Answer:

16. y=-5x-20; 17. y=6x+18, or factored y=6(x+3)

Step-by-step explanation:

Your slope is -5

y=-5x+b, solve for b by pluging the point (-3,-5) in for x and y

-5=-5(-3)+b, solve for b

-20=b, now rewrite the equation

y=-5x-20

Your slope is 6

y=-5x+b, solve for b by pluging the point (-3,-0) in for x and y

0=6(-3)+b, solve for b

18=b, now rewrite the equation

y=6x+18, or factored y=6(x+3)

The probability that event M will not occur is 0.8 and the probability that event R will not occur is 0.6. If events M and R can

morpeh [17]

Answer:

C. 3/5

Step-by-step explanation:

Probability that M will occur =1-0.8=0.2=1/5

Probability that R will occur = 1-0.6=0.4=2/5

Probability that either of them will occur= 1/5 + 2/5= 3/5

The value of an autographed baseball from 2017 is $300. The value of the baseball exponentially increases by 5% each year after

lord [1]

For this case we have a function of the form:

$y = A * (b) ^ x$

Where,

A: initial value of an autographed baseball

b: growth rate

x: number of years

Substituting values we have:

$y = 300 * (1.05) ^ x$

For the moment when the value is at least 650 $ we have the following inequality:

$300 * (1.05) ^ x \geq 650$

Answer:

a one-variable inequality that could be used to solve for the number of years, x, it would take for the baseball to be worth at least $650 is:

$300 * (1.05) ^ x \geq 650$

Find an equation of variation in which y varies directly as x and y = 60 when x = 0.4. Then find the value of y when x = 2

Nostrana [21]

Answer:

y = 300

Step-by-step explanation:

The equation of variation in which y varies directly as x is written Mathematically as:

y ∝ x

y = k × x

y = kx

Where k = Proportionality Constant

We find k

a) y = 60 when x = 0.4.

60 = 0.4 × k

k = 60/0.4

k = 150

b) find the value of y when x = 2

y = kx

k = 150

Hence,

y = 150 × 2

y = 300
