Answer:
(-3u^2 + 7u - 2) + (4u^2 + 6u + 1)
= -3u^2 + 7u - 2 + 4u^2 + 6u + 1
= 4u^2 - 3u^2 + 7u + 6u + 1 - 2
= u^2 + 13u - 1
Hello!
There are 12 inches in a foot.
Kelly buys two shelves that measure 7 feet altogether, and the cost of each foot is $1.25.
Multiply the number of feet by the cost per foot.
7 × 1.25 = 8.75
Add this to the cost of the rest of her items.
90 + 8.75 = 98.75
Finally, subtract this from the $100 Kelly will use to pay.
100 - 98.75 = 1.25
ANSWER: Kelly will receive $1.25 change after her payment.

Step-by-step explanation:i'll explain how to identify integers.
The integers are ..., -4, -3, -2, -1, 0, 1, 2, 3, 4, ... -- all the whole numbers and their opposites (the positive whole numbers, the negative whole numbers, and zero). Fractions and decimals are not integers. For example, -5 is an integer but not a whole number or a natural number. ... Integers are numbers that do not have a fractional part, including positive and negative numbers and zero. Whole numbers are positive integers and zero. Natural numbers are positive integers and are sometimes called counting numbers. tell me if you need me to explain more.
Answer:
Incomplete Question

Step-by-step explanation:
To answer this question, I'll give conditions which satisfy each of the above characteristics of a scatter plot
1. Negative Correlation:
This type of correlation is achieved when either or both values of X and y on the graph decrease
2. Positive Correlation
This is achieved when the slope (value) of both x and y increase
3. Strong Correlation
This is often achieved when there's uniformity in slope x and y.
4. Weak Correlation
This is achieved when there's no uniforms in slope x and y
5. Linear
Linearity refers to whether a data pattern is linear (straight)
6. Nonlinear
Non-Linearity refers to whether a data pattern is curved.
There is a theorem that says if parallel lines are cut by a transversal, then same-side interior angles are supplementary (add up to 180 degrees).
If lines p and r were parallel, then angles 28 and (3x + 2) would add up to 180 degrees.
(28) + (3x + 2) = 180
3x + 30 = 180
3x = 150
x = 50
