Which ordered pair is a solution to the system of linear equations Negative 4 x + y = 8 and x minus 5 y = 17?
(–4, –3)
(–4, 3)
(–3, –4)
(–3, 4)
The solution to the linear equations will be ( -3, -4 ).
What is linear equation?The equation whose highest degree of the variable used in the equation is 1 is called linear equation.
For example 12x+5y=19 is a linear equation.
We have,
- 4x + y = 8 .....(i)
x - 5y = 17 .....(ii)
Now,
Rewrite equation (ii) ,
x - 5y = 17
⇒ x = 5y + 17 .....(iii)
Now substitue this value of x in equation (i) i.e. - 4x + y = 8
We get,
- 4(5y + 17) + y = 8
- 20y - 68 + y = 8
- 19y - 68 = 8
- 19y = 8 + 68
-19y = 76
⇒ y = - 4
So, we have a value of y now substitute this equation (iii),
We get,
x = 5(-4) + 17
x = - 20 + 17
x = - 3
So,
The solution to the given linear equations is ( -3, -4 ).

Answer:
B. y = 1/2x - 2Step-by-step explanation:
The slope-intercept form is:
y = mx + bAccording to the table, point (0, -2) we see:
y-intercept is - 2And using two points (4, 0) and (8, 2) we can find the slope:
m = (2 - 0)/(8 - 4) = 2/4 = 1/2So the line is:
y = 1/2x - 2Correct option is: B

Given the graph below write the equation of the line.
y = 2 + 2
y = -2x
y = 2x + 8
y = 0x + 8
Answer:
y = 2x+8
Step-by-Step Explanation:
The equation should be in the form of y=mx+b
So you already know it's not A. Also you already know it's not D because the line goes at an angle, if "m"(slope) was 0 then the line would be straight horizontal or straight vertical. So that leaves B and C. And finally you know it's not B because the line is going in the positive direction not negative, so the slope has to be positive, also "b" in the equation is the y-intercept, and that's where the line intersects with the y-axis, and you can see that the line intersects at 8 on the graph. Therefore, the answer is C, y=2x+8

Ming incorrectly says that this product is 4/63.
-(-4/9) · (-1/7)
a. What is the correct product?
b. What error could Ming have made?
Answer: -4/63
Step-by-step explanation: he put a positive sign instead of a negative in the 4
a. The correct product is -4/63.
b. Ming forgot to distribute two negative signs on the first term.
Sign changes when we do arithmetic operations ?(-,-) = +. (+,+) = +. (-,+) = -. (+,-) = -.
For example -: 6 + (-3) here negative sign of 3 will distribute (+,-) and the end result will be negative ⇒ 6 - 3 = 3
According to the given question
Ming has given a product -(-4/9) · (-1/7) and he mistakenly said it is 4/63.
The given product is -(-4/9) · (-1/7)
= (4/9).(-1/7)
= -4/63.
Ming didn't notice that on the first term two negative sign will distribute and make it positive and then multiplying it with a negative number will result in a negative number.

Raul’s grandfather is Miguel, and Raul’s sister is Paula. Raul’s age is the same as his grandfather’s age minus 60 times the age of his sister. Miguel is 65 years old. Using the results from Part C, write an equation to find Paula’s age, p (in years).
Previous equation answer:
Yes the values are the same
3r = 45
3(15) = 45
Answer:
3(15)+60p+65=45
Step-by-step explanation:
Paula’s age, p is 5/6 years.
Given that, Raul’s grandfather is Miguel age=65 years.
How do solve age problems?Important Statements and Equations for "Problems based on Ages":
If the present age is y, then n times the present age = ny.If the present age is x, then age n years later/hence = x + n.If the present age is x, then age n years ago = x – n.The ages in a ratio a: b will be ax and bx.If the current age is y, then 1/n of the age is y/n.Let Raul’s sister Paula's age be p and Raul’s age be r.
From the statement, Raul’s age is the same as his grandfather’s age minus 60 times the age of his sister.
We can write the equation as follows r=65-60p
In part C:
39=3r-6
⇒r=15
So using the part C answer we get 15=65-60p
⇒60p=65-15
⇒p=5/6 years
Therefore, Paula’s age, p is 5/6 years.
