:-2  -1   0   1    2

y: -1   1   3   5   7

Which equation represents the relationship between x and y shown in the table.

Solution:

The table shows a linear relationship between x and y.

A linear equation is in the form y = mx + b, where y is a dependent variable, x is an independent variable, m is the rate of change (slope) and b is the value of y when x = 0.

The table (x, y) has the points (-2, -1) and (0, 3). The equation is given by:

y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-(-1)= \frac{3-(-1)}{0-(-2)} (x-(-2))\\\\y+1=2(x+2)\\\\y+1=2x+4\\\\y=2x+3

butalik [34]

Answer:

9h +18x

Step-by-step explanation:

\frac{f(x +h) -f(x)}{x+h -x} \\ \frac{9(x +h)^2 +3 -(9x^2 +3)}{h} \\ \frac{9(x^2 +2xh +h^2) +3 -9x^2 -3 }{h} \\ \frac{9x^2 +18xh +9h^2 +3 -9x^2 -3}{h} \\ \frac{9h^2 +18xh}{h} \\ 9h +18x

Maxwell House Coffee contains 13% Columbian coffee beans by volume while
user100 [1]

<em>x</em> kg of Maxwell House coffee contains 0.13<em>x</em> kg of Columbian beans.

<em>y</em> kg of Folgers contains 0.21<em>y</em> kg of beans.

You want a mixture weighing 70 kg, so

<em>x</em> + <em>y</em> = 70

You also want this blend to consist of 19% Columbian beans, or 0.19 (70 kg) = 13.3 kg, so

0.13<em>x</em> + 0.21<em>y</em> = 13.3

Solve for <em>x</em> and <em>y</em> :

<em>x</em> + <em>y</em> = 70   ===>   <em>y</em> = 70 - <em>x</em>

0.13<em>x</em> + 0.21<em>y</em> = 13.3   ===>   0.13<em>x</em> + 0.21 (70 - <em>x</em>) = 13.3

0.13<em>x</em> + 14.7 - 0.21<em>x</em> = 13.3

14.7 - 13.3 = 0.21<em>x</em> - 0.13<em>x</em>

1.4 = 0.08<em>x</em>

<em>x</em> = 17.5

<em>y</em> = 52.5

Please help me !! Demonstrate the identity
Evgesh-ka [11]
Prove: \frac{1 - cos(2x) + sin(2x)}{1 + cos(2x) + sin(2x)} = tan(x)

LHS = \frac{1 - cos(2x) + sin(2x)}{1 + cos(2x) + sin(2x)}

cos(2x) = 1 - 2sin^{2}(x) = 2cos^{2}(x) - 1
sin(2x) = 2sinxcosx

LHS = \frac{1 - 1 + 2sin^{2}(x) + 2sinxcosx}{1 + 2cos^{2}(x) - 1 + 2sinxcosx}
= \frac{2sinx(sinx + cosx)}{2cosx(cosx + sinx)}
= \frac{2sinx}{2cosx}
= tanx = RHS

\therefore \frac{1 - cos(2x) + sin(2x)}{1 + cos(2x) + sin(2x)} = tan(x)

(6x -1)(x+2)

6x * x = 6x^2

6x * 2 = 12x - 1x = 11x

-1*2 = -2
