Mathematics

Answer:

B. y = x - 12

Step-by-step explanation:

First, find the <em>rate of change</em> [<em>slope</em>]:

\frac{-y_1 + y_2}{-x_1 + x_2} = m

\frac{5 - 9}{-7 + 3} = \frac{-4}{-4} = 1

Then use the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em> because you get it done faster that way. It does not matter which ordered pair you choose:

−9 = 3 + b

−12 = b

y = x - 12

________________________________________________________________________________________________

−5 = 7 + b

−12 = b

y = x - 12

** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.

I am joyous to assist you anytime.

Otrada [13]
Answer: C. Infinite
Explanation: (To explain this answer, I'll use 1 = 1) When you get 1 = 1 after doing an equation, this mean the answer is "all real numbers", which is the same term as "infinite" because it will always be true. Therefore, 0 = 0 will always be a true statement.

Maricopa's Success scholarship fund receives a gift of $ 75000. The money is invested in stocks,
Airida [17]

Answer:

Maricopa's Success invests $25,000 in stocks, $40,000 in bonds, and $10,000 in CDs.

Step-by-step explanation:

a = Stocks

b = Bonds

c = CDs

a + b + c = 75000

b = 30000 + c

a = 75000 - c - 30000 - c = 45000 - 2c

0.065(45000 - 2c) + 0.044(30000 + c) + 0.0225c = 3610

2925 - 0.13c + 1320 + 0.044c + 0.0225c = 3610

0.0635c = 635

c = 10000

So b = 40000 and a = 25000
