Answer:
-1114
Step-by-step explanation:
the lines are absolute value of the number on the inside
so the first 2 lines would equal 1114
but since there are 2 more lines its the opposite of 1114 which is -1114.

Solve: (a-7)(a+1) = 0
Answer:
0
Step-by-step explanation:
Answer:
a = −1 or a = 7
Step-by-step explanation:
Let's solve your equation step-by-step.
( a − 7 ) ( a + 1 ) = 0
Step 1: Simplify both sides of the equation.
a^2 − 6a − 7 = 0
Step 2: Factor left side of equation.
( a + 1 ) ( a − 7 ) = 0
Step 3: Set factors equal to 0.
a + 1 = 0 or a − 7 = 0
a = −1 or a = 7

Answer: -0.5
Step-by-step explanation:
We can see that at x=0 that Y=2, when x=2, y=1, so we do the x1 - x2 = -2 and y1-y2 = 1
Then we do 1 / -2 = -0.5
The average rate of change is -0.5
Bacteria growth. A colony of bacteria is grown under ideal conditions in a laboratory so that the population increases exponentially with time. At the end of 3 h there are 10,000 bacteria. At the end of 5 h there are 40,000 bacteria. How many bacteria were present initially
Answer:
1250 bacteria
Step-by-step explanation:
The formula for Exponential Growth is given as:
P(t)= Poe^rt
Where
P(t) = Population after time t
Po = Initial Population
r = growth rate
t = time
Hence, solving for the above question , we have to find Po
Making Po the subject of the formula
Po = P(t)/e^rt
Step 1
Find the Exponential growth rate
At the end of 3 h there are 10,000 bacteria.
Hence:
Po = 10000/e^3r.... Equation 1
At the end of 5 h there are 40,000 bacteria.
Po = 40000/e^5r..... Equation 2
Equating both equations together,
10000/e^3r = 40000/e^5r
Hence:
e^5r/e^3r = 40000/10000
e^2r = 4
Take the In of both sides
In (e^2r) =In 4
2r= In 4
r = In 4/2
r = In 2
Step 2
Solve for Po(Initial Population)
Using Equation 2
Po = 40000/e^5r..... Equation 2
r = In2
Po = 40000/e^5 × In 2
Po = 40000/2⁵
Po = 1250 bacteria.
Therefore, they was 1250 bacteria initially

Jillian is incorrect because the shown graph is not a radical function but a logarithmic function instead. Both radical and logarithmic increase for f(x) when x increases as well.
Note that radical functions do not have any asymptotes, that includes vertical and horizontal.
Part BThe shown graph is a logarithmic function. The name already says it. The logarithmic function is part of logarithmic where the equation is
[tex] log_{a}(m) = n[/tex]

Answer:
point A = (3,9)
point D = (9,3)
point B = (6,5)
point C = (5,6)
Step-by-step explanation:
there's not really much to explain so yeah.
so the one located at 3,9 would be A
the one that says 9,3 that would be D
the one that says 6,5 would be B
and 5,6 would be C
Step-by-step explanation:
what u should do is to start from the x axis which is at the bottom so eg u have 4,5...4 would go at the X axis and the 5 would go at the Y axis..so u should always start from the x axis basically

Dado f(x)=14(5−x)2 cual es el valor de F(11)?
What is m angles ABD in the figure shown?
Answer:
∠ ABD = 19°
Step-by-step explanation:
Since AB and BC are congruent, then Δ ABC is isosceles and the base angles are congruent, that is
∠ BAD = ∠ BCD = 71° , thus
∠ ABC = 180° - (71 + 71) ← angle sum of triangle
∠ ABC = 180° - 142° = 38°
DB is an angle bisector , thus
∠ ABD = 0.5 × 38° = 19°

Given:
Radius of circle = 12 units
Area of sector = 24π sq. units.
Central angle = x
To find:
The value of x.
Solution:
We have,
[tex]r=12[/tex]
[tex]A=24\pi[/tex]
[tex]\theta = x[/tex]
We know that, area of a sector is
[tex]A=\dfrac{\theta }{360^\circ}\pi r^2[/tex]
Where, [tex]\theta[/tex] is central angle, r is radius.
[tex]24\pi=\dfrac{x}{360^\circ}\pi (12)^2[/tex]
[tex]24\pi=\dfrac{x}{360^\circ}\pi (144)[/tex]
[tex]\dfrac{24\pi}{144\pi}=\dfrac{x}{360^\circ}[/tex]
[tex]\dfrac{1}{6}=\dfrac{x}{360^\circ}[/tex]
Multiply both sides by 360 degrees.
[tex]\dfrac{1}{6}\times 360^\circ=x[/tex]
[tex]60^\circ=x[/tex]
The value of x is 60 degrees.
Therefore, the correct option is A.

