Five years from now, a father's age will be tree times his son's age, and 5 years ago, he was seven times as old as his son was. What are their present age?
Answers
Answer:
The answer is "10 and 40".
Step-by-step explanation:
[tex]\to f + 5 = 3(s + 5) = 3s + 15\\\\\to f - 5 = 7(s - 5) = 7s - 35\\\\[/tex]
Subtracting the equations to get
[tex]\to 10 = -4s + 50\\\\\to -40 = -4s\\\\\to s = \frac{40}{4} \\\\\to s=10\\\\\to f = 40\\\\[/tex]
So the Son age is 10, and the father's age is 40.

0.1d +.25 (10) = 12.5 what is d
Answers
Answer:
d = 100
Step-by-step explanation:
0.1d + 0.25(10) = 12.5
0.1d + 2.5 = 12.5
0.1d + 2.5 - 2.5 = 12.5 - 2.5
0.1d = 10
0.1d × 10 = 10 × 10
d = 100

Determine whether the measures 2, √8, and √12 can be the measures of the sides of a triangle. If so, classify the triangle as acute, obtuse,
or right. Justify your answer.
Answers
Answer:
C
Step-by-step explanation:
First check if the triangle is right.
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = [tex]\sqrt{12}[/tex] and ([tex]\sqrt{12}[/tex] )² = 12
2² + ([tex]\sqrt{8}[/tex] )² = 4 + 8 = 12
Thus the triangle is right → C
Answer:
C.
Step-by-step explanation:
Squaring the numbers we get 2^2 = 4, 8 and 12.
Lets look at the relation between 4 8 and 12:-
12 = 4 + 8
- so it obeys the Pythagoras theorem.
It is a right triangle and the answer is C.

What is slope ?slope, Numerical measure of a line's inclination relative to the horizontal. In analytic geometry, the slope of any line, ray, or line segment is the ratio of the vertical to the horizontal distance between any two points on it (“slope equals rise over run”).The equation of a line that passes through points (8, 4) and (0, 2) is .
The equation of the line in Slope-Intercept form is:
y = mx + b ( m - slope)
The equation of the line slope intercept is-
[tex]y - 4 = \frac{1}{4} ( x -8)\\y - 4 = \frac{1}{4} x - \frac{8}{4} \\y - 4 = \frac{1}{4} x - 2\\y = \frac{1}{4} - 2 + 4\\y = \frac{1}{4} x + 2\\[/tex]...................(1)
Now compare equation 1 from y = mx + b
So, m = 1/4 & b = 2
Therefore, The correct option is (3) [tex]y = \frac{1}{4} x + 2[/tex] .

Given:
The given function is:
[tex]f(x)=11x-11[/tex]
To find:
The value of [tex](f\circ f^{-1})(-11)[/tex].
Solution:
We have,
[tex]f(x)=11x-11[/tex]
First we have to find the inverse of this function.
Putting f(x)=y, we get
[tex]y=11x-11[/tex]
Interchange x and y.
[tex]x=11y-11[/tex]
Isolate the variable y.
[tex]x+11=11y[/tex]
[tex]\dfrac{x+11}{11}=y[/tex]
[tex]y=\dfrac{x+11}{11}[/tex]
Putting [tex]y=f^{-1}(x)[/tex], we get
[tex]f^{-1}(x)=\dfrac{x+11}{11}[/tex]
Now,
[tex](f\circ f^{-1})(-11)=f(f^{-1}(-11))[/tex]
[tex](f\circ f^{-1})(-11)=f\left(\dfrac{-11+11}{11}\right)[/tex] [tex]\left[\because f^{-1}(x)=\dfrac{x+11}{11}\right][/tex]
[tex](f\circ f^{-1})(-11)=f\left(\dfrac{0}{11}\right)[/tex]
[tex](f\circ f^{-1})(-11)=f\left(0\right)[/tex]
The given function is [tex]f(x)=11x-11[/tex].
[tex](f\circ f^{-1})(-11)=11(0)-11[/tex]
[tex](f\circ f^{-1})(-11)=-11[/tex]
Therefore, the value of [tex](f\circ f^{-1})(-11)[/tex] is [tex]-11[/tex]. Hence the correct option is A.
