A line has a slope of 2. It passes through the points (1, 2) and (3, y) . What is the value of y? y=
malfutka [58]

Answer:

6

Step-by-step explanation:

To solve this , we use the equation of finding a slope wig a line.

m = (y2 - y1)/(x2 - x1)

From the question, we know that:

y2 = y

x2 = 3

y1 = 2

x1 = 1

m = 2

Hence,

2= (y - 2)/(3 - 1)

2 = (y - 2)/2

4 = y - 2

y = 2 + 4 = 6

Nikitich [7]

Answer:

Step-by-step explanation:

A. The first inequality is graphed as a shaded area below the solid line with x-and y-intercepts of 7.5 and 5, respectively. The second inequality is graphed as a shaded area above the solid line with x- and y-intercepts of 3.

The solution set is the set of integer-valued grid points one or between the lines.

__

B. The point (5, 1) is included in the solution area. Mathematically, it can be shown to satisfy the two inequalities:

  2(5) +3(1) ≤ 15   ⇒   13 ≤ 15   True

  (5) +(1) ≥ 3   ⇒   6 ≥ 3   True

__

C. The point (5, 1) is in the solution set. It means Michael can purchase 5 sandwiches and 1 hot lunch within his budget constraints. That will provide 6 meals, which is more than the minimum of 3 that he wants to provide.

How much simple interest is earned on $4,000 in 3 1/2 years at an interest rate of 5.2%?
AveGali [126]

Answer:

$728

Step-by-step explanation:

The formula for simple interest is I = PRT, where I = interest earned/paid, P = principal amount deposited or borrowed, R = rate of interest as a decimal, and T = time in years.

I = PRT

I = (4000)(0.052)(3.5)

I = 728
