Okay, so the y-intercept is the "b" in this case and the m is your slope so, therefore, you have y=- 1/2x-5

Ipatiy [6.2K]

Answer:

41.1764...%

Step-by-step explanation:

60% on 50 questions is 30/50 correct since 30÷50=.6=60%

Between 30 and 50(inclusive) there are 21 numbers.(30,31,32...49,50).

There are 51 possibilities of scores,1-50/50 or 0/50

$600 is deposited in an account that pays 7% annual interest, compounded continuously. What is the balance after 5 years? Please

Anit [1.1K]

Answer:

$842

Step-by-step explanation:

The Total amount after a compound interest can be calculated using the formula:

$T = P(1 + \frac{R}{100})^{n}$

where P is the amount of deposit, R is the rate of interest, n is the duration.

Hence by substituting the values, we get:

$T = 600(1 + \frac{7}{100} )^5$

T = $842 (3 sf)

1. a square bulletin board has an area of 100ft^2 what is the side length of the bulletin board?

Answer: 10 ft

• Area = side × side

$100 = {s}^{2} \\ s = \sqrt{100} \\ side = 10 \: ft$

2.which is the correct classification of the vaule 2pi?

D. real,irrational

→ It is irrational because it has no denominator, it is real because it has no imaginary part, and it can be plotted on a number line.

3. simplify each expression

$\hookrightarrow \: - 9x + 12 - 10 + x \\ = ( - 9x + x) + 12 - 10 \\ = { \boxed{ - 8x + 2}} \\ \\ \\ \hookrightarrow \: \frac{3}{4} x + 17 - \frac{1}{4} x - 19 \\ \\ = \frac{3}{4} x - \frac{1}{4} x + 17 - 19 \\ \\ { \boxed{ = \frac{1}{2} x - 2}} \\ \\ \\ \hookrightarrow \: 13 + 12x - 4x - 14 \\ = 13 + 8x - 14 \\ { \boxed{ = 8x - 1}} \\ \\ \\ \hookrightarrow \: - \frac{3}{2} x - 68 + 2x + 8 \\ \\ = - \frac{3}{2} x + 2x - 68 + 8 \\ \\ { \boxed{ = \frac{1}{2}x - 60 }}$
