Answer:

When x=8, y=-6. When x=10, y=0

Step-by-step explanation:

y=3x-30\\x^2+y^2=100

You can plug the given y value into the second equation to get:

x^2+(3x-30)^2=100\\x^2+9x^2-180x+900=100\\10x^2-180x+800=0\\10(x^2-18x+80)=0\\10(x-8)(x+10)=0\\x= 8, 10\\y= -6, 0

Hope this helps!

I’m stuck... any one able to help?<br> X^4 + 5x^3 + 3x/x
Leni [432]

Answer:

x^3+5x^2+3x

Step-by-step explanation:

1) divide each term in the numerator by the term in denominator:

(remember when dividing subtract the smaller exponent from larger exponent

for example: \frac{x^a}{x^b} say a is the larger exponent, do x^a^-^b

x^4/x=x^3

5x^3/x=5x^2

3x^2/x=3x

so

x^3+5x^2+3x

hope this helps!

The length of the segment from a point c _____ to the line AB gives the distance from point c to the line ab brainly
guapka [62]

Answer:

A. Perpendicular

Step-by-step explanation:

When lines and/or points are in perpendicular to one another, the perpendicularity line between them measures the distance between both points and/or lines.

So to measure the distance between point c and line AB, a perpendicular line has to be drawn from c to AB or from AB to c. Either of these will arrive at the same result.

It should also be noted that the angle at the point of intersection of perpendicular lines is 90°.
