Here are the steps to solve it:
-6+3x= -9
3x= -9+6
3x÷3= -3÷3
x= -1
Your answer is x = -1
They scored 0 goals in the 2 half of the game
Odd integers are 2 apart
they are
x,x+2,x+4
sum is -75
x+x+2+x+4=-75
3x+6=-75
minus 6 both sides
3x=-81
divide both sides by 3
x=-27
x+2=-25
x+4=-23
the largest is the farthest to right on a number line
largest is -23
x2+y2−2x−80=0
Write the problem as a mathematical expression.x2+y2−2x−80=0
Add 80 to both sides of the equation. x2+y2−2x= 80 Complete the square for x2− 2x. Tap for more steps...(x−1)2−1 Substitute (x−1)2−1 for x−2x in the equation x2+y2−2x =80 .(x−1)2−1+y2=80 Move −1 to the right side of the equation by adding 1 to both sides.(x−1)2+y2=80+1Add 80 and 1.(x−1)2+y2=81
This is the form of a circle. Use this form to determine the center and radius of the circle.(x−h)2+(y−k)2=2Match the values in this circle to those of the standard form. The variable r represents the radius of the circle, h represents the x-offset from the origin, and k represents the y-offset from origin.r=9h=1k=0 The center of the circle is found at (h,k). Center: (1,0)These values represent the important values for graphing and analyzing a circle. Center: (1,0)Radius: 9
Answer:
Step-by-step explanation:
The way i estimate is i first look at the dollars and i mutiply that by 4 ($1x4)
you get 4 then we look at the cent which is $0.98 i would add in about 4 times and i would get to about $3 maybe. (This is mental math)
After that add 4 and 3 and you get 7
the estimated cost is about 7-8 dollars.
exact cost is-7.92
