What is the constant in the expression 7x + 3
Answer:
3
Step-by-step explanation:
In expressions, there are 4 items to look at :
1. Terms
2. Coefficients
3. Like Terms
4. Constant Terms
Since 4. is the topic at hand, let's focus on that, constant terms are terms that cannot be changed value.
This would mean numbers without a variable, look at the expression below :
7x + 3
Since 3 doesn't have a variable, therefore 3 is a constant term.

FINDING SLOPE given GRAPHS, TABLES, POINTS and EQUATIONS!! Thank youu
The formula for slope is vertical change ÷ horizontal change, which means choose two points, (x1,y1) and (x2,y2), then do (y2-y1) ÷ (x2-x1).
For the graph, just pick two random points that you like. For the table, pick two sets of numbers (for example -10,-47 and 4,9). For the equation, create two sets of coordinates. For example, if you have f(x) = x + 3, then if x = 1, y = 4 and if x = 2, y = 5.

Answer:
(2, -1)Step-by-step explanation:
Given system:
-3x - 2y = -49x + 3y = 15Solving by elimination
Multiply the first equation by 3 and add up equations, then solve for y:
3(-3x) - 3(2y) + 9x + 3y = 3(-4) + 15-9x - 6y + 9x + 3y = -12 + 15-3y = 3y = 3/(-3)y = -1Find the value of x:
-3x - 2(-1) = -4-3x + 2 = -4-3x = - 4 - 2-3x = -6x = -6/(-3)x = 2The answer is: (2, -1)

The owner of a garden center pays $25 for each birdbath . She sells them for 15% more than she paid. Decide whether each expression represents the selling price for b birdbaths.
Answer:
The selling price is $28.75b.
Step-by-step explanation:
There are no options given but I will represent the word problem mathematically.
Let b stand for all the birdbath. If the owner pays $25 for each, then he pays $25b.
Selling them for 15% more means, 15% of the cost price was added to the original price. Finding 15% of cost price we have:
15% x $25b = 0.15 x $25b = $3.75b.
Therefore, the selling price is given as
$25b + $3.75b = $28.75b.

Step-by-step explanation:
Amos scored 100 points while playing 3 rounds of a game.
Points
Round 1 - 30
Round 2 - 25
Round 3 - ?
Total - 100
How many points did he score in round 3?
Complete the steps to solve the problem.
1. What do you need to solve for this problem? Choose a variable to represent this unknown value.
2. Using the variable you chose, write an equation to represent this situation. (Hint: You may want to put the number of points in each round on one side and the total number of points on the other.)
3. Solve this equation to find how many points Amos scored in round 3. Show your work.
1. We can subtract the scores of the first and second rounds from the total score to obtain the score in the third round.
2. An equation including a variable to solve would be x + 30 + 25 = 100.
3. By solving the equation we obtain Amos scored 45 points in the third game.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
From the given information the score for her third round would be,
= (100 - 30 - 25).
= 100 - 55.
= 45.
Another way to solve this problem is assuming Amos scored 'x' in the third game.
Therefore, (30 + 25 + x) = 100.
55 + x = 100.
x = 100 - 55.
x = 45.

Triangle ABC has angle measures as shown.
(a) What is the value of x? Show your work.
(b) What is the measure of angle C? Show your work.
Answer:
Step-by-step explanation:
Answer:
12°Step-by-step explanation:
Sum of interior angles of the triangle is 180°:
m∠A + m∠B + m∠C = 180°3x + 28° + 5x + 52° + 2x - 10° = 180°10x + 70° = 180°10x = 110°x = 11°Find the measure of angle C:
m∠C = 2x - 10° = 2(11°) - 10° = 22° - 10° = 12°Three different, positive integers have a

PLEASE HELP WILL GIVE BRAINLIEST ANSWER!!! Thanks
Answer:
please check explanations
Step-by-step explanation:
As we all know, i is same as root of -1
let us expand what we have;
(1 + i)^2
= 1(1 + i) + i(1 + i)
= 1 + i + i + i^2
as i is square root of -1, the square of the square root of -1 is -1
Thus, we have
1 + 2i - 1
= 2i

Answer:
f(q) = 4
Step-by-step explanation:
Simplify.
h ⋅ 10q = 40 ⋅ q
Divide each term by 10 q and simplify.
h = 4
To rewrite as a function of q , write the equation so that h is by itself on one side of the equal sign and an expression involving only q is on the other side.
f(q) = 4
