1. Let the function f be defined by f(x) = 5x – 2a, where a is a constant. Iff(10) + f(5) = 55 what is the value of a.
Jawaban:
a = 5
Penjelasan dengan langkah-langkah:
f(x) = 5x - 2a
f(10) + f(5) = 55
(5(10)-2a) + (5(5)-2a) = 55
50-2a + 25-2a = 55
50 + 25 - 4a = 55
75 - 55 = 4a
20 = 4a
5 = a
a = 5
so the value of a is 5

3. A function is defined by the formula f(x) = ax + b. if f (4) = 5 and f (-2) = 7 Find : a. the value of a and b b. the function formula tolongin yaa :D
Diketahui sebuah Fungsi dengan :
f(x) = ax + b
f(4) = 4a + b = 5......(1)
f(-2)= -2a + b =7......(2)
Ditanay = a?, b?, Fungsi Persamaan?
Carilah Hasil A dan B dari (1) dan (2) dengan cara menguranginya
4a-(-2a) +b - b = 5-7
6a= -2
a= (-1/3)
b= 4× (-1/3) +b =5
-4/3-5= -b
b = 4/3 + 5 = 19/3

4. Let f(x)=3x^2+5. The quadratic function g(x) is f(x)translated 3 units up.
Jawaban:
g(x) = 3x^2+18x+32
Penjelasan dengan langkah-langkah:
g(x)= 3(x+3)^2+5
= 3(x^2 + 6x +9)+5
= 3x^2 + 18x +27 +5
= 3x^2 + 18x + 32

8. 10. A function is defined by the formula f(x) = ax + b. If f(3) = 15 and f(5) = 20. Find: a) the value of a and b b) f(-2) 11. Two pensils and one eraser cost Rp. 35.000 and 3 pencils and four erasers cost Rp. 65.000 Find the cost of a pencil and two erasers!
10) f(x) = ax + b
f(3) = 15
f(3) = a(3) + b
15 = 3a + b
f(5) = 20
f(5) = a(5) + b
20 = 5a + b
a) 3a + b = 15
5a + b = 20
Kedua persamaan ini dikurangi, maka :
-2a = -5
a = 5/2
Masukin ke persamaan :
3a + b = 15
3(5/2) + b = 15
15/2 + b = 15
b = 15 - 15/2
b = 30/2 - 15/2
b = 15/2
b) f(x) = ax + b
f(-2) = 5/2(-2) + 15/2
= -10/2 + 15/2
= 5/2
11) Pencil (a)
Eraser (b)
2a + b = 35.000
3a + 4b = 65.000
a + 2b =?
2a + b = 35.000 | x 4 | 8a + 4b = 140.000
3a + 4b = 65.000 | x 1 | 3a + 4b = 65.000
Kedua persamaan ini dikurangi, maka :
5a = 75.000
a = 15.000
Masukin ke persamaan :
2a + b = 35.000
2(15.000) + b = 35.000
30.000 + b = 35.000
b = 5.000
Maka a + 2b
= 15.000 + 2(5.000)
= 15.000 + 10.000
= 25.000
9. A function f is defined by f:x --> 5-2 sin 2x for 0 <= x <= π . Solve the equation f(x) = 6 , giving answers in terms of π
f(x) = 5 - 2 sin 2x ; 0 ≤ x ≤ π
f(x) = 6
5 - 2 sin 2x = 6
-2 sin 2x = 1
sin 2x = -½
Notice that the interval is 0 ≤ x ≤ π, which is in quadrant I and quadrant II. Because the value of sin x is negative, then x is in quadrant III and quadrant IV. Therefore, none of the x values are satisfactory. Or it can be said that the solutions for the above equation does not exist.

17. apa figurative language dari lagu " let it be by The Beatles "
The only figurative language I recognize in it is that McCartney is not necessarily talking about “Mother Mary” in the religious sense of the mother of Jesus. His own mother was named Mary (who died when he was young), so it carries a double meaning for him. I think that is typical Beatles doublespeak.
The rest of the lyrics are straightforward, referring to conflict and resolution personally and in the world in general.
