Answer:4times 10
Step-by-step explanation:
First we need to find slope of given line −4x+3y=−2
So convert it into slope intercept form y=mx+b
−4x+3y=−2
3y=4x−2
y=4/3x−2/3
Comparing above equation with y=mx+b gives m=4/3
Hence slope of given line is 4/3.
<em>We need slope of perpendicular line which is always "negative reciprocal of given slope"</em>.
Negative of 4/3 is -4/3.
taking reciprocal gives -3/4
Hence slope of required perpendicular line is m=-3/4
-------
Now we need to find y-intercept of −7x−7y=6
y-intercept is always the y-value when x=0 so let's plug x=0 into −7x−7y=6
−7(0)−7y=6
0−7y=6
−7y=6
y=-6/7
y-intercept is also called "b" in y=mx+b
hence b=-6/7
-----
Now we know that slope of perpendicular line is m=-3/4 and y-intercept b=-6/7
so plug both into formula y=mx+b
We get Final answer is
Answer:
There would be 875 teachers.
Step-by-step explanation:
8/5 equals 1.6.
1400 students / 1.6 = 875 teachers.
To check your work: 1400 students / 875 teachers = 1.6, which is the same ratio as 8 to 5.
<em>Hope this helps!</em>
Answer:
X = 6
Step-by-step explanation:
Add 14 to both sides: 18 = 3a
Divide both sides by 3: a = 6
Im still trying to figure that answer out.. its hard
