- e
============================================
Explanation:
The general form of a slope intercept equation is y = mx+b
m = slope
b = y intercept
Something like y = (-7/6)x + 1 matches with y = mx+b such that m = -7/6 is the slope and b = 1 is the y intercept. So that's why problem 1 matches with choice b (in column B).
Similar situations apply for problems 2 and 3
-----------
For problem 4, we can see the slope is m = -1, but unfortunately m = -1 isn't listed in column B. However, m = -7/7 is listed. So this is why problem 4 matches with choice a. This leaves problem 5 to match with choice e.
note: 6/7 = 12/14 after multiplying top and bottom by 2.
Answer:
x = 7
y = -2
Step-by-step explanation:
4x + 3y = 22 ---------------------(I)
5x - 4y = 43 ---------------------(II)
Multiply(I) by 4 and equation (II) by 3. And then add the equations
(I) * 4 16x + 12y = 88
(II) *3 <u>15x - 12y = 129</u> {Add & thus y will be eliminated}
31x = 217
x = 217/31
x = 7
Plug in the value of x in equation (I)
4*7 + 3y = 22
28 + 3y = 22
3y = 22 - 28
3y = -6
y = -6/3
y = -2

<h3>
Answer is Choice B. 1:1</h3>
Explanation:
We have three numbers that aren't even, and they are {1,3,5}
There are three numbers that are even, and they are {2,4,6}
The odds in favor of not getting an even number is 3:3 = 1:1
To list the odds in favor, you write the number of ways to get what you want, followed by a colon, then the number of ways to get what you don't want. In this case, both counts are 3. The ratio 3:3 reduces to 1:1 after dividing both parts by 3.
34=97+29=195 and this is your answer
