Answer:
The equation would be y = 2x + 3
Step-by-step explanation:
In order to solve this, we first need to find the slope of the line between (-2, 5) and (2, 3). In order to do this, we use the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (3 - 5)/(2 - -2)
m = -2/4
m = -1/2
Now that we have the original line with a slope of -1/2, we can tell a perpendicular line would have a slope of 2. This is because perpendicular lines have opposite and reciprocal slopes. Now we can use that slope and the given point in point-slope form to get the answer. Be sure to solve for y.
y - y1 = m(x - x1)
y + 7 = 2(x + 5)
y + 7 = 2x + 10
y = 2x + 3
56 students represents 100 % and
X boys represent 34%,
so x= 56•34/100= 19.04 so approximately 19 boys
56-19= 37 girls signed up.
Now 37 girls represent 100% and 31 girls represent x % ,
So x= 31•100/37= 83.78% about 84% of the girls attended
A) a=3x8
a= 24
B) b=8 divide by 4
b= 2
