As equations get more complex it is important to use properties of equality to isolate the variable and solve the equation.
Here are the properties of equality you need to isolate terms and solve equations.
The Subtraction Property of Equality is used when you have an equation with addition in it. It states that you can subtract the same quantity from both sides of the equation without changing the equality.
The Addition Property of Equality is used when you have an equation with subtraction in it. It states that you can add the same quantity to both sides of the equation without changing the equality.
The Division Property of Equality is used when you have an equation with a variable multiplied by a number. It states that you can divide both sides of an equation by the same quantity (as long as that quantity is not equal to zero) without changing the equality.
The Multiplication Property of Equality is used when you have an equation with a variable divided by a number. It states that you can multiply both sides of an equation by the same quantity without changing the equality.
Let’s look at an example and use properties of equality to isolate the variable and solve the equation.

A high definition radio station charges $200 per year in addition to $50 per month for the first 3 months to receive its broadcast. Write a function using function notation to describe the situation.
Let's assume
number of months =x
A high definition radio station charges $200 per year
so, we get point as (0,200)
Assume
f(x) is the total amount of charges in a year
we can see that this is linear relationship
so, we can use formula
[tex]f(x)=mx+b[/tex]
in addition to $50 per month for the first 3 months to receive its broadcast
so, m=50
we can plug it
[tex]f(x)=50x+b[/tex]

What is 4,396.92 rounded to the. Nearest whole number
Answer:
4397
Step-by-step explanation:
Because 9 is closer to another 0, so you would round the 6 to a 7.
Evaluate the following expression when n = -7.
-9|n + 5|
Answer:
-18
Step-by-step explanation:
The tall sticks around n+5 are absolute value signs. Basically, all you need to do is work out what the answer to the problem is inside the signs, then make whatever the answer is positive, then multiply by -9.
-7 + 5 = -2 (that turns into 2)
-9 x 2 = -18
Sylvie finds the solution to the system of equations by graphing. y = 2/3 x + 1 and y = -2/3x – 1
Which graph shows the solution to Sylvie’s system of equations?
Remark
One of the ways you could solve this is to go to a place like Desmos and graph it for yourself. Then at least you would know what the answer looked like. Another way is to solve for the x value by equating the equations since the y has to be the same. We'll do both.
Solve For X
(2/3)x + 1 = -(2/3)x - 1 Add 1 to both sides
(2/3)x + 1 + 1 = - 2/3x Subtract (2/3x) from both sides.
2 = (-2/3)x - (2/3)x
Show the graph and comment
Notice that there is only one graph given that has a value of x = - 3/2 Normally you are not that lucky. Thanks for putting the graphs in. We are usually not that lucky and have to guess at the answer if it is a graph.
2 = - 4/3x Multiply both sides by 3
2 * 3 = - 4x
6 = - 4x Divide by - 4
6/-4 = x Reduce
-3/2 = x
Remark
The x value is wrong for the one on the left. It is also wrong for the third one from the left. And the last graph is also incorrect. Only the second from the left gives the right answer.
In two weeks, your class collected more than 380 cans of food for the annual food drive. In the first week, 145 cans were collected. How many cans c of food were collected in the second week? Write and solve an inequality.
145 + c = 380
145 - 145 + c = 380 - 145 -Subtract 145 from both sides of the equation
c = 235
So, they collected 235 cans in the second week.
Hope this helps!
To find out how many cans of food were collected in the second week, subtract the number of cans collected in the first week from the total number of cans collected in two weeks. The inequality representing the problem is c + 145 > 380. Solving the inequality, we find that more than 235 cans were collected in the second week.
Explanation:To find out how many cans of food were collected in the second week, we can subtract the number of cans collected in the first week from the total number of cans collected in two weeks. Let's assign a variable, c, to represent the number of cans collected in the second week. The inequality that represents the problem is: c + 145 > 380. To solve this inequality, we need to isolate the variable by subtracting 145 from both sides: c > 380 - 145. Simplifying further, we get c > 235. So, more than 235 cans of food were collected in the second week.

Where
[tex]a_n[/tex]: Last term
[tex]a_1[/tex]: First term
n: Number of terms
d: Difference
Rewriting according to the given common difference, we have:
[tex]a_n = a_1 + (n-1) (- 4.5)[/tex]
Answer:
[tex]a_n = a_1 + (n-1) (- 4.5)[/tex]
The explicit formula for an arithmetic sequence whose common difference is -4.5 is:
[tex]a_n=a_1-4.5(n-1)[/tex]

