Erm..
9 I guess..
Good luck?
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
Step-by-step explanation:
To write 5 as a fraction with a common denominator, multiply by 55 . Combine 5 and 55 . Combine the numerators over the common denominator. Simplify the numerator.
Answer:
.
Step-by-step explanation:
A point of the form belongs to the graph of this function, , if and only if the equation of this function holds after substituting in and .
The question states that the point belongs to the graph of this function. Thus, the equation of this function, , should hold after substituting in and :
.
.
Solve this equation for the constant :
.
Thus, .
Answer:
-10
Step-by-step explanation:
= -X - XY
= -2 - 2×4
= -2 - 8
= -10
therefore, -X - XY = -10
