Answer:
9
Step-by-step explanation:
The first sentence of the problem can be interpreted two ways. The way that makes the second sentence work out correctly is ...
'a larger number is 5 less than 3 times a smaller number'
Using x for the smaller number, the two equations that can be written are ...
Adding 4 times the first equation to the second, we get ...
4(3x -y) + (x +4y) = 4(5) +(97)
13x = 117 . . . . . simplify
x = 9 . . . . . . . . divide by 13
The smaller number is 9.
Answer:
y = -2/3x + 4/3
Step-by-step explanation:
If two lines are perpendicular, the product of their slopes is -1
comparing what we have with the general form;
y = mx + b
The slope of the given equation is 3/2
To get the slope of other;
3/2 * m = -1
3m = -2
m = -2/3
So we want to write the point-slope equation
y-y1 = m(x-x1)
y-2 = -2/3(x + 1)
3y - 6 = -2x -2
3y = -2x -2 + 6
3y = -2x + 4
y = -2/3x + 4/3
Answer:
-1k +27 is the answer. 13k-14k= -1k 11 +16= 27

Answer:
3.77
Step-by-step explanation:
A= L × W
52=(W + 10)W
52= W^2 + 10W
0 = W^2 + 10W - 52
Factor from here using quadratic formula to find the roots:
W = 3.77
or
W = -13.77
Dimensions of a shape cannot be negative, therefore it's approximate width is 3.77yd.
