This is the concept of algebra, to get the slope of the line we need to rewrite the equation in slope intercept form y=mx+c, where m=slope, c=y-intercept.
Therefore re-writing our expression in slope-intercept form we get:
7x-3y=10
-3y=-7x+10
y=7/3x-10/3
The slope=7/3
hence we conclude that the slope of the line perpendicular to this is -3/7
Answer:
(3x - 25y)(3x + 25y)
Step-by-step explanation:
9x² - 625y² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
Given
9x² - 625y²
= (3x)² - (25y)²
= (3x - 25y)(3x + 25y)
Based on the answer choices, we suspect you intend
.. (x -1) +26 = -4x
This simplifies to
.. x +25 = -4x
.. 25 = -5x . . . . . subtract x
.. -5 = x . . . . . . . divide by the coefficient of x
Selection D appears to be appropriate for the question we think you asked.
Answer:
RO = 39.5
Step-by-step explanation:
RO/9 = 57/13
13RO = 513
RO = 513/13
RO = 39.46
Im sorry buuuuuuuuuut um thats too small maybe zoom in.. ;/
