1 answer:

6 0

The sum of all the odd numbers from 1 to 99 is easy to explain. Take the first and last numbers, 1 and 99. They add up to 100. Then take the next two numbers, 2 and 98. They also add up to 100. If you keep doing this, you will get 25 numbers that can be multiplied by 100. So the answer is 2,500.

The line which rises to the left has slope of -1/3 and y intercept of 2 so we have

y = -1/3x + 2

3y = -x + 6

x + 3y = 6

Shading is below and the line is solid so the inequality is

x + 3y ≤ 6

The other line has equation

y = 3x - 1

and inequality is

y ≥ 3x - 1

The answer is B

How do i solve by using substitution

elena55 [62]

Answer:

a = 0, b = 3

Step-by-step explanation:

3a + b = 3

b = - 3a +3

2a - 5b = - 15

2a - 5(-3a + 3) = - 15

2a + 15a - 15 = - 15

17a = 0

a = 0

b = -3a +3 = - 3 *0 +3 = 3
