Can someone explain to me how to combine like terms?(7th grade)
Like can you give me an example problem then tell how to solve it.
Answer:
When two numbers in an equation have the same variable and or charge, then you use the commutative property to put them next to each other.
Step-by-step explanation:
Example:
4x + 2 + 3x - 1 <--- Here is the original equation.
4x + 3x + 2 - 1 <---Use the commutative property to add the like terms
together. 3x and 4x end in the same variable. 2 and 1 both
have no variable. Therefore both of the groups are like
terms.
7x + 1 <--- Add/subtract the live terms together.
8x <--- Here is your answer.

Answer:
a. 4x³+13x²+9
Step-by-step explanation:
1. Distribute 4x to every term in the second set of parenthesis to get:
4x³-16x²+12x
2. Distribute 3 to every term in the second set of parenthesis to get:
3x²-12x+9
3. Add/subtract terms with the same variables/degrees:

Write 24 as a product of primes.
Use index notation when giving your answer.
Answer:
2^3 * 3
Step-by-step explanation:
Here are the first several prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23
To find the prime factorization of a number, start by dividing the number by the smallest prime number it is divisible by. Keep dividing by that prime number until you can't anymore. You only divide by prime numbers that divide evenly. Then move on to the next prime number that divides evenly, and do the same. You eventually will get to 1. Then you put together all the prime factors.
This is much easier to do than it sounds like in this explanation.
Start with 24.
24/2 = 12
12/2 = 6
6/2 = 3 3 is not divisible by 2, so we move on to 3.
3/3 = 1 We got to 1, so we are done.
The prime factorization is the product of all the prime numbers we divided by which are in bold.
24 = 2 * 2 * 2 * 3
Now we index it:
24 = 2^3 * 3

What is x?
Answer:
x = 4
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
7(2x - 5) = 21
Step 2: Solve for x
Distribute 7: 2x - 5 = 3Isolate x term: 2x = 8Isolate x: x = 4Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 7(2(4) - 5) = 21Multiply: 7(8 - 5) = 21Subtract: 7(3) = 21Multiply: 21 = 21Here we see that 21 does indeed equal 21.
∴ x = 4 is the solution to the equation.

If sea level = 0, write an integer that represents 25 feet below sea level.
Answer: -25
Step-by-step explanation:
The required integer that shows that 25 feet below the sea level is -25.
Given that,
To determine the in integer that represents 25 feet below sea level.
A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here,
The sea level is set to equal to 0,
Now height above the seal level comprises of positive sign, and the height below the sea level comprises of negative sign.
So, for 25 feet below sea level,
-25 is the required integer that represents the 25 feet below sea level.
Thus, the required integer that shows that 25 feet below sea level is -25.

22) The length of tangents drawn from
an external point to a circle are equal to
4 cm and radius is 3 cm then the
distance of external point from the
centre is
O 2 cm
O 3 cm
O 4 cm
O 5 cm
Answer:
The length from the external point to the center of the circle is 5 cm
Step-by-step explanation:
Here, we want to calculate the distance from the center of the circle to the external point
Please check attachment for diagram
Now, from what we know, the tangent and the radius meets at right angle
So we have a right-angled triangle with the length from the external point to the center of the circle as hypotenuse;
While the radius and the length of the tangent to the circle as the other sides
Using Pythagoras’ theorem, the square of the hypotenuse equals the sum of the squares of the two other sides
Let the length we want to calculate be x
x^2 = 3^2 + 4^2
x^2 = 9 + 16
x^2 = 25
x = √25
x = 5 cm

Eli’s runs 5/6 mile in 10 minutes
Based on the given parameters, Eli’s speed is 5/60 miles per minute
What is Speed?The speed of an object is the rate of change of the distance moved by the object with respect to time
How to determine Eli's speed?The given parameters are
Distance = 5/6 miles
Time = 10 minutes
The speed is calculated as
Speed = Distance/Time
So, we have
Speed = 5/6 miles/10 minutes
Evaluate
Speed = 5/60 miles per minute
Hence, Eli’s speed is 5/60 miles per minute

Answer: x= anything less than or equal to 5.
Step-by-step explanation: Because if you plug 5 in the answer for the equation on the right is 60. 60 is less than or equal to 60.
Answer: x ≤ 5
11x + 5 ≤ 60
⇔ 11x ≤ 60 - 5
⇔ 11x ≤ 55
⇔ x ≤ 55/11
⇔ x ≤ 5

Use the sketch tool to indicate what Edwin is describing as the parabola's "turning point."
Answer:
The sketch tool to indicate what Edwin is describing as the parabola's "turning point'' is described below in details.
Step-by-step explanation:
We can see in graph that it intersect X axis and it is open upward it means turning point is below X axis, we can find turning point by find maximum value of Y If open downward and minimum value, if open upward here we can find that minimum point is (3, -5). also you can draw axis of symmetry parabola and finds its intersection with turning point can also be named vertex of parabola.

Using the given exponential function, determine the growth/decay factor as well as the rate of increase/decrease. Type your answers in as numbers. Example: Growth Factor: 3.5, Rate of Increase: 2.5. (Do not input your rate of increase as a percent. If there are fractions, you can input your answer as a fraction. i.e. - 4/5, or 1/10)
f(x)=200(4/5)^x
Answer:
Growth rate is -1/5
Growth factor is 4/5
Step-by-step explanation:
Here, we want to get the growth rate and the growth factor
Generally for an exponential function given as;
y = a(1 + r)^n
r is the growth rate
1 + r is the growth factor
We can express the given exponential function as follows;
f(x) = 200(1-1/5)^x
So the growth rate is -1/5
The growth factor is 1-1/5 = 4/5

write an equation in slope intercept form for all these below
14.through: (5, 1) slope=3/5
15. through:(2, -4) slope=-1
17. through:(5,-2) and (-5,3)
Answer:
14. y= 3/5x-2
15. y= -1x-2
17. -1/2
Step-by-step explanation:
Since you have a point and a slope put it in point-slope form first.
Point-slope form: y-y1=m(x-x1)
Then solve for y.
Then you'll get the slope-intercept form.
For number 17 use the slope-intercept form y=mx+b
rise/run= m= y2-y1/x2-x1

Answer:
x = 3 is the solution
Step-by-step explanation:
3x + 4 = 5x - 2
when x = 3
so plug 3 into the equation where x is
so the equation becomes:
3(3) + 4 = 5(3) - 2
Then do the multiplication on both sides
9 + 4 = 15 - 2
Then do the addition and subtracition on both sides
13 = 13
Answer:
3x +4= 5x-2
3(3) +4 = 5(3) -2 (plug in the x values)
9+4= 15-2 (do the multiplication on both sides)
13= 13 (do the addition/ subtraction. pretty much all you're doing, is making sure that with the given x-value, the equation is true. and it is :))
