Las edades de cuatro hermanos forman una progresión aritmética, y su suma es 32 años. El mayor tiene 6 años más que el menor. Halla las edades de los cuatro hermanos.
Answer:
The ages of the four siblings are: 5, 7, 9 and 11 years old.
Step-by-step explanation:
The computation of the age of the four siblings is shown below:
Given that
n = 4
a1 =? a2 =? a3 =? a4 =?
a4 = a1 + 6 years
S4 = 32
Based on the above information
As we know that
Sn = (a1 + a4) × n ÷ 2
S4 = (a1 + a4) × 4 ÷ 2
32 = (a1 + a1 +6) × 2
16 = 2a1 + 6
2a1 = 10
a1 = 10 ÷ 2
= 5
So, a4 = a1 +6
= 5 +6
= 11
a4 = a1 + (4-1) × d
11 = 5 + 3 × d
d = 6 ÷ 3
= 2
So,
a2 = a1 + d
= 5 + 2
= 7
a3 = a2 + d
= 7 + 2
= 9
Hence, The ages of the four siblings are: 5, 7, 9 and 11 years old.

Which function is equivalent to y = 2(x – 4)^2 + 8?
A. y= 2x² + 24
B y=2x^2 – 16x + 40
C y= 2x^2 – 16x +48
D y=2x² – 8x + 24
Answer:
B: y = 2x² - 16x + 40
Step-by-step explanation:
You can find this simply by expanding the given function:
y = 2(x - 4)² + 8
y = 2(x² - 8x + 16) + 8
y = 2x² - 16x + 32 + 8
y = 2x² - 16x + 40

HI PLEASE HELP I WILL GIVE BRAINLEIST
PLEASE SHOW ME THE WORKINGS
Answer:
see explanation
Step-by-step explanation:
Expand the factored form and compare coefficients of like terms with the original polynomial
a(x + 1)(x - 2)² + b(x + 2) + c
= a(x + 1)(x² - 4x + 4) + b(x + 2) + c
= a(x³ - 4x² + 4x + x² - 4x + 4) + b(x + 2) + c
= a(x³ - 3x² + 4) + b(x + 2) + c ← distribute parenthesis
= ax³ - 3ax² + 4a + bx + 2b + c
Compare x³ terms
ax³ with 2x³ , then a = 2
Compare x terms
bx = - 3x , then b = - 3
Compare constant terms
4a + 2b + c = 6
4(2) + 2(- 3) + c = 6
8 - 6 + c = 6
2 + c = 6 ( subtract 2 from both sides )
c = 4
Thus a = 2, b = - 3, c = 4

Answer:
y = 3/4x -7/4 or y = 0.75x -1.75
Step-by-step explanation:
The two point form of the equation of a line is useful when you are given 2 points and asked for the equation.
y = (y2 -y1)/(x2 -x1)·(x -x1) +y1
y = (35 -14)/(49 -21)·(x -21) +14 . . . . . . fill in given points
y = 21/28(x -21) +14 . . . . . . . . . . . . . . . simplify a bit
y = 3/4(x -21) +14 . . . . . . . . . . . reduce the fraction
y = 3/4x -15 3/4 +14 . . . . . . . .eliminate parentheses
y = 3/4x -7/4 or y = 0.75x -1.75