Step-by-step explanation:
Simplify the expressions to put the left and right in the same form. Then compare. If the x-coefficients are the same, there will be 0 or ∞ solutions. If they are different, there will be 1 solution.
If the x-coefficients are the same, look at the constants. If they are different, there will be 0 solutions. If they are the same, there will be ∞ solutions.

7/8 divided by 3/9
please show steps and explain how so i can understand
Answer:
21/8
Step-by-step explanation:
okay so what we have to do is called flip n' multiply, so we leave the first fraction the way it is and the second one, we flip. so instead of 3/9, it would be 9/3. now we just do 7/8 times 9/3 to get 63/24 which I believe will be simplified to 21/8
Answer:
Seven eighths divided by three ninths is equal to twenty-one eights.
Step-by-step explanation:
The easiest way to divide one fraction by another is to simply multiply the first one by the second one. It's that easy:
[tex]\frac{7}{8} \div \frac{3}{9}[/tex]
is exactly the same as:
[tex]\frac{7}{8} \times \frac{9}{3}[/tex]
Which we can then solve by multiplying the numerators by each other and multiplying the denominators by each other
[tex]\frac{7}{8} \times \frac{9}{3}\\\\ = \frac{7 \times 9}{8 \times 3} \\\\ = \frac{63}{24} \\\\ = \frac{21}{8}[/tex]
Another way you can solve it is by noting that in the second number, both the numerator and denominator are divisible by 3, which gives a way to simplify before doing the division:
[tex]\frac{7}{8}\div \frac{3}{9}\\\\= \frac{7}{8}\div \frac{1}{3}\\\\= \frac{7}{8}\times \frac{3}{1}\\\\= \frac{7}{8}\times 3\\\\= \frac{21}{8}[/tex]

Find the range of the function y = 3/4 x + 17 when the domain is -12, -4, 8
Answer:
The range of the function y = 3/4 x + 17 when the domain is -12, -4, 8 is 8,14,23
Step-by-step explanation:
We need to find the range of the function y = 3/4 x + 17 when the domain is -12, -4, 8
Basically, we need to find value of y when x is -12,-4 8
The values of y is the range of the given function.
Put x = -12
[tex]y = \frac{3}{4} x + 17\\y= \frac{3}{4} (-12) + 17\\y=3(-3)+17\\y=-9+17\\y=8[/tex]
When x = -12, y= 8
Put x = -4
[tex]y = \frac{3}{4} x + 17\\y= \frac{3}{4} (-4) + 17\\y=3(-1)+17\\y=-3+17\\y=14[/tex]
When x = -4, y = 14
Put x = 8
[tex]y = \frac{3}{4} x + 17\\y= \frac{3}{4} (8) + 17\\y=3(2)+17\\y=6+17\\y=23[/tex]
So, when x = 8, y = 23
The range of the function y = 3/4 x + 17 when the domain is -12, -4, 8 is 8,14,23
Answer:
The range of the function y = 3/4 x + 17 when the domain is -12, -4, 8 is 8,14,23

Answer:
Each piece would be 1.8 yards, or in fraction form, [tex]1 \frac{4}{5}[/tex].
Step-by-step explanation:
Just turn 14 2/5 into a decimal, which is 14.4. Then, divide it by 8 using a calculator, and 14.4/8 equals 1.8. In fraction form, this is [tex]1 \frac{4}{5}[/tex].
Hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day and good luck with your assignment. :)
Answer:
1.8
Step-by-step explanation:
First, to make this easier, let's turn the fraction to a whole number
14[tex]\frac{2}{5}[/tex] = 14.4
If we want to cut it into 8 equal pieces, let's divide this number by 8
14.4 ÷ 8 = 1.8

How many solutions does the system y = 6x + 6 and y = 6(x + 1) have?
Explain your answer.
Answer:
(-∞,∞)
infinite
Step-by-step explanation:
y= 6x+6; y=6(x+1)
Eliminate the equal sides of each equation and combine
6x+6 = 6(x+1)
solve 6x+6 = 6(x+1) for x
simplify 6(x+1)
apply the distributive property
6x+6 = 6x+ 6*1
multiply 6 by 1
6x+6 = 6x+6
move all terms containing x to the left side of the equation
6=6
and since 6=6, the equation will always be true
The lines y = 6x + 6 and y = 6(x + 1) which consist a system of equation has infinite no. of solutions.
What is the graphical solution of system of equations?Graphical solutions of a system of equations are way of finding the intersection points of all the equations given.
A system with two or more than two equations has a solution only when they have a common intersection point.
Given a system of equation y = 6x + 6 and y = 6(x + 1) ⇒ y = 6x + 6.
As these lines are coinciding to each other so every point of one line lies onto the other therfore they have an infinite no. of solutions.
