Clean up the equation with x first and x=12.
Substitute this value in to the other equation to solve for y.
You should get a solution of (12,-8)
Answer:
The equation is: y = 1/2x + 7
Step-by-step explanation:
The slope of j is -2. The slope of a line perpendicular to line j has a negative inverse: 1/2. The point is (-8, 3).
Use the point slope form of the equation:
y - y1 = m(x - x1)
Substitute:
y - 3 = 1/2(x - (-8))
y - 3 = 1/2x + 4
y = 1/2x + 4 + 3
y = 1/2x + 7
Proof:
Solve for f(x) when x = -8.
f(x) = 1/2x + 7
f(-8) = 1/2(-8) + 7
= -8/2 + 7
= -4 + 7
= 3, giving the point (-8, 3)
The gial is to isolate the variable taht is the first thing to remember, second whatever you do to one side you must do to the other. yiu can approach this.in two ways as I see it with 1b or alk fractions. I prefer fractions so first you want yo get rid of the 9/4 on the variabke side so 9/4-9/4 is zero and 7/4-9/4=(-2/4) then you have 1/2b=(-2/4) or (-1/2) so you multipke both sides by two and get b=(-1) hope that helped
Step-by-step explanation:
Carmen's water bottle = 1.8 litres ≈ 2 litres
Jorge's water bottle = 2
= 2.4 litres ≈ 2 litres
Therefore, from estimate, Jorge's water bottle<u> does not</u> hold half litre more of water than Carmen's.
<u>Actual difference</u> = 2.4 - 1.8 = 0.6 litres
