Answer:
use desmos and type in the equation to get the graph
Step-by-step explanation:
Answer:
one
Step-by-step explanation:
When a system of equations is graphed, the solution is the coordinate that is plotted at the intersection of the two lines.
If the two lines cross once, there is only one solution.
If the two lines are on top of each other then there are infinitely many solutions.
If the two lines are parallel ( and never touch ) then there are no solutions
By looking at the graph we notice the two lines intersect once. So we can conclude that there is only one solution.
ANSWER
EXPLANATION
The given equation is
We add the additive inverse of 31 which is -31 to both sides of the equation to get,
Simplify;
Answer:
Multiply 6 x 4 then add 10
or do the other way around
Step-by-step explanation:
Step-by-step explanation:
2 × 10⁸ - 7 × 10⁷
= 200,000,000 - 70,000,000
=130,000,000
= 1.3 × 10⁸
