Answer:

expressions which represent exponential decay:

A. 900(0.05)^t

B. 700(0.9)^x

Step-by-step explanation:

Exponential decay functions has the next form:

y = ab^x

where b < 1

A. 900(0.05)^t , a = 900, b = 0.05, the variable is t instead of x. 0.05 < 1, then it represents exponential decay

B. 700(0.9)^x , a = 700, b = 0.9 < 1, then it represents exponential decay

C. 53(1.75)^(0.3x) = 53(1.75)^(0.3)(1.75)^x, a = 53(1.75)^(0.3), b = 1.75 > 1, then it doesn't represent exponential decay

D. 90(1.2)^t, a = 90, b = 1.2 > 1, then it doesn't represent exponential decay. (the variable is t instead of x)

E. .300(2.4)^(1.2y) = 300(2.4)^(1.2)(2.4)^y, a = 300(2.4)^(1.2), b = 2.4 > 1, then it doesn't represent exponential decay. (the variable is y instead of x)

F. 2x² + 9 , this is a quadratic function, then it doesn't represent exponential decay.

G. 18 – 3y, this is a linear function, then it doesn't represent exponential decay.

Find equation of line parallel to 2x+5y=8 at point (-1,0)

WITCHER [35]

Lines are parallel if they have the same slope. In order to write a new equation parallel to the one we are given, we have to know the slope of the line we are given. Solve it for y:

$5y=-2x+8$ so

$y=-\frac{2}{5}x+\frac{8}{5}$ .

That means that the slope of the given line is -2/5. We will now use the point we were given and fill in the slope-intercept form of a line with the x coordinate of -1 and the y coordinate of 0:

$0=-\frac{2}{5}(-1)+b$ so

$0=\frac{2}{5}+b$ and

$b=-\frac{2}{5}$ .

Now that we have the slope and the y-intercept (the b value we just solved for), we can write the new equation:

$y=-\frac{2}{5}x-\frac{2}{5}$ .

There you go!
