By selling a television set for $421 Suzie incurred a loss of 6% . what is the cost price ?
Answer:
The cost price is $395.74 or $446.26
Step-by-step explanation:
When we do 421 times 0.06 (same thing as 6%) we get 25.26
We subtract 25.26 from 421 we get $395.74
If we add 25.26 to 421 we get $446.26

Someone please help me! Which one is independent and dependent
Answer:
The top is independent
The bottom is dependent
Step-by-step explanation:
The top is independent because it does not rely on another variable. It is the "affector" and not dependent on it.
The bottom is dependent because it does rely on another variable. It is dependent on this other variable because it will be affected by any changes in that other variable.

Hence, the number is -125.
Using algebraic expression, the number is calculated as: -125.
What is an Algebraic Expression?An algebraic expression involves using numbers and variables to make statements.
Let the unknown number be represented as x. Therefore:
Twice the number is 2x
2x is 500 more than 6x is 2x = 6x + 500
Solve the algebraic equation to find the number (x):
2x = 6x + 500
2x - 6x = 500
-4x = 500
x = -500/4
x = -125
Thus, using algebraic expression, the number is calculated as: -125.

What is the value of the coefficient of the 5th term in the expansion of (a + b) ^6
a. 20
b. 6
c. 10
d. 15
Answer:
D. 15
Step-by-step explanation:
I assume you know what pascal's triangle is if this is the work you must complete. If not, I have attached it below.
Now, raising (a+b) to the 6th term would expand to this, based on Pascal's triangle
[tex]\left(a+b\right)^6 = \quad a^6+6a^5b+15a^4b^2+20a^3b^3+15a^2b^4+6ab^5+b^6[/tex]
Remember that terms are separated by addition or subtraction symbols.
The 5th term of this 7 term expansion would be 15a^2b^4. The coeffecient is 15 in this case.

polynomials are named by the highest exponent of the variable as well as the number of terms. For example, x^5-3x^2-1 is a quintic trinomial. Quintic is the exponent of 5, which is the highest while trinomial implies three terms. Using the above example, name the following polynomial expressions: 4x^2+x-3

Answer:
The parabola is a horizontal parabola and it faces to the right. The vertex is at (3, -3) (*Double check this because I don't have graph paper*) because the vertex is always the same distance from the directrix and the focus.

y = 2x – 6
y = –4x + 3
Answer:
x = 3/2 | y = -3
Step-by-step explanation:
Given equations:
y = 2x - 6. . . .(i)y = -4x + 3. . . . (ii)Substituting from equation (i) for y:
==> 2x - 6 = -4x + 3
==> 2x + 4x = 6 + 3
==> 6x = 9
dividing both sides by 3:
==> 2x = 3
==> x = 3/2
Substituting 3/2 for x in equation (i):
==> y = 2(3/2) - 6
==> y = 3 - 6
==> y = -3
[tex] - 4x + 3 = 2x - 6 \\ 6x = - 9 \\ 2x = - 3 \\ x = - 1.5[/tex]

This is the graph of the function f(x) = k(3). The value k is a constant. Based on the graph, what is the value of k
By using the graph, we will see that k = 1.85
How to find the value of K?
Here we have the exponential function:
f(x) = k*(3)^x
And we want to find the value of k.
To find it, we need to use one point on the graph. the only one easy to read is the one for x = 3, we can see that when x = 3, f(x) = 50.
Then we have:
f(3) = 50 = k*(3)^3 = k*(3*3*3) = 27*k
Solving that for k we get:
50 = 27*k
50/27 = k = 1.85

4x + 2y = -1
5x – 3y = 7
Answer:
4x-2y=-1 multiply by 3
5x-3y=7 multiply by 3
12x+6y=-3
10x-6y=14 add them
so =22x=11
x=1/2
5(1/2)-3y=7
2.5-3y=7 take 2.5 to the other side
-3y=4.5
y=-3/2
therefore x=1/2 and y=-3/2

Write three rational numbers between −1 /5 and 1 /2
Answer:
-1/10, 2/10, and 4/10
Step-by-step explanation:
A rational number is a number that is in the form of p/q, where p and q are integers, and q is not equal to 0.
First, what is the lcm of 5 and 2? the lcm is 10, because that is the lowest number than can be divided separately by 5 and 2 and the results would still be a whole number.
We now need to find 3 rational numbers between -2/10 and 5/10. It's easy now that I've explained it, right?
-1/10, 2/10, and 4/10 are between -1/5 and 1/2 and are integers with the given explanation.

During the month of February, Lerato sends one SMS per day to relatives. Calculate how much this activity costs her in rands
Considering a linear function, it is found that this activity costs 240 rands.
What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, we suppose that:
There is a fixed cost of 100 rands, hence b = 100.Each SMS costs 5 rands, hence m = 5.Hence, the cost of sending x messages is given by:
y = 5x + 100.
February has 28 days, hence:
y = 5(28) + 100 = 240
This activity costs 240 rands.
