Option C
Step-by-step explanation:
I took this before
Answer:
10x- 6y
Explanation:
Multiply the 2 with what’s inside the parentheses
(-2x + 4y)(3x - 7y) = -6x^2 - 28y^2 + 12yx
Answer:
C. About 22
Step-by-step explanation:
13.3 + 2.8 + 5.6
= 21.7
Since 21.7 is close to about 22, we can conclude that C is the final answer.
Answer:
m=3/4
Step-by-step explanation:
first, let's put the line 4x+3y=9 from standard form (ax+by=c) into slope-intercept form (y=mx+b)
we have the equation 4x+3y=9
subtract 4x from both sides
3y=-4x+9
divide by 3
y=-4/3x+3
perpendicular lines have slopes that are negative and reciprocal. If the slopes are multiplied together, the result is -1
so to find the slope of the line perpendicular to the line y=-4/3x+3, we can take the slope of y=-4/3x+3 (-4/3) multiply it by a variable (this is our unknown value), and have that set to -1
(m is the slope value)
-4/3m=-1
multiply by -3/4
m=3/4
therefore the slope of the perpendicular line is 3/4
hope this helps!! :)