What is the area of polygon IJKL?
A.
120 square units
B.
125 square units
C.
130 square units
D.
140 square units
E.
150 square units
ANSWER
The correct answer is E
EXPLANATION
Polygon IJKL is a rectangle.
The area is given by;
[tex]Area=l\times w[/tex]
The coordinates of I are [tex](5,8)[/tex] and L[tex](-5,8)[/tex].
This is a horizontal line so it will be faster using the absolute value method rather than the distance formula
The length is
[tex]|IL|=|5--5|[/tex]
[tex]|IL|=|5+5|[/tex]
[tex]|IL|=|10|[/tex]
[tex]|IL|=10[/tex]
units
The coordinates of K are [tex](-5,-7)[/tex] and L[tex](-5,8)[/tex].
The width is
[tex]|LK|=|8--7|[/tex]
[tex]|LK|=|8+7|[/tex]
[tex]|LK|=|15|[/tex]
[tex]|LK|=15[/tex]
units
Therefore
[tex]Area=10\times 15[/tex]
[tex]Area=150[/tex] square units
The coordinates of K are [tex](-5,-7)[/tex] and L[tex](-5,8)[/tex].
Answer:
The correct answer option is E. 150 square units.
Step-by-step explanation:
A polygon is figure with at least 3 straight or definite sides or typically 5 or more straight sides.
Here the polygon we are given is a rectangle.
We know that,
Area of a rectangle = l x w
so we need to measure the length and width of the rectangle to find its area.
If we look closely, we can see the length of the rectangle above the x-axis is 8 units and the length below the x-axis 7 units which makes a total og 15 units.
While the width is 10 units (5 units on each side of the y-axis).
Area of the rectangle = 15 x 10 = 150 square units.
Therefore, the area of the polygon is 150 square units.

Susan uses 15 rolls of ribbon to decorate 10 wedding baskets. Each roll of ribbon is
[tex]5 \frac{3}{8} [/tex]
yards long. After she decorates the baskets, she decides to cut off another
[tex] \frac{3}{4} [/tex]
yard from the ribbons of each basket. Write and simplify an expression to find out how much ribbon was used on the baskets.
Answer:
Amount of ribbon used = [tex]73 \frac{1}{8} yards[/tex] = 73.125 yards.
Explanation:
Number of ribbon rolls = 15
Number of wedding basket = 10
Length of 1 ribbon roll = [tex]5\frac{3}{8}=\frac{5*8+3}{8} =\frac{43}{8}[/tex] yards.
Total length of 15 ribbon roll = [tex]15*\frac{43}{8} =\frac{645}{8}[/tex]yards.
Length of ribbon cutting from each basket = [tex]\frac{3}{4}[/tex]yards.
Total length of ribbon cutting from 10 baskets = [tex]10*\frac{3}{4}=\frac{15}{2}[/tex] yards
Amount of ribbon used
[tex]=\frac{645}{8}-\frac{15}{2}=\frac{645}{8}-\frac{15*4}{2*4}=\frac{645}{8}-\frac{60}{8}\\ \\ =\frac{585}{8} =73 \frac{1}{8} yards[/tex]
Amount of ribbon used = [tex]73 \frac{1}{8} yards[/tex] = 73.125 yards.
Kelly and Greta are asked to write an equation for the scenario below. “One person was able to plant 4 trees in the same amount of time that 5 people working together were able to plant 20 trees.” The girls agree that x represents the number of people working and y represents the number of trees planted. Kelly wrote the equation , and Greta wrote the equation . Which person is correct, and why? Kelly is correct; each person plants more trees than the person before them. Kelly is correct; and . Greta is correct; each person plants 4 more trees than the person before them. Greta is correct; and .
Answer: Greta is correct.
Explanation:
Greta is correct sine you can substitute different number of people for each of the values of and y and check that each person will still plant 4 trees.
For example:
4x = 4(1) = 4 trees; and
4 x 5 = 20
but you should follow a certain pattern to increase the value of x, such that every foe every value of x, one person is able to plant 4 trees.
Answer:
the answer is D
Step-by-step explanation:
mx=n-p solve this equation for x
x = [tex]\frac{n-p}{m}[/tex]
isolate x by dividing both sides by m
x = [tex]\frac{n-p}{m}[/tex]

Obviously, if he were to only maximize his income he would put all money on the higher interest. But to reduce the risk he will balance the investment. He will put a fraction a (between 0 and 1) of the 710000 on 1% and the rest (1-a) on the 4.5%. Both interests together must then satisfy to add up to 18000.
So written as an equation:
[tex]710000\cdot a\cdot 0.01 + 710000\cdot(1-a)\cdot 0.045 = 18000[/tex]
I am not going to solve step by step assuming you can solve for a (if not let me know) but the solution is
[tex]a = 279/497[/tex]
So that means he should put
[tex]710000\cdot \frac{279}{497} \approx 398571[/tex] on the 1% account, and the rest 311429 on the riskier 4.5% account.
