Answer:
Step-by-step explanation:(F)=1/F+6
We move all terms to the left:
(F)-(1/F+6)=0
Domain of the equation: F+6)!=0
F∈R
We get rid of parentheses
F-1/F-6=0
We multiply all the terms by the denominator
F*F-6*F-1=0
We add all the numbers together, and all the variables
-6F+F*F-1=0
Wy multiply elements
F^2-6F-1=0
a = 1; b = -6; c = -1;
Δ = b2-4ac
Δ = -62-4·1·(-1)
Δ = 40
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
F1=−b−Δ√2aF2=−b+Δ√2a
The end solution:
Δ‾‾√=40‾‾‾√=4∗10‾‾‾‾‾‾√=4√∗10‾‾‾√=210‾‾‾√
F1=−b−Δ√2a=−(−6)−210√2∗1=6−210√2
F2=−b+Δ√2a=−(−6)+210√2∗1=6+210√2

O $8.05
O $10.00
O $11.95
$19.50
Answer:
10 x 1.95 = 19.50 so D is your answer, $19.50
if Yasmin buys 10 pounds of peaches. Peaches cost $1.95 per pound then Yasmin pay $19.50 for the 10 pounds of peaches.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Yasmin buys 10 pounds of peaches
Peaches cost $1.95 per pound
we need to calculate the amount has to pay by Yasmin for the peaches.

Formula for slope is given as [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let,
[tex] (\frac{6}{2}, \frac{2}{3}) = (x_1, y_1) [/tex]
[tex] (2\frac{1}{2}, -\frac{2}{3}) = (x_2, y_2) [/tex]
[tex] m = \frac{-\frac{2}{3} - \frac{2}{3}}{\frac{3}{2} - \frac{6}{2}} [/tex]
[tex] m = \frac{\frac{-2 - 2}{3}}{\frac{3 - 6}{2}} [/tex]
[tex] m = \frac{\frac{-4}{3}}{\frac{-3}{2}} [/tex]

the sum of two numbers is 30 and their difference is 20. What are the two numbers?
[tex]\huge\pink{Answer}[/tex]
Let's start by calling the two numbers we are looking for x and y.
The sum of x and y is 30. In other words, x plus y equals 30 and can be written as equation A:
x + y = 30
The difference between x and y is 20. In other words, x minus y equals 20 and can be written as equation B:
x - y = 20
Now solve equation B for x to get the revised equation B:
x - y = 20
x = 20 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 30
20 + y + y = 30
20 + 2y = 30
2y = 10
y = 5
Now we know y is 5. Which means that we can substitute y for 5 in equation A and solve for x:
x + y = 30
x + 5 = 30
X = 25
Summary: The sum of two numbers is 30 and their difference is 20. What are the two numbers? Answer: 25 and 5 as proven here:
Sum: 25 + 5 = 30
Difference: 25 - 5 = 20

m∠AGF + m∠CGE + m∠AGC = 180° ( linear pair )
84° + 64° + m∠AGC = 180°
148° + m∠AGC = 180°
m∠AGC = 180 - 148
m∠AGC = 32°
As m∠AGC and m∠DGB are vertically opposite angles , their angle measure will be equal .
Which means :-
m∠AGC = m∠DGB ( vertically opposite angles )
m∠DGB = 32°Therefore :-try:- m∠DGB = 32° Reason :-vertical anglesIn the diagram shown, if m<AGF = 64°, m<CGE = 84°, then m<DGB = 32°
From the figure shown:
m<AGF = 64° (Given)
m<CGE = 84° (Given)
m<AGF = m<BGE (Vertically opposite angles are equal)
m<AGF = m<BGE = 64°
m<CGE + m<BGE + m<DGB = 180° (Sum of angles on a straight line)
84 + 64 + m<DGB = 180
148 + m<DGB = 180
m<DGB = 180 - 148
m<DGB = 32°
Therefore, in the diagram shown, if m<AGF = 64°, m<CGE = 84°, then m<DGB = 32°

Before 1918, approximately 40% of the wolves in a region were male, and 60% were female. However, cattle ranchers in this area have made a determined effort to exterminate wolves. From 1918 to the present, approximately 60% of wolves in the region are male, and 40% are female. Biologists suspect that male wolves are more likely than females to return to an area where the population has been greatly reduced. (Round your answers to three decimal places.) (a) Before 1918, in a random sample of 10 wolves spotted in the region, what is the probability that 7 or more were male
Answer:
P(≥ 7 males) = 0.0548
Step-by-step explanation:
This is a binomial probability distribution problem.
We are told that Before 1918;
P(male) = 40% = 0.4
P(female) = 60% = 0.6
n = 10
Thus;probability that 7 or more were male is;
P(≥ 7 males) = P(7) + P(8) + P(9) + P(10)
Now, binomial probability formula is;
P(x) = [n!/((n - x)! × x!)] × p^(x) × q^(n - x)
Now, p = 0.4 and q = 0.6.
Also, n = 10
Thus;
P(7) = [10!/((10 - 7)! × 7!)] × 0.4^(7) × 0.6^(10 - 7)
P(7) = 0.0425
P(8) = [10!/((10 - 8)! × 8!)] × 0.4^(8) × 0.6^(10 - 8)
P(8) = 0.0106
P(9) = [10!/((10 - 9)! × 9!)] × 0.4^(9) × 0.6^(10 - 9)
P(9) = 0.0016
P(10) = [10!/((10 - 10)! × 10!)] × 0.4^(10) × 0.6^(10 - 10)
P(10) = 0.0001
Thus;
P(≥ 7 males) = 0.0425 + 0.0106 + 0.0016 + 0.0001 = 0.0548
2. What is the x-intercept of the line
5x – 3y = 15? Write your answer as an ordered
pair.
Answer:
The x-intercept of the line is (3,0)
Step-by-step explanation:
5x - 3y = 15
5x - 3(0) = 15
5x - 0 = 15
(add 0 on both sides the cancel out -0)
5x = 15
(divide by 5)
x = 3
so the x-intercept is (3,0)
Write the function in vertex form. y=x^2+5x-9
Answer:
The function in the vertex form is y = (x + 2.5)² - 15.25
Step-by-step explanation:
The vertex form of the quadratic function y = ax² + bx + c is:
y = a(x - h)² + k, where
a is the coefficient of x²h, k are the coordinates of its vertex pointh = [tex]\frac{-b}{2a}[/tex]k equals y at x = h∵ The given function is y = x² + 5x - 9
∴ a = 1, b = 5, c = -9
→ Use a and b to find h
∵ h = [tex]\frac{-b}{2a}[/tex]
∴ h = [tex]\frac{-5}{2(1)}=-2.5[/tex]
∴ h = -2.5
→ Find y at x = -2.5
∵ y = (-2.5)² + 5(-2.5) - 9 = 6.25 - 12.5 - 9
∴ y = -15.25
∴ k = -15.25
→ Substitute a, h, k in the vertex form above
∴ y = 1(x - -2.5)² + -15.25
∴ y = (x + 2.5)² - 15.25
The function in the vertex form is y = (x + 2.5)² - 15.25
