Using the slope formula, if y = -58, slope is 7, and the y-intercept is -15, solve for x.
HACTEHA [7]

Answer:

The value of x would be roughly -6.14

Step-by-step explanation:

To find x, all we need to do is put each of these values in for the variables that they represent. y obviously goes in for y. y-intercept is the b value, and slope is the m value.

y = mx + b

-58 = 7x - 15

-43 = 7x

-6.14 = x

If Valerie deposited 12,000 into an account threat earns 15% simple annual interest how much money will she have after 3 years
Ad libitum [116K]

Answer:

The amount which she will have into account after 3 years is  17,400  unit

Step-by-step explanation:

Given as :

The principal which is deposited into an account = 12,000  unit

The rate of interest simple annual = 15%

The Time period = 3 years

Let The amount which she have after 3 years = A  unit

<u>From simple Interest method</u>

Simple Interest = \frac{Principal\times Rate\times Time}{100}

Or , Simple Interest = \frac{12,000\times 15\times 3}{100}

Or,  Simple Interest = \frac{540,000}{100}

∴    Simple Interest = 5,400  unit

Now,

Amount = Principal + Simple Interest

Or, A =  12,000  unit + 5,400  unit

∴   A =  17,400  unit

Hence The amount which she will have into account after 3 years is  17,400  unit . Answer
