1 answer:

Ivenika [448]3 years ago

7 0

Answer:

The slope is -2!

Step-by-step explanation:

Lets Solve!

3y +6x = 9

First we subtract 6x from both sides

3y = -6x + 9

Next we divide by 3 from both sides.

y = -2x + 3

The slope is -2!

Write an equation in slope-intercept form of the line with the given parametric equations.

Montano1993 [528]

Answer:

$y = \frac{9}{8}\cdot x -\frac{3}{8}$

Step-by-step explanation:

The parametric equations are described below:

$x = 8\cdot t + 3$ and $y = 9\cdot t + 3$

The slope-intercept equation is constructed by eliminating t from both formulae:

$t = \frac{x-3}{8}$ and $t = \frac{y-3}{9}$

$\frac{x-3}{8} = \frac{y-3}{9}$

$9\cdot (x-3) = 8\cdot (y-3)$

$9\cdot x - 27 = 8\cdot y -24$

$9\cdot x -3 = 8\cdot y$

$y = \frac{9}{8}\cdot x -\frac{3}{8}$

Tell if each equation represents exponential growth, exponential decay or neither.

scoray [572]

Answer:

Exponential growth A, B;

exponential decay C, E;

neither D.

Step-by-step explanation:

The function $y=a\cdot b^x$

represents exponential growth when $b>1;$
represents exponential decay when $0$

A. The equation $f(t)=\dfrac{2}{3}\cdot \left(\dfrac{7}{3}\right)^t$ represents exponential growth, because $\dfrac{7}{3}>1.$

B. The equation $P=22\cdot \left(1.76\right)^x$ represents exponential growth, because $1.76>1.$

C. The equation $V=\dfrac{1}{3}\cdot \left(0.45\right)^x$ represents exponential decay, because $0$

D. The equation $W=3.2\cdot (x)$ represents neither exponential growth nor exponential decay, because this function is linear.

E. The equation $g(x)=4.2\cdot \left(\dfrac{1}{3}\right)^x$ represents exponential decay, because $0$
