Hi there! Putting this equation into a slope-intercept basically means solving for y. Move everything besides the constant of y and y to the other side giving you 2y=-4x+4. Divide both sides by 2 to give you y alone. This gives you y=-2x+2
Hope this helped!
The additive inverse of a number is the opposite number......for this problem, it is a number, that when added to -4 1/4 = 0.
so the additive inverse of -4 1/4 = 4 1/4
x=11
x is equal to 11 because you subtract 4x from both sides and then add 8 to both sides where you are left with 2x=22. After dividing by 2, you get x=11
Answer:
Step-by-step explanation:
The angle of shaded sector = 360-332 = 28°
The radius of sector, r = 15 ft
We need to find the area of the shaded sector. The formula for the area of the sector is given by :
So, the area of the shaded sector is equal to 
.
Let us assume that the number of days she practiced the piano to be "d"
Since she practiced 2/3 hours a day, the total number of hours would be: 2/3*d
Now we are given the total number of hours during summer that she practiced be be equal to 32/23
So we equate 2/3 * d to 32/23 to find d
2/3*d = 32/23
d = (32/23)/ (2/3)
d = (32/23) * (3/2)
d = 48/23 hours
The equation that can be used to find the number of days that she practiced piano during the summer is 2/3*d = 32/23
