Answer:
t = -11
Step-by-step explanation:
Solve for t:
-3 t - 8 = 25
Add 8 to both sides:
(8 - 8) - 3 t = 8 + 25
8 - 8 = 0:
-3 t = 25 + 8
25 + 8 = 33:
-3 t = 33
Divide both sides of -3 t = 33 by -3:
(-3 t)/(-3) = 33/(-3)
(-3)/(-3) = 1:
t = 33/(-3)
The gcd of 33 and -3 is 3, so 33/(-3) = (3×11)/(3 (-1)) = 3/3×11/(-1) = 11/(-1):
t = 11/(-1)
Multiply numerator and denominator of 11/(-1) by -1:
Answer: t = -11
[tex] - 3t + ( - 8) = 25[/tex]
Distribute the plus/positive in the negative. Remember that plus × minus = minus.[tex] - 3t - 8 = 25[/tex]
Solve for t-term by making t as the subject of equation.[tex] - 3t = 25 + 8 \\ - 3t = 33 \\ t = \frac{33}{ - 3} \longrightarrow \frac{ \cancel{33}}{ \cancel{ - 3} } = \frac{11}{ - 1} \\ t = - 11[/tex]
Answer Check by substituting the value of t in the equation.[tex] - 3( - 11) + ( - 8) = 25 [/tex]
Distributing or multiplying both negative, we would get positive.
[tex]33 - 8 = 25 \\ 25 = 25 \: \: \purple{ \checkmark}[/tex]
The equation is true for t = -11. Hence the answer is t = -11.
Answer[tex] \large \boxed{t = - 11}[/tex]

3. Resuelve el triángulo con A = 30º, a = 3 cm y b = 4 cm y comprueba que hay dos soluciones posibles.
Answer:
41.8°
Step-by-step explanation:
Resolvemos esta pregunta usando la regla del seno
a / sin A = b / sin B
Estamos despejando el ángulo B
Por lo tanto:
3 / sin 30 = 4 / sin B
Cruz multiplicar
3 × sin B = sin 30 × 4
sin B = sin 30 × 4/3
B = arco sin [sin 30 × 4/3]
B = 41.81031 °
Aproximadamente = 41.8 °

Find the slope of the line that passes through (-10,5) and (-10,8).
Answer:
undefined
Step-by-step explanation:
Since the x value is the same, it looks like the slope is undefined.
Answer: The slope is undefined
Step-by-step explanation:
Find the difference in the y coordinates and divide it by the difference in the x coordinates
y coordinates : 5 - 8 = -3
x coordinates: -10 -(-10) = 0
slope: -3/0 = 0

Help me with geometry this is my 3rd time asking
Answer:
The coordinates of D(5,2)
Step-by-step explanation:
Step(i):-
Given point C(1,-4) and mid point M( 3,-1)
we have to use mid-point formula
[tex](\frac{x_{1}+x_{2} }{2} ,\frac{y_{1}+y_{2} }{2} )[/tex]
Step(ii):-
Given mid point M( 3,-1) and (x₂ , y₂ ) be the 'D' co-ordinates
[tex](\frac{1+x_{2} }{2} ,\frac{-4+y_{2} }{2} ) = (3,-1)[/tex]
⇒ [tex]\frac{1+x_{2} }{2} = 3[/tex] and [tex]\frac{-4+y_{2} }{2} = -1[/tex]
1 + x₂ = 3 ˣ 2 and -4 +y₂ = -2
⇒ x₂ = 6-1 =5 and y₂ = -2 +4
⇒ x₂ = 5 and y₂ = 2
Final answer:-
The coordinates of 'D' = (5,2)

Trying to factor as a Difference of Cubes
2.1 Factoring: 8x2y3-5
Theory : A difference of two perfect cubes, a3 - b3 can be factored into
(a-b) • (a2 +ab +b2)
Proof : (a-b)•(a2+ab+b2) =
a3+a2b+ab2-ba2-b2a-b3 =
a3+(a2b-ba2)+(ab2-b2a)-b3 =
a3+0+0+b3 =
a3+b3
Check : 8 is the cube of 2
Check : 5 is not a cube !!
Ruling : Binomial can not be factored as the difference of two perfect cubes
Final result :
8x2y3 - 5

y = x² + 10x + 25
Answer:
you can use interent mircosoft calculator
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
y = x² + 10x + 25 ← is a perfect square
y = (x + 5)²
To find the solution let y = 0 , that is
(x + 5)² = 0, that is
x + 5 = 0 ⇒ x = - 5

The robotics club is selling shirts for a fundraiser. They have purchased a box of shirts for $400 at $5 per shirt. To promote their fundraiser, they have also spent $60 on advertising.
Answer:
80x-460=300
80x=760
Step-by-step explanation:
In order to know which equation is best, you have to add the total expenses the robotics club had.
Expenses:
box of shirts = $400advertising = $60Let's add: $400 + $60 = $460
Next, you have to know how many of the shirts were purchased.
$400 ÷ $5 = 80Now, let's compute.
80x - 460 = 30080x = 300 + 46080x = 760x = $9.5or
80x=760x = 760 ÷ 80x = $9.5This means that the robotics club has to sell the shirts at $9.5 each in order to have a $300 profit.
