What is the equation of the line that is parallel to the line 5x + 2y = 12 and passes through the point (-2, 4)?
Korolek [52]

Answer:

y=-5/2x-1

Step-by-step explanation:

first find the gradient whereas since the two lines are parallel they hav the same gradient. y=mx+c whereas m is the gradient. 5x+2y=12

2y=-5x+12

y=-5/2x+12(so the gradient is -5/2x..... <u>g</u><u>r</u><u>a</u><u>d</u><u>i</u><u>e</u><u>n</u><u>t</u><u>=</u><u>-</u><u>5</u><u>/</u><u>2</u>

<u>y</u><u>-</u><u>4</u>=-5/2

x+2

y-4=-5/2(x+2)

y-4=-5/2x-5

y=-5/2x-5+4

y=-5/2x-1

On April 1, Preston McCord deposited $1,400 in a savings account that pays annual interest of 3.2%
lesya692 [45]

Answer:

After 6 months, the interest generated by the investment would be $21.10.

Step-by-step explanation:

To determine the interest that Preston McCord could earn by investing $ 1,400 in an account that pays 3.2% annual interest compounded monthly, leaving said money invested for a period of 6 months, it is necessary to perform the following calculation:

X = 1,400 x (1 + 0.032 / 6) ^ 0.5x6

X = 1,421.10

1421.10 - 1400 = 21.10

Thus, after 6 months, the interest generated by the account will be $ 21.10.

If f(3) = 3^x and g(x) = 7^x then the graph of g(x) will be — the graph of f(x) when x&lt;0.
Allushta [10]

Using the given exponential functions, it is found that the graph of g(x) will be less than than the graph of f(x) when x < 0.

<h3>What are the exponential functions?</h3>

The given exponential functions, f(x) and g(x), are respectively given by:

  • f(x) = 3^x
  • g(x) = 7^x

When x < 0, one possible value is x = -1, hence evaluating the functions at these values:

f(-1) = 3^{-1} = \frac{1}{3}

g(-1) = 7^{-1} = \frac{1}{7}

\frac{1}{3} > \frac{1}{7}, hence, the graph of g(x) will be less than than the graph of f(x) when x < 0.

What is the value of x in 0.8x = 7.2
Ann [662]

Answer:

x = 9

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

0.8x = 7.2

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Divide both sides by 0.8:                    x = 9

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

  1. Substitute:                    0.8(9) = 7.2
  2. Multiply:                        7.2 = 7.2

7.2 does indeed equal 7.2. ∴ x = 9 is a solution.

And we have our final answer!
