Answer:
y = -4x + 5
Step-by-step explanation:
y = -4x + b
-3 = -4(2) + b
-3 = -8 + b
5 = b
H^2=x^2+y^2 and xy=168 so y=168/x
625=x^2+28224/x^2
625=(x^4+28224)/x^2
x^4-625x^2+28224=0
I'll use the quadratic because this is a big number :P
x^2=(625±√(277729))/2
x^2=(625±527)/2
x^2=49
x=7
168/7=24
So the dimensions of the painting is 7 inches by 24 inches.
Answer:
<h2>
(0, -5)</h2>
Step-by-step explanation:
We need to convert function to slope-intrcept form y=mx+b, where:
3x - 5y = 15 {subtract 3x from both sides by 20}
-5y = -3x + 15 {divide both sides by (-5)}
y = 3/5x - 5 ⇒ <u> b = -5
</u>
Therefore y-intercept of the line is (0, -5)
