Answer:
y= -2/3x+490
slope: -2/3
y-intercept: 490
Step-by-step explanation:
Y-intercept form is y=mx+b, so you would first subtract 2x from both sides to get 3y= -2x+1,470. Then you divide both sides by 3, to get y= -2/3x+490. -2/3 is in the place of m, so it is the slope, and 490 is in the place of b, so it is the y-int.
84÷2.8 =3.0 that's what I did when I learned it
I think it is 0.09375 cubic inches
Assuming the two angles are supplementary, the angle measuring x is equal to 33.75, and the angle measuring 3x+45 is equal to 146.25.
Step-by-step explanation:
x+(3x+45)=4x+45=180
4x+45=180
-45 -45
4x=135
÷3 ÷3
x=33.75
3x+45=146.25
the circle is 5; the triangle is 2; and the square is 6
