There were 7 cakes
So each person ate 1/6 of a cake right! So that means if took 6 people to eat 1 cake. But there were 42 people there. So we do 42 divided by 6 =7
So there were 7 cakes
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
x = 11,1.
Answer:
Step-by-step explanation:
Relations are only functions if they do not share any x values at all! The 2 graphs there that do not have any of the same x values are graphs A and D. Notice that on graph B, there are several y values that share the x value of 2; on graph C, there are several y values that share the x value of 2.
slope = y2-y1 / x2-x1=
-1 -5 / 2 - -1 = -6/3 = -2
slope = -2
y intercept = y =mx +b
y = -2x +b
y=-2*-1 +b
5 = -2 +b
b = 5-2
b =3
y intercept = 3
3x10 equals 30. The .4 is in the tenths place so multiplied by 10 will move it to the ones place.
