Answer:
7. x = 23
Step-by-step explanation:
They are angles on transversals intersecting parallel lines. Also vertical angels are equal to each other.
So for example question 7 you need to use these two things to realize that 4x is the same angle as (3x + 23) so you have to put them in an equation like this
4x = 3x + 23 and then solve it algebraically
Without graphing, determine whether the system of linear equations has one solution, infinitely many solutions, or no solutions.
y=6x+2y=6x+2 and y=6x-4y=6x−4
Answer:
The system has no solutions.Step-by-step explanation:
y = 6x + 2 ⇒ 6x - y = -2
y = 6x - 4 ⇒ 6x - y = 4
a₁ = a₂ = 6 , b₁ = b₂ = -1 , c₁ = -2 , c₂ = 4
a₁ = a₂ = 6 and b₁ = b₂ = -1 and c₁ ≠ c₂ ⇒ NO SOLUTIONS

Which scatterplot shows a linear association?
Answer:
A scatter plot shows the association between two variables. A scatter plot matrix shows all pairwise scatter plots for many variables. If the variables tend to increase and decrease together, the association is positive. If one variable tends to increase as the other decreases, the association is negative.

Answer:
1) option b ---> (-3, -5)
2) option a ---> (8, 6)
3) option a ---> (5, 8)
Step-by-step explanation:
1) (3, -5) reflection over the y-axis.
According to the rule of reflection over the y-axis :-
(x, y) ---> (-x, y)
(3, -5) ---> (-3, -5)
2) (-6, 8) rotate 90⁰ clockwise.
According to the rule of rotating 90⁰ clockwise :-
(x, y) ---> (y, -x)
(-6, 8) ---> (8, 6)
*Since x was a negative it becomes positive.*
3) (7, 4) translate 2 unit left and 4 units up.
According to the rule of translation :-
(x, y) ---> (x - 2, y + 4)
(7, 4) ---> ( 7 - 2, 4 + 4)
(7, 4) ---> (5, 8)

How to round 8.6023 in the nearest tenth?
Answer:
8.6
Step-by-step explanation:
https://www.you.tube.com/watch?v=32gDF10ZXOA
( it might be wrong pls dont report me just let me kno y its wrong )
Answer:
8.6
Step-by-step explanation:
First of all consider the thousands in the decimal which is 2. Since 2 is not greater than 5 we have to remove the number 2 and 3 from the 8.6023.
We're left with 8.60. Now we see that there's a 0 in the hundredths so since it's not greater than 5 we remove it.
Now we're left with 8.6 which is to the nearest tenth.

How would you interpret the statement that b (14)=170
Answer:
B= 12.14
14 multiplied by B= 170
170/14 = 12.14
Step-by-step explanation:
+ 6x + 7 + 6x + 9 = (6x + 7) + (6x + 9) = 6x + (7 + 6x) +9 = 6x + (6x + 7) + 9 = (6x + 6x) + (7 + 9) = (6 + 6)X + (7 + 9) = 12x + 16
Answer:
6 x − 7 = 9 6x-7=9 6x−7=9. 6x-7=9. 6x-7=9. 6x-7=9. 1. Add 7 7 7 to both sides. 6 x = 9 + 7 6x=9+7 6x=9+7. 2. Simplify 9 + 7 9+7 9+7 to 16 16 16. 6 x = 16 6x=16

What is the measure of the smaller of two complementary angles if one angle is 4x and the other is 2x + 18?
Answer:
42°
Step-by-step explanation:
4x + 2x + 18 = 90 because they are complementary angles (add up to 90°)
reduce:
6x = 72
x = 12
one angle = 4(12) = 48°
other angle = 2(12) +18 = 42°

María tiene en su libreta de ahorros un capital de 123.000,si deposita el día lunes la cantidad de 12.670 .El día miércoles por una urgencia , realiza un giro de 56.000¿cual es el nuevo capital que posee? Escribe la operación utilizando números enteros
Answer:
$79.670.
Step-by-step explanation:
Dado que María tiene en su libreta de ahorros un capital de $ 123.000,si deposita el día lunes la cantidad de $12.670, y el día miércoles por una urgencia, realiza un giro de $56.000, para determinar cuál es el nuevo capital que posee se debe realizar el siguiente cálculo:
123.000 + 12.670 - 56.000 = X
135.670 - 56.000 = X
79.670 = X
Así, el nuevo capital que María posee en su cuenta es de $79.670.

Determine whether each expression is equivalent to 100t^2-0.5t
Answer:
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{10^{t^{2}}}{100^{t}}[/tex].
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}}\cdot 2^{t^{2}}}{25^{0.5\cdot t}\cdot 4^{0.5\cdot t}}[/tex].
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}-0.5\cdot t}}{5^{t^{2}-0.5\cdot t}}[/tex].
Step-by-step explanation:
The expression to be evaluated is [tex]100^{t^{2}-0.5\cdot t}[/tex], we find by algebraic means the equivalent expression:
Possibility 1:
[tex]100^{t^{2}-0.5\cdot t}[/tex]
[tex]\frac{100^{t^{2}}}{100^{0.5\cdot t}}[/tex]
[tex]\frac{100^{t^{2}}}{(100^{0.5})^{t}}[/tex]
[tex]\frac{100^{t^{2}}}{10^{t}}[/tex]
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{10^{t^{2}}}{100^{t}}[/tex].
Possibility 2:
[tex]100^{t^{2}-0.5\cdot t}[/tex]
[tex]\frac{100^{t^{2}}}{100^{0.5\cdot t}}[/tex]
[tex]\frac{(50\cdot 2)^{t^{2}}}{(25\cdot 4)^{0.5\cdot t}}[/tex]
[tex]\frac{50^{t^{2}}\cdot 2^{t^{2}}}{25^{0.5\cdot t}\cdot 4^{0.5\cdot t}}[/tex]
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}}\cdot 2^{t^{2}}}{25^{0.5\cdot t}\cdot 4^{0.5\cdot t}}[/tex].
Possibility 3:
[tex]100^{t^{2}-0.5\cdot t}[/tex]
[tex]\left(\frac{500}{5} \right)^{t^{2}-0.5\cdot t}[/tex]
[tex]\frac{500^{t^{2}-0.5\cdot t}}{5^{t^{2}-0.5\cdot t}}[/tex]
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}-0.5\cdot t}}{5^{t^{2}-0.5\cdot t}}[/tex].
In kite PQRS, m_OPO = 50° and m_ORO = 70°. Find m2PSR
Answer:
m<PSR = 60°
Step-by-step explanation:
Given:
m<OPQ = 50°
m<ORQ = 70°
Required:
m<PSR
Solution:
m<PQR + m<OPQ + m<ORQ = 180° (Sum of triangle)
m<PQR + 50 + 70 = 180 (Substitution)
m<PQR + 120 = 180
m<PQR = 180 - 120
m<PQR = 60°
One of the properties of a kite states that the angles where the unequal sides meets are congruent to each other. Therefore:
m<PSR = m<PQR
m<PSR = 60° (substitution)
