Answer:
x = 10/3
Step-by-step explanation:
3x = 2y + 14
y = -6x + 18
3x = 2(-6x+18) + 14
3x = -12x + 36 + 14
15x = 50
x = 50/15
x = 10/3
Answer:
<h2>r = 6</h2>
Step-by-step explanation:
18 - r = 12 <em>subtract 18 from both sides</em>
18 - 18 - r = 12 - 18
-r = -6 <em>change the signs</em>
r = 6
<em>Check</em>
18 - 6 = 12 <em>CORRECT</em>
Answer:
Step-by-step explanation:
let the speed of Landon=x
speed of Eduardo=x+9
5x+5(x+9)=135
divide by 5
x+x+9=135/5=27
2x+9=27
2x=27-9
2x=18
x=18/2=9
speed of Landon=9 mph
speed of Eduardo=9+9=18 mph
Answer with explanation:
We have to graph the Linear equation:
→ y-4 =x+2
⇒To draw a line you need two points that lies on the line.
→Point (-2,4) lies on the line,as
L HS→4-4=0
R HS → -2 +2=0
→From Point (-2,4) finding a point which is left 1 unit and down 3 units is equal to = (-2-1 ,4-3)
= (-3,1)
→And from Point (-2,4) finding a point which is left 3 unit and down 1 unit is equal to = (-2-3 ,4-1)
= (-5,3)
→None of the two points that is (-3,1) and (-5,3) lie on the linear function
which is, y-4 =x+2.
≡None of the option
Answer:
Almost Correct!
Step-by-step explanation:
The general form of the equation of a circle is: x2 + y2 + Dx + Ey + F = 0, where D, E, F are constants. No factor multiplies the terms x2 and y2.
