The answer is (-2,6)
Step-by-step explanation:
Answer: (-2, 6)
Step-by-step explanation:
An easy way to solve this is to plug in each answer into the system of inequalities to figure out with ordered pair adheres to the rules of both equation.
Let's use the first ordered pair as an example: (-3,4)
Is this true?:
4 > (-3)² +1
4 < (-3)² - (-3) + 1
No, it is not:
4 < 10
4 < 13

for which value of x is F(x)=0
A. 3
B. -5
C. -3
D. -6
Answers
Answer:
D) -6
Explanation:
f(x) = 0 suggests the x value which will make the function zero.
Find slope:
⇒ (y₂ - y₁)/(x₂-x₁)
⇒ (2 - 1)/(-2-(-4))
⇒ 1/2
Equation:
⇒ y - 2 = 1/2(x - (-2))
⇒ y = x/2 + 3
f(x) = x/2 + 3If f(x) = 0
x/2 + 3 = 0

The function is shown to be positive throughout the whole range [-3, -2] in graph (B).
According to the question,
Four alternative graphs representing various functions are supplied to us; our task is to identify the function graph that is positive over the whole range [-3, -2]. A closed interval exists. Therefore, it includes both -3 and -2.The graph of the Y value must be in a positive area during this interval. Therefore, we must choose a function that is positive over the whole range [-3, -2].Looking at the graph, we can see that the graph B has positive y-values in the range [-3, -2].
Hence The function is shown to be positive throughout the whole range [-3, -2] in graph (B).

Answers
Answer:
Step-by-step explanation:
Answer:
4xy(3a+2b+1)
Step-by-step explanation:
1) Find the Greatest Common Factor (GCF).
1 - What is the largest number that divides evenly into 12axy, 8bxy and 4xy?
It is 4.
2 - What is the highest degree of [tex]a[/tex] that divides evenly into 12axy, 8bxy and 4xy?
It is 1, since a is not in every term.
3 - What is the highest degree of [tex]x[/tex] that divides evenly into 12axy, 8bxy and 4xy?
It is x.
4 - What is the highest degree of [tex]y[/tex] that divides evenly into 12axy, 8bxy and 4xy?
It is y.
5 - What is the highest degree of [tex]b[/tex] that divides evenly into 12axy, 8bxy and 4xy?
It is 1, since [tex]b[/tex] is not in every term.
6 - Multiplying the results above,
GCF = 4xy
2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
[tex]4xy(\frac{12axy}{4xy} +\frac{8bxy}{4xy} +\frac{4xy}{4xy} )[/tex]

Carolyn bought two brands of socks. She bought a total of 5 pairs. One brand cost $2 each and the other brand cost $3 each. She spent $13. Find the number of pairs each brand of socks she bought
Answers
Answer:
Step-by-step explanation:
Declaration
Let Brand A number of 2.00 socks= x
Let Brand B number of 3.00 socks = y
Equations
Number of socks : x + y = 5
Cost of socks: 2x + 3y = 13
Solution
Multiply top equation by 2
2(x+ y = 5)
2x + 2y = 10
Write the new equation under the cost of socks equation
2x + 3y = 13
2x + 2y = 10 Subtract.
y = 3
She spent 3 dollars on 1 pair of socks.
Now she needs to calculate the number of 2.00 dollar socks
2x + 3y = 13
2x + 3*3 = 13 Combine the left
2x + 9 = 13 Subtract 9 from both sides.
2x +9-9 = 13-9 Combine
2x = 4 Divide by 2
2x/2 = 4/2
x = 2
Answer
#2 dollar socks = 2
#3 dollar socks = 3

( 0.004 ) ( 1 + 0.004 )
Answers
The TVM solver is a tool found in graphing calculators, that solve Time Value of Money problems.
The group of values that will return the same value as the given expression is;
D. N = 24; I% = 3.6; PV =; PMT = -415; FV = 0; P/Y = 12; C/Y = 12; PMT :END
What is Present Value?
Present value (PV) formula finds application in finance to calculate the present day value of an amount that is received at a future date.
In the TVM solver, we have;
I = The annual percentage rate
N = n × t
t = The number of years
PV = Present value
PMT = Payment
P/Y = Number of payments per year = n
C/Y = Number of compounding periods per year = n
The formula for monthly payment is presented as follows;
[tex]P = \frac{M[(1+r/n)^{nt} - 1]}{(r/n)(1+r/n)^{nt}}[/tex]
M = [tex]\frac{P.(r/n)(1+ r/n)^{nt} }{(1+ r/n)^{nt} - 1}[/tex]
Therefore, we get;
Where;
M = PMT = -415
P = PV
r = I
P/Y = n = 12
Therefore;
0.003 = I/12
I = 0.003 X 12 = 3.6%
N = n X t = 24
The value of the equation is the present value, PV = ?
When payment are made based on the PV, we have FV = 0
The group of values the same value as the expression
P = [tex]\frac{(415)[(1+0.003)^{24}-1]}{(0.003)(1+0.003)^{24}}[/tex]
when plugged into the TVM solver of a calculator is;
D. N = 24; I% = 3.6; PV =; PMT = -415; FV = 0; P/Y = 12; C/Y = 12; PMT :END

Select the correct answer. Simplify the polynomial expression. 3x(-2x+7) -5(x-1)(4x-3)
Answers
Answer:
The simplified form is -26x^2 + 56x -15
Step-by-step explanation:
We need to solve the expression:
3x(-2x+7)-5(x-1)(4x-3)
Multiplying the terms outside the bracket with the terms inside the bracket.
=-6x^2+21x-5(x(4x-3) -1(4x-3))
= -6x^2+21x-5(4x^2-3x-4x+3)
= -6x^2+21x-5(4x^2-7x+3)
Now multiply -5 with the terms inside the bracket
= -6x^2+21x -20x^2 +35x -15
Now, Combining the like terms:
= -6x^2 -20x^2 +21x+35x -15
Adding the like terms
= -26x^2 + 56x -15
So, the simplified form is -26x^2 + 56x -15
-26^2+56x-15 yea that should be the answer

h = 0
k = 0
b = 25
a = 60
Next, calculate c the distance from the center to the focus using:
[tex]c = \sqrt{a^2 -b^2}[/tex]
This gives
[tex]c = \sqrt{60^2 -25^2}[/tex]

Mean is a measure of central tendency that is used to determine the average of a set of numbers.
Mean = sum of the numbers / total number
Mean of set 1 = (29 + 31 + 27 + 33 + 30) / 5
