D
Step-by-step explanation:
Took the test on edge2020
Answer: Let x = the length of a side of the square
a2 + b2 = c2
x2 + x2 = 102
2x2 = 100
x2 = 50
x = √50
x = 5√2 cm
Step-by-step explanation:
2/9 3/5 5/7 is the correct answer
Multiply 5 and y
Multiply 1 and y
The y just gets copied along.y
Differentiate yx with respect to x.
Apply the "power rule" to x (the derivative of xn=nxn-1) giving 1
Multiply 5 and y
Multiply 1 and y (-8)
The answer is 5y
The final answer 5xy
hope this will help u :)
sorry if there is any mistakes.. ;)
Answer:
3x + 5y = 1
Step-by-step explanation:
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (2, - 1) ← 2 points on the line
m =
= -
y = -
x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (2, - 1), then
- 1 = -
+ c ⇒ c = - 1 +
= 
y = -
x +
← in slope-intercept form
multiply all terms by 5
5y = - 3x + 1 ( add 3x to both sides )
3x + 5y = 1 ← in standard form
