Answers

Answer:

expanded for everything

Step-by-step explanation:

Expanded Form of 531.029:

531.029 = (5 * 102) + (3 * 101) + (1 * 100) + (2 * 1/102) + (9 * 1/103)

531.029 = (5 * 100) + (3 * 10) + (1 * 1) + (2 * 1/100) + (9 * 1/1,000)

Jamal has a plan to save money for a trip. Today, Jamal deposits $8.00 into the savings account. Each week, Jamal will add $5.00 to the amount that is deposited into the savings account. The table below shows the relationship between the number of weeks and how much money, in dollars, Jamal deposits into the savings account. Week 0 1 2 3 4 Deposit (Dollars) 8 13 18 23 28 Let f(x) represent the amount of money Jamal deposits into saving account at the end of x weeks. Based on the table, what is f(8)?

Answers

Answer:

f(8) = $48

EQUATION

f(x)= 8+5(x)

Step-by-step explanation:

initial value = $8

every week there is an additional $5 added.

f(x) = 8+5x

f(8) = 8+ 5(8) = 8 + 40 = 48.

At the end of week 8 (x=8) , Jamal has $48 (y=48) saved.

Solve the following systems of linear equations below by elimination or by substitution method. y = 4/3 x - 9
y = x + 3

Answers

Answer:

x=33 and y=36

Step-by-step explanation:

You can rewrite the equation into

x+2=4/3x-9

Now you can subtract 2 on both sides

x=4/3x-11

Now subtract 4/3x on both sides:

-1/3x=-11

Multiply -3 on both sides:

x=33

Now substitute x with 33

y=33+3

y=36

Thus x=33 and y=36

Answers

Answer:

y = -10/3x -23

Step-by-step explanation:

Here's two options! You can either use slope-intercept formula or point-slope formula for the first steps.

We are trying to find m.

Slope-intercept formula:

m = y2-y1/x2-x1

Now let's identify our points, (-9,7) and (-6,-3).

= -3-7/-6+9

= -10/3

Point-slope formula:

y-y1 = m(x-x1)

Now let's identify our points, (-9,7) and (-6,-3).

-3 - 7 = m(-6 + 9)

-10 = 3m

-10/3 = m

Now, we have to use slope-intercept formula to find our b.

y = mx+b

y = -10/3x + b

Let's substitute one of the points, any given points work!

7 = -10/3(-9) + b

7 = 30 + b

-23 = b

Let's put it back in.

y = -10/3x -23

Seven less than one-fourth of a number is 2. What is the number?

Answers

Based on the equation given, it can be deduced that the value of the number will be 36.

Let the number be represented by x

Therefore, seven less than one-fourth of a number will be:

=(1/4 × x) - 7

= 0.25x - 7

Now, seven less than one-fourth of a number is 2 will be written as:

0.25x - 7 = 2

0.25x = 2 + 7

0.25x = 9

x = 9/0.25

x = 36

Write an equation for the line parallel to the line – 25x + 5y = -9 through the point (0,0).

help pls!

Answers

Answer:

Step-by-step explanation:

Rewrite the equation is standard format:  y = mx + b, where m is the slope and b is the y-intercept (the value of y when x=0).  \

– 25x + 5y = -9

5y = 25x - 9

y = 5x - (9/5)

This line has a slope of 5.  A parallel line will have the same slope as the reference line.  This means:

y = 5x + b

Any line with a slope of 5 will be parallel, regardless of the value of b.  We need b, however, since we also want this line to cross point (0,0).  We can use this point in the equation and solve for b:

y = 5x + b

0 = 0x + b

b = 0

Our line becomes y = 5x + 0, or

y = 5x  

[Note that we could also say b=0 just by looking at the given point.  The y-intercept, b, is the value of y when x=0.  The point we were given tells us y = 0 at x = 0.

Answers

Answer:

3.025

Step-by-step explanation:

the answer is 3.025 because 1/40 simplified is 0.025 and add the 3 to get 3.025

Answer: 3.0250

Step-by-step explanation: To convert this mixed number (fraction) to a decimal just follow these two steps:

Step 1: divide numerator (1) by the denominator (40): 1 ÷ 40 = 0.025

Step 2: add this value to the the integer part: 3 + 0.025 = 3.025. So,

3 1/40 = 3.025
