Answer:
Step-by-step explanation:
Subtract 2x
from both sides of the equation.
y=8−2x
x−y=2
Replace all occurrences of y
in x−y=2 with 8−2x
.
y=8−2x
x−(8−2x)=2
Simplify the left side.

y=8−2x
3x−8=2
Solve for x
in the second equation.

y=8−2x
x=103
Replace all occurrences of x
in y=8−2x with 103
.
y=8−2(103)
x=103
Simplify 8−2(103)
.
Tap for more steps...
y=43
x=103
The solution to the system of equations can be represented as a point.

Answer:
<u>4</u>
Step-by-step explanation:
Answer:
speed = 32km/hr
Step-by-step explanation:
Time
10:15 to 10:30 = 1/4 hr
speed = distance/time
speed = 8 / (1/4)
speed = 32km/hr
For this case we have the following equation of a line:

To find the point of intersection with the x axis, we make y = 0:

We clear the value of "x":

So, the x-intercept of the line is 5.
To find the point of intersection with the y axis, we make x = 0:

We clear the value of "and":

So, the y-intercept of the line is 20.
Answer:

2+x^3=18
x^3=18-2
x^3=16
x=2.52
