Step-by-step explanation:
w = 3(2a + b) - 4
w = 6a + 3b - 4
6a = w - 3b + 4
a = 1/6 * (w - 3b + 4).

Order the polynomial -x 4 y 2 + 7x 3 y 3 - 3xy 5 + 2x 2 y 4 in descending powers of x.
Answer:
See under for the sequence
Step-by-step explanation:
The term with -X⁴ comes first because 4 is the highest power of x.
Then comes 7x³y³ because 3 is the second highest power
Then 2x²y⁴ because 2 comes next
Then -3xy⁵ because x is raised to 1 power which is the lowest

If the same side interior angles is not supplementary why do we know that the lines are not parallel
I need help
Answer:
The same-side interior angle theorem states that when two lines that are parallel are intersected by a transversal line, the same-side interior angles that are formed are supplementary, or add up to 180 degrees

Answer:
The missing angle is about 27.92°.
Step-by-step explanation:
This is a tangent equation, as there is no hypotenuse value. I'll use x as the missing angle.
tan(x) = opposite/adjacent
tan(x) = 20/38
tan(x) = 0.52631578947368421052631578947368
tan(x) ≈ 0.53
Now, we have to reverse.
tan⁻¹(0.53) = x
27.92358972 = x
x ≈ 27.92°
How many solutions are there to the equation shown below? 7x+12=5x−8
Answer:
Only one and that one solution is -10
Step-by-step explanation:
;w;
Answer:
One Solutionx = -10Explanation:
7x + 12 = 5x − 8
Subtract 12 from both sides7x + 12 - 12 = 5x - 8 + 12
Simplify7x = 5x - 20
Subtract 5x from both sides7x - 5x = 5x - 20 - 5x
Simplify2x = -20
Divide both sides by 22x / 2 = -20 / 2
Simplifyx = -10There Is One solution- PNW

Move words to the blanks and equations to the boxes to prove that vertical angles <21 and <23 are congruent.
Answer:
See proof below
Step-by-step explanation:
From the given diagram, we can see that <2 and <3 lies on the same straight line, hence the sum of the angles is 180 degrees (supplementary)
<2 + <3 = 180 .... 1
Similarly. <1 and <2 are also supplementary angles
<1 + <2 = 180 .... 2
Subtract 1 from 2;
<3 - < 1 + <2 - <2 = 180 - 180
<3 - <1 +0 = 0
<3 - <1 = 0
Add <1 to both sides
<3 - <1 + <1 = 0+<1
<3 = <1 (Proved!)
This shows that <3 and <1 are equal
We can also conclude that <3 and <1 are vertically opposite angles and vertically opposite angles are equal
How many points does the team have?
How many games has this team lost?
Step-by-step explanation:
P = 3W + D
When W = 5 and D = 3, P = 3(5) + 3 = 18.
When P = 50 and D = 14,
(50) = 3W + (14), 3W = 36, W = 12.
Since the team has 12 wins and 14 draws,
they have 35 - 12 - 14 = 9 losses.
Una nadadora entrenó todos los días durante 21días. El primer día nadó 15 minutos, y cada día nadaba 5 minutos más que el día anterior. ¿Cuánto tiempo nadó el último día? ¿Y a lo largo de las tres semanas? Expresa los resultados en horas y minutos.
Responder:
1 hora 55 minutos; 22 horas 45 minutos
Explicación paso a paso:
Dado que:
Tiempo el primer día = 15 minutos
Minutos adicionales cada día siguiente = 5 minutos
Número total de días
Usando la fórmula del enésimo término de una progresión aritmética:
Tn = A + (n - 1) d
A = primer trimestre = 15
d = diferencia común = 5
n = enésimo término
Tiempo de nado el último día (n = 21)
T21 = 15 + (21 - 1) 5
T21 = 15 + 20 * 5
T21 = 15 + 100
T21 = 115 minutos
= 1 hora 55 minutos
SEGUNDO.)
Suma de minutos durante las 3 semanas
Suma de n términos:
Sn = n / 2 * (primer término + último término)
Primer término = 15
Último trimestre = a21 = 115 minutos
n = número de términos = 21
Por lo tanto,
Sn = 21/2 * (15 + 115)
Sn = 10,5 * (130)
Sn = 1365 minutos
= 22 horas 45 minutos

Answer:
Yes, this set of lengths can form a triangle.
Step-by-step explanation:

Answer:
The function y = 5 [tex](.98)^{x}[/tex] represents exponential decay
The percentage rate of change is 2%
Step-by-step explanation:
The formula of the exponential growth is y = a [tex](1+r)^{x}[/tex], where
a is the initial valuer is the rate of increase in decimal ⇒ (1 + r) > 1The formula of the exponential decay is y = a [tex](1-r)^{x}[/tex], where
a is the initial valuer is the rate of decrease in decimal ⇒ (1 - r) < 1Let us solve the question.
∵ y = 5 [tex](.98)^{x}[/tex]
→ Compare it with the forms above
∴ a = 5
∵ The rate of change is .98
∵ .98 < 1
→ That means the rate of change is decreasing
∴ The function y = 5 [tex](.98)^{x}[/tex] represents exponential decay
→ From the 2nd form above
∵ (1 - r ) = .98
→ Subtract 1 from both sides
∴ 1 - 1 - r = .98 - 1
∴ - r = - .02
→ Divide both sides by -1
∴ r = .02
→ Multiply it by 100% to change it to a percentage
∵ .02 × 100% = 2%
∴ r = 2%
∴ The percentage rate of change is 2%
