6 miles.
3 miles per hour times 2 hours.
3 x 2 = 6.
Answer:
Step-by-step explanation:
x+y=17 is NOT the equation for any circle. You have omitted the exponents. The equation for the circle should be
x^2 + y^2 = 17.
:::::
Plug the coordinates of D into the equation.
(-4)² + (-1)² = 17, so D is on the circle.
Plug the coordinates of E into the equation.
1² + 4² = 17, so E is on the circle.
:::::
Slope of DE = (-1 - 4)/(-4 - 1) = 1
Slope of perpendicular to DE is -1.
Midpoint of DE: ((-4+1)/2, (-1+4)/2) = (-1.5, 1.5)
Point-slope equation for perpendicular bisector:
y-1.5 = -(x+1.5)
y = -x
:::::
Center of circle is (0,0)
0 = -0, so y=-x passes through the center.
Answer:
x = 67.5°
Step-by-step explanation:
A circle's angles add up to 360°
So,
x+3x+90 = 360
4x+90 = 360
4x = 360-90
4x = 270
Dividing both sides by 4
x = 67.5°
Answer:
2 cakes
Step-by-step explanation:
Lets divide these fractions (when dividing, remember keep, change and flip): 36/4 * 2/9 = 2
I hope this helps, please mark Brainliest, thank you !!
Your answer is: y=5
Here are the steps:
<span>4=2/9(4y-2)
=2/9(4y-2)=4
=9*</span>2/9(4y-2)=4*9
=2(4y-2)=36
=2(4y-2)/2=36/2
=4y-2=18
=4y-2+2=18+2
=4y=20
=4y/4=20/4
=y=5
