Answer:
46
Step-by-step explanation:
Since we know the value of the variable c, we can substitute 20 for c
2c + 6
2(20) + 6
40 + 6
46
Answer:
y = -x and 2y = 3x - 10 is the system of equations.
Step-by-step explanation:
Let,
Larger number = x
Smaller number = y
According to given statement;
x + y = 0
y = -x
And
3x - 2y = 10
Or it can be written as;
2y = 3x - 10
Therefore,
y = -x and 2y = 3x - 10 is the system of equations.
Explanation:
The formula for calculating the distance between two points is:
d=√(x2−x1)^2+(y2−y1)^2
Substituting the values from the points in the problem gives:
d=√(7−2)^2+(4−−6)^2
d=√(7−2)^2+(4+6)^2
d=√5^2+10^2
d=√25+100
d=√125
d=√25⋅5
d=√25√5
d=5√5
