X=12, y=7.5

Here is an explanation if you want to know how to do it:

First, look at the diagram and think about what you know so far. Since the lines are parallel, 5x+4y and 12y must be equal. We also know that there is a right angle, so since both angles are equal, 12y=90 and 5x+4y=90.

Solve for y by dividing 90 by 12 to get 7.5, so y=7.5. Sub in this value to the equation on top and you should get 5x+4(7.5)=90 4(7.5)=30, so subtract that from 90 to get 60 and divide 60 by 5 to get 12, so x=12.

The amount of money, in dollars, in a savings account after x years is given by M(x) = 10,000(1.03)x. What does the value 1.03 r

mr Goodwill [35]

Answer:

Option B) There is a 3 percent increase in the savings account each year.

Step-by-step explanation:

we have

$M(x)=10,000(1.03^x)$

This is a exponential function of the form

$y=a(b^x)$

where

M(x) represent the amount of money in a saving account

x represent the number of years

a is the original deposit (y-intercept)

b is the base

r is the rate or percent increase

$b=(1+r)$

The percent increase per year is the base of the exponential function decreased by 1.

$r=b-1$

In this problem we have

$a=\$10,000$ ---> original deposit

$b=1.03\\r=1.03-1=0.03=3\%$

Therefore

The percent increase per year is 3%

Assume that P(E) = 0.471 and P(F) = 0.595. If E and F are independent, find P(E and F)

dsp73

The value of the probability P(E and F) is 0.2802

<h3>Independent probability</h3>

Events are known to be independent if the occurrence of one does not affect the other.

Given the following parameters

P (E) =0.471

P(F) = 0.595

If E and F are independent, then;

P(E and F) = P(E)P(F)

P(E and F) = 0.471 * 0.595
P(E and F) = 0.2802

Hence the value of the probability P(E and F) is 0.2802

Use the distributive property to remove the parentheses. -6(5y-2u-3)

olga55 [171]

<h2>Answer: -30y + 12u + 18 </h2>

<h3>Step-by-step explanation:</h3>

<em> by multiplying each term in the parentheses by the term outside</em>

-6(5y-2u-3) = (-6 × 5y) + (-6 × - 2u) + (-6 × -3)

= -30y + 12u + 18

A line that passes through the point (4, 2) and has the slope of -3/2

mash [69]

The answer is: y = -3/2 x + 8

Graph:

To find the answer we use the formula;

y-y1 = M1 (x - x1)

y-2 = -3/2 (x-4)

When fully solved: the answer is:
y = -3/2 x + 8
