Answer:
wheres the expression
Step-by-step explanation:
Let x represent the smaller. Then x+1 is the greater of the two.
... x+1 = 2x +20
... 0 = x + 19 . . . . . subtract x+1
... x = -19
Your two integers are -19 and -18.
Answer:
A, B, and C
Step-by-step explanation:
Let's simply the equation first
- -2(-8 - 4y + 3/4)
- 16 + 8y - 1 1/2
What did Daniel do wrong?
Well, let's break down what I did and compare it to Daniel.
- <em>I multiplied -2 and -8x to get 16x. A negative number times a negative number is positive, and 2 times 8 is 16</em>
Daniel, on the other hand, added the two terms.
The first term should be positive (A)
- <em>I multiplied -2 and -4y to get 8y. The same sign rules apply.</em>
Daniel got a negative number, but it is supposed to be positive (B)
- <em>I multiplied -2 and 3/4 should be -6/4, which simplifies to -1 2/4 which is further reduced to -1 1/2</em>
Daniel multiplied and simplified incorrectly (C)

Total = 7 + 5 + 3 = 15
Green = 3
Red = 7
P(two green) = (3/15)(2/14) = 1/35
P(two red) = (7/15)(6/14) = 1/5
Answer: P(two green) = 1/35 ; P(two red) = 1/5
Part A
To graph this, we plot open holes at -2 and 3 on the number line. Shade between these open holes to represent values between -2 and 3, but we don't include the endpoints.
See figure 1 below.
===============================================
Part B
Solve the first inequality to get
Now solve the second inequality
We have
The graph will have an open hole at -3 and a closed/filled in circle at 1. We shade everywhere but the region between these marked values. The left portion in blue represents stuff smaller than -3; the right portion in red represents values equal to 1 or larger.
See figure 2 below.
