A²+b²=c²
39²+b²=89²
1521+b²=7921
subtract 1521 from both sides
b²=6400
so then you square both sides
√6400
80
We are looking for k in the equation
(x+4)(x+k/4) = x^2+7x+k
The left hand side expands to:
x^2+(4+k/4)x+k = x^2+7x+k
Comparing coefficients for the linear terms, we have the equation
(4+k/4)=7
Solving for k:
16+k=28
k=12
Thus the number to be subtracted is 15-k=15-12=3
Answer:
A table that represents a linear equation should be your answer. This means your slope should be constant/straight not like a parabola or absolute function.
Step-by-step explanation:
When you're trying to solve something using slope-intercept you can graph it or plug numbers for (x,y).
Graph:
Start at (0,-3)
Then plot the point since that is your Y-Intercept
Then go 5 up and 4 over to find your next point.
Once done, you should connect the dots to form a slope or a linear equation.
Answer:
The answer is 113 as we find angle qps and then x by alternate angle property.
