Answer:
(-18, -3)
Step-by-step explanation:
To solve this system of equations, use the substitution method.
Steps for substitution method:
Step 1 : First, solve one linear equation for y in terms of x.
Step 2: Then substitute that expression for y in the other linear equation. You'll get an equation in x.
Step 3: Solve this, and you have the x -coordinate of the intersection.
Step 4: Then plug in x to either equation to find the corresponding y -coordinate.
>; < - dot line
≥; ≤ - solid line
>; ≥ - shading above the line
<; ≤ - shading below the line
----------------------------------------------
y = 2x + 3 - it's a linear function. We only need two points to plot the graph. Select two any x values and calculate the y values:
for x = 0 → y = 2(0) + 3 = 0 + 3 = 3 → (0, 3)
for x = -2 → y = 2(-2) + 3 = -4 + 3 = -1 → (-2, -1)
y > 2x + 3
Dot line an shading above the line (look at the picture).
It would be (232 + 485) Km + (811+829)m
717 Km + 1640 m
Now, you know 1000m = 1Km
So, transfer that in Km, then it would become:
718 Km 640 m
Answer:
two solutions work: x = 5 +
and x = 5 -
Step-by-step explanation:
x + 6 ( 1/x ) = 10
x^2 + 6 = 10x
x^2 - 10x + 6 = 0
x = 5 +
, 5 -
