Determine whether the functions f(x) = -7/5x +4/5 and g(x) = x – 4 intersect at x = 2.
A.No, because f (2) #g(2) when r =
B. No, because f (0) = 9(2) when I = 2.
C. Yes, because f(x) + 9(2) when r = 2.
D. Yes, because f(x) = 9(2) when I = 2.
Answer:
D. Yes, because f(x) = g(x) when x = 2.Step-by-step explanation:
Given the functions f(x) = -7/5x +4/5 and g(x) = x – 4, for the functions to intersect, f(x) must be equal to g(x) i.e f(x) = g(x) at x = 2
-7/5x +4/5= x- 4
If x = 2
f(2) = -7/5 (2)+ 4/5
f(2) = -14/5 + 4/5
f(2) = -10/5
f(2) = -2
g(x) = x - 4
g(2) = 2-4
g(2) = -2
Since f(2) = g(2), hence the lines intersects at x = 2

Answer:
30 inches jrjdbdbrbejjr
simplifyyyyyyyyyyyyyyyyyy
Answer:
Step-by-step explanation:
x^2 - 11x + 30 = (x - 6)(x - 5)
x^2 - 4 = (x + 2)(x - 2)
x^2 + 3x - 40 = (x + 8)(x - 5)
x - 2 = x - 2
Invert and multiply the right fraction.
(x - 6)(x - 5) (x - 2)
=========== x =======
(x - 2)(x + 2) (x + 8)(x - 5)
x - 5 on the top cancels with x - 5 on the bottom
x - 2 on the top cancels with x - 2 on the bottom left

Which statements represent the relationship between y=3x and y=log3x ?
a. The graphs of functions are symmetric about the line y = 0.
b. The functions are inverses of each other.
c. The graphs of functions are symmetric to each other over the line y = x.
d. The equation y=log3x is the logarithmic form of y=3x .
2 Answers: Choice B and Choice C
====================================================
Explanation:
Choice A is false because all of [tex]y = 3^x[/tex] is above the x axis. There are no portions below the x axis, which means it cannot possibly be symmetric about the x axis.Choice B is true. The exponential undoes the log, and vice versa. This only works if the bases of the exponential and log are the same. In this case, both are base 3.Choice C is true. To visually find the inverse, we reflect over the line y = x.Choice D is false. Converting [tex]y = 3^x[/tex] to logarithmic form leads to [tex]x = \log_3(y)[/tex]. So you'll need to swap the x and y.Write the formula to calculate the area of a triangle whose sides are unequal in length

Find the mean, median, and mode of the data set 8 2 7 2 6 5
Answer:
Mean is 6, median 5.5, mode 2
Step-by-step
Answer:
mean=8+2+7+2+6+5
=30
30÷6=5
note: divide the total with it's sum.
median=7+2
=9
9÷2= 4.5
note: median is the middle no. since there is no middle no. so just add those two no. and divide it by 2.
mode= 2
since it occurs twice
Aaliyah is working two summer jobs, making $7 per hour walking dogs and making $10 per hour tutoring. In a given week, she can work no more than 17 total hours and must earn no less than $140. Also, she must work at least 2 hours walking dogs and at most 13 hours tutoring. If xx represents the number of hours walking dogs and yy represents the number of hours tutoring, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
140 >/ 7x + 10y (read as 140 is greater than or equal to 7x plus 10y)
x + y /< 17 - to represent the number of hours she can work
she will work at least 10 hours walking dogs and at least 7 tutoring

Gene paid a deposit on a leased car. The deposit earns 2.8 percent simple annual interest. At the end of the year, the interest that is earned is $22.40. What was the amount of the original deposit?
Answer:
The original amount was: P = $800
Step-by-step explanation:
Given
Interest I = $22.40
Interest rate = r = 2.8% = 0.028
time t = 1 year
Using the interest formula
I = Prt
I = InterestP = Principle or initial valuer = interest rate t = time (years)substituting the values
I = Prt
22.40 = P (0.028) (1) ∵ I = 22.40, r = 2.8% = 0.028, t = 1
P = 22.40 / 0.028
P = $800
Therefore, the original amount was: P = $800
it's D (800.00)

Which graph below represents the solution to the inequality 6 x − 12 − x ≤ 3
Answer:
The solution is:
[tex]6x-12-x\le \:3\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:3\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:3]\end{bmatrix}[/tex]
The graph of the solution is attached below.
Both the number line and graph is attached below.
Step-by-step explanation:
Note: you missed to add the graph options. Therefore, I am solving the inequality and adding the corresponding graph which would anyways clear your concept.
Given the inequality expression
[tex]6\:x\:-\:12\:-\:x\:\le \:3[/tex]
Group like terms
[tex]6x-x-12\le \:3[/tex]
Add similar elements: 6x-x=5x
[tex]5x-12\le \:3[/tex]
Add 12 to both sides
[tex]5x-12+12\le \:3+12[/tex]
simplify
[tex]5x\le \:15[/tex]
Divide both sides by 5
[tex]\frac{5x}{5}\le \frac{15}{5}[/tex]
simplify
[tex]x\le \:3[/tex]
Therefore, the solution is:
[tex]6x-12-x\le \:3\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:3\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:3]\end{bmatrix}[/tex]
The graph of the solution is attached below.Both the number line and graph is attached below.

There are 48 candies in a pack. Twelve are red. 18 are yellow. What is the ratio of reds to yellows?
Answer is 5:3
This means the ratio of reds to yellows is 5 to 3
=========================================================
Work Shown
We have 48 candies total and 18 yellow. This means there are 48-18 = 30 red assuming there are no other colors.
The ratio of red to yellow is 30:18. We simply list the number of reds (30), followed by a colon, then the number of yellows.
(number of red):(number of yellow)
The order is important. We cannot swap the items. This is because "reds to yellows" in the instructions has "red" come first.
Once you have the ratio 30:18, you divide both parts by the GCF 6 and you'll end up with the final answer 5:3
So for every 5 red candies we have 3 yellow candies. We can say "the ratio of reds to yellows is 5 to 3".

sin θ = 12/37. Find tan θ.
Answer:
B
Step-by-step explanation:
Use SOHCAHTOA.
sinθ = [tex]\frac{opposite}{hypotenuse}[/tex]
Opposite side length= 12
Hypotenuse length = 37
Find the adjacent side length (b) using the Pythagorean theorem.
[tex]12^2 + b^2 = 37^2[/tex]
b = 35
tanθ = [tex]\frac{opposite}{adjacent}[/tex] = 12/35
Choice B is the correct answer.
Answer:
Step-by-step explanation:
using sin inverse rule to get theta
[tex]sin^{-1} (\frac{12}{37} ) =18.9246[/tex] <---- theta
so tan(18.9246) =12 /35
