Answer:
<h2>x = 8 and y= 12</h2>
Step-by-step explanation:
For x use the Pythagorean theorem:
<em>subtract 36 from both sides</em>
We know: x + y = 20. Substitute:
<em>subtract 8 from both sides</em>
Y = mx + b
m = slope of the line
b= y-intercept
Since you are given the point (4,1/3), the y-value is 1/3.
So plug in the numbers and solve for b:
(1/3)= (3/4)*(4) + b
After you solve the equation for b, you should get -2 2/3 or -8/3
No rewrite the equation with the y-intercept, b.
y = (3/4 x) - (8/3)
The answer is 2-4 because it all comes togwthe
Answer:
(x,y)=(-1,-4)
Step-by-step explanation:
y=–3x–7
y=x–3
(y=)-3x-7=x-3
-3x-x=-3+7
-4x=4
x=4/(-4)
x=-1
y=x-3
y=-1-3
y=-4
(x,y)=(-1,-4)
