Answer: y=2x-23, x=8; (8, -7)
Step-by-step explanation:
First, arrange both equations in y=mx+b form and evaluate; y=2x-23 & x=8
Now, use x=8 to substitute the value into the y=2x-23 equation;
y=2(8)-23, this will give you a completed ordered pair;
(x=8, y=-7)
Hope this helps !
x+y=8+(-7)
=1
Answer:
Step-by-step explanation:
The line rises to the left so the slope is negative.
The slope m = -24/12 = -2.
Using the point-slope formula and taking the point (12, 0) on the line:
y - y1 = m(x - x1) where m = -1, x1 = 12 and y = 0:
y - 0 = -2(x - 12)
y = -2x + 24 <------- this is the required equation.
Answer:
X= -12
Step-by-step explanation:
So just combine like terms and isolate the variable
5x+2=6x+14
2=x+14
-12=x
So x is negative twelve

The value of x is 8 when y = 12 if variables x and y have proportional relationship.
According to the given question.
Variables y and x have proportional relationship.
⇒ y ∝ x
Let k be the constant of proportionality.
⇒ y = kx
Also, it is given that
y = 21 when x = 14
Substitute the value of y = 21 and x = 14 in y = kx to find the value of k.
21 = k(14)
⇒ k = 21/14
⇒ k = 3/2
Therefore, the value of x when y = 12
y = kx
⇒ 12 = (3/2)x
⇒ 12 × 2 = 3x
⇒ 24 = 3x
⇒ x = 24/3
⇒ x = 8
Hence, the value of x is 8 when y = 12.
