2. Given that 5x² - 7x + 3 = A(x - 1)(x - 2) + B(x - 1) + C for all values of x, find the values of A, B, and C!
Penjelasan dengan langkah-langkah:
5x²-7x+3= A(x²-3x+3)+BX-B+C
5x²-7x+3= Ax²-3Ax+Bx+3A-B+C
maka A = 5
maka 3A-B= 7
3(5)-B= 7
B= 8
maka 3A-B+C= 3
= 15-8+C= 3
maka C= -4
maka (A,B,C)---> (5,8,-4)✓

4. determine the range of values for which the following inequalities are true: a. x + 2 > 10 b. x < 2x - 12 c. 3x + 5 greater than or aqual to 2x - 4
a. x > 10-2
x > 8
b. x-2x < -12
-x < 12
x < 12
5. The range of values of x + 1 < 14 and 2x + 3 > 11 is...
Jawaban:
4<x<11 or (4, 11)
Penjelasan dengan langkah-langkah:
x+1 < 14
x < 14 - 1
x < 13
2x + 3 > 11
2x > 8
x > 8/2
x > 4
so, the solution is
4<x<13
or another writing
(4, 13)
Jawab:
{5, 6, 7, 8, 9, 10, 11, 12}
Penjelasan dengan langkah-langkah:
x + 1 < 14
= x < 13 (x is smaller than 13)
&
2x + 3 > 11
= 2x > 8
= x > 4 (x is bigger than 4)
Then we can say that x is bigger than 4 and smaller than 3, therefore we can simplify it as the inequality below:
4 < x < 13
And the range of possible values of x will be {5, 6, 7, 8, 9, 10, 11, 12}
Hope this helps :D

7. Math ➡️ Ghow to choose x values for graphing quadratic polynomial
First, we should know about the properties of the quadratic equation.
It is better for us to choose x pairing side by side, left and right from symetrical axis of the equation.
So our graph will be including its maximum or minimum point.
(sampai titik di atas jumlah kata yang tercantum hanya 43, itu melanggar ketentuan menjawab soal): padahal saya yakin mbak Diva sudah cukup paham untuk pemilihan nilai x nya.
Karena itu akan saya tambahkan sedikit kata-kata untuk melengkapi jawaban di atas dengan:
gunakan formula x=-b/2a untuk mencari nilai sumbu simetrinya.

8. (x - 5)² + a = x² + bx + 28 Work out the values of a and b.
Jawaban:
a=3
b=-10
Penjelasan dengan langkah-langkah:
(x - 5)² + a = x² + bx + 28x² - 10x + 25 + a = x² + bx + 28a25 + a = 28
a = 28 - 25
a = 3

Jawab:
Penjelasan dengan langkah-langkah:
[tex]f(x) = a(x+1)^2+8+2k[/tex]
[tex]f'(x) = 0 = 2a(x+1) \to a = 0\cup x = -1 \to x = -1, a\neq 0\\f(-1) = 12 = a(0)^2+8+2k\to k = 2\\f(x) = a(x+1)^2+12[/tex]
a)
[tex]f''(x) \equiv 2a > 0\to \boxed{\boxed{a > 0}}[/tex]
b)
[tex]f(x) = a(x+1)^2+12 = a(x-(-1))^2+12\to \boxed{\boxed{x_p = -1}}[/tex]
c)
[tex]f'(x) = 0 = 2a(x+1) \to a = 0\cup x = -1 \to x = -1, a\neq 0\\f(-1) = 12 = a(0)^2+8+2k\to \boxed{\boxed{k = 2}}[/tex]

20. If (ax + 2)(bx + 7) = 15x2 + 2x + 14 for all values ofx, and a + b = 8, what are the two possiblevalues for c ?
Penjelasan dengan langkah-langkah:
First we can expand the left hand side:
(ax+2)(bx+7)abx2+2bx+7ax+14abx2+(7a+2b)x+14=15x2+cx+14=15x2+cx+14=15x2+cx+14
We can equate coefficients to see that
ab7a+2b=15=c(x2)(x)
We can say that
a+ba=8=8−b
And thus
ab(8−b)b8b−b2b2−8b+15(b−5)(b−3)=15=15=15=0=0
So we can say b=3 or b=5
When b=3, then a=5 and we can say that
c=7a+2b=7×5+2×3=35+6=41
When b=5, then a=3 and we can say that
c=7a+2b=7×3+2×5=21+10=31
So, the two values of c are 41 and 31
