y =2x-1
Step-by-step explanation:
For this case we have that by definition, the slope of a line is given by:
Where:
They are two points through which the line passes.
According to the statement we have two points:
Substituting we have:
Thus, the slope of the line is:
Answer:
Factor 25 out of 25a^2−100.
Factor 25 out of 25a^2.
25(a^2)−100
Factor 25 out of −100.
25a^2+25⋅−4
Factor 25 out of 25a^2+25⋅−4.
25(a^2−4)
Rewrite 4 as 2^2.
25(a^2−2^2)
Factor.
Since both terms are perfect squares, factor using the difference of squares formula, a^2−b^2=(a+b)(a−b) where a=a and b=2.
25((a+2)(a−2))
Remove unnecessary parentheses.
25(a+2)(a−2)
I believe this is correct.
Answer:
x=1
y=-2
Step-by-step explanation:
In Picture
Please give brainliest, thanks!
This is an isosceles triangle: a triangle with two sides equals.
Therefore:
side BA=side CA
8x-4=5x+11
8x-5x=11+4
3x=15
x=15/3
x=5
length of side BC=4x-2=4(5)-2=20-2=18.
The lenght of side BC is 18 units of lenth.
