Answer:
(−2, −8)
Step-by-step explanation:
Write the problem as a mathematical expression.
y = 7x + 6
4x − 3y = 16
Replace all occurrences of y in 4x − 3y = 16 with 7x + 6. 4x − 3 (7x + 6) = 16
y = 7x + 6
Simplify 4x − 3 (7x + 6).
−17x − 18 = 16
y = 7x + 6
Solve for x in the first equation.
Move all terms not containing x to the right side of the equation.
−17x = 34
y = 7x + 6
Divide each term by −17 and simplify.
x = −2
y = 7x + 6
Replace all occurrences of x with −2 in each equation.
Replace all occurrences of x in y = 7x + 6 with −2. y = 7 (−2) + 6
x = −2
Simplify 7 (−2) + 6.
y = −8
x = −2
The solution to the system is the complete set of ordered pairs that are valid solutions.
(−2, −8)
The result can be shown in multiple forms.

Step-by-step explanation:
Isabela tem dois dados de um jogo, conforme a figura a seguir: O dado 1 é numrado de 1 a 6 e o dado 2 é numerado de 1 a 8. Isabela lançou os dois dados simultaneamente. A probabilidade de que a soma obtida pelos dois números sorteados seja maior que dez é de, aproximadamente: A) 14% B) 15% C) 21% D) 27% E) 29%
Responda:
C) 21%
Explicação passo a passo:
Dado que:
Dado 1: rotulado de 1 - 6
Dado 2: rotulado de 1 - 8
Espaço amostral :
8 * 6 = 48
Probabilidade = resultado necessário / resultados possíveis totais
Resultado necessário = soma maior que 10 = 10
Resultados totais possíveis = 48
P (soma> 10) = 10/48
P (soma> 10) = 0,208333
20,8333 * 100%
= 20,833%
= 21%

y=-2x+4
y=-4x+2
y=4x+2
y=2x+4
Answer: y = 2x + 4
suppose: the equation of the line is y = ax + b(a ≠ 0)
the line passes through (0;4) and (-2;0) => 4 = b
-2a + b = 0
⇔ b = 4
a = 2
=> y = 2x + 4

Step-by-step explanation:
If JL = 16, KM = 4x-1, and KM is a perpendicular bisector of JL, determine which of the following values are correct. Select ALL that apply.
A.x = 3
B.JK = 11
C.KM = 15
D.KL = 17
E.Perimeter of triangle KLM = 22
F.Perimeter or triangle JKL = 50
*see attachment for diagram
Answer:
C.KM = 15
D.KL = 17
F.Perimeter or triangle JKL = 50
Step-by-step explanation:
Given:
JL = 16,
KM = 4x-1
JK = 6x - 7
KL = 5x - 3
✔️Thus, let's find the value of x
Since KM is a perpendicular bisector of JL, it means JM = LM = ½*16 = 8
KM in ∆KJM is equal to KM in ∆KLM.
The angles opposite the two corresponding congruent sides in both triangles are also congruent to each other. Therefore, the third corresponding side and angles would be congruent to each other.
Thus:
JK = KL
6x - 7 = 5x - 3 (substitution)
Collect like terms
6x - 5x = 7 - 3
x = 4
✔️Find JK:
JK = 6x - 7
Plug in the value of x
JK = 6(4) - 7
JK = 24 - 7
JK = 17
✔️Find KM:
KM = 4x - 1
Plug in the value of x
KM = 4(4) - 1
KM = 16 - 1
KM = 15
✔️Find KL:
KL = 5x - 3
Plug in the value of x
KL = 5(4) - 3
KL = 20 - 3
KL = 17
✔️Find the Perimeter of ∆KLM:
Perimeter of ∆KLM = KM + KL + LM
= 15 + 17 + 8
= 40
✔️Find the Perimeter of JKL:
Perimeter of ∆JKL = JK + KL + JL
= 17 + 17 + 16
= 50.
The correct values are:
C.KM = 15
D.KL = 17
F.Perimeter or triangle JKL = 50

Write a system of linear equations for the graph below.
We need to determine the equation of both lines first.
Line 1: y = -2x + 3Line 2: y = -1/3x - 2Now that we know the equations, we can set up a system of equations for this graph where both equations are in standard form.
Line 1:
[tex]y = -2x + 3\\\\2x + y = 3[/tex]
Line 2:
[tex]y = -\frac{1}{3}x - 2\\\\\frac{1}{3}x + y = -2[/tex]
Final answer:
[tex]2x + y = 3\\\frac{1}{3}x + y = -2[/tex]

HELPPP PLSSS NEED ANSWERS ASAP!! Thankyou so much in advance ❤️❤️❤️
does anyone know the answer to this question.....0.5x + 1.75 = 10
Answer:
x = 16.5
Step-by-step explanation:
0.5x + 1.75 = 10
Subtract 1.75 from both sides:
0.5x = 8.25
Divide both sides by 0.5
x = 16.5
Check your work!
0.5(16.5) + 1.75 = 10
8.25 + 1.75 = 10
10 = 10
x = 16.5

2x - y = -3
-2x - 8y = 12
Answer:
x= -2 y= -1
Step-by-step explanation:
stack the 2 equations on top of each other and add them together
the 2x and -2x cancel out and you are left with -9y=9
this gives you y= -1
you plug the y value into one of the equations:
2x - (-1) = -3
2x+1 = -3
2x= -4
x= -2
The following two-way table shows the data for the students of two different grades in a school:

Based on the relative row frequency, the students of which grade are more likely to be members of the public library?
The students of both grades are equally likely to be members of the public library
No conclusion can be drawn about the chances of a student being a member of the public library
Grade 7
Grade 6
Answer:
6th
Step-by-step explanation:
the chart says not, 7th has majority
The students of grade 6 are more likely to be members of the public library
What is probability?Probability is the ratio that shows the likelihood an event will occur or not from a given set of events.
The students of which grade are more likely to be members of the public library are determined below:Grade 6:
The total number of students who are a member of the public library = 25
The total number of students = 28
P(grade 6 students who are members of the public library.) = 25/28
= 0.892
Grade 7:
The total number of students who are a member of the public library = 23
The total number of students = 30
P(grade 6 students who are members of the public library.) = 23/30
= 0.767
We can see that grade 6 students are more likely to be members of the public library.
Therefore, we have found that the students of grade 6 are more likely to be members of the public library.
