Answer:
He scored a 4/10, 40%, .40
Step-by-step explanation:
4 out of 10 tells you what the fraction is. You might need to also list 40/100 just to be safe.
to make a fraction a parcentage you turn the fraction into a part of 100 and then take the top half and put a parcent symbol behind it, hence 40%.
to make a parcentage a decamle you move the decamle point two places to the left, making .40 or .4

Answer:
y = (3/2)x + 8
Step-by-step explanation:
Hi
First let's find the slope of the given line by converting to slope-intercept form:-
2x + 3y = 9
3y = -2x + 9
y = (-2/3)x + 3
From this we see that the slope is -2/3.
The slope of a line perpendicular to this one will be - 1 / (-2/3)
= 3/2. ( because for a line and its perpendicular, the slopes' product = -1).
Using the point-slope form to find the equation of this line
y - y1 = m(x - x1). Here m = slope and (x1, y1) is a point on the line.
Plugging in the given values , m = 3/2 , x1 = -2 and y1 = 5:-
y - 5 = 3/2 (x - -2)
y - 5 = 3/2x + 3
y = (3/2)x + 8 which is the equation in slope-intercept form.
