If point D' is the image of D(-2,1) under a reflection across the x-axis. What are the coordinates of D'?
Answer:
(-2, -1)

When reflecting across the x-axis, the x coordinate remains the same, but the y-coordinate turns to its opposite. So to get D from D', keep -2, and make 1 a -1.
A movie theater sells 3 different sizes of popcorn: small, medium, and large. An order of popcorn comes with 4 different topping choices: butter, cheese, caramel, or salt.
How many unique ways can you order a bag of popcorn? (You can only select one topping.)
What is the probability that a randomly selected popcorn is large with either butter or salt?
Answer: 12
Step-by-step explanation:
The sizes are 3
toppings are 4
Using the Fundamental Counting Principal you multiply the selections:
( 3 x 4=12)
The number of unique ways that you can order a bag of popcorn if you can only select one topping is; 12 ways
How to solve probability combinations?
We are given the 3 different sizes of pop corn as;
SmallMediumLargeNow, we are told that an order of popcorn comes with 4 different topping choices. Thus;
Number of unique ways that you can order a bag of popcorn is;
N = 3 * 4 = 12 unique ways

What is the value of x
1.4x + 2.6x = -16
Answer:
x=-4
Step-by-step explanation:
1.4x +2.6x = -16
combine like terms (numbers with numbers, and numbers with variables together)
4x = -16
get x by itself (isolation)
x = -4
Answer:
[tex]x=-4[/tex]
Step-by-step explanation:
Start with:

EQUATIONS ON BOTH SIDES solve for -3 + 4x =37
Answer: x = 10
Step-by-step explanation:
-3 + 4x =37 .Add 3 to both sides
+3 -3 +4x = 37 +3 .
The +3 and -3 'cancel' to 0; 37 +3 = 40
4x = 40 . Divide both sides by 4 .
4x/4 is x, 40/4 is 10
x = 10

Summarize the rules for multiplying powers with the same base, dividing powers with the same base, and raising a power to a power. (in simple terms please)
Answer: multiplying powers with the same base-The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. In this example, you can see how it works. Adding the exponents is just a short cut! The "power rule" tells us that to raise a power to a power, just multiply the exponents.
dividing powers with the same base-To divide exponents (or powers) with the same base, subtract the exponents. Division is the opposite of multiplication, so it makes sense that because you add exponents when multiplying numbers with the same base, you subtract the exponents when dividing numbers with the same base.
raising a power to a power-Power Rule (Powers to Powers): (am)n = amn, this says that to raise a power to a power you need to multiply the exponents. There are several other rules that go along with the power rule, such as the product-to-powers rule and the quotient-to-powers rule.

Two angles in a triangle are 40 and 95. List the 3rd interior and two exterior angles.
Answer:
interior angle=45
two exterior angle= 140, 85
Step-by-step explanation:
sum of all angles= 180
40+95+x=180
x=180-135
x=45, ie the third interior angle=45
two exterior angles be y, z respectively
y=180-40(linear pair)=140
z=180-95(linear pair)=85

John made $200 this month mowing lawns.
Ashley had a yard sale and made 74% of what John
made. Chris received birthday money in an amount that
was of what Ashley made. How much birthday money
did Chris receive?
Answer:
B: $74
Step-by-step explanation:
To find out how much Ashley made, you need to find how much 74% is of 200. The answer to this is 148. Since Chris made 1/2 of what Ashley did, we have to divide 148 by 2. And you get 74
